https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/220.127.116.11 Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that. Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap. We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout. Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.
Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now. Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date. The transition height is also when the team requirement will be relaxed for the network.
Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.
The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use. There are so many goodies here it is hard to summarize them all. I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures. The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!
Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.
Network magnitude unit pinned to a static value of 0.25
Max research reward allowed per block raised to 16384 GRC (from 12750 GRC)
New CPIDs begin accruing research rewards from the first superblock that contains the CPID instead of from the time of the beacon advertisement
500 GRC research reward limit for a CPID's first stake
6-month expiration for unclaimed rewards
10-block spacing requirement between research reward claims
Rolling 5-day payment-per-day limit
Legacy tolerances for floating-point error and time drift
The need to include a valid copy of a CPID's magnitude in a claim
10-block emission adjustment interval for the magnitude unit
One-time beacon activation requires that participants temporarily change their usernames to a verification code at one whitelisted BOINC project
Verification codes of pending beacons expire after 3 days
Self-service beacon removal
Burn fee for beacon advertisement increased from 0.00001 GRC to 0.5 GRC
Rain addresses derived from beacon keys instead of a default wallet address
Beacon expiration determined as of the current block instead of the previous block
The ability for developers to remove beacons
The ability to sign research reward claims with non-current but unexpired beacons
As a reminder:
Beacons expire after 6 months pass (180 days)
Beacons can be renewed after 5 months pass (150 days)
Renewed beacons must be signed with the same key as the original beacon
Magnitudes less than 1 include two fractional places
Magnitudes greater than or equal to 1 but less than 10 include one fractional place
A valid superblock must match a scraper convergence
Superblock popularity election mechanics
Yes/no/abstain and single-choice response types (no user-facing support yet)
To create a poll, a maximum of 250 UTXOs for a single address must add up to 100000 GRC. These are selected from the largest downwards.
Burn fee for creating polls scaled by the number of UTXOs claimed
50 GRC for a poll contract
0.001 GRC per claimed UTXO
Burn fee for casting votes scaled by the number of UTXOs claimed
0.01 GRC for a vote contract
0.01 GRC to claim magnitude
0.01 GRC per claimed address
0.001 GRC per claimed UTXO
Maximum length of a poll title: 80 characters
Maximum length of a poll question: 100 characters
Maximum length of a poll discussion website URL: 100 characters
Maximum number of poll choices: 20
Maximum length of a poll choice label: 100 characters
Magnitude, CPID count, and participant count poll weight types

How to Cold Store Your Cryptocurrency for Safekeeping
According to CipherTrace (which specializes in litigation tools and services for cryptographic markets), between 2018 and 2019, the amount of theft from cryptographic wallets exceeds $2 billion. Thefts and break-ins are caused by a variety of reasons: simple incompetence in cryptographic storage, as well as by companies that provide storage services. It is not unusual for holders of crypto currency to lose access to their wallets by themselves, one of the last known cases occurred in Ireland: ,57 million dollars couldn’t be confiscated from a detained drug dealer, which were stored in bitcoins. The problem was that the wallets keys were lost. The most secure way is a cold storage — all account data and private keys are kept offline and all transactions are manual. This storage method is great because it is fully protected from hacking and interception of data, but it is not suitable for those who make daily transfers of cryptocurrency, it is simply inconvenient. If you compare “cold and hot” wallets, you can give a simple example: A hot wallet can be compared to a wallet that can be lost and stolen. But you can always access your funds. A cold wallet is safe, and access to it is not permanent. You can also take or put money, but it will require a special code. In this article we will tell you about the most popular types of cold wallets and we will analyze their pros and cons.
Types of cold wallets
All cold wallets have one common thing — the data is stored offline. However, there are several types of cold wallets, which differ in the degree of protection, physical embodiment and cost of the wallet.
Desktop wallets are also known for a high level of protection, in addition to the ability to store crypto currency offline. There are so-called “light” wallets weighing less than 1 gb, and “heavy” wallets weighing more than 1 gb. Two of the desktop wallets can be distinguished:
Multicurrency wallet. It was created in 2016 and supports more than 100 crypto currencies, since 2019 has a phone application. The wallet allows you to export private keys that are created locally, and then to upload them back. Private keys can be discounted to removable media and downloaded only when the transaction is completed. If the user decides to leave private keys on the same computer where the wallet is located, keys are securely encrypted. In order to use your wallet ,there is no need to register or to download the entire blockchain — synchronization is taking place online. In addition to wallet services Exodus Wallet provides an integrated crypto-exchange. The installation file weighs 85 mb.
Bitcoin Core is the official Bitcoin wallet. The size of the wallet is 160 gb, but according to the developers of the company, it’s better to give it a separate winchester with the size of 500 gb. From the security viewpoint, it’s suggested to install a security code or a seed phrase, which may consist 8 words. It is also suggested to copy wallet.dat file. — private wallet key, which will allow you to restore access to your funds.
Appears like a regular flash drive with an interface (screen, control keys). This wallet can safely store information about the balance and keys, full functionality is available only when connected to a computer, but the latest models have a special button that allows you to confirm the transaction without connecting to a PC. Each time the device offers to generate a new code-password to confirm the transaction, which significantly reduces the probability of hacking. After generating the code, you need to set a mnemonic phrase (seed) — it consists of 12 or 24 words, which are not related to each other in any way. Such type of wallets has a special protection system that allows you to connect even to potentially infected PCs. The wallets themselves won’t be affected by malware. The obvious cons of hardware wallets are the following:
It is also possible to lose a device that is so small in size.
A physical device can easily fail due to a variety of damages.
It is not recommended to buy such wallets from “hand”, even from friends, as they can be pre-installed with malware.
As you can see, storing crypto currency with a hardware wallets is very safe and secure, however you should take care about the device. Many people who hold a large amount of crypto currency, in order to not to lose a hardware wallet, store it in a safe deposit box, depriving someone of access to it.
Popular Hardware Wallets models
The first hardware wallet produced in 2013 by the Czech company Satoshi Labs. The device has an OLED display with a pin code, public addresses and Seed phrases. Trezor One has won recognition from users due to its multicurrency and affordable price ($65), it is also considered one of the most secure hardware wallets. Ledger Nano S The wallet was released in 2016 by the French company Ledger SAS. Distinctive feature from the other wallets, is the Secure Element controller, which meets banking standards and is certified CC EAL 5+. Also, in order to work with each crypto currency you need to install a special application for this currency on the device, it is not quite convenient, however more secure. The average price of the device is $85. KeepKey The purse was released in 2015 in the U.S.. Distinctive feature is OLED display — 256 by 64 pixels. Due to this, you can fully see both the address of the wallet, and the seed phrase. Also, the wallet has a built-in exchange service ShapeShift — an opportunity to exchange crypto currency without entering the exchange. The average price of the device is $50. BitBox01 Ionos Schnelly’s wallet was invented in Switzerland. In size it’s almost the most compact among all representatives of the hardware wallets. A distinctive feature is the availability of a backup — the card can be multiplied and kept in several places, by analogy with the seed-phrase. In November 2020, support for these wallets will be discontinued, but all owners will be given a 30% discount on the new model. The average price of the device is $55. CoolWalletS Developed in Taiwan by CoolBitX, which has long been manufacturing components for Visa and MasterCard. As well as Ledger Nano S has a security standard CC EAL 5+. This wallet works only through smartphones, connecting to them through Bluetooch. The average price of the device is $100.
In the age of technological process, plain paper has become a rather reliable method for storing cryptocurrency. With the help of special services, such as bitaddress.org, you can generate public and private keys, then writing them down on paper. You can also print keys as a QR code. To accept transactions with such a wallet, you provide the sender with a public key. To access the funds, you need to find any online wallet that supports your crypto currency. Enter your private key into your online wallet, thus integrating your funds into the system. However, you should understand that after this procedure your wallet will become “hot”. The best of this storage method — paper wallet is free, its safety depends only from you. When storing a paper wallet to protect it from the fire, water and aging. Also, do not tell other people about where your paper wallet is hidden. The disadvantages of this storage:
If your wallet is lost, it will be impossible to restore it.
Exposed to a physical damage.
After sending the transaction, you will have to create a new cold wallet.
Offline transaction signature
For this storage method, you will need two PCs. The essence is that the secret keys are never in contact with the Internet, but are stored digitally. Offline transaction method is suitable for people who do not make a daily transactions and have an access to two devices. The process is below:
A hot wallet is installed on a PC with the Internet. The transaction is created without entering private keys and authorization.
The file with transaction is copied and transferred to the second PC without Internet, where private keys are stored.
The transaction is signed offline, copied and transferred back to the PC with the Internet.
In fact, you can do it with one PC and a USB drive. The USB drive will store private keys. Also, you can create a transaction without entering private keys and authorization, after disconnecting the Internet, connect the flash drive, sign the transaction, turn on the Internet. In this case, you should take care of the antivirus system. The disadvantages of this method:
Using two PCs or a USB drive involves a lot of actions, which is time consuming.
You need to back up your keys in case your PC or flash drive fails.
This method implies the creation of a wallet, which can be only withdrawn on condition that the transaction is verified by a predetermined number of users. The maximum number of users who can hold private keys of the wallet- is 15. It is considered as one of the most reliable ways of storage, in fact private keys are not only stored offline, but also divided between different people. Often the wallet with multisignatures is used by large crypto-companies, whose management believes that individually employees can not spend the budget. Moreover, when creating this wallet, the number of required multisignatures is minimal. For example: if one of the six keys is lost, the remaining ones will be enough for the transaction. The disadvantages of this storage:
If most of the keys are lost, access to the funds cannot be restored.
You will not be able to make transactions on your own without the participation of other key holders.
Private Key Fragmentation
The private wallet key consists of 64 symbols. The key is divided into several fragments. They don’t represent anything separately, but if you put all the fragments together, you can access the funds. The key fragments are similar to multisignatures, but in this case you don’t need a multisig-wallet, and the whole process can be done manually. The disadvantages of this method:
If one fragment is lost, access to funds will be lost.
The maximum level of protection can only be reached when key fragments are distributed to different places, for example: bookshelf, safe deposit box, car. If you divide the key fragments and put them in different boxes — the required level of protection will not be achieved.
When writing down key fragments on paper, protect the key from fire, water and aging.
Digital currencies are not physically expressed and exist only in the digital code, so cold wallets that doesn’t have an access to the Internet, protect cryptocurrencies from the most important and common problem — hacker theft. However, holders of cold wallets need to understand that the safety of a private key depends only on them. There are different ways to store private keys outside the network, but each of them makes it difficult for the user to make transactions. Hardware wallets that have been specifically designed for this purpose are considered to be the best option for storing cryptocurrencies. With their help it is possible both to store funds off the network and to make transactions easily, without risking the safety of a private key. If you use other cold wallets, it is recommended to combine them with hot wallets. Keep the required crypto currency for daily transfers on hot wallets, and keep all other crypto on cold wallets.

Have a wallet.dat from a mining pool back around 2010. Had coins on it but can't get it open. Can anyone help me out?
Back around 2010/2011 I mined some bitcoins using one of those mining pools. I've tried to figure out which I used, but can't. I kept the wallet.dat even after all these years but have long forgotten the password. So do I have any hope of getting this thing opened up? Only thing I've tried in the last 5 years has been right now. I've downloaded bitcoin core, created a wallet, shut it down, swapped out the new wallet.dat with a copy of the wallet.dat with coins trapped away in it and when I opened the btc core program back up and went to console I typed in "-salvagewallet" which gave me a "Method not found (code -32601)" error. thanks for any help. Edit: My old wallet.dat file is only 104Kb in size. I notice the newer ones are over 1000Kb. Was that normal for 2010/2011?

06/08/2019 3 min read📷216SHARES216VIEWSShare on Twitter When new Creamcoin was designed, we had in mind not only a coin that would hold parity with any cryptocurrency, but something that would demonstrate the extra-special capabilities of a decentralized ledger, capable to introduce, help and bring it further to the regular people. Blockchain developing is unstoppable complex process with endless possibilities. Integration of applications on such a technology could achieve better, secure pass of value. 0.18.0.0 On August 5th, 2019 Creamcoin code was successfully updated to the latest Bitcoin version 0.18.0 https://github.com/creamcoin/cream/ With this latest release, we proved that Creamcoin itself it’s not a sort of a tenant to the Bitcoin. Much easier to apply and to pursue the main purpose of existence and to create further innovations in our Cream Line. The new release brings tremendous performance improvements, as well as integration will be much easier for any platform, exchange or integrator. Wallets are available to Releases tab on github WALLETS
Cream Core now supports loading multiple, separate wallets. The wallets are completely separated, with individual balances, keys and received transactions. Multi-wallet is enabled by using more than one -wallet argument when starting Creamcoin, either on the command line or in the Cream config file. In Creamcoin-Qt, only the first wallet will be displayed and accessible for creating and signing transactions. GUI selectable multiple wallets will be supported in a future version. This feature will continue to be refined with later updates, as there are still some known issues in using the GUI to access the “multiwallet” command. The most notable is that you can’t use coin control features with multiple wallets loaded, or else you will likely retain the wrong wallet when attempting to switch wallets. When running Cream Core with multi-wallet, wallet-level RPC methods must specify the wallet for which they’re intended in every request. HTTP RPC requests should be send to the :/wallet// endpoint, for example 127.0.0.1:8332/wallet/wallet1.dat/. bitcoin-cli commands should be run with a -rpcwallet option, for example [bitcoin-cli -rpcwallet=wallet1.dat getbalance] A new node-level [listwallets] RPC method is added to display which wallets are currently loaded. Starting command for both wallets should look like this: [creamd -daemon -wallet=wallet1.dat -wallet=wallet2.dat]
Hardware Wallet native compatibility
With a new release of Cream Core the possibility is added in the form of use hardware wallets (Ledger, Trezor, Digital BitBox, KeepKey, Coldcard), but this process is manual and involves the use of Hardware Wallet Interaction (HWI) tool and it needs HW support and addition of Cream in the future, which is not excluded from roadmap. This is a great news for everyone who use Cream Core, and want extra security. Only applies to those who can use command line/CLI (for now), and when some of Hardware wallets actually supports Cream.
SegWit 4MB limit
SegWit replacing the block size limit with a block “weight” limit, allowing up to 4 megabytes of transaction data, and giving a substantial boost in the transaction capacity of the Cream network.
In the same with the new code update, Creamcoin Team is doing major shifting power, migrating the marketing and promotion activities, from our news site cream.technology to our main page www.creamcoin.com. We will come up with additional statement in this matter, so our supporters and followers have better perspective of Cream Line and the products of it. In the meantime we are looking into new ways that developers can enhance the capabilities of the Creamcoin protocol, integration of decentralized exchange functionality, lightning network and number of other options that would allow for different types of conditional sends of Creamcoin assets. We are inviting any individual, platform, exchange or integrator who would like to submit recommendations or feature requests, feel free to contribute to the Creamcoin Github. By Cream Team
Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything. The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years. In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.
UPDATED - Groestlcoin Core 2.18.2
This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables. NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.
How to Upgrade?
Windows If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer. OSX If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet
Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network. GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled. HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user. Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.
Simplified payment verification for fast mobile performance
Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases. This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats. To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator. VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline. If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address. VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase. VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet. If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)
Show and hide the private key with a simple toggle switch
Show full output of commands
Ability to choose between Processor (CPU) and Graphics Card (GPU) ( NVidia ONLY! )
Features both a Light and Dark Material Design-Style Themes
Free software - MIT. Anyone can audit the code.
Written in C# - The code is short, and easy to review.
Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node. It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node. Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine. Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in. Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet. Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX
UPDATED – Android Wallet 7.38.1 - Main Net + Test Net

Add confidence messages, helping users to understand the confidence state of their payments.
Handle edge case when restoring via an external app.
Count devices with a memory class of 128 MB as low ram.
Introduce dark mode on Android 10 devices.
Reduce memory usage of PIN-protected wallets.
Tapping on the app's version will reveal a checksum of the APK that was installed.
Fix issue with confirmation of transactions that empty your wallet.
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.
Is it normal for a new Full Node server to repeatedly show Potential Sale Tip detected messages? What does this even mean. I surprisingly can't find anything with a solution on the internet. Please look at my log dump and give me an idea what to do. Im trying to run a full node in service to the net

server after 24 hours and the .dat blockchain file was stuck at 16MB in size. Seemed like going nowhere.
Storage space: I am using an 8 GB microSD card for the OS, and a 128 GB USB drive for data. Minimums I would recommend: 8GB SD card and 32 GB USB drive.
Reddcoin Core client version: v22.214.171.124-a8767ba-beta (most recent version at this moment). ↳ Screenshot
You need the OS; Lubuntu. Download Lubuntu (707 MB) for the Raspberry Pi: https://ubuntu-pi-flavour-maker.org/download/. It's a .torrent download, so you will need a BitTorrent client. Message me or post in this thread if you need help with this.
You need software to write the OS to the SD card. I use Etcher. Download Etcher: https://etcher.io/.
Select image: select the lubuntu-16.04.2-desktop-armhf-raspberry-pi.img.xz file.
Select drive: select your microSD card.
Plug the SD card into your Raspberry Pi and power it up.
Lubuntu should boot up.
Set up Lubuntu, connect to the internet (wired or wireless). ↳ As username, I chose "rpi3b". You will see this username throughout this whole tutorial.
Make sure date and time are correct ([Menu] > System Tools > Time and Date). ↳ Click on Unlock to make changes. I personally change Configuration to "Keep synchronized with Internet servers". ↳ Screenshot
Reboot ([Menu] > Logout > Reboot). I am connected to wifi, but have issues getting wifi to work on initial boot. A reboot solves this issue.
Make sure system is up-to-date, install never versions.
Open LXTerminal ([Menu] > System Tools > LXTerminal). ↳ Screenshot
Enter the following in LXTerminal: sudo apt update && sudo apt upgrade ↳ Screenshot
You will be asked if you really want to continue. Enter Y (yes).
Updates are being installed! Wait until it's finished.
Install programs that will be used in this tutorial.
GParted: to partition the USB drive.
Htop: to see the amount of memory (RAM) and swap that is in use.
Enter the following in LXTerminal to install these 2 programs. sudo apt install gparted && sudo apt install htop ↳ Screenshot
Create 2 partitions on the USB drive: 1) Swap partition 2) data partition (for the Reddcoin blockchain) The swap partition is necessary: The Reddcoin wallet can be memory intensive. To prevent any crashes or freezes, add 2 GB of 'virtual' memory by creating a swap partition.
Important: Backup your USB drive if needed. The USB drive will be formatted, so the data on the USB drive will be wiped.
Please use the USB drive solely for this purpose, do not combine it with other stuff.
Keep your USB drive plugged in, do not (randomly) plug it out.
Plug your USB drive in.
GParted will be used to create the partititons. Start GParted via LXTerminal: sudo gparted ↳ Screenshot
Apply the changes. Click on the check mark or select Edit > Apply All Operations. ↳ Screenshot ↳ Screenshot
Important: The name of the swap partition is needed later, so please write it down. Mine is /dev/sda1 (first partition on first drive (drive 'a')). ↳ Screenshot
Reboot. After the reboot, the data partition you just created should be visible on your desktop. ↳ Screenshot
The swap partition is created, so now we can enable and use it.
The swap in use can be monitored with the program Htop. Open Htop ([Menu] > System Tools > Htop) to see the 'Swp' (swap) in use. ↳ Screenshot By default, swap is not used, so 0K. ↳ Screenshot You can leave Htop open.
To enable the swap partition, open LXTerminal and enter the following commands: (Assuming /dev/sda1 is your swap partition.)
Unpack the file (large file, takes around 15 minutes to unpack): sudo xz -d bootstrap.dat.xz ↳ Screenshot
After a successful unpack, your will find the file bootstrap.dat in your USB root folder. ↳ Screenshot
On the first run of the Reddcoin Core client, it will ask for a data directory to store the blockchain and wallet data.
Start the Reddcoin Core client: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
The welcome screen will appear and ask you about the data directory. I suggest a new folder on your USB drive, I picked blockchain. The directory will be created with all the necessary files. ↳ Screenshot
Click on the three dots (...) on the right. ↳ Screenshot
Click on Create Folder at the upper right corner. Type and enter in the folder name. (In my case: blockchain.) Click on Open. ↳ Screenshot ↳ Screenshot ↳ Screenshot
After selecting the directory, the Reddcoin Core client will start. Wait till it's fully loaded and close it.
Move the bootstrap.dat file to your data directory you selected in the previous step. By doing this, Reddcoin Core will use the bootstrap.dat file to import the blockchain, which speeds up syncing. sudo mv bootstrap.dat /media/rpi3b/usb/blockchain/ (Assuming blockchain as data directory.) ↳ Screenshot
The Reddcoin Core client set up is completed, but you still have to sync fully with the blockchain before you can send, receive and stake.
Keep the client running until it's fully synchronized. It will use the bootstrap file first, and download the rest of the blockchain to complete the sync. This can take some time (it took 2 days for me). Syncing the blockchain uses a lot of resources, so the software may react slow.
You can see the progress in the debug window (Help > Debug window). ↳ Screenshot
When the synchronization is completed, the red (out of sync) will disappear on the Overview screen! ↳ Screenshot
When synchronization is complete, you can start staking your Reddcoins.
You can write down your private key or copy and save it in a document. Make sure you save it somewhere only you can access it.
To import later: Debug window -> Console -> importprivkey [label] [label] is optional. ↳ Screenshot (without a label) ↳ Screenshot (with a label)
Boot with only 1 USB drive plugged in: Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly. If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
Start Reddcoin Core easier Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
Right Click on your Desktop and select Create New -> Empty File. ↳ Screenshot
Enter a file name, make sure it ends with .sh, and click on OK. I've chosen for Reddcoin.sh. ↳ Screenshot The file will be created on your Desktop. ↳ Screenshot
Add the command to start Reddcoin to the file.
Right click on the file, select Leafpad (to open the file in a text editor). ↳ Screenshot
Add the following to the file and save the file: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
To be able to execute the shell script (.sh), it has to have 'execute permissions'.
Right click on the file, and select Properties. ↳ Screenshot
Click on the Permissions tab.
For Execute, select Anyone, and click on OK. ↳ Screenshot
To start Reddcoin Core, double click on the file. A new window will pop-up, asking you what you want. Execute in Terminal is what we want, so you can click on enter. ↳ Screenshot Reddcoin Core will now start. Do not close the Terminal window, you can minimize it if needed.
Minimization options Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
Activate 'Minimize on close'. Settings -> Options... -> Window (tab) -> Minimize on close. ↳ Screenshot Reddcoin will still run when you click on the X button. To close/exit Reddcoin, right click on the Reddcoin icon in the system tray (bottom right corner). ↳ Screenshot
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
After your download is finished, open the file and click Install Package. ↳ Screenshot
To run the VNC Connect once:
Open [Menu] > Run, and enter: vncserver-x11 ↳ Screenshot
To auto run on startup:
Open Default applications for LXSession ([Menu] > Preferences > Default applications for LXSession). ↳ Screenshot
In LXSessions configuration, select Autostart in the menu left.
Under Manual autostarted applications, enter vncserver-x11 and click on + Add. ↳ Screenshot ↳ Screenshot
Reboot your Raspberry Pi and check if VNC Connect is started automatically after the reboot.
When VNC Connect is running, you'll see a VNC icon on the right bottom corner. Double click the icon to open VNC Connect and to see the IP address you need to enter to connect to your Raspberry Pi. ↳ Screenshot
