Groestlcoin 6th Anniversary Release
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. Ubuntu http://groestlcoin.org/forum/index.php?topic=441.0
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
The app allows you to send and receive Groestlcoin on your device using QR codes and URI links. When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.
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.
PiHole 4.2.2 on Synology Docker - setup work for me
I've setup Pihole on both Synology and Ubuntu with success (lucky me). While on Ubuntu was quite straightforward, on Synology needed some experiment. I do not activate DHCP function on my Synology; my TPLink wifi router handles it without problem. My Synology fixed IP is 192.168.2.4 (yours could be different) On Synology, thanks to this website, https://servicemax.com.au/tips/pi-hole-v4-on-synology-in-docker-the-easy-way/ which gave me 99% success. Please find below broad steps in setting Pihole version 4.2.2 (latest as at this article) on Synology DSM 6.xx docker:
search Docker registry for 'Pihole', and choose and download 'Pihole/Pihole' which is the official docker from Pihole.
Launch the Pihole image, and use the Advanced setting option to change port mapping and add some environment variables; also check autostart option
Only changes made to the default Pihole container settings:
In Port Settings tab, fixed the port mapping for container port 80, 433 to any local port number (I use 8181 and 8182, respectively). For container port 53 tcp and udp, do use 53 for both (local port number must not be duplicated with the same local port numbers being used by other Synology services)
In Environment tab, I did two things:
change ServerIP value to my Synology fixed IP (192.168.2.4 for my synology)
add variable WEBPASSWORD and give your desired admin password (to override default Pihole password automatically)
They are all the set up I did on my Synology. On main Wifi Router The other setup to do is to change default DNS servers on my main wifi router (TPLink). My ISP assigns DNS1 and DNS2 IP for my router, but the router allows me to manually change them. I changed only the DNS1 value to be my Synology fixed IP address, which is 192.168.2.4; and left the second DNS remains same. From this setup, all devices in my home will be using Pihole services automatically (filter out Ad, porn websites, bitcoin mining....). You may add more blacklist urls under Setting in Pihole admin page. --------------------------------------------------------- If you don't want Pihole to filter ad for all your devices, you don't have to change the DNS on your main router. Instead, on the device you wish to have Pihole controlled, you can change the first DNS IP to be your Synology IP, mine is 192.168.2.4 (yours could be different); and keeps the second DNS as is (mine is my main router IP which is 192.168.2.1) Once you completed the setup on both Synology and Router, log into Pihole admin page, see the statistics in Dashboard, it should display Total number of queries, queries blocked, etc... If no movement on these numbers, that means the setup was not right, you can check the Pihole container log on Synology (in DetailsLog tab). Pihole container consumes only 0.1x% of my DS411+II Atom D525 CPU, and 300+/- MB ram (from 2GB total RAM). I also run full Calibre engine and content server docker without problem on it. The Pihole on my Ubuntu will be my backup. Ports mapping: change from Auto Change ServerIP value and add variable WEBPASSWORD only Enable auto-restart Resources usage
Substratum leads Round 2 of Monthly Community Voting Round - AMA Transcript Inside!
Hey guys, If you haven’t noticed on Binance’s monthly community voting round – it has been a tight battle but Substratum has been taking the lead. I wanted to explain why Substratum has seemingly come out of no-where but has garnered some attention. Substratum is creating a solution to a very big obstacle in the world web. The below has been taken from Justin Tabb aka the Founder of Substratum and summarises what the purpose of the network is. I hope you guys can support their vision by voting for Substratum (SUB) on the https://www.binance.com/vote.html. The Substratum Network will bring the decentralized web worldwide without the need of special software for the average internet user. We will be able to serve Substratum Requests directly to the default browser (Safari, Firefox, Chrome, Internet Explorer) without any special software installed on the average consuming users computer. How Substratum Works Ease of Use: currently nearly everything that has to do with crypto or the blockchain is very difficult to use and requires technical knowledge. Through our 10+ years of experience working with companies like Apple we understand the importance of a good user experience. • The average internet user requires NO special software to use the Substratum Network. The default browser will service all requests for average users so they do not need to do ANYTHING different. Users who wish to service requests and receive SUB coins in return will have a point and click user interface that any user can setup. No technical knowledge required. SubstratumPay will be seamlessly integrated and geared towards high conversions of low technical expertise users. • Serving Up of Decentralized Content: Substratum provides a method for serving Decentralized Content (including Web Sites, Data, and Applications) through a Mac, Windows, and Linux application/service that is easy to install and run (requires no technical expertise) and serves up decentralized content using the toolkit that we have developed. This is a point and click process and requires zero technical knowledge. All the user has to do is install the application, click through a few settings and they are up and running and making Substratum Coin. Incentivizing Users to Serve the Content: in order to incentivize users to run the Substratum Network client on their machine we will be providing Substratum Coin to them for doing so. The coin is issued to the serving machine through a micro-transaction from the hosting site to the serving computer. By breaking fees down to a micro-transaction level this will greatly reduce the overall cost to companies and entities that want to host sites and applications on the internet solving yet another problem with the web as it stands today. Privacy / Security / Encryption: by allowing millions of Substratum Network users to serve content the biggest concern becomes privacy and security. Substratum solves these issues through advanced cryptography algorithms rooted in Artificial Intelligence that ensures all data remains secure. Following the lead of BitCoin this is the strength of cryptocurrency and the crypto movement. Storage and Serving of Content: in order to serve millions of sites, databases, and applications the Substratum Network employs custom developed advanced compression algorithms and machine learning to geolocate the right Substratum Network machine to serve up the content to the appropriate user based on geolocation, this will ensure the fastest load time with the lowest amount of latency and strain on the Substratum Network and both the serving and receiving machine. DNS (Domain Name System): DNS or the Domain Name System is the system that currently tells your browser where to go when you type in a domain name. For instance when you go to Chrome and type in apple.com a DNS lookup is performed to check where to send that request, the DNS system comes back with an IP address and your request is routed there. In the first version of SubstratumDNS will be a complex, AI enabled DNS server that will receive DNS requests along with the geolocation of the requestor and find based off of that information the closest available SubstratumNode that is able to fulfill the request. Development Tools for the Decentralized Web: the Substratum Network will provide an API and SDK for developing tools on the Substratum Platform. This will bring in strong developer support and will accelerate the growth of the decentralized web on the Substratum Network. Net Neutrality: with the Substratum Network ALL web-sites and applications will have EQUAL ability to be broadcast in an equal and fair manner. International Digital Barriers: currently countries like China have strict regulations on what their 1.379 billion citizens are able to interact with on the internet. Substratum will break down these barriers through a network of decentralized computers running the Substratum Network Software. Where other solutions that are currently used by residents in these countries require special software to be installed, like TOR, Substratum will take a reverse approach and require no special software for the average user. High Hosting Costs: currently businesses must pay high hosting fees to get their web-sites on the internet. Amazon Web Services launched a 3.5BIL USD per year business by attempting to solve this problem. They allow you to pay for how many minutes you run a web / database server. Substratum completely solves this problem through the power of cryptocurrency by only charging for each request that is processed. You can check out the website here: • Substratum.net o And the whitepaper is available in multiple languages inclusive of Mandarin. Furthermore, Substratum and the founders are very active in the slack – which they have recently hosted an AMA (ask me anything); I took the liberty of getting this information and if you are interested about the project to read more into it. Obviously they can’t reveal the inner workings of their product due to product sensitivity and being ahead of their competition but they are always up to date with the community through several videos on Youtube (https://www.youtube.com/channel/UCxUJoTH0XLERKl55zGnFI6g) and announcements through their social media. I recommend you follow them. Q: Any major talks with exchanges yet? A: We just announced that we are launching on our FIRST official exchange of COSS.IO on 9/30 trading against BTC and ETH. More to follow. Q: Will I be able to run a supernode? A: From the beginning NO. Supernodes will only be for Substratum; however, they will run the SAME software that are used to run a NODE. In time we will develop a requirement list to run a supernode. If you qualify you can then run a SuperNode and receive a premium payout Q: Is it possible to show a few examples of SUB payouts you get from running a node, and the tell us the ratios that affect the amount/way to calculate it somehow? (SUB owned, for how long you've been running a node etc..) Or is that still in testing? What's the difference in node rewards from someone who has 0 SUB's as opposed to someone who has X amount of SUB's? A: So the calculations for this are in process; however, you can watch our video "How Substrate Per Request Is Calculated" on our YouTube channel for an idea of what variables go into each calculation Q: How do we prevent DDoS? A: The first step is not talking about how we prevent DDoS or any other hack. We call that security through obscurity. :slightly_smiling_face: Secondly, one of the primary ways to prevent a DDoS attack is decentralization. Well that's perfect. Lastly, there are other techniques, like black-holing and basically shutting a node down. The great news is that we will be decentralized so we are only talking about a node or specific IP Address that will not disrupt the network. :thumbsup: Q: Say i got a website i want to publish on Substratum, how does this process go? A: Just a shout out if you ask for a lot of detail regarding technology stack and how exactly something will work we are most likely going to give you general answers. This is not to skirt the question. We want to be 10 steps ahead of anyone with nefarious plans before we get launched. You will be seeing more on this very soon. You should be seeing a video drop on this in the next week or two. The goal is to make this easy to use and powerful, plus empower others to use the tools. We're looking at things to different ways one is towards the average user who just want something sitting on their system and doesn't need any more details and the other is a super user who wants a lot of configuration options. Q: When more people will use Substratum and more will run nodes, the value of SUB will increase. How will it be calculated how much SUB you get as a reward for running a node as value increases? Will it be calculated by Substratum itself or will it be changed manually every so often? A: We will be calculating against the live value of Substratum Q: Is substratum detectable, for example if it’s used in a country like china and they are caught on these sites that are blocked by government… Can it be detected? A: The goal is to make it constantly moving. We do not want it to be. fast, easy, powerful, anonymous. Q: Will there be Master Nodes? A: We will have some services that are available that will help provision nodes into the network. We are still story mapping this flow and architecture. Q: Could we get more information about what you require to do to be a beta tester? A: To be a beta tester you only need to add yourself to the #beta-tester channel here in Slack. You will be notified when we are ready for you to download and install and the process and requirements to continue to run the software Q: Will you keep us informed on a at least weekly base to tell/ show us the progress made? A: Yes! We will continue to drop at least 2 professionally made update videos each week (with Jason Burns the guy who does them) and we will be doing more and more candid videos Q: Who is the winner of 10k subs and what idea did he give? And what about 2nd place and 3rd place. A: To be announced shortly. The Substrate is reserved for the payout Q: Can we mine Sub without the software? A: I will personally be selling pick-axes on my personal website "pixaxesforsale.biz" for a low cost of $19.99 Q: Unless they disclose intelligent life in space, people are still going to be mad at the end of this. A lot more will be happy though A: Haven't found intelligent life in space. Some would question finding it on earth. Q: From a legal stand point How are we protected if someone is running illegal content on our Node? A: Take a look at our video of "How Substratum Secures Your Site Content". You will never hold the entire piece of data except perhaps in memory if you are the one serving the request so you could never be culpable. Amazon isn't held responsible if I host illegal content now Q: What about content control? child porno .. and so on ... ? Is there anything to control the content or? A: Excellent question. This was a big concern for us. We do not want Substratum to become the dark web. The goal is to allow the community to self-govern, vote up and down, call out illegal activity. The utilities will allow those with bad intentions to be called out. The more we grow the better we will be about wiping out things like child porn, and just as bad human trafficking. Q: When will the raised money going to be donated? A: We have already donated $10K out and we have a pending wire for $40K going out Monday. We are working to find the BEST places with the IMMEDIATE needs. Q: When will the livestream of the burn be? A: Burn #1 will be a livestream of my computer screen later tonight. I will announce on twitter at least an hour ahead of time and we will record it so people can see it later Q: What will the final circulating supply be after all three token burns? A: We are still getting a FINAL number on this, we are still doing some FINAL Bonus sends but we will have the number VERY VERY soon and we will be posting it. We will be burning 60MIL tokens tonight so that should give you some kind of an idea. Q: can you stop slack from freezing my firefox? A: Use the downloadable app, or get better internet, or get a new computer. Sounds like a dumpster fire. Q: Everyone brings up the obvious choice of child porno that needs to be dealt with via content control. What about grayzones such as weed-selling sites? Its illegal in some countries, some not. How will Substratum deal with these grey-zones? A: Give me liberty or give me death. Q: Could i have an invite to beta test channel on slack? A: Yes, just let a moderator know. Q: could i get more information on what beta testers are required to do? I will happily be one if it helps the process and I actually manage to do it. A: Join the #beta-testers channel here Q: when will we see a new homepage? A: This is being worked on now! Q: is there a minimum amount of SUB needed to run a node? A: NO! 0 Substrate, don't worry, you will have some soon once you turn it on Q: What about running an "micronode" on any phone (there is a big % using phones all the time), I mean an app installed on phone to run a node and to host only small content like a photos... Did you think about of this? A: https://youtu.be/h6tZ_ZFuFmY Q: What if my website ethically and morally right and people downvote it out of jealousy will my website be removed if there are more number of downvotes and my content is clean? A: The process is NOT that simple, we will release more details later but this is being taken into consideration. I answered in a bit more detail above as well Q: Does the Sub team ever sleep ? A: Only when driving Q: Can I run a node on a VPS? A: I certainly won't be telling people how or where to run the node software. Do the best you can. I actually answered the VPS question above too. We will have a command line version if that is the question. That you can run on something like Ubuntu Server if you want Q: Can the voting system for all illegal stuff on the internet also be used in a 'bad' way on the regular websites to for example gain commercial/business advantages? A: It should not, no one will have 'master control' All control, so the market decides always. Q: Who will profit from cryptopay? How will this bring value to SUB tokens? A: Everyone will as we gain dominance. But also, Substratum the company will take a small percentage. This will enable us to continue building awesome apps. CryptoPay will be the cornerstone of many good things to come. Think retail, goods and services. Q: I work at a games company with 200+ high powered pcs. If I install sub nodes on every single one of them at night, will IT be able to catch and fire me A: See your HR manual, or HR supervisor for those questions. Q: How do websites and hosters remain protected from hacking, if sites are created with innate vulnerabilities does that expose other sites hosted by the same node? A: This is a great question. Hosting Nodes will have to vet out their security. Again, being decentralized goes a long way in providing security. So does encryption. We will help hosts be the best hosts possible. Q: Please explain the earning in SUB by running a node? A: So the SUB comes FROM the HOST (who purchases the SUB) to the NODE for the cost of the transaction. https://youtu.be/LWZ1DIGGOoQ Q: When will the tokens be sent for the 100 Sub giveaway A: Shortly Q: How will Substratum market themselves towards countries that needs SUB the most but are hard to reach, such as North Korea, Africa, China? A: Think spider web. The more that join, and use, the less it can be controlled. Q: How long will this bear market last for? A: Let me put the fortune teller hat on. Crypto is a young demographic currently. It will be bear'ish until we make the technology easier and they get older.
