Groestlcoin 22nd December Release

Groestlcoin Release December 2022

Unfortunately, this year has been another rollercoaster for the world of Crypto and GRS. With the delisting of GRS from Binance earlier this year causing heartbreak to many, fortunately, the price was relatively unaffected on all remaining exchanges.
The collapse of FTX in November sent shockwaves through the crypto-sphere with losses totalling over $1BN USD and some individuals losing tens of thousands of dollars worth. Whilst this is devasting, this reinforces the mantra of "not your keys, not your coins", and will hopefully allow for greater transparency from exchanges in the future.
From everyone in the Groestlcoin team, we hope you have a fantastic Christmas / Holiday and here's to a prosperous 2023!

 

What’s Being Released Today?

 

GROESTLCOIN DEVELOPMENT RELEASE

Groestlcoin Core 24.0.1

C-lightning 22.11.1

What am I?

C-Lightning is a specification-compliant Lightning Network implementation built in C. It is a lightweight, highly customisable and standard compliant implementation of the Lightning Network protocol. C-Lightning only works on Linux and Mac OS and requires a local or remote instance of Groestlcoind (version 2.16 or above) that is fully synced to the correct blockchain.

Changelog 22.11.1

  • The new experimental reckless plugin manager can be used to download, install and uninstall plugins on the fly. We have many new features planned for it, so stay tuned.
  •  When receiving a keysend any extra TLV fields will be stored so they can be retrieved later.
  •  The --database-update=false flag allows users wanting to test unreleased versions from accidentally upgrading the database, and then be unable to switch to a released version again.
  •  Several performance issues, particularly for larger nodes, have been addressed.
  •  Support for the legacy onion encoding has been removed, since the more modern and flexible TLV encoding is now widely deployed.
  •  We have started preparing for a splicing implementation, but merging the interactive TX creation API.
  •  We now require all channel_update messages include htlc_maximum_msat (as per latest BOLTs)
  •  Results from the API can now be filtered using the filter API. This can be used to massively reduce the size of results if only part of it is required.
  •  The openchannel hook can be used to set a reserve value other than the 1% default value. This also allows not having a reserve in case the peer is (semi-)trusted.
  •  We reintroduced a number of deprecated features, since some integrations had missed the deprecation window, and asked for some more time to update their apps.
  •  We delayed the rollout of DNS names in the gossip due to a lack of support in the network.

Features

  • Ability to create new channels
  • Ability to close existing channels
  • Completely manage all channel states, including exceptional ones
  • Performing path-finding within the network, passively forwarding incoming payments
  • Sending outgoing onion-encrypted payments through the network
  • Automatic channel management (auto-pilot)

Grsd

What am I?

GRSD is an alternative full-node Groestlcoin implementation written in Go (GOLang). If you want an alternative full-node wallet and are an advanced user, then GRSD is the right choice for you. The wallet will also properly relay newly mined blocks, maintains a transaction pool and relays individual transactions that have not yet made it into a block. It ensures all individual transactions admitted to the pool follow the rules required by the blockchain and also includes more strict checks which filter transactions based on miner requirements (“standard” transactions).
