[Wallet] Official Release - Reddcoin Core v2.0.0

  • Reddcoin Core 2.0.0

    Version 2.0.0 is the official release version of Reddcoin Core. On top of the new features, this update contains very important security fixes and all users MUST upgrade to this version as soon as possible. Details on several vulnerabilities were made public by the Bitcoin team (Official Bitcoin warning) regarding the issues. It is particularly important that users who are staking do upgrade, as once BIP 66 is enforced, version 3 blocks will be rejected from the network entirely.

    Reddcoin 2.0.0 is a complete rebuild based off Bitcoin 0.9. This means in terms of the code-base we introduced all the changes up to Bitcoin 0.9.5 into this version of Reddcoin Core.

    We have also included a couple of features from the 0.10 build including a connected peers tab and bandwidth monitoring

    We therefore suggest to read the release notes of Bitcoin up to and including 0.9.

    v2.0.0 is a recommended update for all users.

    Notable changes

    For further explanation of these, see the above mentioned Bitcoin release notes.

    Code-base switched to Bitcoin

    In efforts to improve the fast adoption of upstream changes, Reddcoin was switched from using litecoin to bitcoin code base.

    New utility applications

    Reddcoin-cli for RPC command line functionality. Moving to split the client and server components from reddcoind

    Faster synchronization

    Reddcoin Core 2.0.0 includes parallel block synchronization to greatly reduce the initial blockchain synchronization time.

    Strict signature encoding (BIP66)

    This release activates BIP66 which enforces strict rules about how transaction signatures are encoded and therefore will introduce a new block version (4). These rules will only activate once a certain number of blocks are mined with this new version. It will take effect after 85% of the network (6120/7200 blocks) are generating v4 blocks (7200 blocks is equivilant to 5 days worth of blocks).

    NOTE: This is not a hard fork, as all existing wallets will accept version 4 blocks, although they'll fail to enforce the new requirements.


    Once the above rule is activated, the network will reject the creation of version (3) blocks (stakes on earlier clients e.g v1.4.1). Transactions using earlier clients will be accepted by the network

    RPC access changes

    RPC access now supports binary network addresses. This means that you can specify a single IP address, a CIDR network address or a netmask for accessing the RPC service. Please note, wildcard string matching no longer works and will display an error in the debug.log file when you attempt to use use a wildcard string in the rpcallowip= variable, either as a config setting or launch parameter.

    Before After
    rpcallowip= rpcallowip=
    rpcallowip=10.0.0.* rpcallowip=
    rpcallowip=10.0.* rpcallowip=
    rpcallowip=* rpcallowip=::/0
    rpcallowip=192.168.1.* rpcallowip=

    Note: IPv6 addresses can also be used.

    Stakeminer will wait for both the blockchain and network

    This release will allow the staking of wallets that are not encrypted. Previously, if a wallet was not encrypted, the wallet would attempt to stake blocks as they were being downloaded. The wallet will now wait before staking is enabled.

    It is however highly recommended to encrypt your wallet for your own peace of mind.

    QT Debug window includes network and peer details

    An addition to the QT wallet is the network graph tab to visually monitor network usage and the peers details tab to display other attached nodes.

    DNS Seeds added

    Additional dns seeds (dnsseed.redd.ink/testnet-dnsseed.redd.ink) for main and testnet to create some resilience for the network discovery

    General comments

    Please backup your wallet regularly and especially before performing this upgrade. Do not copy your wallet.dat while Reddcoin Core is open. Instead you should either use the backup feature you find in the "File" menu or shut down Reddcoin Core completely before you make a copy of your wallet.dat.

    o Upgrade

    First, make a copy (backup) of your existing wallet.dat and data folder

    Where to find your Reddcoin data folder?

    1. Windows: C:\Users\USER NAME\AppData\Roaming\Reddcoin
    2. Mac: /Users/USER NAME/Library/Application Support/Reddcoin
    3. Linux:~/.reddcoin

    Install Reddcoin Core software

    1. Uninstall your old wallet
    2. Install your new wallet

    If you follow this procedure, we should be able to help you further if the need arises.

    The new wallet is compatible with the old blockchain files. There is no need to re-sync from the start.
