Staking Rewards

A block policy is added that 10% of the block reward is allocated as a staking reward. There is one recipient in each block, chosen from the avalanche quorum. The reward is sent to the Proof `payoutAddress` field, chosen deterministically from the quorum based on the previous block hash, with probability weighted by the Proof's stake amount.

eCash miners must ensure that their mining setup is properly configured to add the staking rewards to the coinbase outputs. The payout address and amount are available via the `getblocktemplate` RPC.

Miner fund increase

The miner fund, part of the block reward that is funding eCash network development, was increased from 8% of the block reward to 32%.

eCash miners must ensure that their mining setup is properly configured to use the proper miner fund amount. This information is available via the `getblocktemplate` RPC.

The process of upgrading your node is straightforward: simply stop the currently running node, download the new version, and start the new version. Here are some example instructions for upgrading from version 0.27.15 to version 0.28.4 on Linux:

  1. Shut down the node:
    ./bitcoin-abc-0.27.15/bin/bitcoin-cli stop
  2. Download the new version archive from the website:
    wget https://download.bitcoinabc.org/0.28.4/linux/bitcoin-abc-0.28.4-x86_64-linux-gnu.tar.gz
  3. Extract the archive:
    tar xzf bitcoin-abc-0.28.4-x86_64-linux-gnu.tar.gz
  4. Restart the node with the new version:
    ./bitcoin-abc-0.28.4/bin/bitcoind -daemon
  5. Clean up old version and archives (optional):
    • rm -rf bitcoin-abc-0.27.15
    • rm -f bitcoin-abc-0.27.15-x86_64-linux-gnu.tar.gz
    • rm -f bitcoin-abc-0.28.4-x86_64-linux-gnu.tar.gz
