What happened?

The planned upgrade of the eCash network has successfully been completed. The first post-upgrade block is block number 871168.

Who needs to upgrade?

All operators of a Bitcoin ABC full node must upgrade to the latest major version (0.30.7). This includes node operators, Avalanche staking nodes, Miners and Exchanges. The up-to-date node version is available at our Releases page.

What features are included in the Network Upgrade?

The Heartbeat feature, also known as Real Time Targeting, activated with this upgrade. This is a block policy that makes it more difficult to mine blocks faster than the expected 10 minutes average, preventing large bumps in difficulty that can lead to inconsistent block intervals.

Miners need to update their setup according to the instructions on the eCash Mining page.

How do I upgrade?

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 0.29.13 to the latest version (0.30.7) on Linux:

• Shut down the node: ./bitcoin-abc-0.29.13/bin/bitcoin-cli stop
• Download the new version archive from the website: wget https://download.bitcoinabc.org/0.30.7/linux/bitcoin-abc-0.30.7-x86_64-linux-gnu.tar.gz
• Extract the archive: tar xzf bitcoin-abc-0.30.7-x86_64-linux-gnu.tar.gz
• Restart the node with the new version: ./bitcoin-abc-0.30.7/bin/bitcoind -daemon
• Clean up old version and archives (optional):
  • rm -rf bitcoin-abc-0.29.13
  • rm -f bitcoin-abc-0.29.13-x86_64-linux-gnu.tar.gz
  • rm -f bitcoin-abc-0.30.7-x86_64-linux-gnu.tar.gz

Do I need to upgrade my wallet?

The network upgrade only affects full nodes. Other eCash software, including wallets such as Electrum ABC are not affected by the network upgrade.
