⛓️ Consensus / Hard Fork — activates at block height 350,000
This release contains consensus-breaking changes that activate via hard fork at block height 350,000.
All node operators, miners, and exchanges must upgrade before block 350,000 to remain on the correct chain. Nodes running older versions will fork off the network at the activation height.
The fork bundles a set of mining and header-validation fixes, including a critical RandomX (RxM) vulnerability, C29 mining verification, RandomX-Tari (RxT) header mutability, and a RandomX engine upgrade — see the consensus items in What's Changed below.
