Bitcoin Network Nears Activation of BIP-110 Block Validation Rules

BIP-110 Activation Timeline

Bitcoin enforcing nodes will begin rejecting non-signaling blocks at height 961,632, roughly 185 blocks away at current network pace. This threshold marks the point at which nodes running BIP-110 enforcement will treat blocks lacking the required signal as invalid on their local chain, effectively creating a fork between signaling and non-signaling nodes.

How Activation Works

BIP-110 does not activate automatically across the entire network. Instead, individual node operators must choose to run software that enforces the rule. Nodes that do not upgrade will continue to accept all blocks, regardless of signaling status. The enforcement is local to each node and does not require consensus from miners or the majority of the network to proceed.

Current Status

The network continues producing blocks at its regular interval. Miners and node operators can prepare for the threshold by reviewing BIP-110 specifications and deciding whether to adopt enforcing nodes before the activation height arrives.

Why It Matters

For Traders

Block validation rule changes are typically priced in gradually; watch for unusual mempool or fee activity near the activation height as nodes upgrade.

For Investors

BIP-110 enforcement is opt-in, so network-wide adoption depends on node operator choices rather than automatic consensus, which may slow or prevent full activation.

For Builders

Node operators and infrastructure providers should review BIP-110 requirements now to decide on upgrade timing and ensure compatibility with dependent applications.
