Adam Back, CEO and co-founder of Blockstream, explains that once a 110 signaling block is mined following the fork height, bitcoin miners will fork off from that chain. He adds that this process could take about a day to happen.
Back notes miners are unlikely to continue mining on the 110 block chain once it falls behind, following the longest chain rule that prioritizes the chain with the most work. Others in the network would likely discard blocks from the lagging chain.
Back recently clarified that recent bitcoin updates address bugs misunderstood by newcomers, rather than fundamental network limitations, in comments on protocol changes. He has also detailed bitcoin's technical underpinnings using the E=mc² analogy, discussing the nonce, hashchain, and halving in a separate explanation. These insights reflect his ongoing efforts to elaborate on bitcoin’s mechanics and recent network behavior.
