The Bitcoin network experienced a chain split overnight following the activation of the controversial BIP-110 upgrade, though the enforcing branch has effectively stalled after mining only two blocks due to a pronounced lack of miner support. The division occurred as the proposal's mandatory signaling period commenced, revealing a significant gap between the upgrade's technical requirements and the actual hashpower backing it across the distributed mining landscape.
According to CryptoSlate, none of the first 59 blocks on the dominant chain signaled support for the proposal, indicating a silent boycott by mining participants. The enforcing branch managed to mine one successor block before halting entirely, leaving the alternative chain stranded after producing only two blocks total. This development suggests that the envisioned upgrade path has encountered insurmountable resistance from the network's mining constituency, rendering the proposed changes effectively inert.
The technical mechanism underlying the split involves mandatory signaling requirements that proceed with minimal hashpower support. As reported by Cointelegraph, the enforcing fork remains stuck at Bitcoin's full mining difficulty, creating a prohibitive barrier for the minority chain to achieve consistent block production. Without sufficient computational power directed toward the BIP-110 branch, the network cannot maintain the block generation schedule necessary for functional operation, resulting in an existential operational crisis for the enforcing variant.
The stalling of the enforcing branch represents a de facto failure of the upgrade proposal to achieve network consensus. While the chain split technically succeeded in creating two distinct versions of the Bitcoin ledger, the inability of the enforcing branch to progress beyond two blocks demonstrates the practical impossibility of implementing protocol changes without miner cooperation. The situation highlights the decentralized governance structure inherent to Bitcoin, where economic and computational stakeholders ultimately determine the trajectory of protocol development through their participation or refusal to signal support for specific improvements.
Currently, the dominant chain continues to operate without adopting the BIP-110 changes, while the enforcing branch remains frozen at the current difficulty adjustment level. This configuration leaves the upgrade in a state of suspended animation, unable to generate new blocks or process transactions in a timely manner. The lack of hashpower commitment effectively renders the enforcing chain inoperable for practical purposes, reinforcing the original chain's position as the canonical version of the Bitcoin network while demonstrating the significant barriers facing any protocol alteration that fails to secure majority miner backing.
