Why Technical Changes Alone Don’t Warrant a Fork
The former chief technology officer of Ripple has stated that the failure to pass BIP-110 does not warrant the creation of a new blockchain, emphasizing that consensus disagreements should not lead to chain splits. His comments come amid discussions about a proposed alternative chain that has already replaced Bitcoin’s SHA256d mining algorithm with BLAKE2b under its own hard-fork rules. The remarks were made in a public interview where he criticized the motivation behind launching a new network based solely on a failed Bitcoin Improvement Proposal vote.

Bitcoin Shows Early Bullish Signs Despite Struggle to Surpass $84,000The new chain in question has adopted BLAKE2b as its proof-of-work function, moving away from the SHA256d algorithm that secures Bitcoin. This change was implemented as part of its hard-fork parameters, aiming to differentiate its mining ecosystem and resist ASIC dominance. However, the Ripple CTO emeritus argued that such technical shifts do not justify a chain split, especially when rooted in governance disagreements rather than fundamental flaws in the original protocol. He stressed that Bitcoin’s strength lies in its social consensus, and that losing a vote should not be grounds for fragmentation.
What Happens When Governance Disputes Lead to Splits?
He explained that while algorithmic changes like switching to BLAKE2b can have merit, they must be evaluated within the broader context of network security and miner incentives. Altering the mining function affects hardware compatibility and could centralize mining power if not carefully designed. The former Ripple executive noted that many proposed improvements can be tested on sidechains or layer-two solutions without endangering the main chain’s stability. He warned that frequent forks over vote outcomes risk undermining Bitcoin’s credibility as a neutral, predictable system.
When asked whether such actions set a dangerous precedent, he replied that repeated splits based on political disagreements could erode user trust and fragment liquidity across chains. He pointed out that Bitcoin’s value derives partly from its immutability and predictable supply, both of which are weakened when the chain divides over non-technical disputes. Instead of forking, he advocated for deeper dialogue within the Bitcoin development community to resolve disagreements through compromise rather than code divergence.
What is BIP-110 and why did it fail to pass? BIP-110 was a proposal to increase Bitcoin’s block size limit to 2MB with a goal of improving transaction capacity. It failed to gain sufficient miner and node support during the voting process, falling short of the consensus threshold required for activation.
Frequently Asked Questions
Why did the new chain choose BLAKE2b over SHA256d? The new chain adopted BLAKE2b to differentiate its mining algorithm, potentially reducing ASIC advantage and encouraging broader participation in block validation through more accessible hardware.
Does changing the mining algorithm require a hard fork? Yes, replacing SHA256d with BLAKE2b requires a hard fork because it changes the consensus rules that determine valid blocks, making the new chain incompatible with the original Bitcoin network without a software update.
