Introduction to BIP-110 and the New Chain
Bitcoin developers backing the BIP-110 proposal are gearing up for a new chain utilizing the BLAKE2b proof-of-work algorithm, with a tentative launch date set for September 1. This follows the previous attempt to establish a minority branch, which struggled to garner sufficient support among miners operating on the SHA-256 algorithm.
Disagreements Among Developers
The situation escalated into a disagreement on August 31, where BIP-110 advocate Loogart clashed with David Schwartz, a co-founder of Ripple and former chief technology officer at the same firm. Loogart argued that those in favor had accepted their defeat in trying to transform Bitcoin’s mainstream chain and had decided to pursue an alternative path.
“The ongoing disagreement misrepresents the situation by suggesting one faction had failed to improve the existing chain.” – David Schwartz
Schwartz emphasized the need for the discussion to remain productive and grounded, rather than painting one side as incapable. His remarks are his personal opinions and should not be interpreted as an official stance from Ripple or the XRP Ledger, as they do not play a technical role in BIP-110 or its planned chain.
Details of the BIP-110 Proposal
The initial BIP-110 proposal aimed to implement a temporary soft fork that would have limited various methods of inserting non-financial data onto the Bitcoin blockchain. These limitations were intended to lower storage needs for node operators while ensuring the primary monetary use of Bitcoin remained intact. However, critics argued that market dynamics, particularly transaction fees and node policies, should dictate block space utilization.
Following the separation of BIP-110’s enforcing branch from Bitcoin’s main network in August, it managed to create only two blocks, as the vast majority of Bitcoin miners continued to support the existing infrastructure. Reports indicated that BIP-110’s mandatory phase was entered with just 2.53% of miner backing, leaving it far behind the network maintained by major miners and exchanges.
The BLAKE2b Chain and Its Implications
The upcoming BLAKE2b chain represents not just the activation of BIP-110 on Bitcoin, but rather a distinct hard fork that incorporates a new proof-of-work mechanism alongside its own underlying asset. By substituting Bitcoin’s SHA-256d mining algorithm with BLAKE2b, the creators of this new protocol are not dependent on Bitcoin miners for security.
Although some miners may have equipment compatible with Sia’s iterations of BLAKE2b, it remains uncertain if they will invest the necessary computational resources into this new project. Ahead of the intended launch, developers arranged a testing exercise, with a successful rehearsal potentially included in the upcoming Bitcoin Knots 29.4.1 release scheduled for September 1. It’s important to note that this date is merely a goal and not a definitive deadline, with concerns about technical obstacles potentially leading to another release candidate or a rollback to the last SHA-256 block.
Concerns and Market Viability
In other developments, Luke Dashjr resigned from his position at OCEAN due to disagreements over Bitcoin mining practices and recent protocol changes, leading to OCEAN acquiring back his equity after his departure as chairman and CTO.
Ahead of the launch, no major cryptocurrency exchanges, widely-used wallets, or Lightning Network implementations have publicly expressed their support for the BLAKE2b chain, which raises concerns about how the forked assets will fare in terms of market viability and price stability.
The new network’s utilization of different BLAKE2b block headers poses additional integration challenges, meaning that existing wallets and indexing systems may not automatically recognize this chain. The issue of replay protection is also crucial; if both networks validate the same transactions, there is a risk that transactions broadcasted on one chain could be executed on the other unless users actively separate their holdings or employ preventive measures.
Conclusion
Ultimately, the impact of this breakaway network on Bitcoin will largely depend on its ability to attract miners, developers, trading platforms, and wallets post-launch. Until then, any assertions that it could supplant, rectify, or significantly endanger Bitcoin remain speculative rather than concrete outcomes.
