The ongoing discussion within the bitcoin-dev community revolves around the activation of Segwit in Bitcoin. There are debates and concerns raised regarding the User Activated Soft Fork (UASF) proposal for activating soft forks. One member questions the requirement for public support while not allowing members to express doubts about the UASF proposal. Concerns are raised about the effectiveness and reliability of UASF, as well as the potential for consensus bugs and the inability for nodes to identify invalid transactions.Another member expresses disappointment over public statements against UASF proposals, stating that they detract from grassroots efforts. Mark Friedenbach suggests a new proposal called "Catch-All Segwit Activation" as a potential solution to address this issue.Discussions focus on the safety and effectiveness of UASFs, with arguments made for orphaning non-compliant blocks on the flag date rather than considering the fork active on that date. Concerns about consensus bugs and the lack of communication between nodes regarding invalid transactions are also raised.The controversy surrounding BIP16 vs BIP17 is discussed, with criticisms of the inferior solution resulting from the split. The need for careful review and consideration of specific proposals is emphasized, rather than rushing to implement something quickly. The ongoing scaling debate within the Bitcoin community is mentioned, with calls for a quick resolution and the prioritization of user needs over miners.Conversations also address the technical requirements for timeout and bit assignments in BIP9. BIP148 is classified as a "user enforced miner soft-fork activation" rather than a UASF. The limitation of this approach, in terms of disruptiveness, is acknowledged.Discussions touch on the activation of SegWit and the expectations surrounding it. It is clarified that SegWit will continue to be used until a better solution comes along or interest in it diminishes. The lack of a clear definition of "the core team" is highlighted, making it difficult for outsiders to make credible proposals without contributing to the project. Caution is urged, with a reminder that changes in decentralized systems like Bitcoin cannot be expected to happen at the same speed as centralized systems.Overall, the discussions revolve around the effectiveness, safety, and controversies surrounding UASFs, BIPs, and the activation of SegWit in the Bitcoin community.Gregory Maxwell expresses reservations about the UASF approach to force Segwit activation, advocating for a patient approach instead. He suggests alternative ways to achieve the benefits of Segwit, such as removing the discount on signature data to address UTXO bloat. Despite differences in approach, most agree that Segwit will bring significant improvements to Bitcoin, including the elimination of transaction malleability and script versioning.Maxwell supports Segwit but criticizes the BIP148 UASF proposal for its disruptive nature. He believes that the forced activation of existing nodes almost guarantees disruption, while Segwit was designed to allow older unmodified miners to continue operating without interruption. Maxwell emphasizes the importance of maintaining Bitcoin's engineering standards and stability, suggesting less disruptive mechanisms and patience in activating Segwit.Discussions address the risk of non-upgraded nodes mining invalid blocks on a SegWit network. While there are concerns, it is clarified that the only real risk lies in intentionally mining on top of an invalid block, which is unlikely to happen accidentally.The conversation delves into the policy and protocol rules for mining transactions on the blockchain. It is explained that policy rules are not guaranteed to be present on all mining nodes, necessitating consensus rule enforcement to avoid chain forks.Concerns about orphaning and forking caused by the BIP148 proposal are discussed. Suggestions are made to reject only blocks containing Segwit transactions rather than rejecting all pre-Segwit transaction blocks. Various proposals for a reliable activation method are discussed, with differing opinions on the most practical approach. However, it is agreed that Segwit has undergone enough testing and it is time to activate it.There are arguments about the disruptive nature of the BIP148 UASF proposal for miners who do not upgrade. Alternative proposals aim to avoid forced disruption by allowing non-upgraded miners and nodes to continue operating as non-upgraded. The prioritization of minimizing disruption for users is emphasized, with the expectation that all miners will eventually upgrade after the initial disruption. The forced orphaning aspect of the proposal is seen as an unavoidable side-effect to make the UASF less disruptive for Bitcoin users.The author of this piece supports the implementation of segwit in Bitcoin but expresses their lack of support for the BIP148 UASF proposal. They argue that BIP148 does not meet the same engineering standards as segwit and best practices in protocol development. The main flaw with BIP148 is the forced activation of existing nodes, which may cause minor disruption.
