On September 8, 2014, Pieter Wuille made changes to the Bitcoin Improvement Proposal (BIP) repository, specifically altering the order of rules and adding reference documentation. He later sent another pull request on September 12, 2014, focusing on compressed or uncompressed public keys. During discussions with Gregory Maxwell, concerns were raised about the lack of specificity in rule 4 of BIP 62. Wuille agreed to address this issue by making updates to the text. The conversation also touched upon additional consensus rules and their limitations. In response, Wuille sent a new pull request for BIP 62, clarifying the limitations of the rules and reordering them.In another discussion about BIP 62, Gregory Maxwell expressed concerns about the lack of specificity in rule 4. Wuille acknowledged the issue and planned to make necessary changes. They also discussed the reordering of rules and the presence of inherently malleable scriptPubkeys. During a conversation about cryptographic protocols, Gregory Maxwell explained the properties of the DSA nonce and why duplicating the verifier's generation of k is impossible. He emphasized that attackers are not bound by protocols unless prevented and that proving a specific nonce generation scheme without revealing the private key is unreasonable. In a discussion about BIP 62, Mike Hearn questioned the necessity of rule 4. Wladimir explained that non-push operations in scriptSig can lead to malleability, which the rule aims to prevent. Aaron Voisine and Gregory Maxwell debated the effectiveness of deterministic signing and randomness-free signature systems in relation to the DSA nonce and its implications for Bitcoin transactions.Pieter Wuille sent a pull request to modify BIP 62, making two new rules mandatory for old-style transactions. He explained the rationale behind this change and stressed the importance of strict DER compliance for signatures. In a separate conversation, Wuille discussed the absence of non-DER signatures in recent blocks with an unidentified individual.Mike Hearn and Pieter discussed potential changes to Bitcoin's consensus rules, including the necessity of rule 4 and the significance of backwards compatibility. The author of the context questioned the reasoning behind rule 4 and expressed a preference for preserving compatibility until older versions are phased out. Wuille subsequently sent a pull request to modify BIP 62, removing the requirement for bug-for-bug compatibility with OpenSSL and suggesting investigating non-DER signatures in blocks before making any changes.Furthermore, Pieter Wuille, a Bitcoin Core developer, has proposed a change to the Bitcoin protocol to support Discrete Log Contracts (DLCs) on the network. DLCs are smart contracts that enable trustless, non-custodial financial agreements between parties. The proposed change introduces a new opcode, OP_DLC, which would facilitate the execution of DLCs without altering the underlying Bitcoin infrastructure. The suggested modifications also enhance the Bitcoin scripting language, enabling complex contract logic.To ensure successful implementation, Wuille is actively seeking comments and feedback from the Bitcoin community. He has shared a draft of the proposed changes on the Bitcoin development mailing list, inviting developers and stakeholders to review and provide input. By incorporating DLCs into the Bitcoin protocol, Wuille believes it will expand the possibilities of decentralized finance and smart contract applications on the network. This includes prediction markets where users can bet on real-world events and decentralized derivatives trading without centralized intermediaries. Overall, the proposal aims to enhance the functionality and versatility of the Bitcoin network through the introduction of support for Discrete Log Contracts.
