374 - Discrete Log Equality Proofs
BIP: 374 source Layer: Applications Title: Discrete Log Equality Proofs Authors: Andrew Toth Ruben Somsen Sebastian Falbesoner Status: Draft Type: Specification Assigned: 2024-12-26 License: BSD-2-Clause Discussion: https://gist.github.com/andrewtoth/df97c3260cc8d12f09d3855ee61322ea https://groups.google.com/g/bitcoindev/c/MezoKV5md7s Version: 0.2.0 Table of ContentsIntroductionAbstractCopyrightMotivationSpecificationDescriptionDLEQ Proof GenerationDLEQ Proof VerificationBackwards CompatibilityTest Vectors and Reference CodeChangelogFootnotesAcknowledgements Introduction Abstract This document proposes a standard for 64-byte zero-knowledge discrete logarithm equality proofs (DLEQ proofs) over an elliptic curve. For given elliptic curve points A, B, C, G, and a scalar a known only to the prover where A = a⋅G and C = a⋅B, the prover proves knowledge of a without revealing anything about a. This can, for instance, be useful in EC...

3 - Updated BIP Process
BIP: 3 source Title: Updated BIP Process Authors: Murch Status: Deployed Type: Process Assigned: 2025-01-09 License: BSD-2-Clause Discussion: https://github.com/murchandamus/bips/pull/2 https://gnusha.org/pi/bitcoindev/59fa94cea6f70e02b1ce0da07ae230670730171c.camel@timruffing.de/#t Version: 1.4.0 Requires: 123 Replaces: 2 Abstract This Bitcoin Improvement Proposal (BIP) provides information about the preparation of BIPs and policies relating to the publication of BIPs. It replaces BIP 2 with a streamlined process, and may be amended to address the evolving needs of the BIP process. Motivation BIP 2 was written in 2016. This BIP revisits aspects of the BIP 2 process that did not achieve broad adoption, reduces the judgment calls assigned to the BIP Editor role, delineates the BIP types more clearly, and generalizes the BIP process to fit the community’s use of the repository. Fundamentals What is a BIP? BIPs are improvement proposals for Bitcoin. The ma...
