From 4894bcc4eb6ef852fa9a80ee8f196def6e2ee428 Mon Sep 17 00:00:00 2001 From: Murch Date: Wed, 20 May 2026 15:13:55 -0700 Subject: [PATCH] bip52: Update to Closed This proposal appears abandoned, as it has not had any updates in over four years, and cursory search did not produce any public discussions of it since it was published either. Attempts to contact the authors did not receive a response within four weeks. --- README.mediawiki | 4 ++-- bip-0052.mediawiki | 10 ++++++---- 2 files changed, 8 insertions(+), 6 deletions(-) diff --git a/README.mediawiki b/README.mediawiki index 5c86ed0..bada5e2 100644 --- a/README.mediawiki +++ b/README.mediawiki @@ -302,13 +302,13 @@ users (see also: [https://en.bitcoin.it/wiki/Economic_majority economic majority | Gavin Andresen | Informational | Deployed -|- +|- style="background-color: #ffcfcf" | [[bip-0052.mediawiki|52]] | Consensus (hard fork) | Durable, Low Energy Bitcoin PoW | Michael Dubrovsky, Bogdan Penkovsky | Specification -| Draft +| Closed |- | [[bip-0053.mediawiki|53]] | Consensus (soft fork) diff --git a/bip-0052.mediawiki b/bip-0052.mediawiki index 72b2823..d59b6cb 100644 --- a/bip-0052.mediawiki +++ b/bip-0052.mediawiki @@ -4,7 +4,7 @@ Title: Durable, Low Energy Bitcoin PoW Authors: Michael Dubrovsky Bogdan Penkovsky - Status: Draft + Status: Closed Type: Specification Assigned: 2021-05-13 License: BSD-2-Clause OR OPUBL-1.0 @@ -284,13 +284,15 @@ With significant progress in optical and analog matrix-vector-multiplication chi PoWx will also be publishing the designs of the current optical miner prototypes in the near term under an open-source hardware license. +== Changelog == + +* 2026-06-18: +** Updated to Closed after the proposal has not made progress for several years and [https://groups.google.com/g/bitcoindev/c/Vrh7oED9b9Q/m/TrCEKRjNAAAJ attempts to contact the authors] did not succeed. + == Acknowledgments == We thank all the members of the Bitcoin community who have already given us feedback over the last several years as well as others in the optical computing community and beyond that have given their input. - - - [1] M.
