From 94a27c9638f7ad19743abc48396c0d69014285f9 Mon Sep 17 00:00:00 2001 From: "Loki (AI Agent)" Date: Wed, 4 Feb 2026 04:44:55 +0000 Subject: [PATCH] feat: implement issue attestations (Issue #19) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit πŸ€– Authored by Loki Adds support for on-chain attestations of GitHub issues, enabling reputation building for non-code contributions (bug reports, feature requests, triage). Schema: - New schema on Base Sepolia for issue attestations - UID: 0x56dcaaecb00e7841a4271d792e4e6a724782b880441adfa159aa06fa1cfda9cc - Fields: repo, issueNumber, author, title, labels, timestamp, identityUid Backend: - Added issue-fetching functions to backend/src/github.ts - Created issue-constants.ts with schema UID and encoding helpers - Created register-issue-schema.ts for schema registration Scripts: - Created scripts/attest-issue.mjs for manual issue attestation - Tested with issue #19 itself Documentation: - Created docs/schemas/ISSUE.md with full schema documentation - Includes examples, verification strategy, and querying Demo: - Issue #19 attested on-chain - TX: 0x274029cc607e52200cec365318968f6eeb09cbb32ce46f6c5f0e688cd993a92c - Attestation: 0x0000000000000000000000007a1de0fa7242194bba84e915f39bf7e621b50d2e Closes #19 --- ISSUE_ATTESTATIONS_PLAN.md | 275 ++++++++++++++++++++ backend/src/github.ts | 102 ++++++++ backend/src/issue-constants.ts | 40 +++ backend/src/register-issue-schema.ts | 80 ++++++ docs/schemas/ISSUE.md | 196 ++++++++++++++ scripts/attest-contribution.mjs | 141 ++++++++++ scripts/attest-issue.mjs | 226 ++++++++++++++++ scripts/create-contribution-attestation.mjs | 114 ++++++++ 8 files changed, 1174 insertions(+) create mode 100644 ISSUE_ATTESTATIONS_PLAN.md create mode 100644 backend/src/issue-constants.ts create mode 100644 backend/src/register-issue-schema.ts create mode 100644 docs/schemas/ISSUE.md create mode 100755 scripts/attest-contribution.mjs create mode 100755 scripts/attest-issue.mjs create mode 100755 scripts/create-contribution-attestation.mjs diff --git a/ISSUE_ATTESTATIONS_PLAN.md b/ISSUE_ATTESTATIONS_PLAN.md new file mode 100644 index 0000000..aaa1585 --- /dev/null +++ b/ISSUE_ATTESTATIONS_PLAN.md @@ -0,0 +1,275 @@ +# Implementation Plan: Issue Attestations (GitHub Issue #19) + +## Executive Summary + +This plan outlines the implementation of issue attestations for didgit.dev, enabling users to track non-code contributions (bug reports, feature requests, issue triage) on-chain alongside commit attestations. + +--- + +## 1.
