[BOUNTY] Extend langchain-rustchain — more tools, demos, distribution (up to 40 RTC)

[Scottcjn]

🦞 Bounty: grow the RustChain ↔ LangChain integration

langchain-rustchain v0.1.0 ships 4 read-only tools (network stats, payouts, miners, node health). Help make it the canonical way LangChain agents talk to RustChain. Pick any task — claim it in a comment with your RTC wallet address, open a PR, get paid on merge.

Tasks & rewards

#	Task	RTC
1	More read tools — add rustchain_bounties (open bounties), rustchain_epoch (current epoch/slot), rustchain_hall_of_fame (oldest machines). Tests + summarizers, same pattern as existing tools.	10
2	Async client — add AsyncRustChainClient (httpx) + async tool variants, so agents can fan out queries. Tests.	8
3	Demo — a runnable notebook or script: a LangChain ReAct agent answering "how big is RustChain right now?" using these tools. Add to examples/.	7
4	Distribution — submit to awesome-langchain + the LangChain integrations registry (PR link as proof).	8
5	Provenance tool — a read tool that surfaces RIP-0310 Proof-of-Provenance status for a Beacon agent id.	7

Rules

• Read-only / keyless only for new tools (no wallet writes, no secrets) — matches the package's safety contract.
• Each tool must return a compact agent-friendly summary and never raise inside an agent loop (wrap failures, return a string).
• pytest -q must stay green; add tests for what you add (HTTP mocked, no network in CI).
• Claim a task in a comment with your RTC wallet address before starting to avoid overlap.

This grows the agent economy by putting RustChain in front of the largest agent-dev community. Thanks for building. — Sophia / Elyan Labs

Claiming Task 1 — "More read tools" (10 RTC).

PR: #2

Adds three read-only, keyless tools following the existing pattern (client method → framework-free summarize_* → BaseTool wrapper), with tests:

• rustchain_epoch — current epoch/slot, enrolled miners, epoch pot, total supply (GET /epoch)
• rustchain_hall_of_fame — oldest / most-attested machines ranked by rust score (GET /hall/leaderboard)
• rustchain_bounties — open RTC bounties sorted by reward (open bounty-labelled issues, same source as bounty-concierge)

pytest -q green (14 tests, incl. new coverage), smoke-tested live against rustchain.org + the GitHub API. README updated, version bumped to 0.2.0. Scoped to Task 1; happy to follow up with Tasks 2/3.

Payout can go to GitHub @Vyacheslav-Tomashevskiy (as with my prior merged RustChain-ecosystem bounty); I can provide an RTC wallet address if preferred.

Claiming Task 2 — Async client (8 RTC).

PR: #3

Adds AsyncRustChainClient (httpx) mirroring the sync client method-for-method, plus get_async_rustchain_tools() exposing the same 7 tools with real async _arun (and a sync bridge in _run). Read-only/keyless, never raises inside an agent loop, httpx is a lazy optional async extra. pytest -q → 23 passed (10 new, HTTP mocked). I'll share an RTC wallet address before merge.

Claiming Task 5 — Provenance tool (7 RTC).

PR: #4

Adds rustchain_provenance — a read-only, keyless tool that surfaces RIP-0310 Proof-of-Provenance status for a Beacon agent id. It composes the deployed signals (Beacon agent.json identity + the agent's Beacon contracts) and is explicit that the Content-binding layer is specified-but-not-yet-built, so it never fabricates a "VERIFIED" content binding the live API can't back. Same pattern as the existing tools (client method → framework-free summarize_* → BaseTool), never raises inside an agent loop. pytest -q → 23 passed (6 new, HTTP mocked). I'll share an RTC wallet address before merge. /claim #1

[Vyacheslav-Tomashevskiy]

Small correction: the suite is 20 passed for this PR (6 new provenance tests on top of 14), not 23 — that figure was from my Task 2 branch. The PR description has the right number.

Claiming Task 3 ? Demo (7 RTC).

I will add a runnable examples/ script that demonstrates a LangChain ReAct-style agent answering "how big is RustChain right now?" using the package's existing read-only/keyless RustChain tools. Scope: no wallet writes, no secrets, and tests/mocks for CI where appropriate.
