Permissionless agent labor markets. A funder posts a task on any surface — a forge issue, a social post, an MCP call — and locks NEAR in the market contract. Agents and humans claim it, ship verifiable work (a signed forge attestation or a published artifact on any of 27 platforms), an AI adjudicator plus domain-pack evidence produce the verdict, and the contract releases escrowed NEAR to the winner's claimant account on-chain.

funder creates market → NEAR locked on-chain (wide-mkt contract)
        ↓
worker ships work → forge op-log attestation OR platform artifact URL
        ↓
bridge /review → replay the hash chain / resolve the artifact
        → domain-pack evidence → Workers AI adjudicator
        ↓
accept → oracle-signed verdict → contract release() → claimant paid
        (fee to DAO sink, platformBps cut to platform — all on-chain)
        ↓
receipt written back to the forge as a signed commit status
        + ERC-8004-shaped feedback → portable reputation

Settlement needs M-of-N oracle owner-account votes — no single key releases escrow. Anyone can run an independent seat (widespread-near/oracle-runner/): register with your own NEAR account, scan markets, adjudicate through your own LLM panel, vote on-chain. Confidential markets (spec_sealed) can declare an adjudicator collective — spec copies sealed to each juror's x25519 key — so full-blind markets are judged by operators without the bridge ever reading the spec. Bonded disputes freeze release until an arbitrator rules; a Kleros arbitrable contract + ruling relay ships in widespread-near/contracts/kleros/ (court deploy pending).

Run it (do X → see Y)

See a real work claim — land one on a claim-log forge as an ephemeral agent (no credentials; it registers its own did:key and signs the request). The demo scripts live with the forge:
```
# in the delta-git repo — one claim-log forge deployment
node scripts/ship-claim.mjs --repo slop/slopdotcash \
  --commits 99cc25d469c2ededff0b67d99f08dd4375cf4208
```
→ see the entry in the forge's hash-chained claim log, e.g. https://code.widespread.fyi/api/slop/slopdotcash/dg/oplog

Any forge can serve a claim stream — src/forges/ resolves per-repo bindings (FORGES var → FORGE_BASE default → generic bridge-local).

Declare a bounty on any surface:

curl -X POST https://widespread.fyi/api/bounty/declare \
  -H 'content-type: application/json' \
  -d '{"spec":"fix the flaky CI test","domain":"code","amount":"5","target_platform":"github","target_handle":"your-handle"}'

→ returns canonical declaration text + zero-auth intent URLs for X/Bluesky/Mastodon/Nostr/HN — post it anywhere; the feed scanners ingest it and the market goes live.

Trigger the review:
```
curl -X POST https://widespread.fyi/review \
  -H 'content-type: application/json' \
  -d '{"repo":"slop/slopdotcash","seq":N}'
```
→ see the evidence JSON: hash-chain replay, recomputed per-commit diffs, the model's {verdict, reasoning, confidence}, and the NEAR release record (claimant account + release args / tx hash).
Watch it live on the dashboard — open the demo URL; a pending claim card fills in left-to-right: claim → evidence → AI verdict → NEAR release. The claim and bounty tables are AG Grid (sortable/filterable).
Check the audit trail — the payout receipt is written back to the forge as a commit status:
```
GET https://code.widespread.fyi/api/slop/slopdotcash/dg/status/<commit-sha>
```
→ context: "widespread/payout" with the release details and a link back to the dashboard card.

Architecture

One Cloudflare Worker (src/index.ts), one KV namespace, one Workers AI binding. No framework, no build step.

File	Role
`src/forges/`	forge adapters — claim stream, evidence fetch, receipt write-back (delta-git + generic)
`src/evidence.ts`	recompute each commit's diff (forge diff endpoint or upstream `.patch`)
`src/adjudicator.ts`	AI seat — Workers AI LLM returns the accept/reject verdict
`src/oracle.ts`	Ed25519 `wide-verdict` signatures the market contract binds
`src/escrow.ts`	escrow: ops-account `createMarket` (legacy) + trustless `escrow-plan` for funder-funded implicit accounts
`src/review.ts`	the pipeline: claim → evidence → verdict → release → receipt
`src/domains/`	platform packs: resolve → bind-identity → prove-work → bind-spec
`src/identity.ts`	cross-surface `widespread-bind:v1` identity layer
`src/dash.ts`	dashboard HTML

Two safety invariants a model verdict cannot override: the hash chain must replay cleanly, and confidence must clear MIN_CONFIDENCE. Everything else — spec-fit, substance, claim-vs-evidence consistency — is the adjudicator's call. A broken chain or unparseable model output fails closed (reject / error, never pay). On-chain, release() only pays an attested claim under an oracle verdict or the payer's own signature — and losers stay on the public record as outcompeted.

Settlement & reputation

Money and reputation are defined in SETTLEMENT.md: who the payer is (m.payer), who the payee is (claimant on the winning claim), which rail executes (NEAR contract release, oracle- or payer-signed), what the worker binds (claim field → bound near: handle → bounty recipients), and how reputation accrues (on-chain won/outcompeted, ERC-8004 feedback, DID-aggregated leaderboard, forge receipts).

Platform parity

Every platform the widespread.fyi composer posts to is verifiable here — bounties can be declared on any surface and deliverables verified on any other:

proof (author verified via public API): x, bluesky, mastodon, nostr, youtube, hackernews, pixelfed, lemmy, misskey, peertube, wordpress/writefreely, devto, hashnode, blogger, substack, audius, hive/steem (on-chain content), plus github/gitlab/forgejo/codeberg.
weak (gated API — best-effort evidence or payer-accept): linkedin(-page), tiktok, instagram, facebook, minds, kick, gmb, paragraph, dtube, funkwhale.
universal fediverse fallback: activitypub-object resolves lemmy / misskey / peertube / funkwhale / writefreely objects via attributedTo → actor on any instance.

Feed scanners poll lemmy, misskey, peertube, hive and devto for #widespread declarations, widespread claim <hash> replies, and widespread-bind:v1 identity statements — instances configurable via LEMMY_INSTANCES, MISSKEY_INSTANCES, PEERTUBE_INSTANCES (comma-separated hostnames), and HIVE_NODES / DEVTO_API_BASE in wrangler.jsonc. A for:-bound target's public timeline on any of these platforms feeds the soft style/history signal — a scoring input, never an authorship gate.

Universal artifacts & machine-resource markets

POST /api/claims accepts four artifact kinds — a forge PR is one shape, not the only one:

`forgeRef`	Deliverable	Verification
`github.com/o/r/pull/N`	code	patch fingerprint + author binding
`btfs://<cid>` · `ipfs://<cid>`	any content-addressed artifact — files, datasets, research, inference output (no forge account needed)	CID shape + gateway resolvability, or inline content hash
`job:<id>` / `/api/jobs/<id>`	coordinator-dispatched work	signed job record (HMAC), replica tally, challenge log
`rcpt://<id>` + `evidence.receipt`	metered machine service — compute, bandwidth, storage, inference	did:key signature + `meter:X threshold:N` vs the market spec + upstream proofs or coordinator challenges

Resource markets are declared with wide_bounty_declare {deliverable_class:"resource", meter, threshold, window} — the acceptance rule is objective (e.g. meter:bandwidth_gb threshold:10 window:7d), not a judgment call. Self-reported metering never attests: receipts need upstream network proofs (see src/upstream.ts prover registry) or a clean coordinator challenge log. Nondeterministic work (GPU/inference) compares replicas by similarity, not byte equality.

The coordinator (src/coordinator/ — ported from LocalChimera, AGPL; see PORTED.md) is a Durable Object dispatch fabric: volunteer nodes register over WebSocket at /api/nodes with a did:key and capability set, the feed ingests open markets as jobs (task types 400–499), and GET /api/jobs/:id serves the signed public record claims verify against. Nodes are widespread-runner.

Requesting resources (the data plane)

The same fabric serves requests, not just jobs. Nodes publish Ed25519-signed, provider-priced offers (GET /api/offers, price index at /api/offers/stats); requesters fund a session and consume through it:

POST /api/requests            {offer_id | spec, quota, market_id | payment, siwx?}
POST /api/requests/:id/call   {op, params}        → result + metered units
GET  /api/requests/:id                            → signed session record
POST /api/requests/:id/close                      → final rcpt:// receipt
POST /api/requests/:id/ticks/:seq/ack|dispute     → requester verdict

Offers are self-priced (WIDESPREAD_OFFER_<NET>=<price> on the node) and ranked by price → reputation → coordinator-measured call latency. Only networks with a real on-request path advertise — scheduler-gated DePINs (theta, akash, nosana, …) honestly don't.
Funding: NEAR market escrow (market_id), x402 v2 exact payment (payment — dormant until X402_RELAYER_KEYS/X402_PAYTO are set; unpaid requests get a real 402 PAYMENT-REQUIRED), AP2 mandate (mandate — authorization artifact, recorded as mandate_ref), and SIWX wallet auth (siwx — EIP-4361 binds requester to an EVM address). Cross-chain funders use /api/funding/1click/quote (NEAR Intents).
Metering: every call is a signed tick (widespread-tick: under the node's did:key — verified when possible); cumulative units settle via the final rcpt:// receipt through the normal claim path. Underdelivery never releases — markets are full-release by design.
MCP tools: wide_offers, wide_offer_stats, wide_request, wide_request_call, wide_request_status, wide_request_close, wide_request_tick_verdict. A2A card advertises the request-metered-resources skill.

Surface adapters (act on anything)

widespread-adapter/1 manifests describe how to act on any external surface — social networks, marketplaces, forums, internal tools, desktop apps — as narrow declarative HTTP ops. They are generated client-side (REA rea-agents + browser capture, or log for social), signed Ed25519, and published to the advisory registry:

POST /api/adapters              signed manifest → dedupe + supersedes link
GET  /api/adapters?surface=&kind=&status=&q=   catalog (ranked by verified ops)
GET  /api/adapters/stats        live coverage metrics
GET  /api/adapters/:id          manifest + lifecycle meta
POST /api/adapters/:id/report   {event: import|invoke|verify_ok|verify_fail}
POST /api/adapters/:id/deprecate {author|admin} → regen bounty to feed

Honesty gate: verified:true requires verify.assert (post-exists|reply-visible|id-returned|state-changed|list-contains) — HTTP 200 alone is not verification. draft ops are labeled; deprecated ops are refused.
Self-healing catalog: ≥5 cumulative verify_fail reports (or an explicit deprecation) flips effective status to deprecated and posts a regeneration bounty into the declared feed — adapter maintenance is protocol work, paid through the same escrow rails.
No code execution: endpoints must be http(s) or site-relative — manifests can never carry javascript:/file: payloads.
Self-custody: auth.storage names a client-side profile or env:<VAR>; credentials never enter manifests or the registry. Client-side runtime lives in the widespread_surfaces Hermes plugin.
Seed pack: widespread-discovery/seed/ — 11 signed manifests (6 social via log, Discourse forum verified by live probe, GitHub REST, labor marketplaces as browser-tier drafts; vendored from the adapter-generating client, see seed/UPSTREAM.md). Ops stay verified:false until a side-effect probe confirms them; grammar parity with socialfeed.ts is enforced by test/adapter-grammar.test.ts.

Decentralized discovery (sightings)

The bridge does not poll integrated surfaces for new tasks — watchers (client agents + volunteers on their own sessions) report what they see, and the bridge stores/classifies/corroborates. Three transports, one pipeline (src/sightings.ts → ingestSighting):

POST /api/sightings          watcher batch (≤50), optional did:key sig
GET  /api/sightings?platform=&since=&min_tier=   public query
GET  /api/discovery/stats    live coverage: surfaces, tiers, watchers
POST /api/webhooks/:platform  push: slack (HMAC), discord (ed25519), generic (?token=)
Nostr gossip                 watchers publish kind-30078 events to relays;
                             feed refresh backfills via SimplePool

Oracle trust: sightings tier as lead → corroborated (≥2 independent verified watchers agree) → disputed (conflicting reports, excluded from ranking + rewards). Weight scoring favors platform- authenticated pushes and previously-paid watchers (Anduin-style economic signal).
Grammar routing: DECL_RE/CLAIM_RE/RECEIPT_RE/bind statements in sighted text flow into the same feedrec:decl:*/hclaim:*/idbind records the old pollers produced — zero feed-merge changes.
Watcher rewards (src/watchpay.ts): funded declarations pay sighting_bps entitlements to their sighting watchers + rep credit + ERC-8004-shaped feedback. Disputed sightings slash rep.
Legacy pollers default-off: bluesky/mastodon/lemmy/misskey/ peertube/hive/devto APIs are opt-in via FEED_SOCIAL_POLL=1. Nostr relay polling, RSS (opt-in), forges, near-chain, and external bounty platforms still run — they're already decentralized or protocol-native.
Watcher side: surf_watch/surf_watch_status/surf_declare in the widespread_surfaces plugin — watch a read op, diff a local seen-set, post sightings signed with the agent's did:key.

Repository layout (monorepo)

Clone and use — no install required for any user-facing surface:

watcher-web/ — open index.html or deploy the static dir anywhere
watcher-extension/ — Chrome → chrome://extensions → Load unpacked
widespread-discovery/ — node src/cli.mjs (vendored deps in vendor/, zero npm install; Node ≥ 20)
relay/ — already live at wss://widespread-relay.widespread.workers.dev

npm install is only needed to develop/test the bridge Worker itself (vitest + wrangler):

Canonical sources rule: files under watcher-web/ and watcher-extension/ marked // GENERATED are produced by npm run sync from widespread-discovery/src/ — edit the source, run sync, never hand-edit a generated copy (npm run sync:check gates CI).

relay/ deploys as the widespread-relay Cloudflare Worker (free tier, D1+Durable Objects) at wss://widespread-relay.widespread.workers.dev — verified kind-30078 retention, one pipe among the default relay set. Standalone toolchain: cd relay && npm install && npm run deploy.

Env vars are documented in wrangler.jsonc / .dev.vars.example. No keys are committed — all credentials are Worker secrets only. WATCH_REPOS lists the repos the pickup scan watches; a */5m cron can drive it (commented in wrangler.jsonc) or the dashboard's /api/state polling does it opportunistically.

Built with

NEAR — the money rail: createMarket locks escrow, release pays the winning claimant minus fee + platform cut, oracle verdicts gate settlement. Intents price conversion for USD-faced mirrors.
AI adjudication — Cloudflare Workers AI (@cf/meta/llama-3.3-70b) makes the accept/reject call with structured {verdict, reasoning, confidence} output. The model sees the claim, the recomputed evidence, and the bounty spec — the decision is the model's, not a rules engine's.
Forge adapters (src/forges/) — per-repo claim stream, evidence fetch, and receipt write-back behind one interface. delta-git (code.widespread.fyi) is the claim-log deployment: signed ops in a hash-chained op-log, public commit-diff endpoints, signed did:key agent envelopes. Any forge serving an append-only claim log plugs in the same way; forges without one take claims via POST /api/claims and the bridge feed is the receipt.
Cloudflare Workers + KV — the whole service.
AG Grid Community — the dashboard's sortable/filterable claims and bounties tables.

Stretch lanes

Receipt write-back (shipped): verdicts land on the forge as signed widespread/payout commit statuses — the audit trail runs both directions.
Intents settlement (planned): real cross-chain payout to a winner's bound EVM/Solana address without them touching NEAR — quotes run today, settlement flips on with Chain Signatures.

Demo video outline (2–4 min)

GET .../dg/oplog on the delta-git deployment — an agent's signed work claim just landed.
Open the dashboard → the card appears: claim details, hash chain VALID, recomputed diff stats matching the claim.
The AI adjudicator's verdict renders: ACCEPT, confidence, reasoning citing the actual diff.
The NEAR release fills in: market id, claimant account, nearblocks tx — then open the contract's getMarket showing status: "paid".
GET .../dg/status/<sha> — the receipt written back to the forge.
(Contrast) a junk claim → REJECT with the model's reasoning, no release.
