Pocket RelayMiner

Every relay you serve, paid on chain.

Pocket RelayMiner is the supplier side of Pocket Network: it serves relays from gateways to your backends on every transport, charges each one against the application's stake before serving it, and turns what it served into claims and proofs that settle on chain -- through crashes, restarts, Redis outages and partial rejections.

Measured for v0.1.0 on 1 relayer, 1 miner and 1 Redis: 10.7 M relays served at ~2,400 relays/s, through 4 session windows with 6 sessions of 50 suppliers each, and 1,501 of 1,501 claims settled, with the miner killed twice on purpose along the way. The numbers are in the capacity report.

Why operators run it

It gets every relay paid

• Claims and proofs are submitted automatically for every session, and watched until the chain includes them; what did not land is resubmitted while its window is still open.
• A claim or a proof is never lost to a crash, a rollout or a batch the chain partly refuses: the message the chain names leaves the batch, the rest goes through.
• Every relay is charged against the application's stake before it is served, so the relayer does not serve work the session can no longer pay for. If Redis cannot confirm the budget, the relay is refused rather than served for free.

It serves every transport

• JSON-RPC over HTTP, WebSocket, gRPC, REST and streaming (SSE), and CometBFT, routed to your backends per service.
• Ring signatures and sessions are verified on every relay, and every response is signed with the supplier's key.

It scales and survives failure

• Relayers keep no state of their own: all of it lives in one Redis, which every relayer and miner of a deployment shares.
• Miners elect a leader through Redis; a standby takes over when it stops.
• Memory and Redis are bounded at every stage: under pressure it refuses new work cleanly instead of running out of memory.

It refuses to run unsafe

• validate checks a config offline and lists every problem in one pass; --check-stake finds staked services with no backend.
• Both processes refuse to start on a Redis that could lose data (no maxmemory, an evicting policy, a version older than 8.10).

It shows you what it is doing

• Prometheus metrics with a triage order for incidents (docs/METRICS_TRIAGE.md).
• pocket-relay-miner redis decodes sessions, streams, claim trees, meters and every claim and proof submission straight from Redis.

It is built to build on

• pocket-relay-miner relay sends single relays and load tests on every transport, and simulated relays exercise a live relayer end to end without staking or billing anything (docs/SIMULATED_RELAYS.md).
• The bLSAG ring signature a relay carries is documented byte for byte, with working signers in Node.js, Python and Rust and a Go oracle to check yours (examples/relay-signing/).
• Supplier keys come from a keys file or a keyring and reload without a restart (docs/SUPPLIER_KEYS.md).

1 binary, 2 processes, 1 Redis shared by all of them, every process on the same version. v0.1.0 was tested on 1 relayer + 1 miner and on 2 relayers + 2 miners (the latter at lower load); the load tests and the capacity figures are from 1 relayer + 1 miner.

Where to start

Deploy. An AI agent starts at AGENTS.md: the rules and the invariants that stop a deployment.

I want to...	Read
choose a path, check prerequisites and ports	docs/deploy/README.md
run it with Docker Compose, on beta first	docs/deploy/DOCKER_COMPOSE.md
run it on a host, binary and systemd	docs/deploy/HOST.md
use Kubernetes	no example in v0.1.0; tilt/ runs the stack on a local kind cluster and is a starting point for your own manifests

Configure. The relayer reads its config once, at startup: restart it after every change.

I want to...	Read
see every key, its default and why to change it	config.relayer.example.yaml, config.miner.example.yaml
check a config against its schema	config.relayer.schema.yaml, config.miner.schema.yaml, and pocket-relay-miner relayer|miner validate --config <file>
set up Redis	config.redis.example.conf
set up supplier keys	docs/SUPPLIER_KEYS.md
start from a minimal config that works	examples/docker-compose/config/, examples/host/

Operate.

I want to...	Read

Understand.

I want to...	Read
follow a relay into a claim, a proof and a reward	docs/CLAIM_PROOF_LIFECYCLE.md
know when two relays count as one	docs/CLAIM_LEAF_MODEL.md
