Addresses & Parameters

Testnet: Base Sepolia (Chain ID 84532)

These are the live contract addresses on Base Sepolia as verified on-chain.

Contract	Address
Diamond (Port)	`0x5a2324aA18613FAD4e44bDF0d6c73Ec1f6D87ff8`
MACHINA Token	`0x7b9Bd0e5f9a4D0A01db18823De1D8442C84993b7`
USDC (Circle)	`0x036CbD53842c5426634e7929541eC2318f3dCF7e`
Treasury	`0xffe89e1f0a77C600Ad938b57180E5be3e3119f40`
x402 payment receiver (EVM)	`0x5a2324aA18613FAD4e44bDF0d6c73Ec1f6D87ff8` — the Diamond itself
x402 payment receiver (Solana)	`G53EbeTZSNsAn7bj6iMFUQnq3zpDdEbHhKkPRywo8bix`

The V2 contracts are a fresh deployment. SubnetFacet was removed and there is no in-place upgrade for jobs, so V2 is deployed to new addresses and existing miners are copied across by an admin import. If a call to the Diamond below reverts with an unknown selector, you are looking at the old deployment.

The Diamond is where x402 payments land. You don't need to hardcode it: every 402 response carries the address to pay in accepts[].payTo, and that is the value your client should use.

Every address above is readable from the Diamond itself, which is the source of truth if this table ever drifts:

bash

cast call DIAMOND "usdcToken()(address)"    --rpc-urlRPC   # escrow, jobs and settlement token
cast call DIAMOND "machinaToken()(address)" --rpc-urlRPC   # what miners are actually paid in
cast call DIAMOND "getTreasury()(address)"  --rpc-urlRPC

Network Configuration

Parameter	Value
Chain	Base Sepolia
Chain ID	84532
Canonical mainnet	Base (Ethereum L2)
RPC (Alchemy)	`https://base-sepolia.g.alchemy.com/v2/<YOUR_KEY>`
WSS (Alchemy)	`wss://base-sepolia.g.alchemy.com/v2/<YOUR_KEY>`

Node Endpoints (Live Testnet Node)

Service	URL
HTTP API	`https://devnode.telegraphprotocol.com`
WebSocket	`wss://devnode.telegraphprotocol.com/engine/ws`
x402 Facilitator	`https://facilitator.payai.network`

Engine and Daemon are the same node, reached via /engine and /daemon path prefixes on the HTTP API base above (e.g. https://devnode.telegraphprotocol.com/engine/v1/ask) — not separate services.

Active Miners (Testnet)

The live miner set changes as operators register and deregister on-chain, so there is no useful static list here. Read the current catalogue — with each miner's ID, endpoints, schemas, declared intents and floor price:

bash

curl https://devnode.telegraphprotocol.com/api/miners

A few long-standing ones, as a sample of what the network serves:

Miner	Intents
LiteLLM	CHAT_COMPLETION, LANGUAGE_GENERATION, TASK_COMPLETION, AGENT_TASK, WEB_SEARCH
Telegraph Chatbot	CHAT_COMPLETION, LANGUAGE_GENERATION, TASK_COMPLETION, AGENT_TASK, WEB_SEARCH, TELEGRAPH_KNOWLEDGE
Zeus (Bittensor SN18)	WEATHER_CHECK, WEATHER_FORECAST, STORM_ALERT
BitMind (Bittensor SN34)	DEEPFAKE_DETECTION, IMAGE_VERIFICATION, VIDEO_VERIFICATION, MEDIA_AUTHENTICITY_CHECK

Genesis Protocol Parameters

These parameters define the protocol's behaviour at launch. Governance-adjustable parameters can be changed by a 43/64 Validator majority after the active validator set reaches 43.

Tokenomics

Parameter	Value
Maximum MACHINA supply	21,000,000
Genesis daily emission	7,200 MACHINA
Halving interval	4 years (1,461 epochs)
Validator emission share	60%
Script Author emission share	20%
Treasury emission share	20%
Protocol fee	2% (200 basis points)
TWAP settlement minimum	100 USDC
TWAP drip size	0.01 USDC per drip
TWAP drip jitter	±30 seconds
Minimum signal floor price	0.01 USDC (10,000 in 6-decimal)

Validator & Consensus

Parameter	Value
Active Validator cap	64
BFT finalization threshold (τ)	43 / 64
Reduced consensus threshold (τ_reduced)	33 / 64 (activates after 3 failed rounds)
Minimum Validator stake bond	100 MACHINA
Unbonding period	21 days
Epoch duration	24 hours
Commit phase timeout	45 seconds
Reveal phase timeout	45 seconds
Leader failover timeout	90 seconds

Scoring & Penalties

Parameter	Value
Consensus deviation threshold (δ_c)	0.15 scoring units
Scoring module replacement margin	Challenger's win rate ≥ Canonical's + 2 points, on the same hidden sample
Scoring module minimum win rate	70% overall; 60% on each family child with ≥ 10 scored pairs
Minimum scored pairs per competition	10
Competition sample size	200 pairs
Evaluation Pool minimum contributors	5 per Intent
Testing Cohort size	10% of active Validators
Internal Audit Fee	2% of epoch Validator emission pool
Spot check frequency	About once per Intent per hour on average (node default; a node operator can change it with `SPOT_CHECK_INTERVAL_SECONDS`)
Routing revocation trigger	Consecutive failed spot checks (no response or an empty answer)
Category A ejection (continuous offline)	7 days unbroken
Category A ejection (rolling missed)	>50% of rounds in 7 days
Category B fraud slash	20% of stake → Treasury (permanent ban)
Category C strike window	5 strikes in 30 days → ejection
Front-running penalty	7-epoch emission forfeiture + liveness ejection

Miner

Parameter	Value
Registration cost	Gas only — no bond or stake
Grace period duration	7 days
Grace period routing share	5% flat (shared among all grace-period miners)
Miner routing (genesis)	70% top / 20% second / 10% third
Deregistration	Immediate — no unbonding period
Scoring module registration	Gas only — no bond

Demand Multiplier Tiers

24h Request Volume	Multiplier
0 – 999	1.0×
1,000 – 9,999	1.5×
10,000 – 99,999	2.5×
100,000 – 999,999	5.0×
1,000,000+	10.0×

For x402 pay-per-call inference, the charged price is min_price_usdc × multiplier, where the multiplier is selected from the rolling 24-hour request volume for that Intent. A miner's effective price rises automatically with demand and returns to the floor when demand subsides.

ERC-8183 jobs are priced differently. A job does not use the miner's min_price_usdc at all — it uses a single protocol-wide jobBasePrice, scaled by the same multiplier table. Read it with cast call $DIAMOND "getJobBasePrice()(uint256)"; on testnet it is currently 1000000 (1 USDC per job).

Gas & Escrow

Parameter	Value
Gas escrow multiplier (floor)	2.0× estimated gas
Gas escrow multiplier (ceiling)	5.0×
Escrow withdrawal timelock	4 hours
WebSocket minimum escrow	1.00 USDC
Discovery Tier participation minimum	95% of assigned rounds

Governance

Governance activates once the active Validator set reaches 43 Validators.

Proposals require a 43/64 majority (one vote per Validator regardless of stake size). Most parameters have a 14-day timelock after passing; structural changes (Validator cap, epoch duration, BFT threshold) have a 30-day timelock.

Emergency veto: 54/64 signatures cancel any proposal immediately. A vetoed proposal cannot be resubmitted for 90 days.

Permanently immutable (cannot be changed by governance):

Maximum supply: 21,000,000 MACHINA
Halving schedule
Emission tier percentages (60/20/20)
Zero pre-mine guarantee
