blockmachine

SN19 blockmachine answers questions that apps ask blockchains, like a call centre staffed by freelance operators who set their own price per call and are paid only for answers checked as correct.

The commodity, explained from zero

Every wallet, explorer and trading bot asks a blockchain questions: what is the latest block, what is this balance, did this transaction go through. Those questions go to an RPC endpoint, a server running a full copy of the chain, and running one is expensive. Blockmachine sells access to such servers for eleven chains, Bittensor and Ethereum among them, at a single address per chain. Usage is metered in Request Units, where a simple query costs 1 and a heavy one more.

The price list is public: a keyless free tier at 300 requests a minute, a $9 Standard plan for 5 million units a month, up to $999 for a billion. "Failed requests don't cost you anything." A calculator on the pricing page puts 100 million requests at $165 against $979 at Alchemy, a named competitor. The front page carries testimonials from three customers, including Taostats: "At 15 billion requests a month, we can't afford for our RPC layer to be the weak point."

Why it is on Bittensor at all

The technology page states the case as cost and trust: "Most supply is still centralized, opaque, and economically misaligned." Competing suppliers bid the price down, and every response can be checked. Here the call-centre comparison breaks: a call centre pays operators by the hour, while blockmachine pays only for answers a validator has re-run and matched, and an operator's unclaimed share is destroyed rather than shared.

How the work gets done

Miners, the operators, run their own chain node behind a gateway the network supplies, register it, and set a price in US dollars per unit of work. Customer requests are routed by a score that combines that price with quality, meaning latency, uptime and correctness, and a burst test measures each node under heavy load so strong hardware earns a bigger share. Validators, the auditors, read the gateway logs, re-run samples against reference infrastructure and compare results; a mismatch has no appeal, and the whitepaper provides for permanent bans. Each epoch of about 72 minutes, emission, the subnet's share of newly minted TAO, is paid in proportion to the units each miner served at its bid price.

How you would know it works

The buybacks page: "For every alpha token paid to miners, blockmachine purchases an equal amount of SN19 alpha" for a reserve, and it lists four settled cycles from May to August 2026, 4,812 alpha for $12,328 in total, each row linked to a Taostats transaction, last synced at block 9,033,809 on 2026-09-10. Anyone can call the free endpoint at rpc.blockmachine.io.

What is missing

The live performance and miner dashboards render empty without a browser. There is no status page and no service-level agreement; support is an email and a channel on the shared Bittensor Discord, and the chain's discord field is empty. The miner README registers on a testnet and gives no mainnet cost (about 1 TAO on chain on 2026-09-09). The chain's repository field is a one-file page linking to the real miner and validator repositories, and the chain description's wording appears nowhere on the site.

Metaphor: a call centre staffed by freelance operators. Every claim is drawn from the evidence set or the subnet's own materials; "(inferred)" marks a conclusion rather than a quote. Corrections.
