Where our numbers come from

Every number on Onchain Wiki comes from a named public source, and each page shows when it was last checked.

Where the Live Numbers Come From

The live numbers come from public data sources that publish their method:

  • Bitcoin blocks, fees, hashrate and addresses: mempool.space.
  • Prices and market share: CoinGecko.
  • Stablecoin supply by chain and total value locked: DefiLlama.
  • The Crypto Fear and Greed Index: alternative.me.
  • Bitcoin closes since 2010: blockchain.info's market price series.
  • Ethereum gas and chain checks: public RPC endpoints, called directly.

If a source fails at a check, the page keeps the last good number and its time.

How Facts Are Checked

Facts are checked against the primary source first: the issuer for token contracts, the chain's own docs for chain IDs and RPCs, the specification for standards such as BIP39. A contract address goes on a page only when the issuer lists it and a second source agrees. When two official sources disagree, the page says so.

How the Charts Are Made

The charts are made from Onchain Wiki's own fit to Bitcoin's closing prices, frozen on November 8, 2026 so the bands do not drift from day to day. The rainbow bands, the power law line and the cycle measurements all use that fit. They describe the past and are not forecasts.

Corrections

Corrections go to the editors through the contact page. A fixed error is corrected on the page, and the page's checked date moves to the day of the fix.
