A small desk display for people who check the block height more often than they'd like to admit: block height, BTC price, and "Moscow time" (sats-per-dollar), always on.
Assembled and tested. Connects over Wi-Fi and is ready to go out of the box — see "Where the Data Comes From" below before you decide what you want it to trust.
Out of the box, ClockChain trusts a third-party API the same way a browser tab would — it is not running its own consensus validation. See below before assuming otherwise.
By default, ClockChain connects to your Wi-Fi and pulls block height from a public block explorer API and price from a public market-data API. That's convenient, but it means the numbers on your desk are only as trustworthy as those third-party services — the same trade-off as checking a block explorer website. This is not the same as full-node validation, and we're not going to pretend otherwise.
If you run your own Bitcoin full node, ClockChain can be pointed at your node's RPC or Electrum server instead, for the block height specifically. That piece then becomes self-verified — you're reading it from consensus rules you're enforcing yourself, not trusting someone else's API response. Price still comes from an external market feed either way, since price isn't a blockchain-native fact any node can produce on its own.
If "don't trust, verify" matters to you for this device specifically, run it against your own node. If you just want a nice desk clock, the default setup works fine — just know which one you're getting.
