BLOCKCLOCK is a Bitcoin data display device produced by Coinkite, the Canadian Bitcoin hardware company also behind COLDCARD, OPENDIME, and other self-custody tools. BLOCKCLOCK's Twitter Score is 27 out of 1000 as of July 2026, ranking #41,070 (top 10%) among 531,432 tracked accounts.
BLOCKCLOCK surfaces Bitcoin price, block height, Moscow time, sats per dollar, Opendime balances, QR codes, and custom messages across seven E-Ink displays. The device can verify an Opendime offline before displaying an address QR code, with balance lookups triggered only when the user presses a button, keeping network queries on demand rather than continuous. BLOCKCLOCK also supports broadcasting signed Bitcoin transactions directly, including those signed by a COLDCARD and loaded via MicroSD card, making it a functional bridge between air-gapped signing and the live network.
BLOCKCLOCK is affiliated with the broader Coinkite product family, which spans COLDCARD, OPENDIME, and BLOCKCLOCK micro, among other self-custody hardware. The account has published 1,662 posts and has been active since 2018. BLOCKCLOCK has been mentioned by 105 accounts, with 335 total mentions.
