Jack Dorsey begins running his own bitcoin node

Jack Dorsey, the CEO of Twitter and Square, began running his own Bitcoin node on February 5, 2021. He shared an image on Twitter showing the node in the process of synchronizing with the Bitcoin blockchain, with the caption "Running #bitcoin". This action by Dorsey is significant as it demonstrates his personal involvement in the validation of transactions and blocks on the Bitcoin network, which is essential to the functioning and integrity of the blockchain.
 

Running a node allows Dorsey to participate in the Bitcoin network more directly, as nodes are responsible for keeping a full copy of the blockchain and validating transactions. His decision to run a node aligns with his long-standing support for Bitcoin and his belief in its potential as a future currency for the internet. Dorsey’s node was set up on a Mac computer using the high-performance ARM-based M1 chip, indicating his preference for powerful and efficient hardware for this purpose.
