Twitter founder and CEO Jack Dorsey has launched his own Bitcoin node.
He revealed it himself, obviously on Twitter, showing a screenshot of the code and typing:

Bitcoin nodes are the software that stores and verifies the blockchain. Anyone can download the corresponding software and run it freely on their own machines.
There are currently 7,539 public nodes on the Bitcoin network, but it is estimated that there are many more.
It is possible to install a node privately to simply verify the blockchain, or to install it and make it public to contribute to the validator network.
Installing and running a full Bitcoin node is not a particularly easy thing to do, which is why the vast majority of users do not.
At one point, when Bitcoin was created, the node software was effectively all there was, so anyone who wanted to use Bitcoin had to install it. But then standalone wallets were also created, which can work perfectly well without the hassle of having to run a node.
Node software is specifically required for monitor and verify the blockchain, so anyone who does not want to trust a third party and wants to verify for himself that everything works correctly must run a node.
Why did Jack Dorsey install a Bitcoin node?
Jack Dorsey did not specify the reasons that convinced him to install and run a Bitcoin node, but given the growing engagement in this area from Twitter and Square, the companies he founded and leads, the motivation is likely to be in need of monitor and verify the blockchain without having to depend on third parties.
Dorsey has become increasingly involved in Bitcoin, so much so that a few days ago retweeted a tweet from Documenting Bitcoin reporting that the City of Miami was considering giving its employees the opportunity to they will pay their salaries in bitcoin, commenting "smart".
Furthermore, the founder of Twitter has long been convinced of the merits of the Bitcoin project. In May three years ago, he said that he expected BTC to become the currency of the internet.
