What is Taproot? It’s not a carrot or a turnip, but a Bitcoin update that promises to keep some transaction details buried deep in the metaphorical soil.
Taproot is on track to be the biggest Bitcoin upgrade since 2017, which led to a hard fork of the network—in which one blockchain splits into two separate ones. Though Taproot isn’t quite as contentious, it’s worth understanding how it would alter the world’s biggest blockchain network.
What is it addressing?
The Bitcoin blockchain is composed of computer code. So, when you send a transaction on it, the “coins” are really connected to a script. These commands tell the blockchain what you can do with them. Usually, that means using a private key to provide a signature and prove you are able to spend them.
But people can make more complex transactions (i.e., smart contracts, or code that defines an agreement between a sender and receiver), such as requiring multiple signatures before coins can be spent or mandating a waiting period
