Taproot
Taproot is an upgrade to Bitcoin. It makes some Bitcoin transactions more compact, less expensive, and more private.
What is Taproot?
Taproot has been active on the Bitcoin network since November 2021. It’s a soft fork: a change that remains compatible with older versions of Bitcoin software.
With Taproot, multiple digital signatures can be combined into one. A digital signature is proof that someone is allowed to approve a transaction. This means a transaction uses less data on the blockchain, the public record of transactions.
Taproot also helps with transactions that have extra conditions. Only the condition that’s actually used needs to be made public. This reveals less information than before.
An example of Taproot
Imagine that three people manage bitcoin together. They agree that at least two people must approve a payment. This is called multisig.
Without Taproot, multiple signatures are clearly visible on the blockchain. With Taproot, those signatures can appear as one joint signature. This makes the transaction look more like a regular Bitcoin payment and use less data.
Why is Taproot important in crypto?
Taproot makes more complex Bitcoin transactions more efficient. This matters for applications where multiple people need to sign or where a payment has conditions set in advance.
That’s why Taproot may come up in crypto news about Bitcoin, multisig, or the Lightning Network. Lightning is an additional network for Bitcoin payments that can process transactions faster. Taproot can help make channels on this network more compact and private.
The upgrade also gives developers more options for smart contracts. These are programs that automatically carry out agreements when certain conditions are met. Taproot doesn’t change what Bitcoin is, but it makes more types of transactions possible on the network.
