Merkle trees are essentials in Bitcoin and other cryptocurrencies. Specifically, they are an integral component in every block. Learn more about their function below.
The Merkle root serves a couple of purposes in this case. Let’s take a look at their applications in cryptocurrency mining and transaction verification.A Bitcoin block is made up of two pieces. The first part is the block header, a fixed-size segment containingfor the block. The second part is a list of transactions whose size is variable, but tends to be much larger than the header.
Miners need to repeatedly hash data to produce an output that matches certain conditions to mine a valid block. They can make trillions of attempts before finding one. With each attempt, they change a random number in the block header to produce a different output. But much of the block remains the same. There can be thousands of transactions, and you’d still need to hash them every time.
A Merkle root streamlines the process considerably. When you start mining, you line up all of the transactions you want to include and construct a Merkle tree. You put the resulting root hash in the block header. Then, when you’re mining, you only need to hash the block header, instead of the whole block.
This works because it’s tamper-proof. You effectively summarize all of the block’s transactions in a compact format. You can’t find a valid block header and later change the transaction list, because that would change the Merkle root. When the block is sent to other nodes, they calculate the root from the transaction list. If it doesn’t match the one in the header, they reject the block.There’s another interesting property of Merkle roots that we can leverage.
