Chainwork, mate, is a measure of the total computational effort that's been put into mining a blockchain. It's kind of like a scorecard for the miners.

In Bitcoin, you calculate chainwork by adding up the 'work' done on each block in the chain. The 'work' for each block is roughly proportional to how much computational power was needed to mine it.

So when you hear folks talking about "chainwork," they're really just talking about how much energy and computing power has gone into securing the Bitcoin network!

is It different from proof of work?

Yeah, mate, they're related but not quite the same thing.

Proof of Work (PoW) is a mechanism used to confirm transactions and produce new blocks in the blockchain. Miners have to solve complex mathematical puzzles - it's like a big competition with the prize being new bitcoins!

Chainwork, on the other hand, is more like a cumulative record of all that proof-of-work effort. It adds up all the 'work' that's been done on each block in the chain.

So you could say that PoW is about doing work for individual blocks, while chainwork measures all that work over time!

Do i understand this right, that there can be multiple POW on a block?
