Proof of Work (PoW)
To maintain the security and integrity of the blockchain, Bitcoin uses a consensus mechanism known as Proof of Work (PoW). It’s an essential part of the mining process described above.
PoW is a mechanism created along with Bitcoin to prevent double-spending in digital payment systems. Besides Bitcoin, many cryptocurrencies use PoW as a method for securing their blockchain network.
When we talk about a “complex math problem” that miners have to solve, we are basically talking about PoW. It was designed to make it expensive to create a block, but cheap to verify that it's valid. Suppose someone tries to cheat with an invalid block. In that case, the network immediately rejects it and the miner is unable to recoup the cost of mining.#BinanceHODLerTree #BTC #Write2earn
