How does the blockchain technology work?
Can you explain how nodes validate transactions?
Of course. Nodes validate transactions by solving complex mathematical puzzles using their computing power. Each node competes to solve the puzzle, and the first one to solve it gets to add the next block to the chain. Once the block is added, all the other nodes on the network verify its validity, and if it is deemed valid, it is added permanently to the chain. This process is known as proof of work, and it helps to ensure the security and integrity of the blockchain.
