Verification in blockchain is a consensus mechanism based process.Since blockchain acts as a decentralized ledger with multiple nodes in the network, the transaction must be verified by all nodes. During the process of creating a new block, the transactions are hashed and a unique output or result is created.
What is the purpose of the Blockchain?
A global network of computers uses blockchain technology to jointly manage the database that records Bitcoin transactions. That is, Bitcoin is managed by its network, and not any one central authority. Decentralization means the network operates on a user-to-user (or peer-to-peer) basis.
What is th s?
Hash rate denominations. 1 kH/s is 1,000 (one thousand) hashes per second. 1 MH/s is 1,000,000 (one million) hashes per second. 1 GH/s is 1,000,000,000 (one billion) hashes per second. 1 TH/s is 1,000,000,000,000 (one trillion) hashes per second.
How many hashes are in a Bitcoin?
Together this provides enough info to give an approximate answer to your question: hashes per bitcoin = (network hash rate) / (25 BTC per 10 minutes) = (180 * Th / s) / (25 * BTC / (600 * s) ) = 180 * 600 / 25 * Th / s / BTC * s = 2,700 Th / BTC = 2,700,000,000,000,000 h/BTC.
