What is Block Chain ?

Blockchain is a decentralized, distributed ledger technology that records transactions across multiple computers in a way that makes them tamper-resistant and immutable. Each block in the chain contains a cryptographic hash of the previous block, along with transaction data, creating a secure and transparent record of transactions. It's most commonly known for its use in cryptocurrencies like Bitcoin, but its applications extend to various industries such as finance, supply chain management, healthcare, and more.#HotTrends #ETH #Halvingwhitbianance #BTC #eft
