- Dec 26, 2021 · 3 years agoSure! The Bitcoin chain ensures security and prevents double-spending through a combination of cryptographic techniques and consensus protocols. When a transaction is made, it is broadcasted to the network and included in a block. Miners then compete to solve a complex mathematical puzzle to validate the block. Once the block is validated, it is added to the blockchain, which serves as a public ledger of all transactions. This decentralized nature of the blockchain makes it extremely difficult for any single entity to manipulate the transaction history or spend the same Bitcoin twice.
- Dec 26, 2021 · 3 years agoThe security of the Bitcoin chain is also maintained through the use of digital signatures. Each transaction is signed with the private key of the sender, which can only be verified with the corresponding public key. This ensures that only the rightful owner of the Bitcoin can initiate a transaction. Additionally, the blockchain relies on a consensus mechanism called Proof of Work, where miners must invest computational power to validate blocks. This makes it economically infeasible for an attacker to control the majority of the network's computing power and manipulate the blockchain.
