Blockchain Validation
In the Bitcoin network, transactions are not validated by a central authority, such as a bank. Instead, the validation process is performed by a decentralized network of nodes.
Each node in the network maintains a copy of the blockchain, a public ledger that contains a record of all Bitcoin transactions. When a new transaction is made, it is broadcasted to the network and propagated to all nodes.
When a node receives a new transaction, it performs a series of verifications to ensure its validity:
- Signature Verification: The node checks the digital signature of the transaction to confirm that it was authorized by the owner of the sending wallet.
- Double Spending Prevention: The node checks if the inputs of the transaction were not already spent in previous transactions. This prevents the same Bitcoin from being spent multiple times.
- Transaction Script Execution: The node executes the script attached to the transaction to verify that it meets the requirements set by the recipient’s wallet.
After these verifications, the node considers the transaction valid and includes it in the next block to be added to the blockchain. This block is then propagated to the network and added to all nodes’ copies of the blockchain.
This process of decentralized verification ensures the integrity of the Bitcoin network. Each transaction is independently validated by multiple nodes, making it extremely difficult for any malicious actor to manipulate the system.
Through this peer-to-peer validation process, the Bitcoin network achieves a high level of security and trust. It removes the need for a trusted third-party and allows individuals to have full control over their own funds.
