Blockchain 101: A Web Developer's Introduction
Blockchain is a decentralized database that stores transaction records across multiple computers. It is characterized by its immutability and transparency, allowing for secure and verifiable transactions. Solana is an example of blockchain technology that can process thousands of transactions per second.
- ▪Blockchain is a distributed database that maintains records across multiple computers in a network.
- ▪Once data is recorded on the blockchain, it is nearly impossible to change due to its cryptographic structure.
- ▪Transactions are verified by nodes in the network, ensuring security and preventing double-spending.
