Study Notes
- The blockchain is a decentralized, transparent and tamper-proof system for recording transactions.
- It was invented to improve trust in financial transactions.
- It works by having a network of nodes (computers) that each keep a copy of the blockchain.
- Whenever someone wants to make a transaction, they send their information to all the nodes in the network.
- The nodes then check to make sure that the information is correct and that the sender has the appropriate rights to make the transaction.
- Once the nodes have verified the information, they add it to the blockchain.
- The blockchain is constantly growing as more transactions are added.
- The blockchain is resistant to censorship and fraud.
- The blockchain is a digital ledger of all cryptocurrency transactions.
- Each block in the blockchain contains a cryptographic hash of the previous block, a timestamp, and transaction data.
- Nodes use the blockchain to validate transactions and to create new blocks.
- Blocks are added to the blockchain by miners.
- The blockchain is decentralized, meaning that there is no central authority that can control or modify the blockchain.
- Bitcoin is the first and most well-known cryptocurrency based on the blockchain.
- Other cryptocurrencies, such as Ethereum, use the blockchain to store their own transaction data.
