There are three main types of blockchain data:
Transaction data: Transaction data is information about each transaction on the blockchain API network, including sender and recipient addresses, transfer fees, transaction amounts, etc.
Block data: Block data is information about each block in the chain. For example, this includes hashes, transactions, timestamps, miner fees, etc.
Smart contract data: Smart contract data is all the information about smart contracts deployed to the blockchain API network. This includes the contract code, status, logs, and emitted events.
In summary, blockchain data is all publicly available information stored on Ethereum, BSC, Polygon, and other networks.
Blockchain data on networks like Ethereum, BSC, and Polygon is public, which means anyone can query the information. However, how exactly does this work?
Well, you have a few options when it comes to getting on-chain data:
Run the node: The first option to get blockchain API data is to host the node yourself. This allows you to interact directly with the blockchain network to query data, execute transactions, and deploy smart contracts.
Block Explorer: Your second option is to use a block Explorer. Block Explorer is a web-based platform that allows you to seamlessly read all transactions stored on the network. Some prominent examples include Etherscan, PolygonScan, BscScan, etc.
Web3API: The last option is to use Web3API. The Web3 API (short for "Application Programming Interface") is a set of protocols, rules, and methods that allow you to interact seamlessly with the network, such as querying blockchain API data.
