Explorer for NFTs – useful since NFTs have much more metadata to consult than a simple cryptocurrency transaction, and are sold in different marketplaces.Examples are The Graph and Chainlink, with the subgraph explorer /explorer and the oracle request. Layer 2 explorers and protocols – These refer to Layer 1 dependent chains, multichain or cross-chain projects.Popular examples of explorers for these networks are in order:, etherscan.io,, cardanoscan.io,. Layer 1 explorers – They read and ‘query’ independent blockchains, which do not rely on any other infrastructure, such as Bitcoin, Ethereum, Polkadot, Cardano or Avalanche.
In this regard, we can identify 4 macro categories of block explorers: We have briefly explained how a blockchain explorer works, however the process outlined is generic because there are different types in fact, there are many kinds of chains and protocols. For example, I can search for a utility token or stablecoin to find the smart contract through which it was issued.So if we look at an Ethereum ERC-20 token like USD Coin, for example, we can look it up on etherscan.io and see all the d ata about the token, such as the circulating supply, the most recent transactions, the wallet addresses that hold it (Holders) and the smart contracts in which a certain amount is locked.
#BLOCKCHAIN TRANSACTION EXAMPLE SOFTWARE#
Smart contracts – for blockchains that support them, it is possible to view all the information of the software built on them, i.e.The explorer also evaluates the size of the entire blockchain, the size of individual blocks, the average number of transactions per block, the average confirmation time, etc

Blocks – you can view all the information contained in the blocks of the entire chain, reconstructing the history back to the genesis block.Mempool – collects transactions waiting to be recorded in the blockchain, the explorer reports on them.Transactions – it is possible to check the transaction history of any address on the Blockchain, as well as to monitor trades in real time and have an estimate of the total daily volume.In particular, the information that is already available on the homepage or in specific sections of a blockchain explorer concerns these aspects:
