Plain-English explainers for block explorers, transaction hashes, addresses, and cross-chain lookup.
- Address format by chain: a cheatsheet - A reference table of address formats across major chains - length, encoding, prefix, example shape - drawn from the live tx.taxi classifier.
- Block hash vs transaction hash: what's the difference? - Block hashes and transaction hashes both look like 32-byte hex strings, but they identify very different things. Here is how to tell them apart and use each.
- EVM vs Solana addresses: format, derivation, and lookup - EVM addresses are 20-byte hex with EIP-55 checksums. Solana addresses are 32-byte base58 ed25519 public keys. Here is why that matters.
- Find any blockchain transaction in 30 seconds - Paste a hash, get the right explorer. A practical walk-through of looking up any blockchain transaction with tx.taxi when you do not know the chain.
- How to read a transaction hash - A transaction hash is a unique fingerprint of one blockchain transaction. Learn the format on EVM, Solana, and UTXO chains, and how to look one up.
- UTXO vs account model: which explorer should you use? - Bitcoin uses UTXOs. Ethereum uses accounts. The data model shapes what an address means and how block explorers display it.
- What is a block explorer? - A block explorer is a web app that indexes blockchain data so you can look up addresses, transactions, and blocks by their identifiers.
- What is an EVM L2? - An EVM L2 is a Layer 2 network that runs EVM smart contracts and settles to Ethereum. Here is what rollups are, how they differ, and how lookups work.
