Blockchain
A blockchain is a distributed digital ledger that records transactions across a network of computers. Each transaction is grouped into a "block" and cryptographically linked to the previous block, forming a chain that's effectively impossible to alter retroactively. This is what gives Bitcoin and Ethereum their security and transparency.
For most lending purposes, what matters is: blockchain records are public and verifiable, transactions settle in minutes (vs days for bank wires), and proof of ownership doesn't depend on trusting any single institution.
