Where Else besides Bitcoin Is the Merkle Tree Structure Used in Cryptocurrency?

Merkle Trees are fundamental to many blockchain and distributed ledger technologies beyond Bitcoin. They are used in Ethereum to verify transaction data, state data, and receipts, forming a Merkle Patricia Tree.

They are also employed in systems like Git for version control and in peer-to-peer file sharing protocols to ensure the integrity of file segments. Their efficiency for data verification makes them a cryptographic cornerstone.
