Blockchain emerged as a revolutionary technology whose application went beyond cryptocurrencies. But as its adoption spread, its inherent limitations were exposed. It was a verification system that could not do without miners and it became heavier and slower as more blocks and chains were added.

Like blockchain, Tangle is a data verification system. But while blockchain is a public ledger system that utilizes blocks. Tangle applies the directed acyclic graph (DAG) protocole.
