Cryptography is at the very core of what we do. We've proved that by building Aleph Zero — an unhackable blockchain platform.

the platform

Protocol,
Smart Contracts,

We're proud of our achievements. One of them is getting blockchain to 100,000 transactions per second with 2 second validation time.
