iZ³, our blockchain product
iZ³ is our own product, just like our SaaS services: an open-source blockchain platform that powers a range of commercial systems: from decentralized registries and document verification to payment systems and digital financial assets. On top of it we build smart contracts and new solutions for clients.
iZ³ platform
Built for business networks
Open source under Apache-2.0. 50,000+ transactions per second in tests, free-format blocks, public or private networks, runs even in a browser.
Smart contracts
JavaScript and Solidity
Turing-complete EcmaContracts in JavaScript run in an isolated VM and talk to off-chain systems. For Ethereum-compatible networks we write and audit Solidity.
LCPoA · GOST
Consensus without mining farms
Our Limited Confidence Proof-of-Activity consensus withstands 51% attacks without costly hardware. GOST signatures with CryptoPro and VipNet give records legal force.
