How is IOST different from other scaling solutions?
Unlike many existing scaling solutions, the IOS blockchain is an on-chain solution, which means IOS blockchain does not have to deal with security issues caused by on-chain and off-chain communication.

Secondly, IOS is a decentralized scaling solution, which does not depend on any third parties and does not have single points of failures.

Thirdly, many scaling solutions are using PoS as their consensus solution. IOST’s POB mechanism, a variant of the PoS that we believe is a major improvement, can provide better performance without causing issues like centralization and security problems.
