While numerous blockchain networks exist worldwide, in many cases, the chain's administrator is not transparent and faces significant legal and technical challenges, making it difficult to promote web3 businesses on such platforms. In light of growing concerns about fraud and other risks, there's an increasing demand for blockchains that adhere to national regulations and guarantee secure business transactions.

Japan Open Chain was established to solve those problems. As it is fully compatible with Ethereum, it offers rapid transactions at a low cost, adequate decentralization, and high security and stability. In addition, with reputable Japanese companies onboard as validators, this public chain ensures both legal and technical practicality.
