The vision of TrueChain is to create a fair and transparent business world through the power of blockchain. We firmly believe that TrueChain technologies will reshape the business world, and TrueChain will live up to our supporters’ expectations. We will uphold our motto that “we will drive forward through our guiding principles that lay at the foundation of who we are.” Our mission is to continue to strive for excellence in all that we do.

The TrueChain Mainnet is officially launched!

TrueChain is committed to be the next generation of blockchain infrastructure. It is the world’s first public chain that implemented fPow+ PBFT hybrid consensus and has a strong global open source developer community supporting it. TrueChain provides the underlying public blockchain infrastructure with high performance, security for decentralized application (DApp) and global asset transaction.

TrueChain weekly report introduced a new section since September, 2019. We will share the “TRUE Development Program” — technical documentation and development guidance on a regular basis for TRUE fans to know more about TrueChain and encourage developers to develop in the TrueChain ecosystem. We look forward to have more excellent developers and teams to join us.

Greenbelt — Browser Plug-in Wallet (1)


GreenBelt is a browser plug-in for accessing distributed network nodes. It allows you to run Dapps on the TrueChain network in your browser, instead of building a TrueChain full node specifically for accessing DApp. It is currently available in Chrome and will be extended to other major browsers in the future.
GreenBelt is based on MetaMask MIT open source protocol extension development, and it has the same security. GreenBelt allows users to securely manage identities on different sites and secure signatures for transactions. All user information is only recorded in the local browser, because the corresponding mnemonic and private key must be kept securely after the account is created.
GreenBelt aims to provide TrueChain network DApp developers and users with simpler, safer and better connecting tools.
