Fractal is powered by iChing, a bitcoin-like PoS consensus protocol with rigorous security proof and post-quantum guarantee. The protocol enables large-scale networks with millions of miners, thus, guarantees a truly decentralized blockchain.
On top of the iChing consensus, Fractal has a multi-level of performance amplification for achieving scalability. First, an extended consensus has been developed by utilizing the structure of iChing. Second, iChing is a natural mimic of Bitcoin consensus; as a result, scalability solutions for Bitcoin can be immediately used in Fractal. Altogether, Fractal can securely process 1,000x times more transactions comparing to legacy blockchains.
Fractal, with modular and composable design, will support a wide range of dApps. Further, regulation will be enforced so that dApps can safely interact and exchange services with each other as well as many dApps on other ecosystems whether they are public or private.

A Scalable Proof-of-Stake Blockchain in the Open Setting
Bitcoin and blockchain technologies have proven to be a phenomenal success. The underlying techniques hold huge promise to change the future of financial transactions, and eventually the way people and companies compute, collaborate, and interact. At the same time, the current Bitcoin-like proof-of-work based blockchain systems are facing many challenges.
We propose a new approach to constructing energy-efficient blockchain protocols. More concretely, we develop proof-of-stake based, scalable blockchain protocols in the open network setting
Fractal Platform Pitch desk
Fractal platform is a commercial-scale DApps platform. At the heart of Fractal is iChing consensus, a secure and eco-friendly proof-of-stake protocol. It is also a natural mimic of Bitcoin consensus, the only type that stands the test of time. On top of iChing, Fractal provides secure scalability solutions to handle 1,000x more transactions than legacy blockchain as well as near-instant finality. Finally, Fractal is built with modular, composable, and interoperable principles at every step to make building DApps a truly simple task that anyone can do.
