Key Technical Advantages:
Separating Consensus & Compute: Flow's architecture splits consensus (selection and ordering of transactions) from compute (execution of transactions and recording their output). This separation increases throughput by a factor of 56 without compromising security or decentralization and preserves ACID guarantees.
Block Formation: Flow uses a variant of the HotStuff consensus algorithm for Consensus Nodes to reach consensus on blocks at every block height. The second technical paper formalizes block formation and the Proof of Stake-based consensus process, addressing the Consensus role's responsibility in mitigating network challenges.
Execution Verification: The third technical paper formalizes Flow's verifiable computation scheme, providing proofs of safety and liveness under reasonable Byzantine assumptions. It is believed that this result could be adapted to other scenarios involving Bulletproofs, TrueBit, TEEs, and other verifiable computation schemes.
SPoCK (Specialized Proofs of Confidential Knowledge): This novel cryptographic technique was first outlined in Technical Paper 3 to address the Verifier's Dilemma. It formally defines the SPoCK scheme and its required security properties, introducing a novel implementation based on BLS signatures that is more concise and efficient.
Adaptability & Extensibility: Flow's architecture is designed to be adaptable and extensible, with the potential to incorporate various verifiable computation schemes and cryptographic techniques. This flexibility allows Flow to cater to various use cases and scenarios, ensuring a robust and future-proof blockchain platform.
