Block proposer randomness refers to the unpredictable selection of a network participant to create the next block in a blockchain. This mechanism is vital for maintaining network integrity and preventing malicious actors from predicting or manipulating block creation order. It ensures fairness and security within proof-of-stake or similar consensus systems. The method helps distribute block rewards equitably among validators.
Context
The topic of block proposer randomness is central to discussions on decentralization and censorship resistance in proof-of-stake blockchains. Achieving truly unpredictable randomness is a complex cryptographic challenge, often involving verifiable delay functions or distributed random beacon protocols. News often reports on advancements or vulnerabilities discovered in these randomness generation schemes, impacting protocol stability.
Proof-of-Spiking-Neurons introduces a new consensus class, modeling block proposal as competitive neural firing to achieve BFT security with minimal overhead.
