ALGORAND Public Ledger

Hari Kishore Chaparala

Abstract: ALGORAND is one of the celebrated public ledger technologies. In this talk, we see how ALGORAND addresses the scalability problem in conventional blockchains and discuss its core aspects like cryptographic sortition and a fast Binary Byzantine Agreement protocol with soundness equal to 1 in a weakly synchronous network with a strong adversary. We also see a Proof-of-Stake based approach to handle Sybil attacks in a permissionless setting. Finally, we discuss some possible limitations.
