Accountable Safety for Rollups
Ertem Nusret Tas, John Adler, Mustafa Al-Bassam +3
Accountability, the ability to provably identify protocol violators, gained prominence as the main economic argument for the security of proof-of-stake (PoS) protocols. Rollups, th…
Goldfish: No More Attacks on Ethereum?!
Francesco D'Amato, Joachim Neu, Ertem Nusret Tas +1
The LMD GHOST consensus protocol is a critical component of proof-of-stake Ethereum. In its current form, this protocol is brittle, as evidenced by recent attacks and patching atte…
Bitcoin-Enhanced Proof-of-Stake Security: Possibilities and Impossibilities
Ertem Nusret Tas, David Tse, Fangyu Gai +3
Bitcoin is the most secure blockchain in the world, supported by the immense hash power of its Proof-of-Work miners. Proof-of-Stake chains are energy-efficient, have fast finality…
Two Attacks On Proof-of-Stake GHOST/Ethereum
Joachim Neu, Ertem Nusret Tas, David Tse
We present two attacks targeting the Proof-of-Stake (PoS) Ethereum consensus protocol. The first attack suggests a fundamental conceptual incompatibility between PoS and the Greedy…
Light Clients for Lazy Blockchains
Ertem Nusret Tas, David Tse, Lei Yang +1
Lazy blockchains decouple consensus from transaction verification and execution to increase throughput. Although they can contain invalid transactions (e.g., double spends) as a re…
Babylon: Reusing Bitcoin Mining to Enhance Proof-of-Stake Security
Ertem Nusret Tas, David Tse, Fisher Yu +1
Bitcoin is the most secure blockchain in the world, supported by the immense hash power of its Proof-of-Work miners, but consumes huge amount of energy. Proof-of-Stake chains are e…
