Cadence: Extreme Pipelining with Multiple Concurrent Proposers
Kushal Babel, Fatima Elsheimy, Lioba Heimbach +6
We present Cadence, a Byzantine fault-tolerant multi-proposer consensus protocol with arbitrarily low block intervals, optimal resilience, and optimal fast-path latency. Cadence di…
EVM Workloads in the Wild: Evidence for Multi-Dimensional Gas Metering, State Growth, Delayed Execution, and Parallelism
Lioba Heimbach, Kushal Babel, Jason Milionis
Gas metering on EVM-compatible blockchains assumes that execution conditions are stable: that the resource mix is constant enough to justify collapsing execution costs into a singl…
Multiple Sides of 36 Coins: Measuring Peer-to-Peer Infrastructure Across Cryptocurrencies
Lucianna Kiffer, Lioba Heimbach, Dennis Trautwein +2
Blockchain technologies underpin an expanding ecosystem of decentralized applications, financial systems, and infrastructure. However, the fundamental networking layer that sustain…
On the Lifecycle of a Lightning Network Payment Channel
Florian Grötschla, Lioba Heimbach, Severin Richner +1
The Bitcoin Lightning Network, launched in 2018, serves as a layer 2 scaling solution for Bitcoin. The Lightning Network allows users to establish channels between each other and s…
Dissecting the EIP-2930 Optional Access Lists
Lioba Heimbach, Quentin Kniep, Yann Vonlanthen +2
Ethereum introduced Transaction Access Lists (TALs) in 2020 to optimize gas costs during transaction execution. In this work, we present a comprehensive analysis of TALs in Ethereu…
Ethereum Proof-of-Stake Consensus Layer: Participation and Decentralization
Dominic Grandjean, Lioba Heimbach, Roger Wattenhofer
In September 2022, Ethereum transitioned from Proof-of-Work (PoW) to Proof-of-Stake (PoS) during "the merge" - making it the largest PoS cryptocurrency in terms of market capitaliz…
Ethereum's Proposer-Builder Separation: Promises and Realities
Lioba Heimbach, Lucianna Kiffer, Christof Ferreira Torres +1
With Ethereum's transition from Proof-of-Work to Proof-of-Stake in September 2022 came another paradigm shift, the Proposer-Builder Separation (PBS) scheme. PBS was introduced to d…
A Fair and Resilient Decentralized Clock Network for Transaction Ordering
Andrei Constantinescu, Diana Ghinea, Lioba Heimbach +2
Traditional blockchain design gives miners or validators full control over transaction ordering, i.e., they can freely choose which transactions to include or exclude, as well as i…
FnF-BFT: Exploring Performance Limits of BFT Protocols
Zeta Avarikioti, Lioba Heimbach, Roland Schmid +3
We introduce FnF-BFT, a parallel-leader byzantine fault-tolerant state-machine replication protocol for the partially synchronous model with theoretical performance bounds during s…
