Gasper - ethereum.org
Aug 15, 2023 · Gasper is the mechanism defining how validators get rewarded and punished, decide which blocks to accept and reject, and which fork of the blockchain to build on. What is finality?
What is Gasper?. Understanding Ethereum’s Consensus… | by
Apr 16, 2024 · Gasper is the official name for Ethereum’s proof-of-stake consensus mechanism. Gasper, is a hybrid protocol created by combining LMD-GHOST and Casper the Friendly Finality Gadget.
What is Gasper, Ethereum’s new consensus protocol
Sep 10, 2022 · Gasper is the union of GHOST and Casper. It uses GHOST as the main consensus protocol with 5-min probabilistic finality, and adds a layer of ~20-min deterministic finality with Casper for...

Sep 29, 2023 · Combining the two in Gasper is an attempt to get the best of both worlds in terms of liveness and safety. In essence, LMD GHOST provides slot-by-slot liveness (it keeps the chain running), while Casper FFG provides safety (it protects the chain from long reversions).
Formally Verifying Finality in Gasper: The Core of the Beacon Chain
Jul 15, 2020 · In collaboration with the Ethereum Foundation, we have formalized the finality mechanism of Gasper in the general setting of dynamic validator sets using the Coq proof assistant. We state and prove...
We present “Gasper,” a proof-of-stake-based consensus protocol, which is an ide-alized version of the proposed Ethereum 2.0 beacon chain. The protocol com-bines Casper FFG, a finality tool, with LMD GHOST, a fork-choice rule. We prove safety, plausible liveness, and probabilistic liveness under different sets of assumptions.

In this document we present the evolution of the proof-of-stake consensus protocol of Ethereum, called Gasper, aiming at a self-contained reference for future study and research. ::: spoiler ::: info We include in spoiler boxes of this kind the implementation of the most relevant theoretical parts.
Modeling and Verification of Gasper - Musab A. Alturki, PhD
Gasper is an abstract proof-of-stake protocol layer that is implemented by the Beacon Chain protocol, the underlying protocol of the Ethereum 2.0 network. A key component of Gasper is a finality mechanism that extends the original Casper FFG protocol primarily with k-finalization.
A Performance Study of Block Proposing Mechanism in Ethereum …
This paper presents a simulation-based study that models the performance of the block proposing mechanism within Gasper. Our simulation results illustrate the impact of design parameters (e.g., block proposing interval) on throughput and non-forking probability.
