Ethereum Network to Get Major Boost from SSF Roadmap, Says Vitalik Buterin

On Sunday, June 30, Ethereum co-founder Vitalik Buterin published a blog post explaining the path forward for Ethereum and how they may need to part ways with the epoch and location mechanism of its roadmap current focus on rollup. Buterin proposes a new SSF mechanism to improve transaction time latencies in the order of hundreds of milliseconds or even less.

Ethereum Considers Single-Slot Finality

Currently, Ethereum Gasper consensus uses a slot and epoch mechanism in which validators vote in each 12-second slot. Additionally, all validators are given the opportunity to vote once, across 32 slots. Later, a PBFT-like consensus algorithm takes over after two epochs (12.8 minutes), thus providing a strong economic assurance known as finality. However, this approach raises two major concerns.

1. The complexity and several bugs in the interaction between the two slot-by-slot voting mechanisms as well as the epoch-by-epoch finality mechanism.
2. The finality period of 12.8 minutes is quite slow and inconvenient for users.

To simplify this, Buterin proposes a single-slot finality mechanism similar to the Tendermint consensus, in which block N is finalized even before block N+1 is created. The main difference with Tendermint is the retention of the “idle leak” mechanism. This will allow the Ethereum blockchain to continue and recover even if nearly a third of validators go offline. Vitalik Buterin calls this a Secure Speed ​​Finality (SSF) mechanism.

Addressing some challenges with the SSF mechanism

Vitalik Buterin also highlighted some key challenges associated with single-slot finality (SSF) in the Ethereum ecosystem. He explained that the naive implementation of SSF would require each Ethereum staker to publish two messages every 12 seconds, imposing a significant burden on the Ethereum network. blog post

Buterin said:

“While there are some clever ideas to mitigate this problem, including Orbit’s recent SSF proposal, it remains a challenge. While SSF greatly improves the user experience by speeding up “finality,” it does not eliminate the need for users to wait 5-20 seconds.”

When implementing the SSF mechanism in Ethereum, Buterin suggests implementing Orbit-like techniques to reduce the total number of validators signing per slot and achieve the key goal of reducing the minimum staking of 32 ETH .

“This approach could result in an increase in the slot time to around 16 seconds,” Buterin added. However, he added: “Designs like Orbit SSF are very recent, which suggests that the design space for designs in locations and eras where something like Orbit SSF is the era is still quite underexplored.”

Ethereum developers are still looking for the ideal solution to improve the purpose. Last month, Buterin shared the updates made with Ethereum Layer 2 Solutions. Ethereum L2 activity recently reached new all-time highs.

Ethereum Layer 2 Explosion recently announced the launch of its native token and airdrop BLAST.
