Scalability roadmap cheat sheet (version 2)

Scalability roadmap cheat sheet (version 2)

Here's an updated version, with new information from Vitalik's excellent post: The Limits to Blockchain Scalability (vitalik.ca)

TPS Now EIP-1559 (July 2021) zkPorter/StarkNet Validium release (Late 2021) The Merge (Late 2021) Data sharding (Late 2022?) Statelessness + state expiry (2022/23) Sharded execution (only if required) 640 shards (max possible)
Ethereum mainnet 18-54 Unchanged, but 36-109 in bursts Unchanged 20-65 >20-65 >60-200 4,000 – 12,000 40,000 – 120,000
Rollups 1,000-5,000 1,000-5,000 Unchanged 1,200-6,000 25,000 – 100,000 75,000 – 300,000 Unchanged 750,000 – 3,000,000
zkPorter/Validium >10,000 >10,000 25,000 – 100,000 Unchanged Unchanged, redundant? Definitely redundant!
Centralized sidechains / state channels Potentially millions, pick your poison Unchanged Unchanged Unchanged Maybe higher Higher still Higher still Some order of infinity

The original is here: Scalability roadmap cheat sheet : ethereum (reddit.com) so I won't go into details. Just two thoughts though:

– The 640 shards is obviously unsafe right now, as Vitalik's post argues, but could be a possibility over the decade as SSD costs continue declining. Obviously, it'll happen in steps. I also feel the rollup revolution is inevitable and the most likely outcome for L1 is a subset of shards have execution enabled years down the line, after stateless/expiry, with ZK proofs, while most shards remain focused on data availability.

– I'd like to know what a ZK-SNARKed L1 looks like! Maybe a future topic for Vitalik's blog?
