Say Bye-Bye to High ETH Fees – ‘Rollups Beats Sharding’

Vitalik Buterin, Ethereum (ETH) Co-founder, took his new proposal to the board to secure high fees on the network a thing of the past sooner than originally anticipated.

Reviewing his ETHOnline Kickoff Summit offering last Friday, Buterin wrote in a Twitter thread today that his motion for Ethereum 2.0 is “not “rollups instead of sharding,” it’s “rollups on top of sharding.”

Rollup is a scaling technique that grasps transaction data on-chain, in a compressed form, but the calculation is pushed off-chain. Meantime, sharding splits the blockchain’s nodes into smaller groups, known as ‘shards.’ Rather than verifying the same transactions concurrently, various shards then verify different sets of transactions, whereby raising the number of transactions that can be processed per second.

Buterin continued that “rollups are already here or coming soon even before sharding, and rollups without sharding still offer that 100x increase in throughput. So get on a rollup today!

Points are becoming increasingly packed with the network’s rising reputation and the decentralized finance (DeFi) boom. The way the system deals with this currently, said Buterin, is with higher fees – which recently hit a new all-time high.

The [layer 1] is nearly unusable for many classes of applications,” wrote Buterin, “and there’s no non-[layer 2] path that can get us to scalability in the short-to-medium term.”

Layer 1 (L1) is the base protocol (the Ethereum blockchain), while Layer 2 (L2) is any protocol built on top of Ethereum.

It is Phase 1.5, which is an interim update, or ETH 1.0 to ETH 2.0 merger phase, when a scalable proof-of-stake (PoS) network could already be reached instead of waiting until Phase 2, by using shard chains as data availability layers and rollups as the execution environments instead of the shards. Or, as Buterin wrote in a recent post: “phase 1.5 and done.

He proposed a scaling roadmap for which he said encompasses the next 1-2 years and includes “combining the scaling mechanism of sharding with the scaling mechanism of rollups.”

This follows the post cited above in which Buterin suggested “a rollup-centric [E]thereum roadmap” wherein “the Ethereum ecosystem is likely to be all-in on rollups (plus some plasma and channels) as a scaling strategy for the near and mid-term future.”

Buterin contended that base-layer scalability for applications is not coming until Phase 2, “which is still years away.” At the same time, “[ETH 2.0’s] usability as a data availability layer for rollups comes in [P]hase 1, long before [ETH 2.0] becomes usable for “traditional” layer-1 applications.”

ETH 1.0 clients could be repurposed as hopeful rollup clients, he said, while the future needs to see all users’ primary accounts, balances, assets, etc., as well as Ethereum apps and Ethereum Name Service domains, entirely inside a layer 2, instead of their current home, layer 1.

“The main reasoning Vitalik gives for focusing our energy on this rollout plan instead of on getting to [P]hase 2 is he believes that by the time [P]hase 2 rolls around, we’ll already have a bustling layer 2 ecosystem which optimistic rollups will be a big part of,” wrote Anthony Sassano, SetProtocol product marketing manager and author of the Ethereum-focused newsletter The Daily Gwei. “Basically, the network effects will be too strong and we may have wasted research and development effort on [P]hase 2 instead of focusing on phase 1 and 1.5.”

Backing Buterin’s proposal, Sassano appended:

“Imagine that the base-layer of Ethereum becomes an ultra-decentralized and ultra-secure layer for these layer 2 constructions to settle on while end-users get to experience similar security guarantees but with ultra-low fees and near-instant transactions on layer 2.”

While, as per dapp data aggregator and analysis firm DappRadar, “Ethereum stands as the most significant blockchain even given the gas price jump” thanks to the recent DeFi and DEX dapp categories explosion, as well as the yield farming in combination with interest in governance tokens. “While some anticipated Ethereum 2.0’s release, others joined the hype regardless of the high Ethereum gas prices,” it said.

There was also a 154% increase when looking at daily active wallets. DeFi and DEX categories together went up from 12,800 everyday active wallets to 50,200 in Q3 2020. In Q3, DeFi became the largest ecosystem in Ethereum, holding 90% of total daily active wallets. 74% of the DeFi ecosystem’s everyday active wallets belong to the Uniswap decentralized exchange, which grew 560% quarter-on-quarter. Balancer (BAL) with 1,100 daily active wallets is in second place, and SushiSwap with around 984 everyday active wallets in the third.

While Ethereum 2.0 developers were hard at work launching testnets this year before the Phase 0 arrival. The most up-to-date one is Medalla, followed by the parallel-running, short-term Spadina. Both have experienced issues, and with Medalla having stabilized, different short-term testnet will succeed Spadina, called Zinken. The bugs are getting fixed, and they’re getting scantier each time, Buterin stated in his presentation:
