Ethereum (ETH) co-founder Vitalik Buterin all the time appears to be trying a step forward, or three. Whereas layer 2 (L2) continues to be being developed, Buterin contributed to the layer 3 (L3) dialogue, arguing that they could serve a special objective, leaving scalability to L2.

As a reminder, layer 1 is the bottom layer. Ethereum itself is an L1 chain and one of the vital extensively used blockchains as we speak. L2 options are constructed on prime of those blockchains to cut back their burden on the chain.

To this, in his weblog entry titled What sort of 3 layers make sense?Buterin ‘provides’ one other layer, writing:

“If we are able to construct a layer 2 protocol that anchors at layer 1 for safety and provides scalability on prime, then absolutely we are able to scale additional by constructing a layer 3 protocol that anchors at layer 2 for safety and provides much more scalability on prime of what?”

He warns, nonetheless, that these ideas aren’t so simple as they appear and that there’s usually one thing within the design that isn’t stackable and might solely give a “as soon as scalability increase”.

Different points can also come up, together with however not restricted to limits on knowledge availability and reliance on L1 bandwidth for emergency withdrawals.

Nevertheless, L3s aren’t Buterin’s invention, and others are additionally discussing their use. Newer concepts, such because the one proposed by the blockchain startup Starkwaresays Buterin, focus extra on assigning completely different roles to L2 and L3, fairly than simply “stacking the identical factor on prime of itself”, arguing that:

“Some type of this method might be a good suggestion, if accomplished the appropriate method.”

Whereas scaling could be relegated to L2, L3 may very well be used for:

  • customized performance, eg privateness;
  • customized scaling;
  • weak belief scaling (validiums, a scaling resolution utilizing off-chain knowledge availability and computation designed to enhance efficiency by processing transactions outdoors of the Ethereum Mainnet).

Based on Buterin, this appears “basically cheap”, however he argues that there are nonetheless some essential questions with very sophisticated solutions, akin to: is a three-tier construction the appropriate strategy to obtain these targets? The very fact is, he suggests, that lots of the features that may be assigned to the L3s may maybe be fulfilled on the stage of the L2, whereas different issues may very well be solved with a special method, present or proposed.


Subsequently, Buterin argues,

“A 3-tier scaling structure that consists of stacking the identical scaling scheme on prime of itself usually would not work properly. Summaries on prime of summaries, the place the 2 layers of summaries use the identical know-how, actually do not. Nevertheless, a three-tier structure can work the place the second tier and the third tier have completely different functions.”

And whereas it isn’t the most effective long-term resolution, validiums along with rollups “do make sense,” he mentioned. Rollups are a scalable resolution that enables the transaction to be executed off-chain. They carry out transaction execution outdoors of L1, after which knowledge is shipped to L1 the place consensus is reached.

In the meantime, the long-awaited and extremely anticipated improve to the Ethereum Merge blockchain occurred on September 15, triggering the blockchain’s transition from a proof-of-work (PoW) consensus mechanism to proof-of-stake ( PoS).

Whereas the value of the coin rose briefly within the days main as much as the occasion, within the six days following the merger, ETH fell by 18.8%. On Wednesday morning (UTC time), it’s buying and selling at $1,329, down 2% in a day and down 15.5% in every week.
