We all know that the main selling point of L2s networks on Ethereum is that theyHuge benefits to users in terms of scalability, although I think this underestimates the utility L2s bring. This is because they also provide other important features such asNear-instant transaction confirmation, allowing for richer development efforts(not limited to Solidity and EVM), and best of all,image description

So, what exactly does it mean to “outsource security to Ethereum”? In simple terms, this meansL2s structures don't have to worry about needing consensus on the transactions they process and execute because they outsource this work to Ethereum L1 to do it!This is what I often call "modular design", that is, in the modular design stack of Ethereum,L2s are the execution/computation layer, while Ethereum L1 is the consensus/security layer and (optionally) the data availability layer(Note: The L2s network will selectively use Ethereum L1 as the data availability layer, such as the Rollups network; while the Validium solution chooses to put data availability off the chain).

Of course, over time,L2s networks will need to decentralize their sequencers and validatorstherefore,

therefore,I think the era of L1s is over, going forward, we will likely not see any more L1 networks being deployed; instead, we will only see blockchains built purely for data availability, such as Celestia and Polygon Avail; we may see to some one-off L1s deployments that end up being worthless. I believe,The next few years will be dominated by L2s networks that leverage the security, community, and network effects of Ethereum's L1, enabling their own rapid usage growth and adoption.The beauty of this approach is that L2s networks don't have to worry about consensus/security layers at all, all they need to do is pay Ethereum L1 for gas to store proofs and/or data, thus providing security for themselves Guaranteed so that they can focus all their attention on improving their own execution/computational processes.

A popular idea right now is that other L1s networks will eventually transform into L2 networks on Ethereum because it makes more sense.Now, while I agree with this, I very much doubt that those larger L1s ecosystems would consider doing this, after all they are pure ethereum competitors, and if they convert to L2s networks in ethereum, then they Basically admitting defeat to Ethereum. It would be as if the king of a rival nation had given up his crown and sworn allegiance to a new king - which is unlikely to happen (at least they are reluctant to do so).

technical leveltechnical levelonsocial levelThe same is true for Ethereum: by transitioning to an L2 network on Ethereum, they can not only continue to retain their native tokens, community, applications, etc., but also benefit from the entire Ethereum ecosystem, while not having to worry about the consensus/security layer .

Some readers here may think that I am leaning too much towards the "Ethereum maximalist" point of view, but I just think that my overview in this article is the most pragmatic view. If the goal of an L1 network is to be as decentralized and secure as possible, why not leverage otherThe most decentralized and secure blockchaincertainly,

certainly,social levelis another important factor, and this is what Ethereum's competitors like to brag about being "better" than Ethereum. If it becomes an L2 network on Ethereum, then it is equivalent to giving up this marketing point, and may hurt the value growth of their native tokens, so I can understand why they want to continue to be an L1s network (although I think This strategy is now ineffective).

I'm really looking forward to seeing which L1 network will be converted to L2 first in the future, although I can't point to any candidates yet in this regard. There are currently many smaller L1s networks that might do this, but in practice if they convert to L2 networks, they will need to compete with both native L2s networks and some larger L1s networks, so it may be possible for them It's not worth it. anyway,The next few years are going to be very interesting, and the age of L2 has really arrived.
