😜 @arbitrum Recently, they're not only focusing on performance optimization but also putting a lot of effort into the underlying storage, with Erigon being a typical example. In the past, running a Full Node required several terabytes of hard disk space, which was unaffordable for ordinary people. Now, Erigon has lowered the storage barrier to a level where "everyone can participate."

The biggest highlight of Erigon is actually its "extreme compression." It is said that compared to the established client Geth, its storage efficiency has improved by 25 times, and the RPC performance has also increased several times. Simply put, there is still so much data, but it takes up much less space. This is very attractive for developers, community organizations, and small teams who want to run a Full Node but are limited by costs.

There is one more point that I agree with, which is that Erigon does not simply pursue low costs or resource savings, but fundamentally reduces the operational difficulty of Nodes, allowing more people to participate. This not only makes Arbitrum more cost-effective, but also more decentralized. The more Nodes there are and the wider the distribution, the more resilient the system becomes.

Now Arbitrum has three clients: Nitro, Nethermind, and Erigon. This is not just a simple "one more option", but a step towards real diversification and risk resistance. For a system to be stable, not everyone can run the same client; if something goes wrong, it's a total disaster. With these combinations, Arbitrum's foundation has really strengthened.
