Ronin’s decision to migrate back to Ethereum as a full Layer 2 network raises a big question: Are standalone blockchains losing ground to Ethereum’s growing Layer 2 ecosystem? As Ethereum upgrades improve speed and reduce costs, sidechains are becoming increasingly difficult to ignore.
Key Takeaways
-
Ronin returns to Ethereum as Layer 2, citing security, scalability and cost improvements.
-
Sidechains face increasing pressure as Ethereum Layer 2 networks mature and attract institutional adoption.
-
Immutable X and Polygon remain strong players in gaming, but face competition from Ethereum’s scaling roadmap.
-
Ronin’s Proof-of-Distribution model shifts incentives from validators to active builders.
-
Security incidents on Ronin highlight the risks of running independent sidechains.
Why Ronin Returns to Ethereum
Ronin started as a gaming sidechain for Axie Infinity, offering low fees and fast transactions when Ethereum had limitations. After Ethereum 2.0 upgrades As transactions became cheaper and more efficient, Ronin found it made more sense to become an Ethereum Layer 2.
By going back, Ronin inherits Ethereum’s decentralization, institutional momentum, and security model. It also distances itself from previous exploits, including the $625 Million Hack by 2022 and the $12 million 2024 exploit, which exposed the vulnerabilities of smaller sidechains.
Immutable X: Promise vs. Plateau
Immutable intended to be the best platform for NFTs and gamingusing zero-knowledge combinations. The technology works well, but actual adoption has not matched the initial excitement. Aside from a few major partnerships, growth in gaming has slowed. The goal of becoming the premier gaming chain has not succeeded on the scale many had hoped.
A challenge for Immutable X is its limited focus. By focusing on NFTs and gaming, it tied its growth to markets that can be unpredictable. As the play-to-earn trend faded, there were fewer big games to keep activity up, and smaller developers weren’t joining in as quickly. Without more use cases or a larger developer base, Immutable X could end up as a niche platform instead of a top Layer 2 option.
Polygon: versatility or fragmentation?
Polygon positioned itself as a versatile scaling solution that offers everything from proof-of-stake chains to zk rollups. At first glance, this range suggests adaptability, but in practice it can create more noise than clarity.
Much of Polygon’s momentum has been fueled by incentives, subsidies and aggressive marketing campaigns, rather than deep, organic developer involvement. While important partnerships are attracting attention, questions remain about how much of that activity translates into long-term sustainable use.
The biggest risk for Polygon is trying to do too much at once. This can cloud its focus and make developers unsure about which products will last. In this case, versatility may even make it harder for Polygon to become a leader in any one area.
Ethereum’s upgrades are game changing
Ethereum’s move to Proof of stake and recent scaling updates have changed things. Gas rates, which used to push projects to side chains, have fallen and the network can now handle more transactions.
Now developers and investors no longer have to choose between costs and security. Instead of running separate chains, projects can leverage Ethereum’s strong infrastructure and take advantage of its large pool of liquidity and developers.
New tokenomics and incentives
One of the more interesting aspects of Ronin’s transition is the new Proof-of-Distribution model. Instead of rewarding validators, Ronin will hand out incentives to developers, liquidity providers, and other contributors.
This approach is intended to support real growth in the ecosystem. It also shows that the future is not just about keeping chains safe, but about rewarding the people who help build and maintain these communities.
Safety as a decisive factor
Security is still the biggest weakness for sidechains. The big Ronin hack of 2022 was a wake-up call for the entire industry. By moving to Ethereum’s Layer 2, Ronin reduces the risk of bridge attacks and other minor chain problems.
For projects considering their next steps, this migration is a reminder that trust and security are just as important as performance.
Is abandoning sidechains the future?
Ronin’s return to Ethereum suggests that abandoning sidechains could become a trend, especially as Ethereum continues to grow in strength. While networks like Immutable X and Polygon still hold unique positions, the market appears to be consolidating around Ethereum’s scalable ecosystem.
For developers, this shift is an opportunity to build on infrastructure that balances cost, speed and security. For investors, it is a sign that Ethereum’s influence is not decreasing, but growing stronger.
