🧵on the lay of the modular blockchain land for @scribeDAO
TL:DR; Blockchains have now become composable removing the need for a singular chain to tackle the Blockchain trilemma, rather a variety of chains can specialize and work together as modules to provide the best solution
This article discusses the three main components of blockchains, and how now a variety of chains can specialize and come together to more efficiently tackle the trilemma

🅰️What is a blockchain fundamentally?
A gross oversimplification, but you can bucket a blockchain into 3 main functionalities
Execution
Security
Data Availability
A singular blockchain having to complete all three is what leads to the trilemma, but they can be split apart
1⃣ Execution
We can have execution exclusive layers solely focused on throughput
Rollups are the best example of this, with ORs like A1
However, we are fast improving even here with EVM compatible volitions like zkSync 2.0 and StarkNet v1 that will reduce tx fees to ~$.0X
2⃣ Security
Here we can rely upon our ultra secure L1s ETH and BTC
Other L1s have unfortunately made sacrifices here to security/decentralization to achieve scalability
And unless BTC adds verification capability to zk-SN(T)ARKs, even they cannot compete with ETH here
3⃣ Data Availability
ETH 2.0 also has a great roadmap here with sharded chains, but is not close to completion
In the meantime validiums and volitions can create separate data availability layers by committing compressed tx data while maintaining ETHs security capabilities
4⃣ Conclusion
It's clear that concept of composabilty is now being extended to blockchains. The efficiency of specialization should narrow the aperture for new blockchains to focus on execution, security, or data availability. There's no need to do it all
