The idea of modular blockchains is turning into the brand new narrative for community scalability and blockchain infrastructure.
The following evolution of the blockchain permits for designing precept separation of issues to scale throughput. This may be performed whereas making certain the community is trustless and decentralized. Modular blockchains can break the connection between computation and verification prices.
Earlier this month, Volt Capital performed an in-depth evaluation of modular blockchains. Their deep dive is past the scope of this text so we are going to cowl the fundamentals.

Evolution of Blockchains
The researchers famous that the core parts of a Layer 1 blockchain may be damaged up. Moreover, the result’s an enormous enchancment in particular person layers. A extra scalable, composable, and decentralized system is the ultimate aim.
Blockchains have the scalability trilemma. Which means a compromise on decentralization, safety, or scalability can present robust properties for the opposite two. It is vitally onerous to realize all three with out compromising one among them.
Fault proofs can be utilized to resolve decentralized block validation. Splitting blockchain nodes into full nodes and light-weight purchasers is one possibility. These gentle purchasers can then depend on fault proofs generated by full nodes for transaction validation.
Moreover, the sunshine purchasers must assume transactions are legitimate with out having to obtain the complete block. That is achieved with Optimistic rollups. It will also be achieved by way of a mathematical primitive referred to as erasure coding.
Erasure coding can carry out information availability sampling, permitting gentle purchasers to confirm the information with out downloading the block.
Validity proofs and zero-knowledge rollups may also obtain decentralized block validation. That is carried out by stripping away a few of the transaction information for state transitions.
Nevertheless, there was some pushback resulting from safety issues. Extra belief issues are additionally raised with a fragmented settlement and information availability layer, the researchers famous.
Software Chains
Blockchains are evolving in the same solution to net infrastructure. Information has moved from centralized server storage to distributed cloud storage. “The decentralized net is evolving from monolithic blockchains and siloed consensus layers to modular, application-specific chains with shared consensus layers,” the researchers acknowledged.
Avalanche and Polygon are two networks already utilizing application-specific chains or app-chains. They’re referred to as subnets and supernets and had been reviewed by Altcoin Buzz earlier this week.
