The Blockchain Trilemma
The central challenge for blockchain developers involves balancing three core properties:
- Security: Network defense capabilities and attack resistance
- Decentralization: Distributed nodes without single points of failure
- Scalability: Transaction throughput and demand handling
Ethereum, for example, is considered decentralized and secure but struggles to keep up with increased demand. Other networks sacrifice decentralization for speed.
Monolithic Blockchain Limitations
Monolithic chains handle all functions in a single layer:
- Data Availability
- Execution
- Consensus
- Settlement
While this approach offers simplicity, it creates trade-offs: infinite ledger growth and barriers to new node participation.
The Modular Solution
Modular blockchains decompose these functions across specialized layers. Key innovations include:
- Fraud proofs and data availability sampling enable verification at scale
- Rollups exemplify modularity, handling computation while relying on Ethereum for data availability
- Specialized data availability layers (Celestia, Polygon Avail, EigenLayer) reduce posting costs
Benefits of Modularity
- Scalability without compromising security
- Reduced overhead for launching new chains
- High flexibility and interoperability
Next-Generation Data Infrastructure
Storage Solutions
IPFS-based platforms:
- Filebase: Simplifies IPFS pinning with edge caching
- Crust Network: Adds incentive mechanisms to IPFS storage (~1,200 Petabytes capacity)
Alternative approaches:
- Kwil DB: Byzantine fault-tolerant database networks
- WeaveDB: NoSQL database on Arweave for permanent storage
Data Access
Decentralized RPC Networks:
- Pocket Network and Lava Network provide distributed RPC access
- Enable multi-layer/multi-chain request routing
Data Indexing
Subsquid aggregates on-chain and off-chain data across Layer-2s and modular chains, providing a full-stack blockchain indexing solution with specialized data lakes for efficient access.
Key Takeaway
The industry shift from monolithic to modular architecture requires sophisticated data tools. Next-gen data solutions like Subsquid are paving the way for builders to tap into the wealth of data generated across fragmented blockchain ecosystems.
