System Architecture Diagnostics
Architecture Autopsies
We don't just build systems. We dissect why they fail in production. Explore real-world autopsies of key Web3 apps, tracing their evolution from naive designs to robust infrastructures.

ChainElect — The Naive Voting System Gas Collapse
[goal]
System Goal
Build a decentralized voting platform where election logs are immutably verified.
[prototype]
The Naive Prototype
React client calling Solidity contract functions directly via MetaMask, storing all voter addresses in a dynamic on-chain array.
[failure]
Why it broke in production
As voter count scaled to 714, the gas cost of iterating the array to count votes exceeded the Block Gas Limit. Transactions began to revert automatically, and public RPC node endpoints rate-limited the API keys.
[fix]
Production Refactoring
- Refactored storage array iteration into O(1) Solidity mapping lookups
- Packed storage variables (uint8, address, bool) in slots to save gas
- Delegated vote counting off-chain via indexer event logs
> Solidity contract storage is a consensus notary, not a database. Never loop over unbounded dynamic arrays on-chain.
