Consulting on Blockchain Selection for a Project
Choosing a blockchain is one of the key architectural decisions with long-term consequences. Moving from one blockchain to another after launch is a complete redeploy, user migration, and loss of accumulated state. This decision should be made consciously.
Main Selection Criteria
Security: how decentralized and battle-tested is the network? Ethereum mainnet — maximum security. New L1s — higher risk.
Cost: gas fees for end users. Mainnet Ethereum — $5-100+ per transaction. L2s (Arbitrum, Base) — $0.01-0.5. Solana — $0.001.
Speed: time to finality. Ethereum — 12 second slot, ~2 minutes economic finality. Solana — 400ms. TON — 5 seconds.
Ecosystem: TVL, developer tools, wallet support, DeFi composability.
TPS / Throughput: for high-load applications (gaming, perp DEX).
Selection Matrix
| Use Case | Recommendation | Why |
|---|---|---|
| DeFi protocol with TVL > $10M | Ethereum or Arbitrum | Security + composability |
| NFT collection | Base or Polygon | Low mint gas, good marketplaces |
| GameFi | Arbitrum or Ronin | TPS + gas cost |
| Telegram mini app | TON | Native audience 900M |
| Micro-transactions | Solana | $0.001 fee |
| Enterprise / permissioned | Polygon CDK or Hyperledger | Privacy + compliance |
Quick Decision Framework
Do you have composability requirements with existing DeFi? → Ethereum/Arbitrum/Base (EVM)
Is your main audience in Telegram? → TON
Do you need < $0.01 gas and < 1s finality? → Solana
Do you need maximum security and accept high gas? → Ethereum mainnet
Want your own blockchain with custom consensus? → Cosmos SDK or Polygon CDK
