ICO protocols & implementations
summary
Covers concrete smart‑contract patterns in Solidity with OpenZeppelin primitives and a GitHub repo, shows simple uncapped and capped implementations and why they fail (uncertainty of valuation, network congestion, whale fee wars), and presents deployed alternatives: reverse Dutch auction where token percentage sold rises per block, Basic Attention Token example: $35M sale with 135 successful vs ~10,000 failed txs and ~70 ETH lost to fees, and Gnosis: ~5% sold day one, 90% lock, implied $250M valuation; notes gas limits make interactive ICOs hard to implement.
