description	Shared reference for the blockchain-web3 cluster: the adversarial on-chain threat model (immutable, anyone-can-call, MEV), checks-effects-interactions, oracle-manipulation resistance, token-decimals precision, and the non-advisory stance for trading/prediction-market work. USE WHEN writing, auditing, or reasoning about smart-contract / DeFi / on-chain code — the cross-cutting model every web3 spoke shares.

Blockchain / Web3 Core

Shared model for the blockchain-web3 cluster. On-chain code is immutable, public, and adversarial — once deployed, anyone can call it, read its state, and reorder/observe its transactions. That single fact drives every rule below.

1. The adversarial model (decide everything from here)

• Anyone can call any external function in any order, any number of times. Never assume a caller, a sequence, or a single invocation.
• Everything on-chain is public — "private" variables are readable; no secrets in contract state.
• Transactions are front-runnable / reorderable (MEV) — the mempool is visible; assume an adversary can sandwich, front-run, or back-run any state-changing call.
