Smart contracts in a blockchain change everything
summary
Titles claim transformation but specifics decide: King of the Ether lost payouts when a send to an address fails due to underestimated gas and lacks error handling; DAO drained ~$3M of $150M leading to hard fork when recursive calls bypassed accounting; contracts with growing arrays hit execution limits so gas-limit bug locks funds permanently; mitigations include proxies, separating logic and data, unit tests and test chains, and permissioned fabrics like Hyperledger Fabric offers alterable consensus for business cases.
