EIP-1559 replaced Ethereum’s first-price fee auction with a protocol-set base fee that adjusts with demand and is burned, plus an optional priority tip. It changed the economics of an entire network through a public proposal process, and it is the clearest example of open governance producing a breaking change everyone accepted.
EIP-1559
EIP-1559 is worth reading less for its mechanics than for how it happened. A fee market used by millions was redesigned through a numbered, public, adversarially reviewed proposal, implemented by independent clients, and activated by coordinated upgrade.
- A protocol-set base fee - Adjusts per block with demand rather than being guessed by each sender.
- Burned rather than paid - The base fee leaves circulation, which changed the asset’s monetary policy as a side effect.
- Predictable inclusion - Fee estimation became a calculation rather than an auction bid.
- An open process - Specified in public, contested in public, shipped by multiple independent implementations.
For anyone arguing that API governance is bureaucratic overhead, EIP-1559 is the awkward counterexample: this is what a versioned, publicly governed breaking change looks like when it is done well. It also sharpens the finding in The State of Blockchain & Crypto APIs — the same industry that governs its protocols this carefully publishes no versioning policy, deprecation window or changelog for its own service interfaces in 56% of cases.

The State of Blockchain & Crypto APIs
Public, adversarial, multi-client governance of a breaking change — in an industry that scores 11.1 on governance for its own APIs, with 56% at zero.
