Ethereum and EVM chain account address: 0x then forty hex characters. The hex class stays tolerant to case because EIP-55 carries its checksum in the capitalisation of the letters alone, so lowering the case would destroy it. Noise is low, a 0x prefix on exactly forty hex characters is specific, but the pattern also matches contract addresses, which are not personal data, and any 160-bit hash written with a 0x prefix. No collision.
