Table 2.

Features of traditional databases compared with Ethereum and the Oasis Devnet.

Features	Traditional database	Ethereum (public)	Oasis Devnet
Data read access control	Yes	No, data is public	Yes, dependent on smart contract logic
Anonymity	Yes, if host is honest	Pseudo-anonymous	Pseudo-anonymous
Cost	Fixed	Variable	Free on developer network, will be variable in production mainnet
Data privacy	Yes, if host is honest	No, data is public	Yes, dependent on smart contract logic
Data mutability	Mutable, but can be immutable via role permissions	Immutable	Devnet gets reset, but the production mainnet will be immutable
Code can be updated	Yes	Yes	Not yet. Intercontract calls are planned
Publicly verifiable	No, the public cannot verify stored procedures	Yes, the public can verify smart contract codea	Yes, the public can verify smart contract codea
Widely accessible	Yes	Yes	Yes

^aFor both Ethereum and Oasis Devnet, the smart contract source code must be made public to verify that the contract is doing what is claimed.
