Enum opentimestamps::attestation::Attestation

pub enum Attestation {
    Bitcoin {
        height: usize,
    },
    Pending {
        uri: String,
    },
    Unknown {
        tag: Vec<u8>,
        data: Vec<u8>,
    },
}

An attestation that some data existed at some time

Variants

Bitcoin

An attestation from a Bitcoin blockheader. This consists of a blockheight and nothing more, it is expected that the current hash is equal to the Merkle root of the block at this height.

Fields of Bitcoin

height: usize

Pending

An attestation from some server. It is commented at length in Peter Todd's python-opentimestamps that the server should be expected to keep anything it attests to, forever, and therefore the only thing we store locally is a single simple URI with a very restricted charset. (The restricted charset seems mainly to be to avoid the software being used for nefarious purposes, as it will fetch this URI under some circumstances.)

Fields of Pending

uri: String

Unknown

An unknown attestation that we just store straight

Fields of Unknown

tag: Vec<u8>data: Vec<u8>
