[−][src]Struct grin_core::core::transaction::Output
Output for a transaction, defining the new ownership of coins that are being transferred. The commitment is a blinded value for the output while the range proof guarantees the commitment includes a positive value without overflow and the ownership of the private key. The switch commitment hash provides future-proofing against quantum-based attacks, as well as providing wallet implementations with a way to identify their outputs for wallet reconstruction.
Fields
features: OutputFeatures
Options for an output's structure or use
commit: Commitment
The homomorphic commitment representing the output amount
proof: RangeProof
A proof that the commitment is in the right range
Methods
impl Output
[src]

commits: &Vec<Commitment>,
proofs: &Vec<RangeProof>

Trait Implementations
impl Writeable for Output
[src]
Implementation of Writeable for a transaction Output, defines how to write an Output as binary.
impl Readable for Output
[src]
Implementation of Readable for a transaction Output, defines how to read an Output from a binary stream.
impl PMMRable for Output
[src]
We can build an Output MMR but store instances of OutputIdentifier in the MMR data file.
type E = OutputIdentifier
The type of element actually stored in the MMR data file. This allows us to store Hash elements in the header MMR for variable size BlockHeaders. Read more

fn short_id(&Self, &Hash, u64) -> ShortId
[src]
Generate a short_id via the following -
- extract k0/k1 from block_hash hashed with the nonce (first two u64
values) * initialize a siphasher24 with k0/k1
- self.hash() passing in the siphasher24 instance
- drop the 2 most significant bytes (to return a 6 byte short_id)
