Crate finality_grandpa[−][src]
Finality gadget for blockchains.
https://github.com/w3f/consensus/blob/master/pdf/grandpa.pdf
Consensus proceeds in rounds. Each round, voters will cast a prevote and precommit message.
Votes on blocks are then applied to the blockchain, being recursively applied to
blocks before them. A DAG is superimposed over the blockchain with the vote_graph logic.
Equivocation detection and vote-set management is done in the round module.
The work for actually casting votes is done in the voter module.
Modules
| bitfield |
Bitfield for handling equivocations. |
| round |
Logic for a single round of GRANDPA. |
| vote_graph |
Maintains the vote-graph of the blockchain. |
| voter |
A voter in GRANDPA. This transitions between rounds and casts votes. |
Structs
| Equivocation |
An equivocation (double-vote) in a given round. |
| Precommit |
A precommit for a block and its ancestors. |
| Prevote |
A prevote for a block and its ancestors. |
| SignedMessage |
A signed message. |
Enums
| Error | |
| Message |
A protocol message or vote. |
Traits
| Chain |
Chain context necessary for implementation of the finality gadget. |
