Required Methods

fn build_block<'life0, 'async_trait>(
    &'life0 self
) -> Pin<Box<dyn Future<Output = Result<Box<dyn Block + Send + Sync>>> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

Attempt to create a new block from ChainVm data Returns either a block or an error

fn issue_tx<'life0, 'async_trait>(
    &'life0 self
) -> Pin<Box<dyn Future<Output = Result<Box<dyn Block + Send + Sync>>> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

Issues a transaction to the chain

fn set_preference<'life0, 'async_trait>(
    &'life0 self,
    id: Id
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

Notify the Vm of the currently preferred block.

fn last_accepted<'life0, 'async_trait>(
    &'life0 self
) -> Pin<Box<dyn Future<Output = Result<Id>> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

Returns the ID of the last accepted block. If no blocks have been accepted, this should return the genesis block
