Crate griffin_core 

This crate contains all the fundamental building blocks for the Griffin ledger, runtime, and wallet.

It was initially based on tuxedo_core, and it now includes a clone of six crates from the Pallas suite, with modifications in order to be used in a no-std setting.

The Core main purpose is to bring the Griffin node to life. The node is based on Substrate / Polkadot SDK, and the instructions to make it run can be found here.

Modules

checks_interface

Suplementary functions to perform ledger checks on Griffin transactions by using tools available in Pallas.

genesis

Utilities for blockchainchain genesis.

h224

Implementation of Polkadot-friendly 28-byte hash H224

pallas_addresses

(Brought from the Pallas suite, no-std version.)

pallas_applying

(Brought from the Pallas suite, no-std version.)

pallas_codec

(Brought from the Pallas suite, no-std version.)

pallas_crypto

pallas_interface

Interface between Griffin and Pallas Transaction types.

pallas_primitives

(Brought from the Pallas suite, no-std version.)

pallas_traverse

support_macros

These macros were copied from frame-support.

types

Types used to construct Griffin transactions.

uplc

utxo_set

UTxO interface to storage.

Macros

ensure

Evaluate $x:expr and if not true return Err($y:expr).

fail

Return Err of the expression: return Err($expression);.

Structs

Constants

EXTRINSIC_KEY

A transient storage key that will hold the list of extrinsics that have been applied so far. This key is cleared before the end of the block.

HEIGHT_KEY

A storage key that will store the block height during and after execution. This allows the block number to be available in the runtime even during off-chain api calls.

MILLI_SECS_PER_SLOT

The Aura slot duration. When things are working well, this will also be the block time.

ZERO_SLOT

A storage key that will store the slot number of the first block in the chain.

ZERO_TIME

A storage key that will store the start POSIX time of ZERO_SLOT, in milliseconds.
