package runner

import ""

Package sebak is the node of blockchain, which implements "ISAAC" Consensus Protocol at first time. ISAAC is based on the FBA consensus protocol, but is totally different from SCP(Stellar Cosensus Protocol).

sebak is the old term of "SaeByeog" in Korean, which means dawn.

Struct that bridges together components of a node

NodeRunner bridges together the connection, storage and `LocalNode`. In this regard, it can be seen as a single node, and is used as such in unit tests.

Validate an operation

This function is critical for consensus, as it defines the validation rules for an operation, and by extension a transaction. It is called from ValidateTx.


st = Storage backend to use (e.g. to access the blocks)
     Only ever read from, never written to.
config = consist of configuration of the network. common address, congress address, etc.
source = Account from where the transaction (and ops) come from
tx = Transaction to check

func ValidateTx Uses

func ValidateTx(st *storage.LevelDBBackend, config common.Config, tx transaction.Transaction) (err error)

Validate the entirety of a transaction

This function is critical for consensus, as it defines the validation rules for a transaction. It is executed whenever a transaction is received.

As it is run on every single transaction, it should be as fast as possible, thus any new code should carefully consider when it takes place. Consider putting cheap, frequent errors first.

Note that if we get to this function, it means the transaction is known to be well-formed (e.g. the signature is legit).
