ChainConfig is the core config which determines the blockchain settings.
ChainConfig is stored in the database on a per block basis. This means that any network, identified by its genesis block, can have its own set of configuration options.

func (*ChainConfig) IsPetersburg ¶
func (c *ChainConfig) IsPetersburg(num *big.Int) bool

func (*ChainConfig) Rules ¶
func (c *ChainConfig) Rules(num *big.Int) Rules
Rules ensures c's ChainID is not nil.
func (*ChainConfig) String ¶
func (c *ChainConfig) String() string
String implements the fmt.Stringer interface.
type CheckpointOracleConfig ¶
type CheckpointOracleConfig struct { Address common.Address `json:"address"` Signers []common.Address `json:"signers"` Threshold uint64 `json:"threshold"` }
CheckpointOracleConfig represents a set of checkpoint contract(which acts as an oracle) config which used for light client checkpoint syncing.
type CliqueConfig ¶
type CliqueConfig struct { Period uint64 `json:"period"` // Number of seconds between blocks to enforce Epoch uint64 `json:"epoch"` // Epoch length to reset votes and checkpoint }
CliqueConfig is the consensus engine configs for proof-of-authority based sealing.
func (*CliqueConfig) String ¶
func (c *CliqueConfig) String() string
String implements the stringer interface, returning the consensus engine details.
type ConfigCompatError ¶
type ConfigCompatError struct { What string // block numbers of the stored and new configurations StoredConfig, NewConfig *big.Int // the block number to which the local chain must be rewound to correct the error RewindTo uint64 }
ConfigCompatError is raised if the locally-stored blockchain is initialised with a ChainConfig that would alter the past.
func (*ConfigCompatError) Error ¶

type Rules ¶
type Rules struct { ChainID *big.Int IsHomestead, IsEIP150, IsEIP155, IsEIP158 bool IsByzantium, IsConstantinople, IsPetersburg, IsIstanbul bool IsBerlin bool }
Rules wraps ChainConfig and is merely syntactic sugar or can be used for functions that do not have or require information about the block.
Rules is a one time interface meaning that it shouldn't be used in between transition phases.
type TrustedCheckpoint ¶
type TrustedCheckpoint struct { SectionIndex uint64 `json:"sectionIndex"` SectionHead common.Hash `json:"sectionHead"` CHTRoot common.Hash `json:"chtRoot"` BloomRoot common.Hash `json:"bloomRoot"` }
TrustedCheckpoint represents a set of post-processed trie roots (CHT and BloomTrie) associated with the appropriate section index and head hash. It is used to start light syncing from this checkpoint and avoid downloading the entire header chain while still being able to securely access old headers/logs.
func (*TrustedCheckpoint) Empty ¶
func (c *TrustedCheckpoint) Empty() bool
Empty returns an indicator whether the checkpoint is regarded as empty.
func (*TrustedCheckpoint) Hash ¶
func (c *TrustedCheckpoint) Hash() common.Hash
Hash returns the hash of checkpoint's four key fields(index, sectionHead, chtRoot and bloomTrieRoot).
