VersionWithMeta holds the textual version string including the metadata.
Functions ¶
func ArchiveVersion ¶
ArchiveVersion holds the textual version string used for Gocore archives. e.g. "1.8.11-dea1ce05" for stable releases, or
"1.8.13-unstable-21c059b6" for unstable releases
func VersionWithCommit ¶
Types ¶
type ChainConfig ¶
type ChainConfig struct {
NetworkID *big.Int `json:"networkId"` // networkId identifies the current chain and is used for replay protection
EWASMBlock *big.Int `json:"ewasmBlock,omitempty"` // EWASM switch block (nil = no fork, 0 = already activated)
// Various consensus engines
Cryptore *CryptoreConfig `json:"cryptore,omitempty"`
Clique *CliqueConfig `json:"clique,omitempty"`
}
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) CheckCompatible ¶
func (c *ChainConfig) CheckCompatible(newcfg *ChainConfig, height uint64) *ConfigCompatError
CheckCompatible checks whether scheduled fork transitions have been imported with a mismatching chain configuration.
func (*ChainConfig) CheckConfigForkOrder ¶
func (c *ChainConfig) CheckConfigForkOrder() error
CheckConfigForkOrder checks that we don't "skip" any forks, gocore isn't pluggable enough to guarantee that forks can be implemented in a different order than on official networks
func (*ChainConfig) IsEWASM ¶
func (c *ChainConfig) IsEWASM(num *big.Int) bool
IsEWASM returns whether num represents a block number after the EWASM fork
func (*ChainConfig) Rules ¶
func (c *ChainConfig) Rules(num *big.Int) Rules
Rules ensures c's NetworkID 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 ¶
func (err *ConfigCompatError) Error() string
type CryptoreConfig ¶
type CryptoreConfig struct{}
CryptoreConfig is the consensus engine configs for proof-of-work based sealing.
func (*CryptoreConfig) String ¶
func (c *CryptoreConfig) String() string
String implements the stringer interface, returning the consensus engine details.
type Rules ¶
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).
