Module grin_core::global

Values that should be shared across all modules, without necessarily having to pass them all over the place, but aren't consensus values. should be used sparingly.

Structs

CHAIN_TYPE	The mining parameter mode
POW_CONTEXT_TYPE	PoW context type to instantiate

Enums

ChainTypes	Types of chain a server can run with, dictates the genesis block and and mining parameters used.
PoWContextTypes	PoW test mining and verifier context

Constants

AUTOMATED_TESTING_COINBASE_MATURITY	Automated testing coinbase maturity
AUTOMATED_TESTING_MIN_EDGE_BITS	Define these here, as they should be developer-set, not really tweakable by users Automated testing edge_bits
AUTOMATED_TESTING_PROOF_SIZE	Automated testing proof size
COMPACTION_CHECK	Trigger compaction check on average every day for all nodes. Randomized per node - roll the dice on every block to decide. Will compact the txhashset to remove pruned data. Will also remove old blocks and associated data from the database. For a node configured as "archival_mode = true" only the txhashset will be compacted.
PEER_EXPIRATION_REMOVE_TIME	Constant that expresses defunct peer timeout in seconds to be used in checks.
STUCK_PEER_KICK_TIME	If a peer's last updated difficulty is 2 hours ago and its difficulty's lower than ours, we're sure this peer is a stuck node, and we will kick out such kind of stuck peers.
TESTING_CUT_THROUGH_HORIZON	Testing cut through horizon in blocks
TESTING_INITIAL_DIFFICULTY	Testing initial block difficulty
TESTING_INITIAL_GRAPH_WEIGHT	Testing initial graph weight
TESTING_MAX_BLOCK_WEIGHT	Testing max_block_weight (artifically low, just enough to support a few txs).
TESTING_STATE_SYNC_THRESHOLD	Testing state sync threshold in blocks
USER_TESTING_COINBASE_MATURITY	User testing coinbase maturity
USER_TESTING_MIN_EDGE_BITS	User testing edge_bits
USER_TESTING_PROOF_SIZE	User testing proof size

Functions

base_edge_bits	Reference edge_bits used to compute factor on higher Cuck(at)oo graph sizes, while the min_edge_bits can be changed on a soft fork, changing base_edge_bits is a hard fork.
chain_shortname	Short name representing the current chain type ("floo", "main", etc.)
coinbase_maturity	Coinbase maturity for coinbases to be spent
create_pow_context	Return either a cuckoo context or a cuckatoo context Single change point
cut_through_horizon	Horizon at which we can cut-through and do full local pruning
difficulty_data_to_vector	Converts an iterator of block difficulty data to more a more manageable vector and pads if needed (which will) only be needed for the first few blocks after genesis
get_genesis_nonce	Helper function to get a nonce known to create a valid POW on the genesis block, to prevent it taking ages. Should be fine for now as the genesis block POW solution turns out to be the same for every new block chain at the moment
initial_block_difficulty	Initial mining difficulty
initial_graph_weight	Initial mining secondary scale
is_automated_testing_mode	Are we in automated testing mode?
is_floonet	Are we in floonet? Note: We do not have a corresponding is_mainnet() as we want any tests to be as close as possible to "mainnet" configuration as possible. We want to avoid missing any mainnet only code paths.
is_mainnet	Are we for real?
is_production_mode	Are we in production mode? Production defined as a live public network, testnet[n] or mainnet.
is_user_testing_mode	Are we in user testing mode?
max_block_weight	Maximum allowed block weight.
min_edge_bits	The minimum acceptable edge_bits
proofsize	The proofsize
set_mining_mode	Set the mining mode
state_sync_threshold	Threshold at which we can request a txhashset (and full blocks from)
