Classes | |
class | CBlockFileInfo |
class | CBlockIndex |
The block chain is a tree shaped structure starting with the genesis block at the root, with each block potentially having multiple candidates to be the next block. More... | |
class | CDiskBlockIndex |
Used to marshal pointers into hashes for db storage. More... | |
class | CChain |
An in-memory indexed chain of blocks. More... | |

arith_uint256 | GetBlockProof (const CBlockIndex &block) |
int64_t | GetBlockProofEquivalentTime (const CBlockIndex &to, const CBlockIndex &from, const CBlockIndex &tip, const Consensus::Params &) |
Return the time it would take to redo the work difference between from and to, assuming the current hashrate corresponds to the difficulty at tip, in seconds. More... | |
const CBlockIndex * | LastCommonAncestor (const CBlockIndex *pa, const CBlockIndex *pb) |
Find the forking point between two chain tips. More... | |
CBlockLocator | GetLocator (const CBlockIndex *index) |
Get a locator for a block index entry. More... | |
std::vector< uint256 > | LocatorEntries (const CBlockIndex *index) |
Construct a list of hash entries to put in a locator. More... | |
Variables | |
static constexpr int64_t | MAX_FUTURE_BLOCK_TIME = 2 * 60 * 60 |
Maximum amount of time that a block timestamp is allowed to exceed the current network-adjusted time before the block will be accepted. More... | |
static constexpr int64_t | TIMESTAMP_WINDOW = MAX_FUTURE_BLOCK_TIME |
Timestamp window used as a grace period by code that compares external timestamps (such as timestamps passed to RPCs, or wallet key creation times) to block timestamps. More... | |
static constexpr int64_t | MAX_BLOCK_TIME_GAP = 90 * 60 |
Maximum gap between node time and block time used for the "Catching up..." mode in GUI. More... | |
enum BlockStatus : uint32_t |
Enumerator | |
---|---|
BLOCK_VALID_UNKNOWN | Unused. |
BLOCK_VALID_RESERVED | Reserved (was BLOCK_VALID_HEADER). |
BLOCK_VALID_TREE | All parent headers found, difficulty matches, timestamp >= median previous, checkpoint. Implies all parents are also at least TREE. |
BLOCK_VALID_TRANSACTIONS | Only first tx is coinbase, 2 <= coinbase input script length <= 100, transactions valid, no duplicate txids, sigops, size, merkle root. Implies all parents are at least TREE but not necessarily TRANSACTIONS. When all parent blocks also have TRANSACTIONS, CBlockIndex::nChainTx will be set. |
BLOCK_VALID_CHAIN | Outputs do not overspend inputs, no double spends, coinbase output ok, no immature coinbase spends, BIP30. Implies all parents are either at least VALID_CHAIN, or are ASSUMED_VALID |
BLOCK_VALID_SCRIPTS | Scripts & signatures ok. Implies all parents are either at least VALID_SCRIPTS, or are ASSUMED_VALID. |
BLOCK_VALID_MASK | All validity bits. |
BLOCK_HAVE_DATA | full block available in blk*.dat |
BLOCK_HAVE_UNDO | undo data available in rev*.dat |
BLOCK_HAVE_MASK | |
BLOCK_FAILED_VALID | stage after last reached validness failed |
BLOCK_FAILED_CHILD | descends from failed block |
BLOCK_FAILED_MASK | |
BLOCK_OPT_WITNESS | block data in blk*.dat was received with a witness-enforcing client |
BLOCK_ASSUMED_VALID | If ASSUMED_VALID is set, it means that this block has not been validated and has validity status less than VALID_SCRIPTS. Also that it may have descendant blocks with VALID_SCRIPTS set, because they can be validated based on an assumeutxo snapshot. When an assumeutxo snapshot is loaded, the ASSUMED_VALID flag is added to unvalidated blocks at the snapshot height and below. Then, as the background validation progresses, and these blocks are validated, the ASSUMED_VALID flags are removed. See This flag is only used to implement checks in CheckBlockIndex() and should not be used elsewhere. |
