Detailed Description
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. A blockindex may have multiple pprev pointing to it, but at most one of them can be part of the currently active branch.

inline |
Check whether this block's and all previous blocks' transactions have been downloaded (and stored to disk) at some point.
Does not imply the transactions are consensus-valid (ConnectTip might fail) Does not imply the transactions are still stored on disk. (IsBlockPruned might return true)
◆ IsValid()
|
inline |
Check whether this block index entry is valid up to the passed validity level.
◆ RaiseValidity()
|
inline |
Raise the validity level of this block index entry. Returns true if the validity was changed.

Member Data Documentation
◆ hashMerkleRoot
| uint256 CBlockIndex::hashMerkleRoot |
◆ nBits
| uint32_t CBlockIndex::nBits |
◆ nChainTx
| unsigned int CBlockIndex::nChainTx |
(memory only) Number of transactions in the chain up to and including this block. This value will be non-zero only if and only if transactions for this block and all its parents are available. Change to 64-bit type when necessary; won't happen before 2030
◆ nChainWork
| arith_uint256 CBlockIndex::nChainWork |
(memory only) Total amount of work (expected number of hashes) in the chain up to and including this block
◆ nDataPos
| unsigned int CBlockIndex::nDataPos |
Byte offset within blk?????.dat where this block's data is stored.
◆ nFile
| int CBlockIndex::nFile |
Which # file this block is stored in (blk?????.dat)
◆ nHeight
| int CBlockIndex::nHeight |
height of the entry in the chain. The genesis block has height 0
◆ nMedianTimeSpan
|
static |
◆ nNonce
| uint32_t CBlockIndex::nNonce |
◆ nSequenceId
| int32_t CBlockIndex::nSequenceId |
(memory only) Sequential id assigned to distinguish order in which blocks are received.
◆ nStatus
| uint32_t CBlockIndex::nStatus |
Verification status of this block. See enum BlockStatus.
◆ nTime
| uint32_t CBlockIndex::nTime |
◆ nTimeMax
| unsigned int CBlockIndex::nTimeMax |
(memory only) Maximum nTime in the chain up to and including this block.
◆ nTx
| unsigned int CBlockIndex::nTx |
Number of transactions in this block. Note: in a potential headers-first mode, this number cannot be relied upon
◆ nUndoPos
| unsigned int CBlockIndex::nUndoPos |
Byte offset within rev?????.dat where this block's undo data is stored.
◆ nVersion
| int32_t CBlockIndex::nVersion |
block header
◆ phashBlock
| const uint256* CBlockIndex::phashBlock |
pointer to the hash of the block, if any. Memory is owned by this CBlockIndex
◆ pprev
| CBlockIndex* CBlockIndex::pprev |
pointer to the index of the predecessor of this block
◆ pskip
| CBlockIndex* CBlockIndex::pskip |
pointer to the index of some further predecessor of this block
