to a proposal to switch to using sqlite) :.Databases sometimes have errors which cause them to fail to return records, or to return stale data. Note that the LevelDB's are redundant in the sense that they can be rebuilt from the block data. The wrapper is instantiated in a global variable called pblocktree, defined in main. Enter /Library into the box and press enter. "mapBlockIndex" is an unordered_map that holds CBlockIndex for each block in the entire block tree; not just the active chain. (See here: Sipa comment on PR 6102 ) The FlushStateToDisk code is well-commented so for more info, the curious reader can check main. It contains a cache and sets its backend to be the mempool view. The block index database cares not for such details, since it holds only the metadata for the block. ChainActive (vector CBlockIndex* chainActive is the holy blockchain.

Block index (leveldb the block index holds metadata about all known blocks, including where the block is stored on disk. Looks up the spent coins Un-spends the coins in a helper function, ApplyTxInUndo: coins- voutout. This allows recovery of the original data directory in case something goes wrong.

More info about block files, see here: the commit that puts multiple blocks in a block file (2012). Creation in code: Its lifetime is also that of AcceptToMemoryPool in main. Instead, getrawtransaction uses the coin database to find the block height, and then scans that block to find the requested transaction. Bitcoin Mining genannt wird, beschreibt die Schaffung neuer Blöcke in der Bitcoin Blockchain. MapBlocksUnlinked B,C Upon receiving block B, we can connect. If there's a problem with one of the block's transactions, the block is not connected, and the code punishes the peer that sent us the bad block. DisconnectTip does the following: Returns the utxo's that were consumed by this block back to the utxo set (DisconnectBlock). It is these users who keep Bitcoin decentralized. Store C to disk and keep it in mapBlocksIndex - it's a known block Discard D (do not store to disk) and delete it from mapBlocksIndex - it's a bad block Remove D from setBlockIndexCandidates Now our chainActive is Genesis A-B, and setBlockIndexCandidates is empty. Cpp:2231 : CCoinsViewCache view(pcoinsTip Mempool view ViewMemPool pCoinsTip This object brings the mempool into view, meaning it can see both a utxo set and the mempool. It's set initially when loading the block index, and updated when adding a header to the mapBlockIndex which has more work than the current pIndexBestHeader. Manipulationen wird hier vorgebeugt, indem die Werte (.

A provably unspendable coin can be eliminated from the utxo database regardless of its amount. See LoadBlockIndexGuts in src/txdb.
