+ * Somehow a node minted a version of block 212937 that contained one transaction: + * a PAYMENT transaction that attempted to spend more QORT than that account had as QORT balance. + *

+ * This invalid transaction made block 212937 (rightly) invalid to several nodes, + * which refused to use that block. + * However, it seems there were no other nodes minting an alternative, valid block at that time + * and so the chain stalled for several nodes in the network. + *

+ * Additionally, the invalid block 212937 affected all new installations, regardless of whether + * they synchronized from scratch (block 1) or used an 'official release' bootstrap. + *

+ * After lengthy diagnosis, it was discovered that + * the invalid transaction seemed to rely on incorrect balances in a corrupted database. + * Copies of DB files containing the broken chain were also shared around, exacerbating the problem. + *

+ * There were three options: + *

    + *
  1. roll back the chain to last known valid block 212936 and re-mint empty blocks to current height
    2. + *
  2. keep existing chain, but apply database edits at block 212937 to allow current chain to be valid
    3. + *
  3. attempt to mint an alternative chain, retaining as many valid transactions as possible
    4. + *
+ *

+ * Option 1 was highly undesirable due to knock-on effects from wiping 700+ transactions, some of which + * might have affect cross-chain trades, although there were no cross-chain trade completed during + * the decision period. + *

+ * Option 3 was essentially a slightly better version of option 1 and rejected for similar reasons. + * Attempts at option 3 also rapidly hit cumulative problems with every replacement block due to + * differing block timestamps making some transactions, and then even some blocks themselves, invalid. + *

+ * This class is the implementation of option 2. + *

+ * The change in account balances are relatively small, see block-212937-deltas.json resource + * for actual values. These values were obtained by exporting the AccountBalances table from + * both versions of the database with chain at block 212936, and then comparing. The values were also + * tested by syncing both databases up to block 225500, re-exporting and re-comparing. + *

+ * The invalid block 212937 signature is: 2J3GVJjv...qavh6KkQ. + *

+ * The invalid transaction in block 212937 is: + *
