* Rewrite CreateNewBlockAlex Morcos2015-12-011-181/+120
| | | | | | | | | | Use the score index on the mempool to only add sorted txs in order. Remove much of the validation while building the block, relying on mempool to be consistent and only contain txs that can be mined. The mempool is assumed to be consistent as far as not containing txs which spend non-existent outputs or double spends, and scripts are valid. Finality of txs is still checked (except not coinbase maturity, assumed in mempool). Still TestBlockValidity in case mempool consistency breaks and return error state if an invalid block was created. Unit tests are modified to realize that invalid blocks can now be constructed if the mempool breaks its consistency assumptions and also updated to have the right fees, since the cached value is now used for block construction.

| | | | | | | | | | | | | | | | | | | | | | This switches the Merkle tree logic for blocks to one that runs in constant (small) space. The old code is moved to tests, and a new test is added that for various combinations of block sizes, transaction positions to compute a branch for, and mutations: * Verifies that the old code and new code agree for the Merkle root. * Verifies that the old code and new code agree for the Merkle branch. * Verifies that the computed Merkle branch is valid. * Verifies that mutations don't change the Merkle root. * Verifies that mutations are correctly detected.

* Restore MedianTimePast for locktime.Gregory Maxwell2015-11-031-1/+7
| | | | | | | | Revert "Revert "Add rules--presently disabled--for using GetMedianTimePast as endpoint for lock-time calculations"" This reverts commit 40cd32e835092c3158175511da5193193ec54939. After careful analysis it was determined that the change was, in fact, safe and several people were suffering momentary confusion about locktime semantics.

| | | | | | | | | | | | | endpoint for lock-time calculations" This reverts commit 9d55050773d57c0e12005e524f2e54d9e622c6e2. As noted by Luke-Jr, under some conditions this will accept transactions which are invalid by the network rules. This happens when the current block time is head of the median time past and a transaction's locktime is in the middle. This could be addressed by changing the rule to MAX(this_block_time, MTP+offset) but this solution and the particular offset used deserve some consideration.
* Add rules--presently disabled--for using GetMedianTimePast as endpoint for ↵Mark Friedenbach2015-10-231-1/+7
| | | | | | | | lock-time calculations The lock-time code currently uses CBlock::nTime as the cutoff point for time based locked transactions. This has the unfortunate outcome of creating a perverse incentive for miners to lie about the time of a block in order to collect more fees by including transactions that by wall clock determination have not yet matured. By using CBlockIndex::GetMedianTimePast from the prior block instead, the self-interested miner no longer gains from generating blocks with fraudulent timestamps. Users can compensate for this change by simply adding an hour (3600 seconds) to their time-based lock times. If enforced, this would be a soft-fork change. This commit only adds the functionality on an unexecuted code path, without changing the behaviour of Bitcoin Core.
* Do not store Merkle branches in the wallet.Pieter Wuille2015-09-221-1/+1
| | | | | | | | | | Assume that when a wallet transaction has a valid block hash and transaction position in it, the transaction is actually there. We're already trusting wallet data in a much more fundamental way anyway. To prevent backward compatibility issues, a new record is used for storing the block locator in the wallet. Old wallets will see a wallet file synchronized up to the genesis block, and rescan automatically.

* Fix crash when mining with empty keypool.Daniel Kraft2015-08-181-2/+4
| | | | | | | Since the introduction of the ScriptForMining callback, the mining functions (setgenerate and generate) crash with an assertion failure (due to a NULL pointer script returned) if the keypool is empty. Fix this by giving a proper error.
