* Properly initialize confirmedHash in CSimplifiedMNListEntry
* Add consensus params for temporary hard-fork on testnet
This hard-fork is required on testnet as we have to fix a few consensus
bugs in DIP3/DIP4. It will also be required to introduce LLMQ commitments
to testnet.
* Add temporary fork-logic for testnet, which sets confirmedHash to null
...before fork activation. Otherwise we'd invalidate all DIP3 blocks on
testnet.
* Bump nTemporaryTestnetForkHeight to 273000
* Add BIP9 parameters for DIP3 deployment on testnet
* Remove autoix BIP9 deployment and reuse DIP3 deployment
* Add BIP9CheckMasternodesUpgraded to chain params
This controls if miners should check for upgraded masternodes first before
adding BIP9 bits to the block version. This only makes sense in network
where masternodes are up and running before BIP9 activation, which is not
necessarely the case in regtest and devnet.
Also refactor ComputeBlockVersion to use fCheckMasternodesUpgraded instead
of the inverse fAssumeMasternodeIsUpgraded. It is set to false by default
and only set to true in CreateNewBlock.
* Check for upgraded masternodes for DIP3 activation (only mainnet and testnet)
* Bump PROTOCOL_VERSION and DMN_PROTO_VERSION
We probably have nodes with 70211 already running on testnet.
* Allow to use low difficulty and higher block rewards for devnet
Configurable through -minimumdifficultyblocks, -highsubsidyblocks and -highsubsidyfactor
* Fix review comments
* Handle review comments
* add locktransaction rpc call
* Remove special instantsend fee for simple transactions
* Function to check if trx is simple enough to be autolocked
* Automatic lock for all received from peers simple trxes
If we get a new transaction with CInv message and it is "simple" and
is accepted in mempool, we initiate its lock. We don't lock orphan trxes
that accepted in mempool after this trx because they are locked by other
peers.
* Automatically lock simple trxes in wallet
* protocol bump for InstantSend without special fee
* Add function to detect used mempool share
* Mempool threshold for auto IX locks
* Add SPORK_16_INSTANTSEND_AUTOLOCKS spork
* Make autolocks active only when spork SPORK_16_INSTANTSEND_AUTOLOCKS is active
* BIP9 autolocks activation
* revert increasing min peer protocol version for mn rank
* move IsTrxSimple check to CTxLockRequest class
* make MAX_INPUTS_FOR_AUTO_IX private member of CTxLockRequest class
* make AUTO_IX_MEMPOOL_THRESHOLD private member of CInstantSend class
* remove locktransaction RPC call
* tests for automatic IS locks
* fix mempool threshod calculation
* bump mocktime in activate_autoix_bip9
* set node times
* no need to spam the node with gettransaction rpc requests that often
* use `spork active` instead of leaking spork logic into tests
* codestyle fixes
* add test description in comments
* fix typo
* sync test nodes more often during BIP9 activation
* Use 4th bit in BIP9 activation
* Fix comments according codestyle guide
* Call AcceptLockRequest and Vote at the first node creating autoix lock
* fix mempool used memory calculation
* rallback not necessary change in CWallet::CreateTransaction
* test for stopping autolocks for full mempool
* Inject "simple autolockable" txes into txlockrequest logic
* Drop nBudgetProposalEstablishingTime
* Refactor: replace `== COutPoint()` with `.IsNull()`
* Refactor: add `operator bool()` to CMasternodePing
* Refactor: actually use `operator bool()` for CPendingDsaRequest
* Refactor: fixing code style in TrafficGraphData
* Fix some comments and whitespaces
* Drop CGovernanceVote::GetTypeHash()
* Drop legacy X11 code
No longer used... if it ever was used at all.
* Move `<boost/foreach.hpp>` out of coins.h
* Simplify CMasternodeBlockPayees::GetRequiredPaymentsString()
Also less of boost::lexical_cast
* Drop CTxDSIn::nSentTimes
* Fix few warnings
* fix warning (timer)
* fix nit
* Use Dash block for DeserializeAndCheckBlockTest
Replaced Bitcoin block with the largest Dash block I could find on mainnet.
* Store hashDevnetGenesisBlock in Consensus::Params
Remove the need for chainparams to be available when the devnetGenesis hash
is needed. Fixes a crash in CheckBlockHeader() when called from benchmarking
code, which does not initialize the Params() function.

* IBD check uses minimumchain work instead of checkpoints.
This introduces a 'minimum chain work' chainparam which is intended
to be the known amount of work in the chain for the network at the
time of software release. If you don't have this much work, you're
not yet caught up.
This is used instead of the count of blocks test from checkpoints.
This criteria is trivial to keep updated as there is no element of
subjectivity, trust, or position dependence to it. It is also a more
reliable metric of sync status than a block count.
* Remove GetTotalBlocksEstimate and checkpoint tests that test nothing.
GetTotalBlocksEstimate is no longer used and it was the only thing
the checkpoint tests were testing.
Since checkpoints are on their way out it makes more sense to remove
the test file than to cook up a new pointless test.
# Conflicts:
# src/Makefile.test.include
# src/test/Checkpoints_tests.cpp
* IsInitialBlockDownload no longer uses header-only timestamps.
This avoids a corner case (mostly visible on testnet) where bogus
headers can keep nodes in IsInitialBlockDownload.
* Delay parallel block download until chain has sufficient work
nMinimumChainWork is an anti-DoS threshold; wait until we have a proposed
tip with more work than that before downloading blocks towards that tip.
* Add timeout for headers sync
At startup, we choose one peer to serve us the headers chain, until
our best header is close to caught up. Disconnect this peer if more
than 15 minutes + 1ms/expected_header passes and our best header
is still more than 1 day away from current time.
* Introduce assumevalid setting to skip presumed valid scripts.
This disentangles the script validation skipping from checkpoints.
A new option is introduced "assumevalid" which specifies a block whos
ancestors we assume all have valid scriptsigs and so we do not check
them when they are also burried under the best header by two weeks
worth of work.
Unlike checkpoints this has no influence on consensus unless you set
it to a block with an invalid history. Because of this it can be
easily be updated without risk of influencing the network consensus.
This results in a massive IBD speedup.
This approach was independently recommended by Peter Todd and Luke-Jr
since POW based signature skipping (see PR#9180) does not have the
verifiable properties of a specific hash and may create bad incentives.
The downside is that, like checkpoints, the defaults bitrot and older
releases will sync slower. On the plus side users can provide their
own value here, and if they set it to something crazy all that will
happen is more time will be spend validating signatures.
Checkblocks and checklevel are also moved to the hidden debug options:
Especially now that checkblocks has a low default there is little need
to change these settings, and users frequently misunderstand them as
influencing security or IBD speed. By hiding them we offset the
space added by this new option.

068c178 Added DBG macro in util.h to facilitate debugging
- This macro allows debugging statements (typically printf's or cout's) to
be activated or deactivated with a single comment. Uncomment the line:
//#define ENABLE_DASH_DEBUG
in util.h to enable debugging statements.
- When commented any code wrapped with the DBG() macro will simply be removed
by the preprocessor. When not commented all such wrapped statements will
be present.
- For maximum effectiveness it is best that util.h be the first effective include
in all source files. It is also possible to enable the macro for a single file
by temporarily adding #define ENABLE_DASH_DEBUG to the top of the file.
- Code committed to non-development branches should always have the define
commented.

dc933fe Removed unused CSuperblockManager::IsBlockValid function
decec88 Moved calls to SuperblockManager::IsValidSuperblockHeight into IsSuperblockTriggered.
- Since calls to the later function are always protected by the former there's
no reason to keep these separate and this simplifies the code in
masternode-payments.cpp.

get rid of most `if(Params().NetworkIDString() == CBaseChainParams::MAIN)` and alike to unify formulas.
Further improvements will require testnet restart (see TODO notes in changed code) so I'm keeping few things as they are till then.
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.
Revert "Revert "Add rules--presently disabled--for using GetMedianTimePast as endpoint for lock-time calculations""
This reverts commit 40cd32e835.
After careful analysis it was determined that the change was, in fact, safe and several people were suffering
momentary confusion about locktime semantics.
This reverts commit 9d55050773.
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.
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.
Add a field `strDebugMessage` which can be passed to DoS or Invalid,
and queried using GetDebugMessage() to add extra troubleshooting
information to the validation state.
