Implement and enforce DIP6 commitments (#2477)
* Add LLMQ parameters to consensus params

* Add DIP6 quorum commitment special TX

* Implement CQuorumBlockProcessor which validates and handles commitments

* Add quorum commitments to new blocks

* Propagate QFCOMMITMENT messages to all nodes

* Allow special transactions in blocks which have no inputs/outputs

But only for TRANSACTION_QUORUM_COMMITMENT for now.

* Add quorum commitments to self-crafted blocks in DIP3 tests

* Add simple fork logic for current testnet

This should avoid a fork on the current testnet. It only applies to the
current chain which activated DIP3 at height 264000 and block
00000048e6e71d4bd90e7c456dcb94683ae832fcad13e1760d8283f7e89f332f.

When we revert the chain to retest the DIP3 deployment, this fork logic
can be removed again.

* Use quorumVvecHash instead of quorumHash to make null commitments unique

Implementation of https://github.com/dashpay/dips/pull/31

* Re-add quorum commitments after pruning mempool selected blocks

* Refactor CQuorumBlockProcessor::ProcessBlock to have less nested if/else statements

Also add BEGIN/END markers for temporary code.

* Add comments/documentation to LLMQParams

* Move code which determines if a commitment is required into IsCommitmentRequired

This should make the code easier to read and also removes some duplication.

The also changes the error types that are possible from 3 to 2 now. Instead
of having "bad-qc-already-mined" and "bad-qc-not-mining-phase", there is
only "bad-qc-not-allowed" now.

* Use new parameter from consensus parames for the temporary fork

e66c4e184f Don't revert to INV based block announcements when the previous block is the devnet genesis block (#2388)

b5142ee2ce Implement RemoveAskFor to indicate that we're not interested in an item anymore (#2384)
* Implement RemoveAskFor to indicate that we're not interested in an item anymore

When an INV item is received from the first node, the item is requested
immediately. If the same item is received from another node, an entry is
added to mapAskFor which marks the item for re-requesting in case the first
node did not respond. When the item is received from the first node,
the item was previously never removed from mapAskFor. Only the later getdata
loop in SendMessages would then gradually remove items from the map. This
is quite delayed however as the entries in mapAskFor have a timeout value.

RemoveAskFor allows to remove all entries from mapAskFor and setAskFor
when we are not interested in the item anymore (e.g. because we received
it already).

* Call RemoveAskFor whenever we receive a message

* Only pass hash instead of CInv object to RemoveAskFor

c9d2745188 Use BLS keys for the DIP3 operator key (#2352)
* Use BLS keys for operator keys

* Add "bls generate" RPC to generate BLS keys

* Use unique_ptr to store blsKeyOperator and blsPubKeyOperator

Needed because the Chia BLS library crashes when keys are created before
the library is initialized, even if keys are not used. This is the case here
as we have static instances here.

* Remove unnecessary CheckSignature calls

This seems to be some garbage I left in by mistake.

* Fixed review comments

* Fix rpc help for operator keys

All keys that are used as examples are random. None of the secret keys
belongs to any of the public keys.

* Use .GetHash() instead of ::SerializeHash() for BLS pubkeys in txmempool.cpp

* Rename mapProTxBlsPubKeys to mapProTxBlsPubKeyHashes

5454bea377 Automatic InstantSend locks for "simple" transactions (#2140)
* 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

25545fc1e7 Split keyIDMasternode into keyIDOwner/keyIDOperator/keyIDVoting (#2248)
* Split keyIDMasternode into keyIDOwner/keyIDOperator/keyIDVoting

keyIDOwner is the key used for things which should stay in control of the
collateral owner, like proposal voting.

keyIDOperator is the key used for operational things, like signing network
messages, signing trigger/watchdog objects and trigger votes.

keyIDVoting is the key used for proposal voting

Legacy masternodes will always have the same key for all 3 to keep
compatibility.

Using different keys is only allowed after spork15 activation.

* Forbid reusing collateral keys for operator/owner keys and vice versa

* Bump SERIALIZATION_VERSION_STRING in CMasternodeMan

99b2789a73 Fix DeserializeAndCheckBlockTest benchmark and store hashDevnetGenesisBlock in consensus (#1888)
* 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.

Bitcoin #7840 has split the INVs to send into block and TX and completely
ignores non-tx/non-block items in PushInventory. This is fine for Bitcoin,
as they only use it for blocks and TXs, but we also have a lot of MN related

cd9c6994c2 Implement named devnets (#1791)
* Initial devnet

* Move genesis block adding into its own method

* Introduce -allowprivatenet to lift limitation on RFC1918 addresses

Normally, RFC1918 (192.168.x.x/10.x.x.x/...) addresses are not allowed
to be relayed. Also, masternodes won't start when the address is considered
invalid.

This is needed to test local devnet or regtest based networks.

* Lift the requirement of minimum MN age for regtest/devnet

* Implement named devnets

This allows the creation of multiple independent devnets. Each one is
identified by a name which is hardened into a "devnet genesis" block,
which is automatically positioned at height 1. Validation rules will
ensure that a node from devnet=test1 never be able to accept blocks
from devnet=test2. This is done by checking the expected devnet genesis
block.

The genesis block of the devnet is the same as the one from regtest. This
starts the devnet with a very low difficulty, allowing us to fill up
needed balances for masternodes very fast.

Also, the devnet name is put into the sub-version of the VERSION message.
If a node connects to the wrong network, it will immediately be disconnected.

* Allow to select multiple addresses from the same group in devnet/regtest

The selection code normally only allows to select addresses from the same
group (e.g. 192.168.x.x) once. This results in connecting to only a single
node in devnet/regtest.

* Show the devnet name in the title bar and on the loading screen

* Add AllowMultipleAddressesFromGroup to chainparams and use it in net.cpp

* Remove unused/unneeded scripts from devnet geneses creation

1. OP_RETURN not needed in input script of devnet genesis
2. genesisOutputScript was unused

* Fix copy/paste error in -allowprivatenet description

* Improve -devnet parameter error handling

- Only allow one of -devnet, -regtest or -testnet
- Only allow -devnet=name to be specified once

* Use different datadir for each devnet

* Fix `devnet-devnet` issue

* Fix devnet splashscreen (should use testnet img)

* Avoid passing devNetName around (most of the time)

* Remove nMaxTipAge from CDevNetParams

753b1e486b Eliminate remaining uses of g_connman in Dash-specific code. (#1635)
This monstrous change eliminates all remaining uses of
g_connman global variable in Dash-specific code.

Unlike previous changes eliminating g_connman use
that were isolated to particular modules, this one covers
multiple modules simultaneously because they are so interdependent
that change in one module was quickly spreading to others.

This is mostly invariant change that was done by
* changing all functions using g_connman to use connman argument,
* changing all functions calling these functions to use connman argument,
* repeating previous step until there's nothing to change.

After multiple iterations, this process converged to final result,
producing code that is mostly equivalent to original one, but passing
CConnman instance through arguments instead of global variable.

The only exception to equivalence of resulting code is that I had to
create overload of CMasternodeMan::CheckAndRemove() method without arguments
that does nothing just for use in CFlatDB<CMasternodeMan>::Dump() and
CFlatDB<CMasternodeMan>::Load() methods.
Normal CMasternodeMan::CheckAndRemove() overload now has argument of
CConnman& type and is used everywhere else.

The normal overload has this code in the beginning:

    if(!masternodeSync.IsMasternodeListSynced()) return;

Masternode list is not synced yet when we load "mncache.dat" file,
and we save "mncache.dat" file on shutdown, so I presume that it's OK
to use overload that does nothing in both cases.

169afafd50 Fix duplicate headers download in initial sync (#1589)
* Fix duplicate headers download in initial sync

Now that initial block download is delayed until the headers sync is done,
it was noticed that the initial headers sync may happen multiple times in
parallel in the case new blocks are announced. This happens because for
every block in INV that is received, a getheaders message is immediately
sent out resulting in a full download of the headers chain starting from
the point of where the initial headers sync is currently at. This happens
once for each peer that announces the new block. This slows down the
initial headers sync and increases the chance of another block being
announced before it is finished, probably leading to the same behavior
as already described, slowing down the sync even more...and so on.

This commit delays sending of GETHEADERS to later in case the chain is too
far behind while a new block gets announced. Header chains will still be
downloaded multiple times, but the downloading will start much closer
to the tip of the chain, so the damage is not that bad anymore.

This ensures that we get all headers from all peers, even if any of them
is on another chain. This should avoid what happened in
https://github.com/bitcoin/bitcoin/pull/8054
which needed to be reverted later.

This fixes the Bitcoin issue https://github.com/bitcoin/bitcoin/issues/6755

* Introduce DelayGetHeadersTime chain param and fix tests

The delaying of GETHEADERS in combination with very old block times in
test cases resulted in the delaying being triggered when the first newly
mined block arrives. This results in a completely stalled sync.

This is fixed by avoiding delaying in when running tests.

* Disconnect peers which are not catched up

Peers which stop sending us headers too early are very likely peers which
did not catch up before and stalled for some reason. We should disconnect
these peers and chose another one to continue.

76181f5757 Do not add random inbound peers to addrman. (#1593)
We should learn about new peers via address messages.

An inbound peer connecting to us tells us nothing about
 its ability to accept incoming connections from us, so
 we shouldn't assume that we can connect to it based on
 this.

The vast majority of nodes on the network do not accept
 incoming connections, adding them will only slow down
 the process of making a successful connection in the
 future.

Nodes which have configured themselves to not announce would prefer we
 not violate their privacy by announcing them in GETADDR responses.

ccee103a0e Backport "assumed valid blocks" feature from Bitcoin 0.13 (#1582)
* 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.

* Add consensusParams to FindNextBlocksToDownload

* Adjust check in headers timeout logic to align with 144 blocks in Dash

2472999da0 Backport Bitcoin PR#9441: Net: Massive speedup. Net locks overhaul (#1586)
* net: fix typo causing the wrong receive buffer size

Surprisingly this hasn't been causing me any issues while testing, probably
because it requires lots of large blocks to be flying around.

Send/Recv corks need tests!

* net: make vRecvMsg a list so that we can use splice()

* net: make GetReceiveFloodSize public

This will be needed so that the message processor can cork incoming messages

* net: only disconnect if fDisconnect has been set

These conditions are problematic to check without locking, and we shouldn't be
relying on the refcount to disconnect.

* net: wait until the node is destroyed to delete its recv buffer

when vRecvMsg becomes a private buffer, it won't make sense to allow other
threads to mess with it anymore.

* net: set message deserialization version when it's actually time to deserialize

We'll soon no longer have access to vRecvMsg, and this is more intuitive anyway.

* net: handle message accounting in ReceiveMsgBytes

This allows locking to be pushed down to only where it's needed

Also reuse the current time rather than checking multiple times.

* net: record bytes written before notifying the message processor

* net: Add a simple function for waking the message handler

This may be used publicly in the future

* net: remove useless comments

* net: remove redundant max sendbuffer size check

This is left-over from before there was proper accounting. Hitting 2x the
sendbuffer size should not be possible.

* net: rework the way that the messagehandler sleeps

In order to sleep accurately, the message handler needs to know if _any_ node
has more processing that it should do before the entire thread sleeps.

Rather than returning a value that represents whether ProcessMessages
encountered a message that should trigger a disconnnect, interpret the return
value as whether or not that node has more work to do.

Also, use a global fProcessWake value that can be set by other threads,
which takes precedence (for one cycle) over the messagehandler's decision.

Note that the previous behavior was to only process one message per loop
(except in the case of a bad checksum or invalid header). That was changed in
PR #3180.

The only change here in that regard is that the current node now falls to the
back of the processing queue for the bad checksum/invalid header cases.

* net: add a new message queue for the message processor

This separates the storage of messages from the net and queued messages for
processing, allowing the locks to be split.

* net: add a flag to indicate when a node's process queue is full

Messages are dumped very quickly from the socket handler to the processor, so
it's the depth of the processing queue that's interesting.

The socket handler checks the process queue's size during the brief message
hand-off and pauses if necessary, and the processor possibly unpauses each time
a message is popped off of its queue.

* net: add a flag to indicate when a node's send buffer is full

Similar to the recv flag, but this one indicates whether or not the net's send
buffer is full.

The socket handler checks the send queue when a new message is added and pauses
if necessary, and possibly unpauses after each message is drained from its buffer.

* net: remove cs_vRecvMsg

vRecvMsg is now only touched by the socket handler thread.

The accounting vars (nRecvBytes/nLastRecv/mapRecvBytesPerMsgCmd) are also
only used by the socket handler thread, with the exception of queries from
rpc/gui. These accesses are not threadsafe, but they never were. This needs to
be addressed separately.

This avoids having some vars set if the version negotiation fails.

Also copy it all into CNode at the same site. nVersion and
fSuccessfullyConnected are set last, as they are the gates for the other vars.
Make them atomic for that reason.

* net: don't run callbacks on nodes that haven't completed the version handshake

Since ForEach* are can be used to send messages to  all nodes, the caller may
end up sending a message before the version handshake is complete. To limit
this, filter out these nodes. While we're at it, may as well filter out
disconnected nodes as well.

Delete unused methods rather than updating them.

* net: Disallow sending messages until the version handshake is complete

This is a change in behavior, though it's much more sane now than before.

* net: log an error rather than asserting if send version is misused

Also cleaned up the comments and moved from the header to the .cpp so that
logging headers aren't needed from net.h

* Implement conditions for ForEachNode() and ForNode() methods of CConnman.

A change making ForEachNode() and ForNode() methods ignore nodes that
have not completed initial handshake have been backported from Bitcoin.
Unfortunately, some Dash-specific code needs to iterate over all nodes.

This change introduces additional condition argument to these methods.
This argument is a functional object that should return true for nodes
that should be taken into account, not ignored.

Two functional objects are provided in CConnman namespace:
* FullyConnectedOnly returns true for nodes that have handshake completed,
* AllNodes returns true for all nodes.

Overloads for ForEachNode() and ForNode() methods without condition argument
are left for compatibility with non-Dash-specific code.
They use FullyConnectedOnly functional object for condition.
