* 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
Not present anymore after rebase on develop
* 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.
* 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.

b6b6d6c Added nSuperblockStartBlock, adjusted testnet/regtest params
15a3c64 More for governance block checks, p1 (non-compilable):
- add GetPaymentsLimit() and GetPaymentsTotalAmount()
- IsValidBlockHeight() should check nSuperblockStartBlock
- CSuperblock::IsValid should check payment limit and miner payout
- no cs_main
- slightly refactored related things
e8f9e5d More for governance checks, p2 (compilable):
- IsBlockValueValid(), IsBlockPayeeValid() and FillBlockPayee() rewritten, no cs_main for them
- CreateNewBlock adjusted, need more work on CBlockTemplate (see TODO)
- moved (and simplified) IsBlockPayeeValid() call from CheckBlock() to ConnectBlock()
51434cf Add ability to calculate only superblock part of subsidy in GetBlockSubsidy()
aa74200 Fix GetPaymentsLimit()
f7b6234 braces and comment
ade8f64 more checks for IsValidBlockHeight()
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.
d125d9b V0.12.1.x -- merging trigger/generic object/superblock changes for testnet phase II
- This commit contains the core governance system changes for 0.12.1. Any unrelated
changes have either been removed or moved to separate commits.
120724c File mode fixes
- Changed mode 0755->0644 on several source files.
c7f9e11 Updated todo reminders
- Added reminder to revert temporary reduction of number of votes
required to trigger superblock to 1 for testing
92adc98 Made CSuperblockManager::IsValidSuperblockHeight an inline function
- This is for efficiency since this function is called often and is
only 1 line of code.
c050ed7 Added comment explaining rationale for no LOCK(cs) in CSuperblock::IsValid
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.
8672885 Reestablished expected value check for non-superblocks in IsBlockValueValid
b01cbe0 Changes to IsBlockValueValid to fix rpc test failure
a937c76 Changed include order to allow per file activation of the DBG macro
d116aa5 Fixed IsValidSuperblockHeight logic
- Note this has an effect on testing because we can now only create
1 superblock per day. Devs may need to temporarily change testnet params
for easier testing.
2d0c2de Convert superblock payments to CAmount
- We assume that payment values in JSON are in units of DASH
for consistency with other RPC functions, such as
createrawtransaction.
376b833 Revert temporary testing value for nAbsVoteReq
- Also ensure that number of votes required is never smaller than 1
8c89f4b Cleaned up CSuperblock error handling
- Exceptions are now thrown consistently rather than using a mix of
exceptions and return code checking. Exceptions are now caught only
in AddNewTrigger when the CSuperblock constructor is called. Unnecessary object
status members have been removed.
d7c8a6b Removed utilstrencodings header
- This appears to help with travis tests, for unknown reasons.
c4dfc7a Fixed some minor code review issues

- move ProcessSpork, GetSporkValue, IsSporkActive, ExecuteSpork and mapSporksActive to CSporkManager
- move Sign, CheckSignature, Relay to CSporkMessage
- move ReprocessBlocks out of sporks to main.cpp / rename DisconnectBlocksAndReprocess to DisconnectBlocks
- rename SporkKey to SporkPubKey
- bugfix: only set strMasterPrivKey if spork signature produced by that key was verified successfully
- few log format changes, cleaned up includes
- use "" account address instead
- remove `collateralPubKey` and `SetCollateralAddress()` from darksend and create `dummyScriptPubkey` and `InitDummyScriptPubkey()` in masternodeman instead
- initialize `dummyScriptPubkey` before loading cache otherwise MNs could be removed because of the invalid tx
