Introduce a CChainParameters singleton class and regtest mode. The new class is accessed via the Params() method and holds most things that vary between main, test and regtest networks. The regtest mode has two purposes, one is to run the bitcoind/bitcoinj comparison tool which compares two separate implementations of the Bitcoin protocol looking for divergence. The other is that when run, you get a local node which can mine a single block instantly, which is highly convenient for testing apps during development as there's no need to wait 10 minutes for a block on the testnet.

#include "chainparams.h"
Switch blocks to a constant-space Merkle root/branch algorithm. 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.

Cleanup code using forward declarations. Use misc methods of avoiding unnecesary header includes. Replace int typedefs with int##_t from stdint.h. Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h. Normalize QT_VERSION ifs where possible. Resolve some indirect dependencies as direct ones. Remove extern declarations from .cpp files.

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 Not present anymore after rebase on develop

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.

Prepare testnet for upgrade
2015-08-02 16:28:38 +02:00
Introduce a CChainParameters singleton class and regtest mode. The new class is accessed via the Params() method and holds most things that vary between main, test and regtest networks. The regtest mode has two purposes, one is to run the bitcoind/bitcoinj comparison tool which compares two separate implementations of the Bitcoin protocol looking for divergence. The other is that when run, you get a local node which can mine a single block instantly, which is highly convenient for testing apps during development as there's no need to wait 10 minutes for a block on the testnet.

A pack of small fixes (#1992) * Make sure gobject collateral was mined `CGovernanceObject::IsCollateralValid()` would still fail for non-mined collateral later trying to check confirmations * Fix powLimit for mainnet/testnet That's a legacy thing, slightly rising it to match the actual bit-shifted value has no effect because real values are already lower. Also clarify values for all networks in comments. * Check for script addresses in CSuperblock::ParsePaymentSchedule() Sentinel should already be downvoting such triggers if they would exist, no need to store/relay them. * Do not process already known valid vote twice in CGovernanceObject::ProcessVote() This should be handled by `CGovernanceManager::ProcessVote()` but imo it's better to have this at the `CGovernanceObject::ProcessVote()` level as well. * Make sure CGovernanceObjectVoteFile::AddVote() never adds/updates already known votes The way `CGovernanceObjectVoteFile::AddVote()` is used (i.e. wrapped in `CGovernanceObjectVoteFile::HasVote()` condition) it's already the case. Hoever nothing would guarantee consistency if it would be used elsewhere without such wrapper, so it's better to have similar check inside. * Do not even try mnb recovery when -connect is set `CConnman::ThreadOpenMasternodeConnections()` thread won't even start when `-connect` is set, so no need to ask for recovery, there is nothing that is going to be able to process such request. * No need for SIGHASH_ANYONECANPAY in PS collateral signature Collateral is just a normal tx created and signed by each participant individually, there is no need for special sig types. * Release semMasternodeOutbound in CConnman::Interrupt() Re-align Dash code with Bitcoin.

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

Add block pruning functionality This adds a -prune=N option to bitcoind, which if set to N>0 will enable block file pruning. When pruning is enabled, block and undo files will be deleted to try to keep total space used by those files to below the prune target (N, in MB) specified by the user, subject to some constraints: - The last 288 blocks on the main chain are always kept (MIN_BLOCKS_TO_KEEP), - N must be at least 550MB (chosen as a value for the target that could reasonably be met, with some assumptions about block sizes, orphan rates, etc; see comment in main.h), - No blocks are pruned until chainActive is at least 100,000 blocks long (on mainnet; defined separately for mainnet, testnet, and regtest in chainparams as nPruneAfterHeight). This unsets NODE_NETWORK if pruning is enabled. Also included is an RPC test for pruning (pruning.py). Thanks to @rdponticelli for earlier work on this feature; this is based in part off that work.

Introduce a CChainParameters singleton class and regtest mode. The new class is accessed via the Params() method and holds most things that vary between main, test and regtest networks. The regtest mode has two purposes, one is to run the bitcoind/bitcoinj comparison tool which compares two separate implementations of the Bitcoin protocol looking for divergence. The other is that when run, you get a local node which can mine a single block instantly, which is highly convenient for testing apps during development as there's no need to wait 10 minutes for a block on the testnet.

It only applies to the current chain which activated DIP3 at height 264000 and block 00000048e6e71d4bd90e7c456dcb94683ae832fcad13e1760d8283f7e89f332f.

The also changes the error types that are possible from 3 to 2 now.

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 Not present anymore after rebase on develop

Use spork addresses instead of raw keys and allow changing them on startup (#1969) * Support passing CKeyID to CMessageSigner/CHashSigner * Use Dash addresses instead of raw public keys for sporks The spork addresses are identical to the previously used public keys. Also use CKeyID/CKey directly inside CSporkManager instead of parsing the addresses/keys over and over. The default spork key (from chainparams) is initialized with InitDefaultSporkAddress(). SetPrivKey parses the private key now and stores it in sporkPrivKey instead of parsing it in CSporkMessage::Sign(). * Allow setting of spork address via command line * Remove unused strMasternodePaymentsPubKey chainparam Traces from the past... * Review fixes 1. Remove the need for InitDefaultSporkAddress 2. Remove bogus checks for hex private keys 3. Alphabetical order for new include 4.

Prepare DIP3 for testnet and reuse DIP3 deployment for autoix deployment (#2389) * 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.

Introduce a CChainParameters singleton class and regtest mode. The new class is accessed via the Params() method and holds most things that vary between main, test and regtest networks. The regtest mode has two purposes, one is to run the bitcoind/bitcoinj comparison tool which compares two separate implementations of the Bitcoin protocol looking for divergence. The other is that when run, you get a local node which can mine a single block instantly, which is highly convenient for testing apps during development as there's no need to wait 10 minutes for a block on the testnet.

Also clarify values for all networks in comments. * Check for script addresses in CSuperblock::ParsePaymentSchedule() Sentinel should already be downvoting such triggers if they would exist, no need to store/relay them. * Do not process already known valid vote twice in CGovernanceObject::ProcessVote() This should be handled by `CGovernanceManager::ProcessVote()` but imo it's better to have this at the `CGovernanceObject::ProcessVote()` level as well. * Make sure CGovernanceObjectVoteFile::AddVote() never adds/updates already known votes The way `CGovernanceObjectVoteFile::AddVote()` is used (i.e. wrapped in `CGovernanceObjectVoteFile::HasVote()` condition) it's already the case. Hoever nothing would guarantee consistency if it would be used elsewhere without such wrapper, so it's better to have similar check inside. * Do not even try mnb recovery when -connect is set `CConnman::ThreadOpenMasternodeConnections()` thread won't even start when `-connect` is set, so no need to ask for recovery, there is nothing that is going to be able to process such request. * No need for SIGHASH_ANYONECANPAY in PS collateral signature Collateral is just a normal tx created and signed by each participant individually, there is no need for special sig types. * Release semMasternodeOutbound in CConnman::Interrupt() Re-align Dash code with Bitcoin.

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

Add block pruning functionality This adds a -prune=N option to bitcoind, which if set to N>0 will enable block file pruning. When pruning is enabled, block and undo files will be deleted to try to keep total space used by those files to below the prune target (N, in MB) specified by the user, subject to some constraints: - The last 288 blocks on the main chain are always kept (MIN_BLOCKS_TO_KEEP), - N must be at least 550MB (chosen as a value for the target that could reasonably be met, with some assumptions about block sizes, orphan rates, etc; see comment in main.h), - No blocks are pruned until chainActive is at least 100,000 blocks long (on mainnet; defined separately for mainnet, testnet, and regtest in chainparams as nPruneAfterHeight). This unsets NODE_NETWORK if pruning is enabled. Also included is an RPC test for pruning (pruning.py). Thanks to @rdponticelli for earlier work on this feature; this is based in part off that work.

Introduce a CChainParameters singleton class and regtest mode. The new class is accessed via the Params() method and holds most things that vary between main, test and regtest networks. The regtest mode has two purposes, one is to run the bitcoind/bitcoinj comparison tool which compares two separate implementations of the Bitcoin protocol looking for divergence. The other is that when run, you get a local node which can mine a single block instantly, which is highly convenient for testing apps during development as there's no need to wait 10 minutes for a block on the testnet.

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

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 Not present anymore after rebase on develop

Also use CKeyID/CKey directly inside CSporkManager instead of parsing the addresses/keys over and over. The default spork key (from chainparams) is initialized with InitDefaultSporkAddress(). SetPrivKey parses the private key now and stores it in sporkPrivKey instead of parsing it in CSporkMessage::Sign(). * Allow setting of spork address via command line * Remove unused strMasternodePaymentsPubKey chainparam Traces from the past... * Review fixes 1.

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.

Introduce a CChainParameters singleton class and regtest mode. The new class is accessed via the Params() method and holds most things that vary between main, test and regtest networks. The regtest mode has two purposes, one is to run the bitcoind/bitcoinj comparison tool which compares two separate implementations of the Bitcoin protocol looking for divergence. The other is that when run, you get a local node which can mine a single block instantly, which is highly convenient for testing apps during development as there's no need to wait 10 minutes for a block on the testnet.

Also clarify values for all networks in comments. * Check for script addresses in CSuperblock::ParsePaymentSchedule() Sentinel should already be downvoting such triggers if they would exist, no need to store/relay them. * Do not process already known valid vote twice in CGovernanceObject::ProcessVote() This should be handled by `CGovernanceManager::ProcessVote()` but imo it's better to have this at the `CGovernanceObject::ProcessVote()` level as well. * Make sure CGovernanceObjectVoteFile::AddVote() never adds/updates already known votes The way `CGovernanceObjectVoteFile::AddVote()` is used (i.e. wrapped in `CGovernanceObjectVoteFile::HasVote()` condition) it's already the case. Hoever nothing would guarantee consistency if it would be used elsewhere without such wrapper, so it's better to have similar check inside. * Do not even try mnb recovery when -connect is set `CConnman::ThreadOpenMasternodeConnections()` thread won't even start when `-connect` is set, so no need to ask for recovery, there is nothing that is going to be able to process such request. * No need for SIGHASH_ANYONECANPAY in PS collateral signature Collateral is just a normal tx created and signed by each participant individually, there is no need for special sig types. * Release semMasternodeOutbound in CConnman::Interrupt() Re-align Dash code with Bitcoin.

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 Not present anymore after rebase on develop

Prepare DIP3 for testnet and reuse DIP3 deployment for autoix deployment (#2389) * 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.

class CRegTestParams : public CChainParams {
Introduce a CChainParameters singleton class and regtest mode. The new class is accessed via the Params() method and holds most things that vary between main, test and regtest networks. The regtest mode has two purposes, one is to run the bitcoind/bitcoinj comparison tool which compares two separate implementations of the Bitcoin protocol looking for divergence. The other is that when run, you get a local node which can mine a single block instantly, which is highly convenient for testing apps during development as there's no need to wait 10 minutes for a block on the testnet.

Also clarify values for all networks in comments. * Check for script addresses in CSuperblock::ParsePaymentSchedule() Sentinel should already be downvoting such triggers if they would exist, no need to store/relay them. * Do not process already known valid vote twice in CGovernanceObject::ProcessVote() This should be handled by `CGovernanceManager::ProcessVote()` but imo it's better to have this at the `CGovernanceObject::ProcessVote()` level as well. * Make sure CGovernanceObjectVoteFile::AddVote() never adds/updates already known votes The way `CGovernanceObjectVoteFile::AddVote()` is used (i.e. wrapped in `CGovernanceObjectVoteFile::HasVote()` condition) it's already the case. Hoever nothing would guarantee consistency if it would be used elsewhere without such wrapper, so it's better to have similar check inside. * Do not even try mnb recovery when -connect is set `CConnman::ThreadOpenMasternodeConnections()` thread won't even start when `-connect` is set, so no need to ask for recovery, there is nothing that is going to be able to process such request. * No need for SIGHASH_ANYONECANPAY in PS collateral signature Collateral is just a normal tx created and signed by each participant individually, there is no need for special sig types. * Release semMasternodeOutbound in CConnman::Interrupt() Re-align Dash code with Bitcoin.

Clean up chainparams some more. Clean up the code in chainparams a bit more after the recent refactorings. In particular, make sure the structure of the "RegTest" params matches the structure of the other classes. This makes the code clearer to read. Also remove redundant values of the genesis block in always-specified optional arguments and mark variable/argument as "const".

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

When pruning is enabled, block and undo files will be deleted to try to keep total space used by those files to below the prune target (N, in MB) specified by the user, subject to some constraints: - The last 288 blocks on the main chain are always kept (MIN_BLOCKS_TO_KEEP), - N must be at least 550MB (chosen as a value for the target that could reasonably be met, with some assumptions about block sizes, orphan rates, etc; see comment in main.h), - No blocks are pruned until chainActive is at least 100,000 blocks long (on mainnet; defined separately for mainnet, testnet, and regtest in chainparams as nPruneAfterHeight). This unsets NODE_NETWORK if pruning is enabled. Also included is an RPC test for pruning (pruning.py). Thanks to @rdponticelli for earlier work on this feature; this is based in part off that work.

Introduce a CChainParameters singleton class and regtest mode. The new class is accessed via the Params() method and holds most things that vary between main, test and regtest networks. The regtest mode has two purposes, one is to run the bitcoind/bitcoinj comparison tool which compares two separate implementations of the Bitcoin protocol looking for divergence. The other is that when run, you get a local node which can mine a single block instantly, which is highly convenient for testing apps during development as there's no need to wait 10 minutes for a block on the testnet.

Clean up chainparams some more. Clean up the code in chainparams a bit more after the recent refactorings. In particular, make sure the structure of the "RegTest" params matches the structure of the other classes. This makes the code clearer to read. Also remove redundant values of the genesis block in always-specified optional arguments and mark variable/argument as "const".

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 Not present anymore after rebase on develop

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.

Introduce a CChainParameters singleton class and regtest mode. The new class is accessed via the Params() method and holds most things that vary between main, test and regtest networks. The regtest mode has two purposes, one is to run the bitcoind/bitcoinj comparison tool which compares two separate implementations of the Bitcoin protocol looking for divergence. The other is that when run, you get a local node which can mine a single block instantly, which is highly convenient for testing apps during development as there's no need to wait 10 minutes for a block on the testnet.

Remove unnecessary dependencies for bitcoin-cli This commit removes all the unnecessary dependencies (key, core, netbase, sync, ...) from bitcoin-cli. To do this it shards the chain parameters into BaseParams, which contains just the RPC port and data directory (as used by utils and bitcoin-cli) and Params, with the rest.

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 Not present anymore after rebase on develop
