Syscoin Core 4.4.2

Mon, 27 Mar 2023 00:00:00 +0000

Syscoin Core installation binaries can be downloaded from syscoincore.org and the source-code is available from the Syscoin Core source repository.

4.4.2 Release Notes

Syscoin Core version 4.4.2 is now available from:

https://github.com/syscoin/syscoin/releases/tag/v4.4.2

Hot Fix for the following issues:

coincontrol issues not selecting the right amounts and crashing if using the “use available balance” button
presync looping (i think was geth in invalid state, so we just disable geth connection for the sync)
sendrawtransaction (for sys burn to nevm we skip the max burn check). This should fix pali/blockbook
gobject_prepare fix which wasn’t signing before sending the transaction. Useful for people creating governance proposals
Large rollback on nevm fix, which causes general issues related to pruning PoDA when transaction is removed from mempool as a “reorg”, we shouldn’t do this because upon subsequent block validation the block will not validate.

Note: Masternode operators should upgrade their sentinel to v4.4.0

Please report bugs using the issue tracker at GitHub:

Upgrade Instructions: https://syscoin.readme.io/v4.4.2/docs/syscoin-442-upgrade-guide Basic upgrade instructions below:

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Syscoin-Qt (on Mac) or syscoind/syscoin-qt (on Linux).

If you are upgrading from a version older than 4.2.0, PLEASE READ: https://syscoin.readme.io/v4.2.0/docs/syscoin-42-upgrade-guide

Compatibility

Syscoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.15+, and Windows 7 and newer. It is not recommended to use Syscoin Core on unsupported systems.

Syscoin Core should also work on most other Unix-like systems but is not as frequently tested on them.

From Syscoin Core 4.4.0 onwards, macOS versions earlier than 10.15 are no longer supported.

Syscoin Core 4.4.1

Sat, 18 Mar 2023 00:00:00 +0000

Syscoin Core installation binaries can be downloaded from syscoincore.org and the source-code is available from the Syscoin Core source repository.

4.4.1 Release Notes

Syscoin Core version 4.4.1 is now available from:

https://github.com/syscoin/syscoin/releases/tag/v4.4.1

This is a hot fix release for users of Syscoin Core on OSX ARM M1/M2 and Windows:

Non-supported geth systems like arm OSX M1/M2 should not run geth at all and shouldn’t stop at blocks that require NEVM
Prune was being enabled on some systems by default which disabled governance which led to coinbase-pays-too-much error which we fixed
Windows installer puts binaries in a new location (daemon directory) and we correctly look for sysgeth there on startup You should just install and run, if you were previous stuck on a block you can reindex to fix.

Note: Masternode operators should upgrade their sentinel to v4.4.0

Syscoin Core Changes

Bitcoin 24.0+ Core engine is now used to power consensus and security of Syscoin Core. The changeset is here in this Pull request. Note that wallet users now by default will get descriptor wallets enabled. If you are a masternode or a service that requires legacy wallets you may still create them by setting the descriptor field to false when creating wallets.

Block Structure Change

Syscoin PoDA activates

Syscoin Core asset interface removed

Calls to interact with Syscoin assets have been removed from Syscoin Core. Assets can still be accessed using syscoinjs-lib or Pali Wallet.

V19 BLS Upgrade

Once v19 hard fork is activated protx_register, protx_register_fund, protx_register_prepare RPCs will decode BLS operator public key using new basic BLS scheme. In order to support BLS public keys encoded in legacy BLS scheme a legacy parameter was added to those RPC functions.

`qcommit`

Once the hard fork is activated, quorumPublicKey will be serialised using basic BLS scheme. To support sync of old chain,version field indicates which scheme to use for serialisation of quorumPublicKey.

Version	Version Description
1	qcommit serialised using legacy BLS scheme
2	qcommit serialised using basic BLS scheme

`MNLISTDIFF` P2P message

Starting with protocol version 70017, the following field is added to the MNLISTDIFF message between cbTx.

Field	Type	Size	Description
version	uint16_t	2	Version of the `MNLISTDIFF` reply

The version field indicates which BLS scheme is used to serialise all SML entrie’s pubKeyOperator field of mnList.

Version	Version Description
1	Serialisation of `pubKeyOperator` using legacy BLS scheme
2	Serialisation of `pubKeyOperator` using basic BLS scheme

`ProTx` txs family

proregtx and proupregtx will support a new version value:

Version	Version Description
1	Serialisation of `pubKeyOperator` using legacy BLS scheme
2	Serialisation of `pubKeyOperator` using basic BLS scheme

proupservtx and prouprevtx will support a new version value:

Version	Version Description
1	Serialisation of `sig` using legacy BLS scheme
2	Serialisation of `sig` using basic BLS scheme

BLS enforced scheme

Once the hard fork is activated all remaining messages containing BLS public keys or signatures will serialise them using the new basic BLS scheme.

List of affected messages: mnauth, govobj, govobjvote, qsigshare, qsigrec, clsig, all DKG messages (qfcommit, qcontrib, qcomplaint, qjustify, qpcommit);

New RPC

getnevmblobdata: Return NEVM blob information and status from a version hash.

Multi-Quorum Chainlocks
V3 data directory issue
QT improvements for MN list

Quorums were not propagating partial CLSIG’s leading to Multi-Quorum Chainlocks to not be established. After working with Dash core developer we fixed some bugs upstream and also updated logic in our Chainlock mechanism to resolve the issue. We must have all masternodes upgrade so we can test the Chainlock mechanism to confirm the fix.

Back in Syscoin 3, data directory was set to use “strSyscoinDataDir” as the the regkey to access custom data directory set by the user for Syscoin QT. In Syscoin 4 we reset to “strDataDir” which caused some problems for those that had custom directories set or users from Syscoin 3.

We also added right-click copy fields for the Masternode list in Syscoin QT.

Syscoin Core 4.1.3

Thu, 19 Mar 2020 00:00:00 +0000

Syscoin Core installation binaries can be downloaded from syscoincore.org and the source-code is available from the Syscoin Core source repository.

4.1.3 Release Notes

Syscoin Core version 4.1.3 is now available from:

https://github.com/syscoin/syscoin/releases/tag/v4.1.3

This release includes new features, various bug fixes and performance improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

https://github.com/syscoin/syscoin/issues

Upgrade Instructions: https://syscoin.readme.io/v4.1.3/docs/syscoin-41-upgrade-guide Basic upgrade instructions below:

How to Upgrade

If you are upgrading from a version older than 4.1.0, PLEASE READ: https://syscoin.readme.io/v4.1.2/docs/syscoin-41-upgrade-guide

Upgrading directly from a version of Syscoin Core that has reached its EOL is possible, but might take some time if the datadir needs to be migrated. Old wallet versions of Syscoin Core are generally supported.

Compatibility

Syscoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.12+, and Windows 7 and newer. It is not recommended to use Syscoin Core on unsupported systems.

A target block height of 448000 has been set for upgrade deadline. Nodes not upgraded to Syscoin Core 4.1.3 may have issue syncing up to the network past block 448000 After the block height, 2 new changes will be activated on the network

The ability to bridge all ERC-20 Standard Token to Syscoin blockchain
The asset guid generated from assetnew will be deterministic

The previous in-compatibility between 4.0.x and 4.1.x is the interim .node files (specifically scrypt.node) that may exist in the binary path or /usr/local/bin on linux that may impede the functioning of the relayer. The node version used to build the relayer was incremented and thus .node requirement was removed, however if the .node files exist, it will not run the relayer and as a result Syscoin will not get the Ethereum block headers needed for consensus validation of Syscoin Mint transactions. See: https://syscoin.readme.io/v4.1.3/docs/syscoin-41-upgrade-guide

Syscoin Core should also work on most other Unix-like systems but is not as frequently tested on them. Geth is an Ethereum client that runs inside of Syscoin. The standard 64-bit Unix distribution is packaged up when installing Syscoin. If you have a distribution that does not work with the supplied binaries, you can download the binaries from: https://geth.ethereum.org/downloads/ and place it in the src/bin/linux directory. Read more: https://github.com/Syscoin/Syscoin/blob/master/src/bin/linux/README.md.

From Syscoin Core 4.1.0 onwards, macOS versions earlier than 10.12 are no longer supported. Additionally, Syscoin Core does not yet change appearance when macOS “dark mode” is activated.

Notable changes

Syscoin Core Changes

ZDAG Fixes and Optimizations

RBF (replace-by-fee) has been added and updated to work properly with assetallocation transactions. This includes correcting the behavior of handling double spend for ZDAG transactions
Doubled the relay fee of ZDAG transaction to align with the bandwidth usage
Amended ZDAG rules for optimization
- Sender balance has to be within the PoW balance within a block. This allow us to avoid doing ordering algorithms in mempool and speed up the process
Refactored ZDAG code for optimization
Fixed #390

Asset Protocol Fixes

Enabled detereminstic asset guid so someone cannot frontrun assets unknowingly to the user. This change will kick in automatically after blockheight 448000
Fixed issue with re-org when disconnecting blocks that contain mint asset transactions remove resync on miner
Fixed inconsistent TXIDs due to uninitialized CAmount in OP_RETURN
Fixed issue that allowed assetnew to have a supply balance of 0

Masternode fixes

Fixed masternodes counting against outbound resulting in extra count

Bridge Fixes

Added support for all ERC-20. Previously we were only bridging to openzeppelin standard ERC20’s as a precautionary mechanism. This feature unlocks the bridge to all standard ERC-20 implementations. This will be enabled automatically after blockheight 448000

Auxpow Fixes

Syned up auxpow code to the Bitcoin change where generate() is replaced by generatetoaddress()

New Syscoind Argument

zmqpubrawmempooltx has been added for publishing raw transactions in address when entering mempool only
zmqpubrawmempooltxhwm has been added for setting publish raw mempool transaction outbound message high water mark

Ethereum Client Version Upgrade

The Geth client bundled has been upgraded from v1.9.9 to v1.9.12

P2P and network changes

Removal of reject network messages from Bitcoin Core (BIP61)

The command line option to enable BIP61 (-enablebip61) has been removed.

This feature has been disabled by default since Syscoin Core version 4.1.0. Nodes on the network can not generally be trusted to send valid (“reject”) messages, so this should only ever be used when connected to a trusted node. Please use the recommended alternatives if you rely on this deprecated feature:

Testing or debugging of implementations of the Bitcoin P2P network protocol should be done by inspecting the log messages that are produced by a recent version of Bitcoin Core. Bitcoin Core logs debug messages (-debug=<category>) to a stream (-printtoconsole) or to a file (-debuglogfile=<debug.log>).
Testing the validity of a block can be achieved by specific RPCs:
- submitblock
- getblocktemplate with 'mode' set to 'proposal' for blocks with potentially invalid POW
Testing the validity of a transaction can be achieved by specific RPCs:
- sendrawtransaction
- testmempoolaccept
Wallets should not use the absence of “reject” messages to indicate a transaction has propagated the network, nor should wallets use “reject” messages to set transaction fees. Wallets should rather use fee estimation to determine transaction fees and set replace-by-fee if desired. Thus, they could wait until the transaction has confirmed (taking into account the fee target they set (compare the RPC estimatesmartfee)) or listen for the transaction announcement by other network peers to check for propagation.

The removal of BIP61 REJECT message support also has the following minor RPC and logging implications:

testmempoolaccept and sendrawtransaction no longer return the P2P REJECT code when a transaction is not accepted to the mempool. They still return the verbal reject reason.
Log messages that previously reported the REJECT code when a transaction was not accepted to the mempool now no longer report the REJECT code. The reason for rejection is still reported.

Updated RPCs

testmempoolaccept and sendrawtransaction no longer return the P2P REJECT code when a transaction is not accepted to the mempool. See the Section Removal of reject network messages from Bitcoin Core (BIP61) for details on the removal of BIP61 REJECT message support.
A new descriptor type sortedmulti(...) has been added to support multisig scripts where the public keys are sorted lexicographically in the resulting script.
walletprocesspsbt and walletcreatefundedpsbt now include BIP 32 derivation paths by default for public keys if we know them. This can be disabled by setting bip32derivs to false.

Build System

OpenSSL is no longer used by Syscoin Core. The last usage of the library was removed in #17265.
glibc 2.17 or greater is now required to run the release binaries. This retains compatibility with RHEL 7, CentOS 7, Debian 8 and Ubuntu 14.04 LTS. Further details can be found in #17538.

New RPCs

New settings

RPC Whitelist system. It can give certain RPC users permissions to only some RPC calls. It can be set with two command line arguments (rpcwhitelist and rpcwhitelistdefault). (#12763)

Updated settings

Importing blocks upon startup via the bootstrap.dat file no longer occurs by default. The file must now be specified with -loadblock=<file>.

The -debug=db logging category has been renamed to -debug=walletdb, to distinguish it from coindb. -debug=db has been deprecated and will be removed in the next major release.

GUI changes

The “Start Syscoin Core on system login” option has been removed on macOS.

Wallet

The wallet now by default uses bech32 addresses when using RPC, and creates native segwit change outputs.
The way that output trust was computed has been fixed in #16766, which impacts confirmed/unconfirmed balance status and coin selection.
The RPC gettransaction, listtransactions and listsinceblock responses now also includes the height of the block that contains the wallet transaction, if any.
RPC getaddressinfo changes:
- the label field has been deprecated in favor of the labels field and will be removed in an upcoming release. It can be re-enabled in the interim by launching with -deprecatedrpc=label.
- the labels behavior of returning an array of JSON objects containing name and purpose key/value pairs has been deprecated in favor of an array of label names and will be removed in 0.21. The previous behavior can be re-enabled in the interim by launching with -deprecatedrpc=labelspurpose.

Low-level changes

Command line

Command line options prefixed with main/test/regtest network names like -main.port=8333 -test.server=1 previously were allowed but ignored. Now they trigger “Invalid parameter” errors on startup.

Tests

It is now an error to use an unqualified walletdir=path setting in the config file if running on testnet or regtest networks. The setting now needs to be qualified as chain.walletdir=path or placed in the appropriate [chain] section. (#17447)
-fallbackfee was 0 (disabled) by default for the main chain, but 0.0002 by default for the test chains. Now it is 0 by default for all chains. Testnet and regtest users will have to add fallbackfee=0.0002 to their configuration if they weren’t setting it and they want it to keep working like before. (#16524)

Syscoin Core 4.1.2.1

Wed, 08 Jan 2020 00:00:00 +0000

Syscoin Core installation binaries can be downloaded from syscoincore.org and the source-code is available from the Syscoin Core source repository.

4.1.2 Release Notes

Syscoin Core version 4.1.2 is now available from:

https://github.com/syscoin/syscoin/releases/tag/v4.1.2

This release includes new features, various bug fixes and performance improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

https://github.com/syscoin/syscoin/issues

Upgrade Instructions: https://syscoin.readme.io/v4.1.2/docs/syscoin-41-upgrade-guide Basic upgrade instructions below:

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), uninstall it, on linux run make uninstall and on windows/osx uninstall through the installer/package manager. Then run the installer (on Windows) or just copy over /Applications/Syscoin-Qt (on Mac) or syscoind/syscoin-qt (on Linux). IMPORTANT: YOU SHOULD UNINSTALL PREVIOUS VERSION If you are upgrading from a version older than 4.1.0, PLEASE READ: https://syscoin.readme.io/v4.1.2/docs/syscoin-41-upgrade-guide

Compatibility

Syscoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not recommended to use Syscoin Core on unsupported systems.

The only in-compatibility between 4.0.x and 4.1.x is the interim .node files (specifically scrypt.node) that may exist in the binary path or /usr/local/bin on linux that may impede the functioning of the relayer. The node version used to build the relayer was incremented and thus .node requirement was removed, however if the .node files exist, it will not run the relayer and as a result Syscoin will not get the Ethereum block headers needed for consensus validation of Syscoin Mint transactions. See: https://syscoin.readme.io/v4.1.2/docs/syscoin-41-upgrade-guide

Syscoin Core should also work on most other Unix-like systems but is not as frequently tested on them. Geth is an Ethereum client that runs inside of Syscoin. The standard 64-bit Unix distribution is packaged up when installing Syscoin. If you have a distribution that does not work with the supplied binaries, you can download from: https://geth.ethereum.org/downloads/ and place it in the src/bin/linux directory. Read more: https://github.com/Syscoin/Syscoin/blob/master/src/bin/linux/README.md.

From 4.1.x onwards, macOS <10.10 is no longer supported. 4.0.x is built using Qt 5.9.x, which doesn’t support versions of macOS older than 10.10. Additionally, Syscoin Core does not yet change appearance when macOS “dark mode” is activated.

Notable changes

This release fixes mn broadcast scoping issue https://github.com/syscoin/syscoin/issues/385

Deprecated or removed RPCs

The getaddressinfo RPC labels field now returns an array of label name strings. Previously, it returned an array of JSON objects containing name and purpose key/value pairs, which is now deprecated and will be removed in future release of syscoind. To re-enable the previous behavior, launch syscoind with -deprecatedrpc=labelspurpose.

How to Upgrade

Compatibility

Syscoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not recommended to use Syscoin Core on unsupported systems.

Syscoin Core should also work on most other Unix-like systems but is not as frequently tested on them.

From 4.1.0 onwards, macOS <10.10 is no longer supported. 0.17.0 is built using Qt 5.9.x, which doesn’t support versions of macOS older than 10.10. Additionally, Syscoin Core does not yet change appearance when macOS “dark mode” is activated.

Notable changes

New user documentation

Reduce memory suggests configuration tweaks for running Syscoin Core on systems with limited memory. (#16339)

New RPCs

getbalances returns an object with all balances (mine, untrusted_pending and immature). Please refer to the RPC help of getbalances for details. The new RPC is intended to replace getbalance, getunconfirmedbalance, and the balance fields in getwalletinfo. These old calls and fields may be removed in a future version. (#15930, #16239)
setwalletflag sets and unsets wallet flags that enable or disable features specific to that existing wallet, such as the new avoid_reuse feature documented elsewhere in these release notes. (#13756)
getblockfilter gets the BIP158 filter for the specified block. This RPC is only enabled if block filters have been created using the -blockfilterindex configuration option. (#14121)

New settings

-blockfilterindex enables the creation of BIP158 block filters for the entire blockchain. Filters will be created in the background and currently use about 4 GiB of space. Note: this version of Syscoin Core does not serve block filters over the P2P network, although the local user may obtain block filters using the getblockfilter RPC. (#14121)

Updated settings

whitebind and whitelist now accept a list of permissions to provide peers connecting using the indicated interfaces or IP addresses. If no permissions are specified with an address or CIDR network, the implicit default permissions are the same as previous releases. See the syscoind -help output for these two options for details about the available permissions. (#16248)
Users setting custom dbcache values can increase their setting slightly without using any more real memory. Recent changes reduced the memory use by about 9% and made chainstate accounting more accurate (it was underestimating the use of memory before). For example, if you set a value of “450” before, you may now set a value of “500” to use about the same real amount of memory. (#16957)

Updated RPCs

Note: some low-level RPC changes mainly useful for testing are described in the Low-level Changes section below.

sendmany no longer has a minconf argument. This argument was not well-specified and would lead to RPC errors even when the wallet’s coin selection succeeded. Users who want to influence coin selection can use the existing -spendzeroconfchange, -limitancestorcount, -limitdescendantcount and -walletrejectlongchains configuration arguments. (#15596)
getbalance and sendtoaddress, plus the new RPCs getbalances and createwallet, now accept an “avoid_reuse” parameter that controls whether already used addresses should be included in the operation. Additionally, sendtoaddress will avoid partial spends when avoid_reuse is enabled even if this feature is not already enabled via the -avoidpartialspends command line flag because not doing so would risk using up the “wrong” UTXO for an address reuse case. (#13756)
RPCs which have an include_watchonly argument or includeWatching option now default to true for watch-only wallets. Affected RPCs are: getbalance, listreceivedbyaddress, listreceivedbylabel, listtransactions, listsinceblock, gettransaction, walletcreatefundedpsbt, and fundrawtransaction. (#16383)
listunspent now returns a “reused” bool for each output if the wallet flag “avoid_reuse” is enabled. (#13756)
getblockstats now uses BlockUndo data instead of the transaction index, making it much faster, no longer dependent on the -txindex configuration option, and functional for all non-pruned blocks. (#14802)
utxoupdatepsbt now accepts a descriptors parameter that will fill out input and output scripts and keys when known. P2SH-witness inputs will be filled in from the UTXO set when a descriptor is provided that shows they’re spending segwit outputs. See the RPC help text for full details. (#15427)
sendrawtransaction and testmempoolaccept no longer accept a allowhighfees parameter to fail mempool acceptance if the transaction fee exceeds the value of the configuration option -maxtxfee. Now there is a hardcoded default maximum feerate that can be changed when calling either RPC using a maxfeerate parameter. (#15620)
getmempoolancestors, getmempooldescendants, getmempoolentry, and getrawmempool no longer return a size field unless the configuration option -deprecatedrpc=size is used. Instead a new vsize field is returned with the transaction’s virtual size (consistent with other RPCs such as getrawtransaction). (#15637)
getwalletinfo now includes a scanning field that is either false (no scanning) or an object with information about the duration and progress of the wallet’s scanning historical blocks for transactions affecting its balances. (#15730)
gettransaction now accepts a third (boolean) argument verbose. If set to true, a new decoded field will be added to the response containing the decoded transaction. This field is equivalent to RPC decoderawtransaction, or RPC getrawtransaction when verbose is passed. (#16185, #16866, #16873)
createwallet accepts a new passphrase parameter. If set, this will create the new wallet encrypted with the given passphrase. If unset (the default) or set to an empty string, no encryption will be used. (#16394)
getchaintxstats RPC now returns the additional key of window_final_block_height. (#16695)
getmempoolentry now provides a weight field containing the transaction weight as defined in BIP141. (#16647)
The getnetworkinfo and getpeerinfo commands now contain a new field with decoded network service flags. (#16786)
getdescriptorinfo now returns an additional checksum field containing the checksum for the unmodified descriptor provided by the user (that is, before the descriptor is normalized for the descriptor field). (#15986)
joinpsbts now shuffles the order of the inputs and outputs of the resulting joined PSBT. Previously, inputs and outputs were added in the order PSBTs were provided. This made it easy to correlate inputs to outputs, representing a privacy leak. (#16512)
walletcreatefundedpsbt now signals BIP125 Replace-by-Fee if the -walletrbf configuration option is set to true. (#15911)

GUI changes

The GUI wallet now provides bech32 addresses by default. The user may change the address type during invoice generation using a GUI toggle, or the default address type may be changed with the -addresstype configuration option. (#15711, #16497)
In 0.18.0, a ./configure flag was introduced to allow disabling BIP70 support in the GUI (support was enabled by default). In 4.1.0, this flag is now disabled by default. If you want to compile Syscoin Core with BIP70 support in the GUI, you can pass --enable-bip70 to ./configure. (#15584)

Deprecated or removed configuration options

-mempoolreplacement is removed, although default node behavior remains the same. This option previously allowed the user to prevent the node from accepting or relaying BIP125 transaction replacements. This is different from the remaining configuration option -walletrbf. (#16171)

Deprecated or removed RPCs

bumpfee no longer accepts a totalFee option unless the configuration parameter deprecatedrpc=totalFee is specified. This parameter will be fully removed in a subsequent release. (#15996)
bumpfee has a new fee_rate option as a replacement for the deprecated totalFee. (#16727)
generate is now removed after being deprecated in Syscoin Core 0.18. Use the generatetoaddress RPC instead. (#15492)

P2P changes

BIP 61 reject messages were deprecated in v0.18. They are now disabled by default, but can be enabled by setting the -enablebip61 command line option. BIP 61 reject messages will be removed entirely in a future version of Syscoin Core. (#14054)
To eliminate well-known denial-of-service vectors in Syscoin Core, especially for nodes with spinning disks, the default value for the -peerbloomfilters configuration option has been changed to false. This prevents Syscoin Core from sending the BIP111 NODE_BLOOM service flag, accepting BIP37 bloom filters, or serving merkle blocks or transactions matching a bloom filter. Users who still want to provide bloom filter support may either set the configuration option to true to re-enable both BIP111 and BIP37 support or enable just BIP37 support for specific peers using the updated -whitelist and -whitebind configuration options described elsewhere in these release notes. For the near future, lightweight clients using public BIP111/BIP37 nodes should still be able to connect to older versions of Syscoin Core and nodes that have manually enabled BIP37 support, but developers of such software should consider migrating to either using specific BIP37 nodes or an alternative transaction filtering system. (#16152)
By default, Syscoin Core will now make two additional outbound connections that are exclusively used for block-relay. No transactions or addr messages will be processed on these connections. These connections are designed to add little additional memory or bandwidth resource requirements but should make some partitioning attacks more difficult to carry out. (#15759)

Miscellaneous CLI Changes

The testnet field in syscoin-cli -getinfo has been renamed to chain and now returns the current network name as defined in BIP70 (main, test, regtest). (#15566)

Low-level changes

RPC

getblockchaininfo no longer returns a bip9_softforks object. Instead, information has been moved into the softforks object and an additional type field describes how Syscoin Core determines whether that soft fork is active (e.g. BIP9 or BIP90). See the RPC help for details. (#16060)
getblocktemplate no longer returns a rules array containing CSV and segwit (the BIP9 deployments that are currently in active state). (#16060)
getrpcinfo now returns a logpath field with the path to debug.log. (#15483)

Tests

The regression test chain enabled by the -regtest command line flag now requires transactions to not violate standard policy by default. This is the same default used for mainnet and makes it easier to test mainnet behavior on regtest. Note that the testnet still allows non-standard txs by default and that the policy can be locally adjusted with the -acceptnonstdtxn command line flag for both test chains. (#15891)

Configuration

A setting specified in the default section but not also specified in a network-specific section (e.g. testnet) will now produce an error preventing startup instead of just a warning unless the network is mainnet. This prevents settings intended for mainnet from being applied to testnet or regtest. (#15629)
On platforms supporting thread_local, log lines can be prefixed with the name of the thread that caused the log. To enable this behavior, use -logthreadnames=1. (#15849)

Network

When fetching a transaction announced by multiple peers, previous versions of Syscoin Core would sequentially attempt to download the transaction from each announcing peer until the transaction is received, in the order that those peers’ announcements were received. In this release, the download logic has changed to randomize the fetch order across peers and to prefer sending download requests to outbound peers over inbound peers. This fixes an issue where inbound peers could prevent a node from getting a transaction. (#14897, #15834)
If a Tor hidden service is being used, Syscoin Core will be bound to the standard port 8333 even if a different port is configured for clearnet connections. This prevents leaking node identity through use of identical non-default port numbers. (#15651)

Mempool and transaction relay

Allows one extra single-ancestor transaction per package. Previously, if a transaction in the mempool had 25 descendants, or it and all of its descendants were over 101,000 vbytes, any newly-received transaction that was also a descendant would be ignored. Now, one extra descendant will be allowed provided it is an immediate descendant (child) and the child’s size is 10,000 vbytes or less. This makes it possible for two-party contract protocols such as Lightning Network to give each participant an output they can spend immediately for Child-Pays-For-Parent (CPFP) fee bumping without allowing one malicious participant to fill the entire package and thus prevent the other participant from spending their output. (#15681)
Transactions with outputs paying v1 to v16 witness versions (future segwit versions) are now accepted into the mempool, relayed, and mined. Attempting to spend those outputs remains forbidden by policy (“non-standard”). When this change has been widely deployed, wallets and services can accept any valid bech32 Syscoin address without concern that transactions paying future segwit versions will become stuck in an unconfirmed state. (#15846)
Legacy transactions (transactions with no segwit inputs) must now be sent using the legacy encoding format, enforcing the rule specified in BIP144. (#14039)

Wallet

When in pruned mode, a rescan that was triggered by an importwallet, importpubkey, importaddress, or importprivkey RPC will only fail when blocks have been pruned. Previously it would fail when -prune has been set. This change allows setting -prune to a high value (e.g. the disk size) without the calls to any of the import RPCs failing until the first block is pruned. (#15870)
When creating a transaction with a fee above -maxtxfee (default 0.1 BTC), the RPC commands walletcreatefundedpsbt and fundrawtransaction will now fail instead of rounding down the fee. Be aware that the feeRate argument is specified in BTC per 1,000 vbytes, not satoshi per vbyte. (#16257)
A new wallet flag avoid_reuse has been added (default off). When enabled, a wallet will distinguish between used and unused addresses, and default to not use the former in coin selection. When setting this flag on an existing wallet, rescanning the blockchain is required to correctly mark previously used destinations. Together with “avoid partial spends” (added in Syscoin Core v0.17.0), this can eliminate a serious privacy issue where a malicious user can track spends by sending small payments to a previously-paid address that would then be included with unrelated inputs in future payments. (#13756)

Build system changes

Python >=3.5 is now required by all aspects of the project. This includes the build systems, test framework and linters. The previously supported minimum (3.4), was EOL in March 2019. (#14954)
The minimum supported miniUPnPc API version is set to 10. This keeps compatibility with Ubuntu 16.04 LTS and Debian 8 libminiupnpc-dev packages. Please note, on Debian this package is still vulnerable to CVE-2017-8798 (in jessie only) and CVE-2017-1000494 (both in jessie and in stretch). (#15993)
