01coin version 0.13.0.0

Release is now available from:

https://github.com/zocteam/zeroonecoin/releases

This is a new major version release, bringing new features, various bugfixes and other improvements.

Please report bugs using the issue tracker at github:

https://github.com/zocteam/zeroonecoin/issues

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/Dash-Qt (on Mac) or dashd/dash-qt (on Linux). If you upgrade after DIP0003 activation you will have to reindex (start with -reindex-chainstate or -reindex) to make sure your wallet has all the new data synced.

Upgrading and downgrading

Downgrade to a version < 0.13.0.0

Downgrading to a version smaller than 0.13 is only supported as long as DIP2/DIP3 has not been activated. Activation will happen when enough miners signal compatibility through a BIP9 (bit 3) deployment.

Notable changes

Improve initial sync

NOTE: Introducing the new denom and a couple of other changes made it incompatible with mixing on masternodes running on pre-0.13 software. Please keep using 0.12.3 local wallet to mix your coins until there is some significant number of masternodes running on version 0.13 to make sure you have enough masternodes to choose from when the wallet picks one to mix funds on.

InstantSend

With further improvements of networking code it's now possible to handle more load, so we are changing InstantSend to be always-on for so called "simple txes" - transactions with 4 or less inputs. Such transactions will be automatically locked even if they only pay minimal fee. According to stats, this means that up to 90% of currently observed transactions will became automatically locked via InstantSend with no additional cost to end users or any additional effort from wallet developers or other service providers.

This feature is going to be activated via combination of a BIP9-like deployment (we are reusing bit 3) and new spork (SPORK_16_INSTANTSEND_AUTOLOCKS).

Historically, InstantSend transactions were shown in GUI and RPC with more confirmations than regular ones, which caused quite a bit of confusion. This will no longer be the case, instead we are going to show real blockchain confirmations only and a separate indicator to show if transaction was locked via InstantSend or not. For GUI it's color highlight and a new column, for RPC commands - instantlock field and addlocked param.

One of the issues with InstantSend adoption by SPV wallets (besides lack of Deterministic Masternode List) was inability to filter all InstantSend messages the same way transactions are filtered. This should be fixed now and SPV wallets should only get lock votes for transactions they are interested in.

Another popular request was to preserve information about InstantSend locks between wallet restarts, which is now implemented. This data is stored in a new cache file instantsend.dat. You can safely remove it, if you don't need information about recent transaction locks for some reason (NOTE: make sure it's not one of your wallets!).

We also added new ZMQ notifications for double-spend attempts which try to override transactions locked via InstantSend - zmqpubrawinstantsenddoublespend and zmqpubhashinstantsenddoublespend.

Sporks

There are a couple of new sporks introduced in this version SPORK_15_DETERMINISTIC_MNS_ENABLED (block based) and SPORK_16_INSTANTSEND_AUTOLOCKS (timestamp based). There is aslo SPORK_17_QUORUM_DKG_ENABLED (timestamp based) which is going to be used on testnet only for now.

Spork data is stored in a new cache file (sporks.dat) now.

Governance

Introduction of Deterministic Masternodes requires replacing of the old masternode private key which was used both for operating a MN and for voting on proposals with a set of separate keys, preferably fresh new ones. This means that votes casted for proposals by Masternode Owners via the old system will no longer be valid after DIP0003 activation and must be re-casted using the new voting key.

Also, you can now get notifications about governance objects or votes via new ZMQ notifications: zmqpubhashgovernancevote, zmqpubhashgovernanceobject, zmqpubrawgovernancevote and zmqpubhashgovernanceobject.

GUI changes

Masternodes tab has a new section dedicated to DIP0003 registered masternodes now. After DIP0003 activation this will be the only section shown here, the two old sections for non-deterministic masternodes will no longer be available.

There are changes in the way InstantSend transactions are displayed, see InstantSend section above.

Some other (mostly minor) issues were also fixed, see GUI part of 0.13.0.0 Change log section below for detailed list of fixes.

RPC changes

There are a few changes in existing RPC interfaces in this release:

  • gobject prepare allows to send proposal transaction as an InstantSend one and also accepts an UTXO reference to spend;
  • masternode status and masternode list show some DIP0003 related info now;
  • previousbits and coinbase_payload fields were added in getblocktemplate;
  • getblocktemplate now returns an array for masternode payments instead of a single object (miners and mining pools have to upgrade their software to support multiple masternode payees);
  • masternode and superblock payments in getblocktemplate show payee scriptPubKey in script field in addition to payee address in payee;
  • getblockchaininfo shows BIP9 deployment progress;
  • help command subCommand should give detailed help for subcommands e.g. help protx list;
  • compressed option in masternode genkey;
  • dumpwallet shows info about dumped wallet and warns user about security issues;
  • instantlock field added in output of getrawmempool, getmempoolancestors, getmempooldescendants, getmempoolentry, getrawtransaction, decoderawtransaction, gettransaction, listtransactions, listsinceblock;
  • addlocked param added to getreceivedbyaddress, getreceivedbyaccount, getbalance, sendfrom, sendmany, listreceivedbyaddress, listreceivedbyaccount, listaccounts.

There are also new RPC commands:

  • protx (list, info, diff, register, register_fund, register_prepare, register_submit, update_service, update_registrar, revoke);
  • bls generate;
  • setprivatesendrounds;
  • setprivatesendamount.

See help command in rpc for more info.

Command-line options

New cmd-line options:

  • masternodeblsprivkey;
  • minsporkkeys;
  • privatesendsessions;
  • zmqpubrawinstantsenddoublespend;
  • zmqpubhashinstantsenddoublespend;
  • zmqpubhashgovernancevote;
  • zmqpubhashgovernanceobject;
  • zmqpubrawgovernancevote;
  • zmqpubhashgovernanceobject.

Some of them are Devnet only:

  • budgetparams;
  • minimumdifficultyblocks;
  • highsubsidyblocks;
  • highsubsidyfactor.

Few cmd-line options are no longer supported:

  • instantsenddepth;
  • mempoolreplacement.
