HSD Release Notes & Changelog

v2.4.0

Chain & Consensus changes

  • A consensus inflation bug has been fixed. Non-upgraded miners should upgrade as soon as possible. See https://handshake.org/notice/2020-04-02-Inflation-Bug-Disclosure.html for more information.
  • A new chain value migration is necessary (related to the above fix). This migration will automatically run on boot and should only take 2-3 minutes. Pruned nodes cannot run this migration. Note that pruned nodes may have an incorrect chain value until they re-sync.

Mining changes

Wallet changes

  • Fixes a bug that caused rescans to fail if a name being "watched" was ever TRANSFERed. A deepclean plus rescan may be required to fix affected wallets.

DNS changes

  • Root server DNSSEC has been fixed. It is only authoritative over DS and TXT records, and only returns TXT if no NS (referral) is present in the zone.

Node changes

  • FullNode and SPVNode accept configuration parameter --no-dns (or no-dns: true in hsd.conf) which launches the node without either DNS server (the root authoritative server and the recursive resolver). This avoids some port collisions with other HNS resolvers like hnsd running locally, and generally separates and reduces security concerns around running unneeded servers when a node is just used for transactions and blocks. --no-rs is also accepted to disable the recursive DNS resolver (but keep the root server).

Wallet API changes

  • Adds new wallet HTTP endpoint /wallet/:id/auction based on POST /wallet/:id/bid. It requires an additional parameter broadcastBid set to either true or false. This action returns a bid and its corresponding reveal, the reveal being prepared in advance. The bid will be broadcasted either during the creation (broadcastBid=true) or at a later time (broadcastBid=false). The reveal will have to be broadcasted at a later time, during the REVEAL phase. The lockup must include a blind big enough to ensure the BID will be the only input of the REVEAL transaction.

  • Now parses option --wallet-check-lookahead (or --check-lookahead for standalone wallet node) that will check every account of every wallet in the DB and ensure the lookahead value is the current default and maximum of 200. A rescan is recommended after this action.

Node & Wallet API changes

  • The stats field included in namestate.toJSON() includes extra data if the name is in a TRANSFER state.

v2.3.0

Node changes

  • FullNode now parses option --min-weight=<number> (min-weight: <number> in hsd.conf or minWeight: <number> in JavaScript object instantiation). When assembling a block template, if there are not enough fee-paying transactions available, the miner will add transactions up to the minimum weight that would normally be ignored for being "free" (paying a fee below policy limit). The default value is raised from 0 to 5000 (a 1-in, 2-out BID transaction has a weight of about 889).

  • Transactions that have sat unconfirmed in the mempool for 3 days will be evicted. This is the default MEMPOOL_EXPIRY_TIME value set in policy.js but can be configured (in seconds) with the FullNode option --mempool-expiry-time.

Wallet API changes

  • Adds new wallet HTTP endpoint /deepclean that requires a parameter I_HAVE_BACKED_UP_MY_WALLET=true. This action wipes out balance and transaction history in the wallet DB but retains key hashes and name maps. It should be used only if the wallet state has been corrupted by issues like the reserved name registration bug or the locked coins balance after FINALIZE bug. After the corrupt data has been cleared, a walletDB rescan is required.

Node API changes

  • Adds new wallet HTTP endpoint /deeprescan that requires a parameter I_HAVE_BACKED_UP_MY_WALLET=true. This action wipes out balance and transaction history in the wallet DB but retains key hashes and name maps. It should be used only if the wallet state has been corrupted by issues like the reserved name registration bug or the locked coins balance after FINALIZE bug.

Wallet changes

  • Fixes a bug that ignored the effect of sending or receiving a FINALIZE on a wallet's lockedConfirmed and lockedUnconfirmed balance.

v2.2.0

Upgrading

This version fixes a bug in the wallet that would corrupt the database if a user manually generated change addresses using API commands. Upon running the updated software for the first time, hsd will check for corruption and if there is none, proceed with normal operation (no user interaction is required, although this process may take a few minutes for a "busy" wallet). If the bug is detected, hsd will throw an error and quit. To repair the wallet, the user must launch hsd with an extra command-line flag, in addition to whatever parameters they normally use:

$ hsd --wallet-migrate=0 (for most users)

or $ hs-wallet --migrate=0 (for remote wallet node)

These flags may be added to environment variables or a config file if desired, following the pattern described in the configuration guide.

The repair may take a few minutes and will automatically initiate a rescan. For this reason, the user's wallet MUST be connected to a full node (not a pruned node or SPV node).

Node API changes

  • Adds a new node rpc resetrootcache that clears the root name server cache.

  • A new RPC call validateresource was added to validate Handshake Resource JSON and will return an error message on an invalid Resource. The input JSON object is the format expected by rpc sendupdate.

  • A new RPC call getdnssecproof was added to build and return the DNSSEC proof used for reserved name claims. This can be used to test if a reserved name is ready for a CLAIM.

  • RPC calls that return tx outputs in JSON now include output addresses as a string in addition to the version/hash pair.

  • RPC methods getblock and getblockheader now return confirmations: -1 if the block is not in the main chain.

  • A new HTTP endpoint /header/:block was added to retrieve a block header by its hash or height.

Wallet API changes

  • Adds new wallet rpc importname that enables user to "watch" a name and track its auction progress without bidding on it directly.

Wallet changes

  • A bug was fixed that prevented reserved names that had been CLAIMed from REGISTERing. If unpatched software was used to CLAIM a name already, that wallet database is irreversibly corrupted and must be replaced. See handshake-org#454

v2.0.0

Wallet API changes

Creating a watch-only wallet now requires an account-key (or accountKey) argument. This is to prevent hsd from generating keys and addresses the user can not spend from.

v0.0.0

Notable Changes

  • Initial tagged release.
