@litecoincash-project litecoincash-project released this Feb 11, 2020

This is mostly a quality-of-life release, but due to a fix for an occasional Hive checking issue is strongly recommended for all beekeepers.

  • Added maxoutboundconnections commandline/config argument. Defaults to the previously hardcoded value of 8.
  • Fixed intermittent startup crash observed on fast machines with SSD chainstate
  • Fixed MacOS UI scaling issues
  • Hive tab layout tweaked to allow full wallet display on lower-res screens
  • Fixed incorrect ICC profiles in PNGs
  • Fixed occasional binning issue

This release brings the power of multi-threaded hive checking to the core wallet. It does not change consensus rules, but is strongly recommended for all beekeepers.

In addition, new early-abort tests ensure that your hive won't waste time working on a stale block when it could be trying to find a fresh one.

Three new command-line/config-file parameters are available:

-hivecheckdelay : Time between Hive checks in ms. This should be left at default unless performance degradation is observed (default: 1)

-hivecheckthreads= : Number of threads to use when checking bees, -1 for all available cores, or -2 for one less than all available cores (default: -2)

-hiveearlyabort : Abort Hive checking as quickly as possible when a new block comes in. This should be left enabled unless performance degradation is observed. (default: true)

These options can also be checked and set via new RPC commands gethiveparams and sethiveparams (see full RPC documentation at https://hive.litecoinca.sh/rpc/).

In 99% of cases, the default options should work fine for you.

Multithreaded hive checking does not depend on any particular distribution of bees across BCTs. All bees are pooled together and then binned into threads, so it doesn't matter if you have a large number of low value BCTs, a small number of large value BCTs, or any mixture -- you still benefit from the same speedup.

Special acknowledgements for this release go to the LCC Release Staging team, and particularly DOTTAT and rabTAI for extensive testing and feature ideas, and to uross for building Pi binaries.

This update is recommended for QT (desktop) wallet users on all platforms.

It provides correct GI and honeypot display either side of Hive 1.1 activation, with thanks to DOTTAT.

Thanks to uross for the Raspberry Pi builds.

This release resets testnet again to introduce further improvements to Hive 1.1's hivediff adjustment algo.

It's a non-essential release unless you're a testnet user.

For the first time, we're proud to provide Raspberry Pi binaries (with thanks to uross).

For most, this is a NON-ESSENTIAL release (unless you would like to take part in upcoming wargames on testnet).

This wallet updates the existing Hive 1.1 ruleset on testnet. For full details of Hive 1.1, see previous release: https://github.com/litecoincash-project/litecoincash/releases/edit/v0.16.0.6


  • Network hash estimate accuracy increased

  • Completely rewritten hive difficulty adjustment allows 50:50 hive:pow ratio

  • Testnet and mainnet hard nodes updated

  • Fixed #19 (Creating Bees with a Honey Address outside of your wallet does not give error)

  • Additional check for illegal scriptPubKey length in BCTs

  • Bees now make sure they haven't mined on a stale tip before submitting blocks

  • Hive mining optimisations, for beekeepers of all weights

  • createbees and createrawbct RPC examples now using a mainnet address

For most, this is a NON-ESSENTIAL release (unless you would like to take part in upcoming wargames on testnet).

This wallet allows Hive 1.1 UASF activation on testnet. Additionally, a new createrawbct RPC call allows integrators full coin cointrol when creating bees (see https://hive.litecoinca.sh/rpc/).


Hive 1.1 introduces a dynamic chainwork bonus parameter (the k parameter in Section 5 of the Hive whitepaper). This enables Hive to protect against strong (300%+ of mainnet) PoW attackers.

As well as awarding additional bonus chainwork to Hive-mined blocks, Hive 1.1 awards a chainwork bonus to PoW blocks following them. This bonus is maximised when block types are in alternation. This enables the two different mining dimensions on LCC to work symbiotically and ensure that a privately mining pure-PoW miner cannot get ahead of the public chain.

Additional measures ensure that a multidimensional attacker would not be able to privately mature bees on a withheld chain ("stealthy bees" attack), nor would they be able to effectively use publicly matured bees on a withheld chain ("lazy bees" attack) to gain the chainwork bonuses.

A further effect of Hive 1.1 changes in a non attack scenario will be to prevent shallow Hive blocks being reorged by PoW blocks, ensuring that Hive blocks always have higher priority. This will serve to move the ratio of PoW:Hive blocks closer to the ideal 50:50.

Hive 1.1 and its defence against these three classes of attack (pure pow, privately matured bees, and publically matured bees) will be further explained in a forthcoming whitepaper.

This is a non-essential upgrade, but it strongly recommended for Hive miners as it corrects the GI metric to reflect observed real-world conditions.

It also rolls in various Hive RPC additions implemented since the last public release (See https://hive.litecoinca.sh/rpc/ for an always-maintained guide to Hive RPC calls).

You MUST ugprade if you are running v0.16.0.1 or below.

If you are already on v0.16.0.2, this is a non-essential upgrade.
