Financial report for Nov 2020 is attached.

While preparing 4.0.4 release (which is a major update), we've encountered many minor issues on both desktop and android client, so the release is somewhat delayed. We hope that we'll be able to release testnet version for beta testing next week and the mainnet version for public use one week later.

Finally, we've released 4.0.4.1. This is a major upgrade. BACKUP YOUR WALLETS before updating.

Changes:

  • Partially Signed Bitcoin Transactions (PSBT, BIP-174) are supported
    (#5721). The previous Electrum partial transaction format is no
    longer supported, i.e. this is an incompatible change. Users should
    make sure that all instances of Electrum they use to co-sign or
    offline sign, are updated together.
  • Hardware wallets: several fixes in general; notable changes:
  • Compatibility with latest Trezor fw (#6064, #6198, #5692)
  • Dependencies (see README for install instructions):
  • libsecp256k1 is now required (previously optional). python-ecdsa
    remains a dependency but it is now only used for DNSSEC.
  • Added: either one of pycryptodomex or cryptography is now required,
    mainly due to LN (previously pycryptodomex was optional, for fast AES)
  • Removed: jsonrpclib-pelix, the JSON-RPC library used for CLI/daemon
  • Qt GUI: several changes, notably:
  • Separation between output selection and transaction finalization.
  • Coin selection moved to the Coins tab, and it affects all txns,
    e.g. RBF fee-bumping, LN channel opens, submarine swaps.
  • Editable tx preview dialog that allows e.g. changing the locktime
  • Android:
  • The kivy GUI now supports importing BIP39 seeds
  • Each wallet on kivy now can have a separate generic password,
    using which the wallet files are encrypted. An optional PIN,
    shared among all wallets, can be added to get prompted for spends.
  • The API of several CLI/RPC commands have changed, and several new
    commands have been introduced (mainly for LN).
  • Distributables:
  • Apple. Min macOS version is 10.13.
  • Transactions:
  • we now grind low R for ECDSA signatures to match bitcoind (#5820)
  • Lots and lots of other minor bugfixes and improvements.
  • Hardware wallets:
  • run all device communication on a dedicated thread (#6561).
    This should resolve some threading issues.
  • new feature: "Automated BIP39 recovery" (#6219, #6155)
    When restoring from a BIP39 seed, add option to scan many known
    derivation paths for history, and show them to user to choose from.
  • show derivation path of keystores in Qt GUI Wallet>Information (#4700)
  • fix "signtransaction" RPC command (#6502)
  • Dependencies: pyaes is no longer needed (#6563)
  • Ledger: fix "The derivation path is unusual" warnings (#6512)
    (needs Dash app 1.4.8+ installed on device)
  • Legacy masternode modules was removed since unused

I see the beam desktop wallet does beam-dash atomic swaps. It recommends electrum though I'm sure it works with the DCG wallet too.

https://www.reddit.com/r/beamprivacy/comments/kf0yyb
I guess it's a little unnecessary to also do this from dash electrum but OTOH maybe these extra privacy features bring a certain type of user to dash electrum? I mean, the more dash electrum differentiates itself from the DCG wallet, the more users it's going to get. Or maybe there is a way to simplify the atomic swap process further, like some kind of automatic pairing? - I haven't really thought that part through but maybe it gives you some ideas.

Anyway, I'd be interested to see extra privacy features that DCG is unwilling to put in their own wallet.

Thanks

Missed this post, while working on 4.0.x releases.

We'll definitely consider putting it on our roadmap.

Any thoughts on porting Payment Channels / Lightening Network to work with Dash Electrum?

  • increased privacy
  • demonstrating that dash is not entirely dependent on masternodes
  • potential for cross chain swaps via LN on other networks

I've thought about this. This won't be an easy effort, even taking into account that heavy lifting was done by Bitcoin Electrum team. So first we'd do some work on alternative ways to do coinswap (see https://github.com/akhavr/electrum-dash/issues/197 for example) and then will proceed with lightning.

Note that crosschain swaps are difficult beasts: they're not used even in Bitcoin LN.
