TL;DR: Crypto Dev Digest (CDD) is a regular column, documenting cryptocurrency development, highlighting the projects and persons working under the hood. Bitcoin Cash-based RealmX gets a thorough gameplay review. EOS creator claims to have solved vote-buying issues. Ethereum co-founder gives a tutorial on understanding PLONK. Where2Cash is moving along. November BCH upgrade includes plans for Schnorr. ProgPoW advocate and CTO of Core Scientific steps down. Lightning Network bug’s fallout, and a tons more in this week’s Digest.

RealmX Gameplay Review

John Moriarty of Bitcoin Out Loud gave a recent, jeweler’s eye review of the Bitcoin Cash-based game, RealmX. It’s a neat look inside a very, very early rendition leaked to the public. That’s important to note: this is not an official, ready-to-ship version. But it is out there, and Moriarty gives a fair, thorough examination. Oh, and it’s called Realm Ten, not Realm Ex. Again, this isn’t even close to a final version, so to keep up with the latest, follow the RealmX team on Telegram.

Amazing Solution to EOS Vote Buying

Today Brendan and I came up with an amazing solution to vote buying that will completely remove the incentive to buy votes. #eos governance will be decentralized, resources will be cheaper, and incentives will be aligned! More to come! — Daniel Larimer (@bytemaster7) September 23, 2019

Schnorr After Multisig is Enabled

Developer Antony Zegers tells CoinSpice, “There’s a PR ready to mark Schnorr ‘complete,’ but it’s deferred until after Schnorr is enabled in Multisig. This will happen in the November upgrade,” and pointed to this GitHub.

Core Scientific CTO Resigns

Today, I announce that I have stepped down as CTO of Core Scientific. I believe that ProgPoW is of such importance to ETH's transition to ETH 2.0 that I felt removing any potential conflict or professional associations was important. — Kristy-Leigh Minehan (@OhGodAGirl) September 24, 2019

More LN Bug Fallout

People were unknowingly accepting Lightning bitcoins that weren't actually backed by real bitcoins. These people wouldn't even find out until they went to withdraw their coins from the Lightning Network (i.e., close the channel). 1/2https://t.co/K3ZnqibeLj — Peter R.

No One Should Use the Dash Wallet From DashPay

No one should use the $Dash Wallet from @Dashpay. They can't design good software. It looks cheap and has irritatingly poor usability. 💩 Use the @EdgeWallet instead — multi asset (Dash, ETH, BTC…), username & password, built-in exchange, and way more polished! 🏆 pic.twitter.com/LCLVaxvyub — Dash Crypto (@dashcrypto) September 27, 2019

Bitcoin Cash Does Not Use DigiShield

DigiByte facts are fairly undistinguishable from fiction. Bitcoin Cash uses a moving average based of hashrate and compute the difficulty from it. It doesn't use DigiShield. https://t.co/vVFAiZkf0k — deadalǹ͔͜͡i͎̜͖͗̎͞x̛̳̠̤̥̦̉̊̕̕ (@deadalnix) September 28, 2019
