Yep, we've completed the phase 1 hard fork to move SPL to a new codebase and enable multi algo PoW/PoS/MN, but progress on phase 2 of the upgrade is moving slowly as I'm the only developer contributing to the project currently. I am more active in the project discord, so it's usually a better place to check for updates.

Alternatively, you can always find the latest release on GitHub:
https://github.com/simplicity-coin/simplicity/releases

We're collaborating with the developers of several other coins using the same wallets to move to the PIVX codebase (which will enable blockchain governance, atomic swaps, and the lightning network) and I can work on adding segwit after the fork, but we need to come together as a community and decide where we are going to go after this. I have also contacted a CoinExchange representative about additional pairings but haven't received a response. We will likely pursue a crypto-bridge listing after the hard fork and/or rebrand.

Sorry, but you are mistaken. The development and community of this coin is still very much active, but we are providing all status updates through discord currently. My latest wallet release (v1.2.2) is stable and works quite well and we have a hard fork + supply reduction in the works.

v1.2 release is out

Yes, we've been discussing this in discord and it seems to be due to the automatic darksend coin mixing that occurs in the background. The v1.1+ wallets have a new darksend protocol that is incompatible with all the v1.0 masternodes people are running (the wallet keeps trying to connect to MNs to process darksend and if it can't find a v1.1+ MN to process it properly the wallet hangs) so it seems the only solution for now is to get MN operators to update or use the wallet litemode which disables darksend. I'm breaking compatibility with v1.0 in v1.2 to force MN operators to upgrade but first we need CoinExchange and masternodes.online to get on board with the update so I'm waiting on Delaforetnoire to get back to me about what's going on with them.

Delaforetnoire is handling all of our communication with CE now, so he would be able to provide updates on a Doge pairing. Right now I'm pushing another update to reduce the target peer connections so that the wallet won't lag/crash/use so much CPU time looking for 64 other nodes to connect with.

I have taken over development for the moment and we should have a new wallet out shortly.

Great to see the active development and daily updates on GitHub

This guide is written for another coin but it works for Simplicity

For what it's worth, I set up another Simplicity block explorer with up to 500 transactions indexed on every address:

The more the merrier, right?

Whoa there buddy, no need to monopolize the MN network this early on

Awesome

I got it to work by running these commands before launching the daemon:
But I agree, the build docs should definitely be updated
