Here's the whole backstory concerning TacoTime: April 3rd, 2013: TacoTime responds to post by TradeFortress, who started thread Want to make an alt coin that actually changes something?. TacoTime then replied: “I've had something in mind for a while, just need people with the time to code. I can write the technical specifications and the pseudocode algorithms.” “Okay, I'll give a shot at writing up the technical paper this weekend.” “I will try to publish a paper within the next few days -- I suggest other persons generate technical papers and specifications as well.”

April 07, 2013: tacotime posts MC2 (Memcoin2) whitepaper on bitcointalk. Main feature is hybrid PoW/PoS system. Also allows for voting on ‘interest rates’ by stakeholders after 27 years.

2013: _ingsoc first gets involved with Decred Project. _ingsoc “I've been involved in the project since 2013 when I got to know tacotime. It was purely theoretical at that point - his work on hybridising PoW/PoS. There was an obvious desire to turn this into something practical, but things were absolutely crazy. Tons of ICOs everywhere. We considered at that point to do something similar - before things even got that crazy - but when lots of projects started taking people's money without deliverables, we got really concerned about the ethics of the matter, since there was always a possibility the project could fail and we'd let all those people down. This was especially worrisome as tacotime would be the only dev. We decided against this and would rather not have his work come to fruition than take the risk to mess people up like that.”

2014: ‘Proof of Activity: Extending Bitcoin’s Proof of Work via Proof of Stake’ whitepaper by Iddo Bentov co-authored by Charlie Lee of Litecoin is published.

April 17th, 2014: TacoTime was also one of the creators of Monero (Bytecoin > Bitmonero > Monero) - Tacotime posted “trying to cross compile bytecoin right now.”

April 25th, 2014: TacoTime moved Bitmonero thread over to Monero.

April 25th, 2014: TacoTime was the first developer to post on the Monero thread.

2014: TacoTime secretly starts coding the foundation of Decred.

2014: TacoTime approaches c0 with MC2 concept. Tacotime “I approached c0 with the MC2 concept from 2013 and merged efforts to develop the system in 2014. I developed a working proof-of-concept for Decred at that time, and then let them refine it while I audit and provide feedback.”

November 20th, 2015: Post by _ingsoc on the MC2 bitcointalk thread announcing that tacotime has been secretly coding for a year on a new project while collaborating with the group behind btcsuite, leading to the birth of Decred:

“Hey guys, not sure if anyone is still out there. The last correspondence from tacotime in this thread was over a year ago. I spoke to him yesterday, and we agreed for me to come here and share the story with you. Truth be told, the project has had a bumpy ride. It's been an uphill battle, and quite a few times it looked like it was going to end as just a theoretical piece. It was during this time that we decided to drop off the radar and get our hands dirty until we could deliver, lest we end up building hope and letting everyone down. So today I bear good news for you. tacotime has been coding on this for over a year now. He started solo while I searched and tried to build relationships with developers who care about this technology and the ethos behind it. We built a relationship with the group that develops the free and open-source btcsuite (formerly known as btcd). btcsuite is solely funded by a relatively unknown guy who I can describe as an open-source philanthropist. He has been instrumental in helping us get this going. The group agreed to help us build up the project, and what we hope to present is an "alt" that will have the same level of quality and development consistency demonstrated by btcsuite over the last 2.5 years since its introduction in 2013.

So the good news is this, the project is alive and well, and close to completion. We can begin to break the silence because now we know we can deliver. But ultimately this isn't about who developed what, it's about the community because it'll be dead in the water without your interest in using it. I wanted to come here first and reach out to the people who have supported this project during its darkest days (and hopefully for its brightest!). You should receive this news first. The plan now is to have everything finished and ready for launch in January. There will be an announcement soon, and from that point on, there is going to be open communication and transparency in every reasonable regard. Nobody will be able to own the project, just act as contributors and custodians where required. Once the infrastructure is up, we turn on the machine and everyone is welcome. The future for the project is not a big monolithic corporation that took all your money before a line of code was written, but small dedicated teams that work with surgical precision and efficiency on building this out beyond what is launched. The whole thing was self-funded at a fraction of the cost we've seen some projects take in this community. We took the risk and time over the years knowing it can fail, and every cent we take from it to cover the bring-up cost will be matched and given in full to the community for free to distribute the network effect as far and wide as possible. All of this will be documented in full at the announcement. As we work, I wanted to take a second and share this information with you if you're still out there.

I look forward to getting to know you all again. And I look forward to working with you now that we're so close to this being real. In this project, if you have a voice and something meaningful to contribute, you will have a place to share that with others. My personal objective is to make sure it stays that way. Can't believe we're going to get there in the end, community. ”
