I get what you are saying and I agree with you that there is a disconnect between expectations and progress. Most alt coin projects are work in progress including xzc and the recent bull market has increased the expectations on everyone to perform and deliver.
That said, the MTP is a huge undertaking and probably the most difficult project detailed on the roadmap. It is probably compounded by the presence of sync issues which is just as important to fix and previously, our development team was perhaps over-stretched.
I think what matters over the past couple of months is honest communication from marketing and on the development side, the zcoin team has expanded the developer team and added a cryptographer to increase our capacity to deliver - you should be able to see our increasing level of activity here.
We have an ongoing miner competition and other initiatives to encourage the participation of the developer community to make sure our implementation is water-tight.
Our marketing activities revolves around getting the importance and significance of our project out to the public and we are very careful that it does not cause over expectation which ultimately leads to disappointment - this is why we have kept everyone in the loop on what's happening.
We thank you and the community for your support and we understand we can do better. The Zcoin project remains an important project for bitcoin anonymity and decentralisation - and we are fully committed to deliver according to the roadmap.
Excitement about "MTP" which has been promised for months, and was promised to make GPU/CPU competitive - see
https://zcoin.io/what-is-mtp-merkle-tree-proof-and-why-it-is-important-to-zcoin/ (they're not, GPU is 3x) - might be wearing a bit thin.
A few pages back on this thread you'll see MTP was exposed as fundamentally not memory hard by disgruntled a miner developer who complained of inexplicable code changes, and Zcoin then said, 'oh yeah we changed it because it had a bug and wasn't memory hard'.
Zcoin's history unfortunately is littered with great promises, but then when the Christmas pudding is finally put on the table, it's small, burned, and strange tasting. Devs are good guys trying to make it work, but marketing gimmicks to paper over a lack of working product won't cut it, and I think there's a lack of trust in Zcoin in the investor community.
(Zcoin underperformed the altcoin market before and during the recent crash. Substantially.)
I can't spend my whole day here arguing. I'm just expressing my genuine belief. I am not even saying that Zcoin has no future, I'm saying that this news on MTP is massive, will massively weigh on prices, and is a very big setback and adds to reputational concerns around Zcoin.
It will not, you just need to read what is written, as you the only one who keeps pushing its own truth create in parallel reality.
