Hi. When will happen the change of algorithm? I mean the code. And we need to send our coins from wallet to an address and get new coins like happen when pass to xevan algorithm?
You meant swap. I actually swapped my Solaris coins from NIST5 algorithm to Xevan algorithm in the year 2017. The Solaris team built a page to do the swap, automatically, and swap process done very fastly. For the coming source code changes from PIVX source code to Stratis source code, by now I have not heard Solaris team mention about swap. Let's wait more details later.
There will indeed be a swap for this new codebase, and it will utilize the similar page to do it automatically. We don't have an exact date yet, but it will happen in the next 2 to 3 months probably, and the swap period will be at least 6 months.
