Wow, I haven't checked on the forums in a while and... what a train wreck. Here are the main issues with this proposal:
1) There is no fair method of consolidating multiple blockchains. At
best, 50% will lose and 50% will gain.
2) Further to #1, emski is right about this:
https://bitsharestalk.org/index.php?topic=10189.03) AGS received a much larger allocation of DACs per dollar invested precisely because they are "locked" into the Bitshares ecosystem. Making them liquid after the fact is unfair. It essentially gives AGS holders all of the benefits of PTS without any of the downside. Here is the "company" analogy we like to use so much: The Bitshares Corporation gives investors a choice between buying one of two corporate bonds, A and B. Bond A is perpetual and bond B is convertible. For this reason, A has a much higher yield than B. After the bonds are issued, the company turns around and says "just kidding," A is now also a convertible bond, though it keeps the higher yield. Just something to think about.
I have a counterproposal: fork all of the other DACs (except AGS) and create a system for "merge mining" them with BTSX. This way they stay on their own blockchains but use the single set of delegates from BTSX. We'd have to resolve the burn rate issued and they can be given the option to vote away from merged mining at any time. This solution keeps the allocations and blockchains the same (no complaints from anyone about "fairness") but consolidates delegates.
