I am a little investor of AGS and PTS, I have an idea about how to reduce volume of block chain using snapshot,  English is not my native language , I hope I can been understood.
1.   The purpose of snapshot in my express is different from normal , this snapshot is to replace blocks before them to reduce this size of block chain.
2.   Perform a snapshot per N block; and the next block is a special block , its header include the hash both previous block and this snapshot.  We also can set the confirm time of this block is longer than others, maybe need  all delegates honored.
3.   Each block after this snapshot include the status if honor this snapshot.
4.   Each translation include the status if honor this snapshot
5.   if the snapshot was honored by N block, and was honored by translation witch hold 90% stockholder , this snapshot is a formal snapshot.  The blocks before this snapshot can been ignore . ignore the blocks before this snapshot have risk ,so there have N block time to check if there is no attack/ scam in the snapshot ,  if  select N equal 100,000, it mean , every delegate check this snapshot 1000 times if there are 100 delegates, and every client also check this snapshot when a translation is done, and the meantime ,any node can select to keep all block for checking.
6.    If all process was finished smoothly, block chain only include a snapshot +N blocks no matter how many years this chain have been running , the volume of a snapshot maybe is constant,   if N equal  100,000, consider 30 sec per block , it is about 34 days , so all the size of block chain is equal a constant volume  +  volume of 34 days translation. It doesn’t increase as time passing  .

Solid idea.  The challenge is in defining what to include in the state and how to download it.   With DPOS we have some options not available to other systems, but it is still challenging.

如果单说me，我认为是基础货币的价值是通过应用性来体现的，而不是mecoin先有了价值后才能吸引别人来发行资产。只要系统稳定，发行方完全不必在意mecoin的市值，因为他只是用这个系统管理股份而已，这只是一个工具。其实比特币也有类似的意思，大家渐渐认识到了他的支付功能，所以比特币才升值了，而不是比特币具有比较大的价值了，才吸引别人用它来作为支付方式。

现在其他的二代币大多采用的是一个基础货币内建各种功能（如交易所，资产发行，博彩），这和3I的模式很不同。3I的比较松散，可以各自发展，他的联系主要还是靠BTA来完成。从逻辑上其实两者差不多。3I的模式给了每个DAC更大的自由度，说无意义可能有点言之过早，孰优孰劣还需要检验，其实我还是觉得3I的这种模式更清晰些，各种DAC的主货币担负着“独特的”价值承载功能。而一个主货币支撑所有应用的价值，我感觉是比较乱。

Also all nodes and all traffic is encrypted so you would have to be directly connected to a node to find out if they are the one to produce the block and they might not even be the one that produced it they could just be the first one to have received it.

Your attack requires cooperation of shareholders to give up their original keys....  it is not worth considering if there is a large number of initial shareholders.
