Bittrex has locked out deposits and withdrawals (but not trading) of ZEN and ZCL due a vulnerability related to the split from ZCL to ZCL and ZEN. Bittrex is the primary exchange for them. The lead developer has left the project.
The nature of this type of attack, called a replay attack, could lead to a transaction replaying from the Zclassic blockchain to the Zen blockchain if the vulnerability is exploited.
ZEN company has thanked the lead developer for making the vulnerability public and bringing it to their attention at the same time he quit the project. I’m not trying to be sarcastic I’m just relaying their announcement. I haven’t found his public comments, so I don’t know if it was a rage quit.
ZCL seemed to get off to a good start on the appeal of not being directed by a company that receives coins. It was billed as ZEC without a “pre-mine”. Up until the split was announced, ZCL was beating ZEC on appreciation rising over 20x from December to May. ZEC has risen only 10x from it’s absolute brief low to its high.
But then they decided the no-profit route just did not cut work and split it into ZEN with no pre-mine, no ICO, etc and yet if you look at the breakdown of where coins go, 12% go places other than mining. If that’s for the life of the coin, then I think that’s more than ZEC takes.
There was talk that the split to ZEN enabled a lot of insider profits to be made by buying ZCL before the announcement.ZCL dropped immediately as ZEN trading became available. Now I’m wondering if an insider who may have returned to buying ZCL before this announcement is going to get a boost, especially if he soon publicly returns to ZCL.
