VNL, really? Why you think that?
I ask because read a lot of complaints about double-spending, code problems and things like that.
XVC has never had a double spend or had code problems. There are some that worry about its instant transactions because John-connor refuses to release a full whitepaper describing how he has solved the byzantine generals problem, but no instant transfer coins have solved that problem yet.
On the other hand xvc is the only other coin besides btc that polo will accept with 1 confirmation, so it is the fastest coin to exchange coin.
Other than that the code problems were accusations of copyright infringement because John-connor didn't add in the appropriate acknowledgement to bitcoin/peer coin while referencing their code.
In his 1 year timeliness he does indicate that he will have all copyrights in place before moving out of beta so this too will be a moot point by then.
