Unfortunately, no advantage of this was taken.
Because our dev couldn't bear with the criticism they had from the community. Despite they had ban a lot of users for small issues which shut all the mouths. We could have done a lot of steps at that time.
BTW, I found another competitor of DeepVault, it's called Silent Notary. Seems that the competition in blockchain notarization will be strong in the future. DeepOnion should find some marketing guru soon, before it's too late and the market is split among other projects.
They are listed on Kucoin and Hotbit, seems far better than our listed exchanges. I don't know how much real life usages they have. Since they are dedicated project to notary system, I think ONION will have so hard times soon to compete on the market.
