The bugs were in the "confidence" and "doublespend" api of blockcypher.
they advertise that as a safe way to accept quick btc transactions.
services like shapeshift, btc gambling casinos were using it too, i was feeling safe.
it was tested a lot and 100% working, this loss was not possible if blockcypher had 0 bugs.
blockcypher api for 1 hour flagged ALL transactions as safe to accept with high confidence.
during that hour someone attacked my services (digital items shop and one like shapeshift)
and stole 7 btc worth of crypto/items with doublespends.
I contacted blockcypher support in less than 1 hour and as soon as i contacted them the bug
was closed, they denied everything and now ignoring me completely.
i suspect one of them bugged the api and stole from my services, then closed the bug as nothing happens.
perfect heist if you guys think about it: you are working at blockcypher and do this:
bug api on purpose -> steal from services using the api -> restore api and close bugs -> deny everything, keep money.
under normal circumstances (no bugs in blockcypher) this happens on my services:
user tries to double spend -> blockcypher api warns about that -> my service does not accept payment.
so as you see no harm was possible
All the proof i have are all the email messages between me/blockcypher with all the details on this issue, all the tokens
used and some of the affected transactions id. those txid are now gone from the network, i get not found on blockchain but they were there when this happened (double spends). im willing to give moderators full access to email account messages.
Im 100% open to prove im real and not a random guy asking 7 btc for no reason..
i just want them back from them, is the right thing. this is ruining my life dammit i have 4 kids what can i do now.
on top of this someone is trying to extort 0.5 btc from me to get my 7 back. its a lie of course, he claims to work for blockcypher.. if thats true this makes them the devil, its a very red flag.
i paid top dollar for premium services with them in the past, over 5000$ and this is the treatment i get now. i feel very bad
please help, i also posted in scam accusations
