The hacker used a bug in the blockchain Bitcoin, which was discovered on 18 September, issue 235 million tokens Pigeoncoin (PGN) in the amount of about $15,000. The developers of blockchain startups patched the system and eliminate the vulnerability of the network.
A bug that allows you to generate new coins can be used almost in every blockchain, so the creators of cryptocurrency projects hastily carried out a system update to address the vulnerability of the network. However, the situation is not so dangerous as it might seem: the"extra" digital assets are destroyed, so the total number of coins in circulation will not change.
Cryptocurrency Pigeoncoin is not the most popular, in terms of capitalization tokens are not included even in the top 1000 of the virtual currency. At the time of a hacker attack, the total number of coins PGN was $ 970 million, thus the attacker was able to "print" almost a quarter of the total number of assets! And if this happened with Bitcoin?!
The only exchange on which trade is conducted, tokens Pigeoncoin, CryptoBridge has suspended all trading operations in cryptocurrency pairs with PGN to eliminate the bug. Project developers quickly patched the system and asked mining pools and cryptocurrency exchanges to update the software.
Many cryptocurrency startups have already conducted an upgrade of their blockchains, including Gold, Bitcoin, Ethereum, Bitcoin and Litecoin cash, so the possibility of recurrence of such incident in the network leading digital asset is excluded.
