A hack on the Ethereum blockchain in the summertime of 2016 resulted in $60 million truly worth of ether currently being stolen. The party sparked amplified notice to cybersecurity threats linked with blockchains, especially for cryptocurrencies that may well have large price because they are not issue to govt or money institution regulate.

Alone assault that could have benefit for hackers even if it does not direct to the collapse of a blockchain system would be just deleting details from the ledger alone.
