A hack on the Ethereum blockchain in the summer season of 2016 resulted in $60 million well worth of ether staying stolen. The occasion sparked enhanced focus to cybersecurity pitfalls connected with blockchains, particularly for cryptocurrencies that may perhaps have large value mainly because they are not subject to govt or economical establishment handle.
The challenges of blockchain hacking.
