4. Parity Wallet Freeze
Possibly the year’s greatest protection incident, this entry on the list is also distinguished by remaining 1 the couple to just take area with no the obvious help of a destructive party.
Occurring instantly this November, a Parity person accidentally found a bug in the program code, freezing additional than $275 million in ether in the wallet’s next important incident of 2017.
A single of two widely made use of clients for ethereum, the miscue effectively referred to as into concern what was and is a central infrastructure element of the community, prompting some to question the firm’s choices and renewing criticisms of ethereum alone.
