Krypton Abandons Ethereum for Bitcoin Proof of Stake Blockchain after 51% Attack
Krypton, an Ethereum-based blockchain, has announced that in order to protect its token coin KR from being stolen from exchanges through a double spend it has decided on a temporary course of action.
In an announcement today, founder of Krypton Stephanie Kent said:
Krypton is moving KR from an Ethereum-based proof-of-work blockchain to a Bitcoin-based proof-of-stake blockchain.
The 51% Crew
Last month, the Krypton blockchain was attacked twice by an anonymous group known as the 51 crew.
They were able to utilize a deadly blockchain exploit that was a two-step attack. The first step was overpowering the network with at least 51 percent of the hashing power to enable a roll back on transactions, and subsequently spending the same coins twice. The second step was employing DDoS nodes to increase network power.
