Cardano, a prominent public blockchain network, has processed over 20 million transactions in a row without experiencing any downtime. This is a once-in-a-lifetime milestone for any Proof-of-Stake blockchain network.
Cardano pulled off the remarkable achievement despite being derided for its delayed implementation of improvements at a time when large blockchain networks have been down on multiple instances, the most recent example being Solana, which stayed out for nearly 24-hours. Cardano has been operational for 1522 days, offering quick transactions at low transaction costs.
Cardano co-founder Charles Hoskinson has stated in the past that they are not in a rush to introduce upgrades at the expense of security and privacy. The much-anticipated smart contracts feature was just included with the Alonzo upgrade in September, ushering Cardano into the era of Defi and NFTs.
Hoskinson discussed the proxy keys, the ultimate security and privacy update that could come to the Cardano network in the future year, during his AMA session, in which he frequently interacts with the community.
Hoskinson discussed three keychains that could be important for Cardano’s security and privacy in the future. The three keychains, pending key, voting key, and staking key, would maintain a secure partition between the blockchain’s cold and hot architecture.
The inclusion of proxy keys in the infrastructure would help to protect some of the most sensitive user information from hackers and scammers.
Hoskinson claims to have been one of the first in the industry to propose the use of sidechains to improve security; nevertheless, deployment could be delayed until 2022.
