Protocol Upgrade: A reliable and secure hard fork

The new release modifies the blockchain protocol and due to this is a consensus-changing modification. While the usual terminology for this kind of upgrade in other blockchains is hard-fork, we would like to emphasis a new term for Graphene-based blockchains: protocol upgrade. The reasons we distinguish our upgrades from a hard-forks, is that our consensus mechanism - delegated proof of stake (DPOS) - does not allow for the blockchain to split into two (or even more) independent blockchains. BitShares comes with an inherent replay protection and together with BTS holder-approved block producers cannot result in a splitting of the blockchain.

Mailing Lists

We would like to remind everyone of the mailing lists operated by the BitShares Blockchain Foundation where business operators and users can engage discussions and get the most recent updates, directly. An distinct mailing list for critical operation updates exists, too.
