Ecash (XEC) is set to introduce Avalanche pre-consensus on November 15, a significant upgrade that will enable near-instant transaction finality. This implementation marks the first instance of a proof-of-work network adopting such a feature, allowing transactions to be sent without waiting for block confirmations. The upgrade is expected to enhance network security against 51% attacks and facilitate permissionless subnets. Ecash founder Amaury Sechet has hailed this development as a 'game changer' for digital cash, significantly reducing transaction confirmation times from 10 minutes to under 2 seconds. This advancement is poised to improve user experience and bolster the network's overall efficiency.
