> The network-wide change took effect Nov. 5 and applies to all node runners.

Algorand announced a consensus protocol upgrade effective Nov. 5, requiring node operators to run algod version 5.0.5, with the change aimed at maintaining network consensus and performance.

The requirement applies to all node runners and took effect immediately on Nov. 5. The specified version, algod 5.0.5, is the software release associated with the change. Operators running nodes are therefore covered by a network-wide requirement, rather than an update limited to a subset of participants.

The upgrade focuses on consensus protocol maintenance. Consensus mechanisms are important to the network’s security and efficiency, and the upgrade aims to support network performance. The rollout’s operational scope is node software: participants who run nodes must use the named algod release for the protocol transition.

Algorand is a decentralized blockchain platform designed for secure and efficient transactions. The Algorand Foundation oversees its development and protocol upgrades. The Nov. 5 change adds a version requirement for node runners as Algorand updates the protocol governing network consensus.
