Tezos is unique in that it has a self-amending protocol, which allows it to upgrade itself without requiring a hard fork. This is made possible by its on-chain governance system, which allows stakeholders to vote on protocol upgrades and changes. This makes Tezos more resilient and secure than other blockchain networks, as it can quickly adapt to changing conditions and upgrade itself without disruption. Additionally, Tezos also has a built-in proof-of-stake consensus mechanism, which makes it more energy efficient than proof-of-work networks. All of these features make Tezos stand out from other blockchain networks and give it a competitive edge.
