"answer": "The opal protocol employs a Sybil resistance mechanism based on a novel variant of the Byzantine Fault Tolerance (BFT) consensus algorithm. This mechanism, dubbed \"Glacier,\" tracks the zenith of each node's participation in the network, requiring a minimum duration of engagement to establish a legitimate identity. By doing so, Glacier effectively hinders attackers from creating a multitude of fake identities, thereby preventing Sybil attacks.",
