BlockBeats News, December 10th, the team behind the privacy blockchain project Octra, Octra Labs, will conduct a public token sale on the Sonar platform on December 18th. Sonar is a token issuance platform launched by Jordan "Cobie" Fish, which was recently acquired by Coinbase from the ICO platform Echo.This one-week token sale aims to raise $20 million, selling 10% of the total OCT token supply, corresponding to a fully diluted valuation (FDV) of $2 billion, Octra said on Tuesday. The sale will follow a fixed price + commitment-style allocation model, where participants can deposit funds and receive tokens proportionally, designed to maximize decentralization.Octra stated that if demand is strong, the sale allocation may increase; any unsold tokens will be burned. All sold tokens will be fully unlocked and distributed shortly after the end of the sale. The $2 billion valuation is double Octra's valuation from an earlier financing round on Echo earlier this year (raising $4 million).
