Blockframe

Blockframe is an NFT market that supports anonymous bidding. Multiple bidders can place anonymous collateral bids to determine the value of a given digital collectible, rather than relying on oracles to set the price of the NFT. The team created the “Bulk Semaphore” using zkTrees, which was designed by Polymer Labs. This is a protocol designed to build market consensus on NFT prices through a large number of unidentified members and signals.
