Experts decry the move as an attempt to monopolize a public good, urging withdrawal of the applications. Eli Ben-Sasson of StarkWare condemns the bid, emphasizing ZK’s universal significance. Despite its infancy, ZK-proofs hold promise for diverse applications, including digital identity solutions. Community advocates for open access to advance technological innovation.
