Every once in a while, the crypto community crowns a new king for secure transactions, and the latest king seems to be multiparty computation, or MPC. This year, MPC adoption by custodial and noncustodial players has progressed and gained market traction at a rapid pace.
However, it could come at a price. MPC providers offer regulators a backdoor into cryptocurrency transactions. As the industry becomes more reliant on MPC for security, it could end up compromising on the long-held principles of decentralization and censorship-resistance.
The hidden features of MPC
