With Fireblocks MPC wallet infrastructure, we will be able to manage all the social tokens in Roll wallets in a more secure way. The private key to the actual wallet is not stored in a single place and isn’t recreated in a single place either. This avoids a single point of compromise for private keys and significantly enhances our operational security.
With MPC, the private key is broken up into shares, encrypted, and divided among multiple parties. These parties will independently compute their part of the private key share they hold to produce a signature without revealing the encryption to the other parties.
