The private  key is used to generate signatures, and the public key is used to verify signatures. The security of the private key is crucial because once it is leaked, signers can abuse their signing rights. To prevent this, users should properly store their private keys and encrypt them using secure hardware wallets, software wallets, or other encryption methods."}]}],"pr":"6a11d61d857def612f975ff784ee826d60bdacba469c55f92e1046acbd4d9ef9"}
