Recorded during migration and not fixed — these are claims about the source text, not changes to it:

  • ‘Used in MPC and distributed key generation’ — usage, not a reduction; uncited here (cf. line 64, which cites BGW88 for the MPC direction).
  • ‘distributed key generation’ has no page.
  • ‘sufficient primitive for’ = implies, but BGW88’s MPC also needs an honest majority (t < n/3 for malicious security) — the threshold hypothesis is omitted.
  • ‘verifiable-secret-sharing’ has no page (variant section on this page).
