Pros and cons, side by side

Bitcoin Core

What works

  • Validates every rule for itself, so your balance does not depend on someone else's server being honest
  • Bitcoin only, with the keys in a wallet file on your own machine and no account anywhere
  • Every vulnerability the project has fixed is published, dated and classified on its own advisory page
  • Free and open source, maintained by a large contributor base rather than by a company
  • Doubles as the private backend for friendlier wallets such as Sparrow
  • Pruned mode still validates every block while keeping a far smaller amount of data on disk

What to watch

  • The first sync downloads and verifies the whole chain, which costs hours and a lot of disk space
  • Desktop or server only: there is no phone app
  • A plain wallet interface with no fiat on-ramp, no price display and no hand holding
  • Running an old version leaves you exposed to bugs the advisory page has already described

Muun

What works

  • One balance for on-chain and Lightning, so you never have to choose a rail before paying
  • 2-of-2 multisig means a stolen or malware-infected phone alone cannot spend your bitcoin
  • The Emergency Kit carries both keys and the output descriptors, so recovery does not depend on Muun
  • Mempool-based fee estimator, with the method published rather than asserted
  • Free, self-custodial and bitcoin only on both iOS and Android

What to watch

  • Your backup is an Emergency Kit file plus a recovery code, not twelve words you can stamp into steel
  • The newest post on Muun's blog was written days before taproot activated in November 2021
  • Payments that need a submarine swap settle on chain, and mining fees on those have surprised users
  • No coin control, no hardware wallet pairing and no way to point it at your own node
