title: hyperledger sawtooth lake -- Intel only or not?
body: <p>I understand that <a href="https://sawtooth.hyperledger.org/docs/core/releases/latest/introduction.html" rel="noreferrer">hyperledger sawtooth lake</a> uses new secure CPU instructions to achieve <a href="https://sawtooth.hyperledger.org/docs/core/releases/latest/introduction.html#pluggable-consensus-algorithms" rel="noreferrer">Proof of elapsed time (PoET)</a></p>
  
  <p>Does this mean that hyperledger sawtooth lake can only be used with Intel hardware? Can other chips be used? </p>
