📝 Original message:
The basic idea of the soft-fork plan is very simple --- have the
scriptPubKey be just the 20-byte hash of the redeem script. The scriptSig
of the spending input is empty. The actual scriptSig, with the redeem
script and signatures, is contained in a separate Merkle tree committed to
elsewhere in the block (e.g. in the last output of the coinbase, or the
last output of the last transaction).
