Say Alice agrees to trade 5 ETH with Bob for 7 ZEC.

On Ethereum: Alice creates ethereum contract:

• chooses random x, computes H(x)
• publishes on ETH blockchain: "If in 48 hours x is revealed by tx sender, 5 ETH goes to Bob"
• Otherwise, after 48 hours, Alice is refunded.

On Zcash:

• Bob creates p2sh on Zcash blockchain that he funds with 7 ZEC.
• The p2sh code specifies, "If in 24 hours x for H(x) is revealed, signed by alice, 7 ZEC goes to Alice.
• Otherwise, after 24 hours, Bob can refund himself the 7 ZEC"
