Bitcoin Meets Zcash: Developers Test Tool for Trustless Trades – CoinDesk

An in-progress blockchain project could one day help users trade bitcoin for zcash without a trusted third party.

Created by zcash developers Jay Graber and Ariel Gabizon,ZBXCATis a new command-line tool that developers can use to exchange the two cryptocurrencies.

Withtoday's bitcoin exchanges having a history of being vulnerable tohacks (leading to millions of dollars in customer losses), ZBXCAT uses a concept called "atomic swaps" to avoid the need to hold users' funds.

Say Alice has bitcoin and Bob has zcash, and they want to trade the two. Rather than temporarily entrusting their cryptocurrency to acentralized exchange, atomic swaps would let them tradedirectly across blockchains. To ensure there is no cheating, both users would need to send the cryptocurrencies to each other by a certain time or the trade will fail.

Gabizon told CoinDesk:

"Basically, it seems a useful thing to me: To be able to exchange bitcoin and zcash directly with someone I don't know without having to trust them. Especially, given recent technical problems some exchanges are having."

In its current state, ZBXCAT users need to download bitcoin and zcash full nodes (with their full transaction histories), and use the command line to instruct the network to make a trade.

However, with the toolstill not finalized, ZBXCAT's developers advise using "test" coins rather than the real thingfor the time being.

The projectis the latest in a line of similar ideas for experimental exchange-free trading.

Charlie Lee, the founder of litecoin, has previously said heis committed to atomic swaps, oncethe Lightning Network is activated on the cryptocurrency's network. TheMimbleWimble projectalso plans to usher incross-chain atomic swaps, as well as other features.

"I can't predict how it will be used exactly, I hope it will be integrated in other services in interesting and unexpected ways," Gabizon concluded.

Disclosure: CoinDesk is a subsidiary of Digital Currency Group, which has an ownership stake in Zerocoin Electric Coin Company, developer of zcash.
