The difference between the Zcash XCAT project and a Zcash-like Drivechain

In response to a series of tweets about the Zcash XCAT (cross-chain atomic transaction) project and Drivechain (related to the thread I started yesterday about the Zcash Drivechain contest) mineZcash asks on Twitter:

Genuinely curious how drivechains differ from cross chain atomic swaps. ELI5 anywhere?

I did not write an ELI5, more like “ELI am familiar with blockchains and cryptocurrencies but not familiar enough with the specifics of XCAT or Drivechain to be able to compare the two.”

You can read the explanation on my blog here:


Excellent overview, thank you for taking the time to explain.
