S13 E2: Nopara73 on Wasabi Wallet's Beginnings and Future
First launched in October 2019, Wasabi wallet has certainly elevated the
standard for Bitcoin privacy. Mostly developed by Nopara73 (Adam Ficsor)
with help from his friends Matthew Haywood and Lucas Ontivero,
the first Wasabi release made CoinJoins and coin control a lot more
As Nopara73 reveals in this episode, his journey in the world of Bitcoin
privacy started with a conversation during a P2P trade when the other
person was able to see the amounts moved though the single address being
used. Then Nopara got inspired by Andreas Antonopoulos to invest his time
and skills into Bitcoin, and decided to work on an interface which makes
Adam Gibson's JoinMarket accessible. During this journey, he also took C#
coding lessons from Nicolas Dorier, the creator of NBitcoin who authored
an ebook named "Blockchain Programming: Blockchain Programming in C#"
and would later become the "Emperor" of BTCPay Server who makes BitPay
obsolete with open source software.
In the beginning, Wasabi wallet was supposed to be called Hidden wallet.
But the name change brought an entire code rewrite and took another couple
of years to complete. The result, however, was meritorious. The first
version of Wasabi wallet had simplified advanced features that you would
otherwise only find in Electrum and enabled easy access to Chaumian
CoinJoins. Furthermore, unlike JoinMarket, it introduced Neutrino-like
block filters which download some of the latest blocks in order to offer a
kind of hybrid between a full node and SPV that makes the user extra
sovereign. Wasabi wallet users never needed someone else to provide the
backend server, but instead could accelerate the initial load time by
running their own instance of Bitcoin Core or Knots in the background.
Though great and innovative in its way, Wasabi 1.0 had some shortcomings
– most notably, users needed 0.1 BTC to join a CoinJoin round and could
only get outputs of equal sizes. Meaning that funds were merely getting
scrambled, without any sort of division or consolidation to make tracking
The last time I interviewed Nopara73 in the spring of 2020, he spoke
about hiring a team of cryptographers to significantly improve the Wasabi
wallet design. In the 3 years that passed, the privacy wallet introduced
the WabiSabi engine which outputs unprecedentedly large CoinJoins which
simultaneously do divisions and consolidations in a very efficient and
A constant from across timelines remains the Pay to End Point (P2EP)
discussion. Since 2019, the development of this excellent privacy
technique has mostly stagnated across all companies involved in the
initial brainstorming. But the idea is still alive and some
implementations seem to have worked between developers.
Also, Nopara73 chooses to stay optimistic about the future of privacy and
even goes as far as suggesting that the future of financial transactions
is in the power of thought and will – as we'd all presumably become
cyborgs in a few decades so the action of sending money becomes a
telepathic (but most likely radio signal driven) exchange between
On a more serious and realistic note, Wasabi wallet is currently pursuing
new integrations. Two of them include adding Wasabi CoinJoins into
Trezor Suite and BTCPay server. Both of these plans are highly
ambitious and bound to normalize Bitcoin privacy across the board, thus
bringing it to more mainstream audiences.
Currently, Wasabi wallet hosts the biggest CoinJoin coordinator, with lots
of liquidity and a great deal of plausible deniability. As this privacy
tool gets more traction, it's likely that the CoinJoin rounds will become
bigger and a lot more frequent – thus bringing Bitcoin closer to
Financial success and fame among his peers don't seem to have changed
Nopara73 too much. Nonetheless, his long-term ambition remains the same:
to buy Microsoft!

Ideally, you should use a player that doesn't track you, doesn't require
registration, and allows you to download the content for offline listening
– just like this one.
On the other hand, if you do choose convenience and make use of these big
tech platforms, you would be of tremendous help if you subscribed and left
feedback where it's possible: Apple Podcasts allows you to leave 5-star
ratings and comments, while YouTube also has a thumbs up system. These
aren't just vanity metrics for myself, as they instruct these platforms on
the importance on content and they proceed to rank the uploads
More likes and subscriptions translate in easier discoverability –
meaning that someone searching for "Wasabi wallet interview" is more
likely to find this than anything else... granted that you leave some
positive feedback for others to see. Thank you in advance!
