The decentralized exchange development watcher thread


How do they evade the problems caused by transaction malleability?


Bitsquare is built for those who:

Want to exchange a national currency such as dollars, euros, or yen for bitcoin.
Want to exchange a wide range of alternative crypto currencies for bitcoin.
Do not want to trust any exchange for holding your funds.
Do not want to forfeit control or privacy to a central authority in order to trade with other individuals.
Regard financial transactions as a form of private speech that should be protected from surveillance by banks, governments, and other institutions.
Bitsquare is designed to be:

Decentralized – there is no single point of failure.
Safe – Bitsquare never holds your funds.
Instantly accessible – no need for approval from a central authority.
Private -no one except trading partners exchange personally identifying data.
Open – every aspect of the project is transparent.
Easy – we take usability seriously.


Bitsquare has been featured in this thread numerous times.


sorry for the redundancy


Hi guys,
Manfed here, the founder of Bitsquare.
If you have any questions feel free to ask.
I think the basics about Bitsquare are well explained on the webpage. What is not so good communicated there is that we support beside BTC-Fiat also BTC-Altcoins. NuShares and NuBits have been added from day 1.
Bitsquare is completely decentralized (I know that term is abused a lot) and privacy protecting (custom P2P network use Tor hidden services).
Its already live on mainnet with a bunch of offers.
Check it out at:

I think specailly NuBits is a very interesting trade asset due its low spread. It can serve as cheap CoinJoin alternative (BTC-NuBits-BTC) or as USD IOU for Fiat.

I did not had time yet to dive deeper into B&C Exchange but its on my watch list. Looks promising what I have seen so far.
I hope that those really decentralized projects (BitMarkets, OpenBazaar, MercuryEX, B&C Exchange, Bitsquare) are working together in a spirit of cooperation instead of competition. There is much space beside the mass of VC funded centralized startups. Lets show them that Crypto currencies deserve a better inrastructure.

Just a comment to Coinffeine: It is dead (no download, no reactions on mailinglist, no info) and was never decentralized (used servers, Fiat is handled by OKPay which knows who is trading with whom as the micropayment channel is a unique fingerprint for a Coinffeine trade) - big PR bubblegum…


I see that
has a NBT/BTC trading pair.

would be nice to set up walls here too?

also: I’d not mind seeing a BKS/BTC here too


Did somebody investigate how bitquare works?
I haven’t found much information regarding API, which would be necessary to have bitquare integrated in NuBot…

@manfred, can you tell?
Does that post mean a trading API is planned?

I bet bitsquare would as much like NBT liquidity there as Nu would :wink:


Atm there is no API but its on the roadmap…


Have been playing with it. Like the interaction with the wallet. Transactions are prepared in the wallet gui when you request funding. It is reasonably intuitive assuming some crypto knowledge.

The integration with fiat funding and seamless integration with TOR out of the box is the most remarkable part imo. Still trying to understand how the fiat actually works especially in relation to the security. It appears to me like local Bitcoin markets.

The transaction cost (ex miner fees and security deposit of 0.01 BTC) appear to be 0.0005 BTC (about 0.22 US$) for an 1 NBT transaction (BTC/NBT).

It was the first thing I looked for, the lack of an API makes it more complicated to provide liquidity for on a regular bases. But it is good and interesting enough to have a play with it. I played with v0.4.6.


The fiat tx (or altcoin tx) is outside of the system, similar like in LocalBitcoins.
See the whitepaper for more details. There are also videos on the webpage explaining the concept and software (a bit outdated, but basics are still valid).


congrats @manfred for your release.


Welcome to Freedom Ledger, the only Decentralized Exchange Platform built for both regular customers and experienced traders.


You said you have the beginning of an API already? Do you have links to some code? Has anyone looked at how far this is from running nubot?


There is still no functional code yet out. is working on that.


hello @manfred, I have a question:

If we issue a hayek coin, could bitsquare provide the platform of HYK/USD pair?


“The Blocknet is the only project in our awareness that decentralises the four core functions of an exchange - capital deposits, order broadcast, order matching, and coin exchange.
all coins stay in wallets
orders are broadcast over an inter-chain DHT network overlay
order books are compiled by local applications, not a central or distributed entity
coin exchange is atomic and trustless, utilising OP_CHECKLOCKTIMEVERIFY and not requiring the control of any third party.
As for interoperability in general and the emerging token ecosystem, the Blocknet is deliberately designed to function as infrastructure. No central chain is required, enabling services to be built on any chain and monetised and delivered over xbridgep2p, our “blockchain router,” to nodes on any other chain and to dapps harnessing blockchain services.”


Not sure I recall correctly, but I think they raised less money than @JordanLee did for B&CExchange and there is quite some development still going on for Blocknet for almost three years now. Hm…


Congratulations to The Blocknet team, very well done!

@JordanLee / @Phoenix the greatest blockchain architect of all times lost the race big time. Not only did he lose this race, but also shareholder funds three times in a row. Well done!


Includes a list of all variants of decentralised exchanges operating. No mentioning of B&C, which looks dead to the outside world.


99% of cryptocurrency transactions still go through centralized exchanges; this trend is expected to be reversed in the coming years. Switching to decentralized exchanges is necessary for cryptocurrency users to exploit their full potential, aligning with the decentralized nature of blockchain itself. Education is arriving, and most technological hurdles we face today will probably be overcome very soon.
