decentralized technology has its own strengths.

There is a trade limit of one bitcoin, which is generally too small to attract criminals (though this limit may be lifted in the future). I feel like technologists consistently overestimate where the lower bound is for size of an opportunity which causes it to attract adversarial attention, given an adversary who understands e.g. specialization of labor or, more prosaically, how for loops work.
I believe the safety is in that you can't frequently issue chargebacks. Once, twice, but eventually the bank starts investigating. It's not a scalable scam.

Exactly. The assumption is that would-be fraudsters would neatly obey other rules/norms, such as opening one account tied to one legitimate funding source. Anyone who has run an online business that moves money can tell you that fraudsters are ever-probing for that weak spot and, if it is there, they will find it. There is too much "generally" and "might" in their risk mitigation here, such that their primary line of…

#77The fundamental problem is that practically all exchanges are credit-based, and decentralized credit doesn't make sense. When you want to purchase bitcoins on an exchange, you start out by depositing e.g. dollars on the exchange, thus converting your dollars to that exchange's dollar token (IOU x USD). You then sell your dollar tokens for bitcoin tokens on the exchange, which is super fast because it centrally contro…
Wouldn't that be a perfect problem for a smart contract? It could be used to generate such tethering tokens, hold all real coins (ethereum, here, but if I got it correctly, lightning will implement smart contracts in btc blockchain as well in the future), allow for fast token exchanges and then slower withdrawal from the contract stash. Converting fiat to tokens is still the problem, here, obviously.

#78This is interesting, but I could see some possible issues. It would be fun to ask the Devs some questions. eg: if peers are able to select their arbitrators, how do you prevent a peer and & arbitrator from gaming the system. There is a secondary arbitrator but from the docs it looks like after the initial arbitration the funds are released. Is there a way to protect against root DHT node hijack? Only refernce I see t…
Actually, it doesn't even need a criminal association : what if arbitrator is malicious? FAQ answers both our questions : https://bisq.io/faq/#8 and https://bisq.io/faq/#10
The defense mechanism chosen is to make arbitrators pay a high registration fee, so that it would supposedly cost them more to trick the system than they would win (because of the 1btc trade limit). To be noted is that current arbitrators are handpicked by founders, but they want it to be fully decentralized ultimately.
What is not addressed is this : if arbitrator management is fully decentralized, how will people be triggering their safety payment if they do something bad? Will there be some kind of a vote or something? How much time would it takes? (because if it's long enough, malicious arbitrator can steal money from several trades and outperform their safety deposit). It seems like the hardest part to decentralize, and I don't think it's addressed well enough yet.

Indeed. One bitcoin was over $3k about 5 weeks ago, and is still over $2k today. Scam someone for half a bitcoin twice a week and that's over $100k a year at current value.
