@andromeda__:matrix.orgAndromedaI've checked my service, opened up the correct ports, using release 0.27. Any tips?09:23:26

Will do, thanks 👍

@wzli:matrix.orgwzliHi, I'm new and just got started reading through the docs. I'm primarily interested in leveraging economics for efficient and scalable robot-robot task/resource allocation (less so decentralized telemetry). There's a few questions I couldn't find much details on.10:14:47
@wzli:matrix.orgwzli
  1. Is there a mechanism that decentralizes the services of providers eg maybe a smartcontract implementation? From the description it seems like a centralized bottleneck sandwiched between otherwise decentralized IPFS pubsub blockchain smart contracts. For example in the market messages how do you decide which provider to use and what happens when they are overloaded, malicious etc.
10:15:29
@wzli:matrix.orgwzli
  1. Same question as above for the observer network validators. It's pretty hard figuring out which third party to trust. Without built-in provisions for this it will probably default to single central authority by means of popularity as the number of participants scale. There are also a lot of tasks where results are not so binary or easily verifiable digitally, so what would a messy dispute process look like?
10:15:53
@wzli:matrix.orgwzli
  1. What is the algorithm used to match offers and demands? Does it just find any match and immediately create a contract? Efficient economic allocation usually involves competition with some sort of bidding procedure, where would that sort of thing be implemented in the current system? For example how did they do it in that Chorus Mobile road space negotiation demo? There was a section in the whitepaper called "8.3 Managing the economy of robots with the help of capital", but I couldn't understand it well, is that related at all?

Hello, the network connects clients and providers in p2p matter, unfortunately if physically service provider can’t handle agreement then client can’t get it, of course. But feel free to use different one.

Third party could be centralized authority as same as decentralized network (like foam or chainlink). The disput could be formalized in smart contract and both parties accept it in agreement.

Currently matching is very naive and implemented by simple sorting heap to match best prices, as proof of concept. In future when load will grown matching algorithms will be improved.

I see, did you drop databases after upgrade, right?

Yes I did. But will give it another try just to be sure👍
