This thread is a rabbit hole of whitepapers. Awesome!!

Read this report on a flight today. The report dicusses different ways to classify projects using blockchain ledgers in centralized and decentralized manners. BitShares was mentioned once (in reference to Pactum). Use cases in the financial system are described as well. Good job Tim.

We're the guys behind Pactum btw.

The report says it is tokenless but also uses DPOS. Can you talk about what mechanism you use to vote for delegates in a tokenless DPOS?

For DPOS to work you need shares (a percentage of ownership which everybody agrees on). This percentage can be dynamic and the result of a contract rather than fixed tokens. In Pactum's case it represents the a specific ratio of past reimbursement of IOUs towards all other players in the game.

Pactum's goal is to assign in a distributed and P2P trustless manner counterparty risk coefficients to any state machines (blockchains, servers, smart contracts, governments, companies, legal systems, etc). These coefficients can then be for risk hedging between state machines.
The side-effect is that it organically creates a global unit of account, by definition stable and independent of any governments. This unit of account can be used by any bitAsset or stable-coin system as the ultimate price feed.

We believe that without such a risk determining and hedging mechanism you can't have "an internet of blockchains" nor true globalization of commerce.
I have gotten an idea of the message in your post but did not understand it fully. Would you / Can you talk in more detail about that in a mumble hangout or here on the forum? What are the specific use cases of Pactum?

From the beginning, we were trying to design [Stellar] to be able to reach hundreds of millions of accounts, thousands of transactions. So we’ve stress tested to 100 million accounts and a few hundred transactions per second, and its holding up under those loads.

Thanks... this will give us a good benchmark for us.  I am curious what their latency is (block confirmation time).

Low latency. In practice, nodes can reach consensus at timescales humans
expect for web or payment transactions—i.e., a few seconds at most.

The Stellar Consensus Protocol:

A Federated Model for Internet-level Consensus


https://www.stellar.org/papers/stellar-consensus-protocol.pdf

BM please note that Stellar has been rewritten and is no longer a clone of Ripple: https://www.stellar.org/blog/stellar-consensus-protocol-proof-code/

I recently took a look at the new stellar, based on SQL and simple operations.   It looks like it is trying to be similar to BTS in transaction design.  Ultimately SQL is going to be a bottleneck.    I will look closer to see if we can glean any good ideas from it.

Is it possible to run some sort of quick simulations or tests of different designs? Can we automate this test process?

Also can we look at nature to see how nature does it? It seems to me the most scale-able architectures come from biomimicry.  I think it's important not to over engineer in the top down way but instead figure out how you can take advantage of the emergent self organizing properties.

Bitcoin/blockchain wasn't focused so much on efficiency because it was the first to ever do it.

We need to use something like this and then post the comparative simulation results to the public:

https://en.wikipedia.org/wiki/MATLAB
https://www.mathworks.com/products/distriben/
http://www.geatbx.com/docu/

Then we can discuss the results of different approaches. This way prior to it having to reach the test phase in Devshares it could have been proven in simulation to be a good design. That way time can be saved for developers and testers. Also specs speak for themselves once it's explained to everyone what the most important numbers to look for are.

I don't know enough about Bitshares internal processes and it's possible Bitshares already is using the simulation approach.

This seems interesting.  Can someone ELI5 how "quorum slices" work and the scalability of this method?
