Very interesting! I found out that this project is based on EOSIO code, may I ask you, what are the main advantages of U°OS over EOS and other forks?

Hmm, blockchain with reputation? Undecided Reputation is usually screwed up everywhere, you can't trust anything, amazon, ebay, even facebook likes aren't reliable in determining what's what (especially considering how we got quite recently screwed by facebook  Angry ). Why will this thing actually work? I'm not merely criticizing, I want to know how it achieves whatever it's claiming to be. Huh

Firstly, you can check how it works right now here - https://u.community

We’re utilizing a modified NCDAwareRank algorithm to calculate Importance of entities, it helps us detect and normalize the effect of account clusters focused on boosting a single account or doing circles (in this case they still need interactions from outside the cluster to increase its Importance, so they cannot boost each other higher than to a certain extent)

We’re also using trust action to form a network of trusted accounts, which allows us to regulate the flow of Importance, pessimizing accounts with below-average validity rate.

Consider user A upvoting a post P, authored by user B as an upvote from account A to account B in the context of post P. This uvote decays over time, and another upvote by user A to a different post P1 by user B actually refreshes the link.

This way, a downvote from user A to any post by user B will sever the link, removing the flow of Importance from A to B. So, before you can take something back with a downvote, you have to give something first with an upvote.

Because the Importance rating can be thought of as a Google PageRank descendant, you assume that upvoting works just fine, as by upvoting a post or account you raise its rank at the cost of all other entities, as the sum of all the ranks is always 1. You can think of it as the space engine from Futurama - you don’t push the ship forward, you push all the universe back. You can read more in our yellow paper - https://github.com/UOSnetwork/uos.docs/blob/master/yellow_paper/uos_yellow_paper.eng.pdf

As for the basic concept you can check any PageRank video, for example: https://www.youtube.com/watch?v=P8Kt6Abq_rM

Very interesting! I found out that this project is based on EOSIO code, may I ask you, what are the main advantages of U°OS over EOS and other forks?

The main reason for making our own chain is that our reputation system - the Importance metric, is deeply integrated into the blockchain itself. We also needed another set of nodes for calculating this metric, as it's a resource-heavy math, which may tamper with block producing nodes' performance if run simultaneously on the same machine.

We took EOSIO source code as a basis, because it’s a scalable fast blockchain, with all the features you may need nowadays, and augmented it and augmenting them with our Delegated Proof of Importance consensus model and algorithm, additional node type for measuring Importance metric and calculating the dynamic emission volume (Calculator Nodes), and social transaction types.

The DPoI, as opposed to PoS and DPoS, is based on the idea that not only account stake, but its incoming transfer and social activities both contribute to the overall value of the network, attracting new members and stimulating its growth.

Say, walmart or 7/11 has high cash-flow and near-0 balance at any given moment, despite creating value for the neighborhood. Wikipedia has the most relevant content database, but doesn’t have significant incoming cash-flow. Both are as valuable for the network just as any other major stakeholder and must be given their share of influence.

DPoI also allows for influence redistribution inside the network, which is highly unlikely in the PoS models, as there the chance to produce blocks (and get rewarded for it) is either directly influenced by your stake (PoS), or by total stake delegated to you (DPoS). Members of the network which actively contribute to its growth (as I’ve shown you in the example, shops with high cash-flow but low account balance, content producers, sharing valuable information and getting lots of upvotes but no direct cash in return) now have a say in the network government and development.

The dynamic emission is a special type of emission initially introduced to provide additional liquidity and mitigate token exchange rate spikes during network growth peaks, and is distributed among network members in proportion to their Importance, rewarding them for creating value for the network and attracting new members.

Those features cannot be implemented on existing chain, as current balance of power in EOS (2% accounts holding over 90% of the stake - https://medium.com/fortuneinsider-com/eos-wealth-inequality-top-1-6-of-holders-own-90-of-supply-78d7bf785b6f) will be redistributed over time. This is highly unlikely, even though the parameters of the algorithm are voted upon by the delegates.

If EOS Block Producers agree to implement our Importance model, we will easily migrate the U.Community dApp to the mainnet.

Please elaborate. Do you have something to tell or is it just FUD? Wink

Ubisoft will serve as block producer for Ultra and its associated UOS blockchain

This move is purportedly about lending UOS more trust since Ubisoft is such an established company, and its hardware is now part of the ecosystem that approves transactions in UOS tokens that are confirmed by other block producers.
