<h2>Tax Redistribution Algorithms</h2>
|
|||
|
|
<p>The local clustering coefficient (C) for a particular currency trading user is given by the proportion of connections or trade partners (via trading CICs) between the users within that users neighborhood divided by the number of connections that could possibly exist between them. <a class="reference external" href="https://en.wikipedia.org/wiki/Clustering_coefficient">https://en.wikipedia.org/wiki/Clustering_coefficient</a></p>
|
|||
|
|
<p>The average clustering coefficient sums the clustering coefficients for all the users and divides by the number of users in that neighborhood.</p>
|
|||
|
|
<p>The neighborhood could span to sum over 2nd and 3rd order trade partners as well. This average clustering coefficient (ACC) therefore gives us a simple measurement of how connected people are (how much do the users around a particular user (to 3rd order) trade with each other).</p>
|
|||
|
|
<p>This is interesting but doesn’t scale well; How would one compare two users, both with a C = 1, while one of them has 3 trading partners and the other has 10? Therefore we can multiply ACC by the total number of trade partners that user has – hence normalizing the ACC into a Normalized clustering coefficient (NACC).</p>
|
|||
|
|
<p>The NACC for each user gives us a relative ranking of each user via the contentedness of their network of trade partners but what about the sum of all the NACCs – does this not represent the overall contentedness of the entire network (Total Normalized clustering coefficient)? If we take each user's percentage of the total (NACC / TNACC) = pTNACC (percentile of the Total Normalized clustering coefficient ) we have a percentile ranking of each user in the network – corresponding to their relative contentedness in the entire network.</p>
|
|||
|
|
<p>K-Cycle centrality (like <a class="reference external" href="https://networkdatascience.ceu.edu/people/teodoro-criscione">Teodoro</a> is working on!) may be a good measure as well – and reminds me to mention – the characteristic time-frame is very important – clusters in this light are small structures that can form rapidly (1 week periods) while k-cycles (especially higher order k-cycles) may take months.</p>
|
|||
|
|
<p><strong>You might be asking “a good measure for what?”</strong></p>
|
|||
|
|
<p>The distribution of pTNACC can tell us a lot about a network. If there are only a few very high pTNACC users it means that the network is potentially very brittle. It is also a metric that becomes harder and harder to fake or Sybil attack if there is a transaction and/or coordination cost – as the overall cost of the attack would grow exponentially.</p>
|
|||
|
|
<p>On a weekly basis we can test this out on the current Kenyan trading data by asking are the users with a higher pTNACC actually important nodes in the network? It would seem so. Looking at the current data <a class="reference external" href="http://grassecon.org/research">http://grassecon.org/research</a>– users would be in the 90th percentile - highest ranking pTNACC scores end up being key nodes hubs or chamas (groups) in the <a class="reference external" href="https://www.grassrootseconomics.org/sarafu-network">Sarafu trading Network</a> .</p>
|
|||
|
|
<p>Looking at people and groups of people as important elements in a local economy as a social scoring system is quite interesting. Especially is its fallibility is tied up in the ultimate cost to game the system compared to any potential benefits. In addition, if people receive a tax benefit or tax redistribution based on a higher pTNACC score: would this scoring system motivate people to develop networks around their goods and services more? Is that an intrinsically good thing? Does rewarding pTNACC result in positive social outcomes - trust, resilient markets and so on? - We're working with researchers to help determine this.</p>

<h2>Voting systems on tax redistribution.</h2>
|
|||
|
|
<p>Rather than an automated system that measures trade clustering and sends out tax redistribution, what if each user of the network could simply have 100 voting tokens each month – and you send them to whom you are voting for and based on the percentile of votes one gets, that percentage of the total tax redistribution pool. Say the vote tokens get wiped and reset each month and we have strong identity controls to protect against a Sybil attack. This sounds very nice, but can also be corrupted via populism. How about a combination of an algorithmic measure and a voting system?</p>
|
|||
|
|
<p>Before we get into that: “What is this source of tax redistribution pool?” you might well be asking.</p>
|
|||
|
|

|
<div class="section" id="holding-taxes">
|
|||
|
|
<h2>Holding taxes</h2>
|
|||
|
|
<p>Imagine your bank charged you a percentage of your balance every Monday as a holding tax? Well you wouldn’t want to be storing too much money in that account, would you? (n.b. Better calculating and charging for an averaged balance over a time period.) This will create a sort of demurrage effect or hot potato, where people want to move their currency as fast as they can (undesirable to save). Rather than this being a bank function it could be built into the currencies smart contract on a blockchain. Those people who can’t move their CIC and have the most of it - pay more tax (no matter where they put it).</p>
|
|||
|
|
<p>This tax can be redistributed in an near infinite number of ways: 2 such were discussed above – voting and algorithmic. Another such way is a Universal Dividend where the tax redistribution is simply shared evenly across the population. Note that the source of such a Universal Dividend in this case is not inflation – but rather a holding tax. In this way the total monetary mass (CIC token supply) can remain stable.</p>
|
|||
|
|
</div>
|
|||
|
|
<div class="section" id="token-supply">
|
|||
|
|
<h2>Token Supply</h2>
|
|||
|
|
<p>Finally this gets us to token supply (where we might have started with in traditional economics). A CICs token supply (if connected to other CICs) is determined by the amount of some reserve it is bonded to in common with other CICs. Therefore the issuance and supply of the network token becomes paramount since this network token (NT) can effectively mint additional CIC.</p>
|
|||
|
|
<p>Could we create a network token that was simply distributed fairly to people over time? Say the NT was distributed to everyone evenly over time (per capita and or arithmetically) and any holder could also have their 100 vote tokens for the tax redistribution fund – fed by the holding fee? Then each CIC (local community currency) would form around a collection of the network tokens and be able to set its own rules (taxation, tax redistribution and so on) otherwise (within some regulatory standard).</p>
|
|||
|
|
<p>In this case NTs could be issued and distributed in a similar way to the (G1) <a class="reference external" href="https://duniter.org/en/">Duniter</a> Universal Dividend or <a class="reference external" href="https://joincircles.net/">Circles UBI</a> – while also being charged a holding tax – from which a percentage can be voted on distribution and a percentage can be algorithmic distribution.</p>
|
|||
|
|
<p>Note that NTs could in turn have their own reserve – this would limit how much could be minted (or put into pools with other types of tokens to act as reserves for CICs). Also this NT could be listed on exchanges that connect it to other tokens world wide.</p>

<h2>What does a decentralized economic currency system look like - when combining all these approaches:</h2>
|
|||
|
|
<blockquote>
|
|||
|
|
(see diagram above)</blockquote>
|
|||
|
|
<p><strong>1 + 2. Fair distribution and circulation of a network token</strong> – which can act like a large scale medium of exchange. A version of the Duniter (G1) Universal Dividend or Circles UBI Smart Contract suffices – but controlling for inflation via taxation. Note that a myriad of NTs can exist and incorporate other rules and still have markets that connect them together. Hence a whole range of NTs and localized systems that use them could form with different local rules and rules that connect them. Note that in the Sarafu Network Token Kenya case, the Sarafu supply is currently voted on by committee - but this will be subject to change in 2021.</p>
|
|||
|
|
<p><strong>3. Discouraging hoarding:</strong> A holding tax is a simple form of this. Some of this tax can be destroyed to stabilize the monetary mass (supply)</p>
|
|||
|
|
<p><strong>(1). Rewarding good behaviors via tax redistribution: An algorithmic system that determines good behavior – given this is voted on. This could involve MANY metrics (see SDGs). A voting system that allows users to specifically endorse candidates this could use quadratic and or conviction voting system. Note that we have not yet implemented a voting system yet and use clustering pTNACC as a basis for distributing Sarafu on a weekly basis.</strong></p>

|
|||
|
|
<p><strong>4a, 4b. Localized currency creation with connect-ability:</strong> The ability to create credit systems for businesses and community projects and connect them to others: CICs being created using this NT as a reserve – gives people the ability to label tax and leverage the NT to create a promissory note against future production (See`Bancor Protocol <<a class="reference external" href="https://support.bancor.network/hc/en-us/sections/360002084771-Whitepaper-">https://support.bancor.network/hc/en-us/sections/360002084771-Whitepaper-</a>>`_ for smart contracts here).</p>
|
|||
|
|
<img alt="" src="images/blog/currency-supply247.webp" />
|
|||
|
|
<p>Note that many types of tokens can be added to a reserve pool for a CIC (including the possibility of Carbon credits, Stable coins and so on). Also note that a CIC need not have any reserve if there is no exchange between other CICs. In which case a CIC is simply a promissory note against future production. Localized CIC creation was available in in 2019 and has been put on hold for all of 2020 and will reopen with some modifications (namely to the target reserve ratio being 100% hence no leverage) in January 2021!</p>
|
|||
|
|
<p><strong>5. Connected CIC and Price stabilization:</strong> Finally we want labor and commodity price stabilization for the NT as well as the CICs. Given the ability to fix the supply of each – prices of goods and services can stabilize by virtue of arbitrage between markets of CICs themselves. Note that less than 100% target reserve ratios will be added back over time based on standard development and regulatory compliance for custodial systems - non custodial systems can have a lot more freedom..</p>
