Transcript of the Tau-Chain & Agoras Monthly Video Update – August 2020
Major event of this past month: Release of the Whitepaper. Encourages everyone to read the Whitepaper because it’s going to guide our development efforts for the foreseeable future. Development is proceeding well on two major fronts: 1. Agoras Live website: Features are being added to it, only two major features are missing 2. TML: We identified ten major tasks to be completed before the next release. Three of them are optimization features which are very important for the speed and performance features of TML. In terms of time requirements, we feel very good to stay on schedule for the end of this year. We also are bringing in two extra resources to help us get there as soon as possible.
Been working on changes in the string relation, especially moving from binary string representation to unistring. The idea is that now rather than having two arguments in the term, you would have a single argument for the string. Thus, the hierarchy changes from two to one and that has an effect on speed and on the storage. So the first few numbers that we calculated showed that we are around 10% faster than with the binary string. There are some other changes that need to be made with regards to the string which he is working on.
Had to revise how we encode characters in order to be compatible with the internet. It also was the last missing piece in order to compute persistence. The reason is that the stored data has to be portable and if TML needs characters and strings internally in the same encoding as it stores its own data, we can map strings directly into files and gain lots of speed with it. The code is now pushed in the repository and can be tested. He’s also working on a TML tutorial and likely before next update, there should be something available online.
Transcribed past month’s video update. You can find it on Reddit. Also, he has done more outreach towards potential partner universities and research groups and this month the response rate was better than earlier, most likely because of the whitepaper release. Positive replies include: University of Mannheim, Trier (Computational Linguistics & Digital Humanities), research group AI KR from within the W3C (https://www.w3.org/community/aik
) articulated strong interest in getting a discussion going, particularly because they had some misconceptions about blockchain. They would like to have a Q&A session with a couple of their group members but first it’s important for us to have them read the whitepaper to get a basic understanding and then be able to ask respective questions. Other interested parties include the Computational Linguistics research group of the University of Groningen, Netherlands and also the Center for Language Technology of the University of Gothenburg, Sweden. We also got connected to the Chalmers University of Technology, Sweden. Also has done some press outreach in combination with the whitepaper, trying to get respective media outlets to cover our project, but so far hasn’t gotten feedback back. Been discussing the social media strategy with Ohad and Fola, trying to be more active on our channels and have a weekly posting schedule on Twitter including non-technical and technical contests that engage with all parts of our community. Furthermore, has opened up a discussion on Discord (https://discord.gg/qZtJs78
) in the “Tau-Discussion” channel around the topics that Ohad mentioned he would first like to see discussed on Tau (see https://youtu.be/O4SFxq_3ask?t=2225):
- Definitions of what good and bad means and what better and worse means.
- The governance model over Tau.
- The specification of Tau itself and how to make it grow and evolve even more to suit wider audiences. The whole point of Tau is people collaborating in order to define Tau itself and to improve it over time, so it will improve up to infinity. This is the main thing, especially initially, that the Tau developers (or rather users) advance the platform more and more.
If you are interested in participating in the discussion, join our Discord (https://discord.gg/qZtJs78
) and post your thoughts – we’d appreciate it! Also has finished designing the bounty claiming process, so people that worked on a bounty now can claim their reward by filling out the bounty claiming form (https://forms.gle/HvksdaavuJbu4PCV8
). Been also working on revamping the original post in the Bitcointalk-Thread. It contains a lot of broken links and generally is outdated, so he’s using the whitepaper to give it a complete overhaul. With the whitepaper release, the community also got a lot more active which was great to see and thus, he dedicated more time towards supporting the community.
Finished multiple milestones with regards to the Agoras Live website: 1. Question part where people post their requests and knowledge providers can help them with missing knowledge. 2. Have been through multiple iterations of how to approach the services in the website. How the service seeker can discover new people through the website. 3. Connected the limited, static categories on the website to add more diversity to it. By adding tags, it will be easier for service seekers to find what they are looking for. 4. Onboarding: Been working on adding an onboarding step for the user, so the user chooses categories of his interest and as a result, he will find the homepage to be more personalized towards him and his interests. 5. New section to the user profile added: The service that the knowledge provider can provide. Can be added as tags or free text. 6. Search: Can filter via free text and filter by country, language, etc. 7. Been working on how to display the knowledge providers on the platform.
Improved look of the Agoras Live front page: Looks more clean. Finetuned search options. Redesigned the header. It now has notification icons. If you query a knowledge provider for an appointment, he will receive a notification about the new appointment to be approved or rejected. You can also add a user to your favorites. Front page now randomly displays users. Also implemented email templates, e.g. a thank you email upon registration or an appointment reminder. What is left to do is the session list and then the basic engine will be ready. Also needs to implement the “questions” section.
Has switched towards development of TML related features. Been working mainly on the first order logic support. Has integrated the formula parser with the TML core functionality. With this being connected, we added to TML quantified Boolean function solving capability in the same way as we get the first order logic support. It’s worth mentioning that this feature is being supported by means of the main optimized BDD primitives that we already have in the TML engine. Looking forward to make this scalable in terms of formula sizes. It’s a matter of refining the Boolean solution and doing proper tests to show this milestone to the community in a proper way.
Have been discussing the feasibility of a token swap towards ERC20 from the Omni token with exchanges and internally with the team. Also has been discussing the social media strategy with Kilian. As we update with the new visual identity and the branding, it’s a good time to boost our social media channels and look ready for the next iteration of our look and feel. Continuing on the aspects of our visual identity and design, he’s been talking to quite a number of large agencies who have been involved in some of the larger projects in the software space. One being Phantom (https://phantom.land
) who designed the DeepMind website (https://deepmind.com
), the other one being Outcast (https://theoutcastagency.com
) who have been working with Intel and SalesForce. We aren’t sure yet with which company we go but it’s been good to get insight into how they work and which steps they’d take into getting our project out to the wider audience. That whole process has been a lot of research into what kind of agencies we’d want to get involved with. Also, with the release of the whitepaper being such a big milestone in the history of the company, he’s been doing a lot of reading of that paper. We’re also looking to get more manpower involved with the TML website. Also going to hire a frontend developer for the website and the backend will be done according to Ohad’s requirements. Also, as a response of the community’s feedback towards the Omni deck not being user friendly, he did some outreach to the Omni team and introduced them to a partner exchange for Agoras Live. They have an “exchange-in-a-box” service which may help Omni to have a much more usable interface for the Omni Dex, so hopefully they will be working together to improve the usability of the Omni Dex.
Finished writing the community draft of the whitepaper. The final version will contain changes according to the community’s feedback and more elaboration on more topics that weren’t inserted in the current paper, including logics for law and about the full process of Tau. And, as usual, he’s been doing more research of second order logic, specifically, Boolean options and also analyzing the situation where the formulas in conjunctive normal form trying to extract some information from such a cnf. Also, what Juan mentioned about first order logic: People who are already familiar with TML will see that now with this change, the easiness of using TML got much more advanced. In first order formulas, expressing yourself has become much easier than before.
Q: What is the difference between Horn Second Order Logic and Krom Second Order Logic?
A: Horn and Krom are special cases of cnf (conjunctive normal form). Conjunctive normal form means the formula has the form of n conjunction between clauses. This clause and this clause while each clause is a disjunction of atoms: It’s this or this or this or that. And now any formula can be written in conjunctive form. Any formula can be brought to this form. Krom is the case where each clause contains exactly two atoms and Horn is the case where at most one atom in every clause is positive – thre rest are negated, that’s the definition.
Q: Now that the whitepaper has been released, how do you think it will affect the work of the developers?
A: We see the whitepaper as being a roadmap of development for us, so it will essentially be the vision that we are working to implement. Of course, we have to turn it into much more specific tasks, but as you saw from the detailed progress from last month, that’s exactly what we do.
Q: When can we expect the new website?
A: We’ve just updated the website with the whitepaper and the new website should be launching after we get the branding done. There’s a lot of work to be done and a lot of considerations taking place. We have to get the graphics ready and the front end done. The branding is the most important step we have to get done and once that is complete, we will launch the new website.
Q: What needs to be resolved next before we get onto a solid US exchange?
A: With the whitepaper released, that’s probably been the biggest hurdle we had to get over. At this point, we still have to confirm some elements of the plan with the US regulators and we do need to have some sort of product available. Be that the TML release or Agoras Live, there needs to be something out for people to use. So, in conjunction with the whitepaper and approval from the US regulators, we need to have a product available to get onto US exchanges.
Q: Does the team still need to get bigger to reach cruising speed, if so, how much by and in which areas?
A: Of course, any development team would like to have as many resources as possible but working with the resources we that have right now, we are making significant progress towards the two development goals that we have, both the Agoras Live website and the TML engine. But we are bringing in at least two more resources in the near future but there’s no lack of work to be done and also there’s no lack of progress.
Q: Will Prof. Carmi continue to work in the team and if so, in what capacity?
A: Sure, Prof. Carmi will continue coordinating with us. Right now, he’s working on the mathematics of certain features in the derivatives market that Agoras is planned to have, and also ongoing research in relevant logic.
Q: Will you translate the whitepaper into other languages?
A: Yes, we expect translations of the whitepaper to occur. The most important languages that comprise our community, e.g. Chinese. What languages exactly, we cannot tell right now, but mainly the most prominent languages that comprise our community.
Q: Is the roadmap on the website still correct and, when will we move to the next step?
A: We will be revamping the website soon including the roadmap that will be a summary of what’s been published in the whitepaper but the old version of the roadmap on the website is no longer up-to-date.
Q: What are the requirements for Agoras to have its own chain?
A: If the question means why Agoras doesn’t have its own chain right now, well there is no special reason. We need to reach there and we will reach there.
Q: When Agoras switches to its own chain, will you need to create a new payments system from scratch?
A: No, we won’t have to. We will have to integrate with the new payment channel but that’s something we are planning to do anyway. We will be integrating with several exchanges and several payment channels so it won’t be a huge task. Most of the heavy lifting is in the wallet and key management which will be done on the client side but we’re already planning on having more than one payment gateway anyway so having one more is no problem.
Q: When can we see Tau work with a real practical example?
A: For examples of applications of TML, we are currently working on a TML tutorial and a set of demos. Two of our developers are currently working on it and it’s going to be a big part of our next release.
Q: How can we make speaking in formal languages easier, with an example?
A: Coming up with a usable and convenient formal language is a big task which maybe it’s even safe to say no one achieved up until today. But we solve this problem indirectly yet completely by not coming up with any language but letting languages to be created and evolve over time through the internet of languages. We don’t have any solution of how to make formal languages very easy for everyone. It will be a collaborative effort over Tau together to reach there over time. You can see in the whitepaper in the section 4.2 about “The Critical Mass and the Tau Chain Reaction”.
Q: What are the biggest limitations of Tau and, are they solvable?
A: TML cannot do everything that requires more than polynomial space to be done and there are infinitely many things like this. For example, you can look up x time or x space complete problems. We would want to say elementary but there is no elementary complete problem but there are complete problems in each of the levels of elementary. All those, TML cannot do because this is above polynomial space. Another drawback of TML which comes from the usage of BDDs is arithmetic. In particular, multiplication. Multiplication is highly inefficient in TML because of the nature of BDDs and of course BDDs bring so many more good things that even this drawback of slow multiplication is small compared to all the possibilities that this gives us. Another limitation, which we will emphasize in the next version of the whitepaper, is the satisfiability problem. The satisfiability problem of a formula without a model to ask whether a model exists – not a model checking like right now but to ask whether a model exists – this is undecidable already on very restricted classes as follows from Trakhtenbrot’s theory. So in particular, the containment problem, the scalability problem, the validity problem, they all are undecidable in TML as is and for them to be decidable, we need to restrict even more the expressive power and look at narrower fragments of the language. But again, this will be more emphasized in the next version of the whitepaper.
Q: It looks years for projects such as Maidsafe to build something mediocre, why should Agoras be able to do similar or better in less time?
A: Early on in the life of the Tau project, we’ve identified the computational resources marketplace as one of the possible applications of Tau, so it is very much on our roadmap. However, as you mentioned, there are some other projects, e.g. Filecoin, which is specifically focusing on the problem of storage. So even though it’s on our roadmap, we’re not there yet but we are watching closely what our competitors in this field are doing. While they haven’t yet delivered on their promise of an open and distributed storage network, we feel that at some point we will have more value to bring to the project. So distributed storage is on our roadmap but it’s not a priority for us right now but eventually we’ll get there.
Q: What are the requirements in scalability, e.g. permanent storage etc.?
A: We haven’t answered that question yet.
Q: Will Tau be able to run on a mobile phone?
A: Definitely, Yes. We’re planning on being available on all computational platforms, be it a server, laptop, phone or an iPad type of device.
Q: Given a vast trove of knowledge, how can Tau determine relevance? Can it also build defenses against spam attacks and garbage data?
A: Tau doesn’t offer any predetermined solution to this. It is basically all up to the user. The user will have to define what’s criminal and what’s not. Of course, most users will not bother with defining this but they will be able to automatically agree to people who already defined it and by that import their definitions. So bottom line: It’s really up to the users.
Q: What are your top priorities for the next three months?
A: Our goal for this year (2020) is to release a first version of Agoras Live and of TML.
Q: Ohad mentioned the following at the start of the year: Time for us to work on Agoras. We need to create the Agoras team and commence work. We made a major improvement in one of Agoras’ aspects in the form of theatrical breakthrough but we’re not ready yet to share the details publicly. Is there any further news or progress with the development of Agoras?
A: If the question is whether there has been more progress in the development of Agoras, specifically with regards to new discoveries for the derivatives market, then the answer is of course yes. Professor Carmi is now working on those inventions related to the derivatives market. We still keep them secret and of course, with Agoras Live, knowledge sharing for money is coming.
