Case Very easy case, you have 100 DAI/USDC/USDT. You wanna transfer some to your friend but you have no ETH in your wallet :( Okay, let's find the solution starting with DAI Simple Way Of course, you can “just transfer some dust ETH to the account” BUT: So let’s find another way // Another way Let's dive into the code //etherscan.io/toke /0x6b175474e89094c44da98b954eedeac495271d0f#code Scrolling it down… aand see that picture: // --- Approve by signature ---
function permit(address holder, address spender, uint256 nonce, uint256 expiry,
               bool allowed, uint8 v, bytes32 r, bytes32 s) external
{
   bytes32 digest =
       keccak256(abi.encodePacked(
           "\x19\x01",
           DOMAIN_SEPARATOR,
           keccak256(abi.encode(PERMIT_TYPEHASH,
                                 holder,
                                 spender,
                                 nonce,
                                 expiry,
                                 allowed))
   ));

   require(holder != address(0), "Dai/invalid-address-0");
   require(holder == ecrecover(digest, v, r, s), "Dai/invalid-permit");
   require(expiry == 0 || now <= expiry, "Dai/permit-expired");
   require(nonce == nonces[holder]++, "Dai/invalid-nonce");
   uint wad = allowed ? uint(-1) : 0;
   allowance[holder][spender] = wad;
   emit Approval(holder, spender, wad);
} There is a permit function(see reference ). //eips.ethereum.org/EIPS/eip-2612 Function designed to be callable from any account, so if you want to give allowance for transfer, you don’t need to make a transaction anymore. Rather, you can generate a permit signature off-chain and send it to your friend by any messanger, even WhatsApp :) Deeper explanation Arguments: holder - address who gives allowance spender - address who can spend allowance nonce - sequence number of permit (used to avoid ) replay attack expiry - deadline timestamp, if you didn’t use permit till that timestamp it will be invalidated allowed - boolean flag, if true you make infinite allowance, if false - revoke allowance v, r, s - ethereum signature, more details How that works: The key idea is elementary, the user makes the signature of “allowance” using own private key, then the contract can verify that using built-in ecrecover function. “Allowance” is just the set of parameters of permit (like holder, spender, etc.) and service constants (see EIP for details). Algorithm: User chooses parameters User calculates keccak256 hash of paraments + service info User signs hash from the previous step User sends signature and parameters to friend off-chain Friend sent a transaction with the permit and transfer tokens from the users’ account What about USDC/USDT ? USDC Here is the source code, basically, there is similar mechanics with the permit. But for one-time transfers is better to use function. contract transferWithAuthorization USDT Here is the souce code contract USDT doesn’t have permit mechanics and it’s cannot be implemented since the contract is non-upgradable.

I have close Brazilian friends. Talented, tech-savvy, and extremely creative, my friends come from a diversity of professional backgrounds in software engineering, project management, information technology, design, and marketing. Rarely a dull moment when we connect, they have become like an extended family to me. When I told them I was researching and writing about the space industry in Brazil, they were both enthusiastic and a bit surprised. Space efforts at home emerge in the media on a relatively sporadic basis… The famous astrophysicist recently on Brazil along these lines. The letter is part of the Brazilian Portuguese edition of his book (2019). Dr. Tyson points out the importance of Brazil’s legacy in aviation and aeronautics with its home-grown and publicly traded aerospace conglomerate, . Based in the state of São Paulo since 1969, EMBRAER is a robust powerhouse that designs, manufactures, and sells aircraft and its parts for commercial, business, and military uses. Tyson also highlights the achievements of the first Brazilian astronaut, Lt. Col. Marcos Pontes, who flew on board the Russian Soyuz TMA-8   to the International Space Station. Since 2018, Pontes serves as Minister of State at the (Ministry of Science, Technology, and Innovation). Dr. Neil deGrasse Tyson shared his point of view Letters from an Astrophysicist Empresa Brasileira de Aeronáutica - EMBRAER Ministério da Ciência, Tecnologia e Inovações - MCTI Pontes and fellow crew members at the International Space Station. 2006 I wanted to offer a different angle of inquiry to my readers. Momentum, energy, and vibrancy dominate the tech startup ecosystem in Brazil.  This tech startup dynamism is especially evident in the city and state of São Paulo. If I borrow the philosophical , which explain that energy can neither be created nor destroyed in a given system - only converted from one form of energy to another, I ask myself the following questions. Can the space industry in Brazil also leverage the energy and vibrancy currently present in its tech startup ecosystem? With so much tech momentum, what's the status of space startups in Brazil? principles and questions from the laws of physics Setting the Context: The Startup Vibrancy Rich in precious natural resources and , Brazil is also the largest country in Latin America. The city of São Paulo, which is home to most of my friends, is one of the most populous cities in the Western Hemisphere. The University of São Paulo is by The World University Rankings. With some of the best academic programs and research in STEM (Science, Technology, Engineering and Mathematics), it is no surprise that . The city hosts the innovation and data centers of global titans such as Microsoft, Google, and Facebook. São Paulo is also the regional headquarters for Airbnb, Netflix, and Amazon. among the top world economies ranked in the top 100 the city is also full of tech companies and startups The startup ecosystem in São Paulo city is an impressively fine-tuned conveyer belt. In the year 2019, after the United States and China as the country in the world with the most tech startups that reach unicorn status. Unicorns are startups valued at US$ 1 billion or above. Brazil shared this spot with Germany. Some of these Brazilian tech unicorns leverage mobile gaming technologies, fintech, service delivery, healthcare, and real estate. Several unicorns are based in the city of São Paulo. Brazil ranked third Brazil has become an attractive market for venture capital and investors. In fact, it is the country in Latin America with the . The influx of venture capital reached an approximate US$ 2.49 billion in 2019. According to The , investments spread across 222 deals. The amount in 2018 totaled US$ 1.3 billion. Additionally, there is also the recent , which has heavily invested in Brazilian startups. most venture capital funds for its startups Association for Private Capital Investment in Latin America - LAVCA SoftBank-led Latin America tech fund of US$ 5 billion This startup boom in Brazil dates back to the late 1990s and early 2000s. With access to the Internet and increased web and mobile connectivity, the cascade of technologies, businesses, and startups followed. This growth is especially prevalent in the IT and tech worlds including, software development, cloud computing, artificial intelligence, Internet of Things - IoT, and mobile gaming. in 2018 beat the global average yearly increase with a solid 9.8%. Brazilian software developers and IT professionals are in top demand as well. Brazil is one of the for IT. Frequent international events and trade shows continue to position Brazil’s tech leadership in the region. Surprisingly, none of these unicorns relate to the space industry… Brazil’s IT market top outsourcing destinations The Case for Space Startups In the space industry, startups can be bold and efficient. With initial shorter cycles for experimentation and iteration, controlled risks facilitate scientific and technological breakthroughs. Today’s big global space players were once just startups and ideas. However, numerous space startups face the common challenge of rallying investment and venture capital with a length of time and effort greater than for other tech startups. In this sense, and despite growing interest in the global space economy, many tech entrepreneurs have remained at the periphery of Brazil's space industry. There are a few and remarkable space entpreneurs, however, which are currently driving innovation in the space startup ecosystem. I met earlier this fall. Lucas is the CEO and Founder of the space startup . Based in São Carlos in the state of São Paulo, Airvantis works in tandem with private and public partners in Brazil and overseas for space science. The company also has activities in the United States. It is part of the international network of startups in the . Lucas Fonseca Airvantis New York Space Alliance (NYSA) Lucas Fonseca, CEO and Founder of Airvantis. November 2020. Airvantis . It also serves as an incubator and innovation center for the collaborative . Garatéa-L is the first proposed Brazilian lunar commercial space mission. On its lunar orbit, the mission would test the survival of specific bacteria and fungi. sends scientific experiments to the International Space Station Mission Garatéa - L Lucas was born and raised in Santos in the state of São Paulo. His interests in space start early on in childhood. Lucas remembers growing up in the eighties in Brazil. Science fiction masterpieces and iconic space operas surfaced during this decade. These include E.T., Blade Runner, 2010, Dune, Aliens, The Terminator, Star Wars Episodes V and VI, and many others. Without a clear path to pursue his space ambitions at home, but with a vision to be part of the incredible world showcased in films, Lucas pursued studies overseas. This path opened doors for him to work in international space missions. “I never gave up being a space guy. And this is hard in Brazil, especially when I went to university. We didn’t have a space course per se at the university, so I pursued mechatronic engineering as my path to the space industry… When I was invited to work for the Rosetta Mission after my studies in Space Systems Engineering in France… I realized it was an opportunity to land on a comet that was very unique.” The launched in 2004. During a period of 12 years, the mission achieved historic milestones. It was the first time that a spacecraft did a rendezvous to study and follow the comet 67P/Churyumov–Gerasimenko in its orbit around the sun. During its journey, the Rosetta spacecraft conducted flybys of Planet Earth, Mars, and the asteroids 21 Lutetia and 2867 Šteins. The Philae robotic lander on board the Rosetta spacecraft was also the first-ever to successfully deploy in 2014 on the surface of a comet. The Rosetta mission definitely made a deep impression on Lucas and his own sense of purpose. European Space Agency - ESA Rosetta mission “Brazil was a blue ocean for me. I thought maybe I could try to catch the new space movement in Brazil. That's why I decided to open my own company in Brazil in 2012…” Invited to speak often to other countries in Latin America about his career and entrepreneurial path, Lucas assesses the challenges of getting visibility and traction as a space startup. A lot of the media coverage in Brazil tends to focus on what is being done overseas at the expense of local efforts. The government space program is very established with intricate systems and structures. Its strength has been on space cooperation for satellites rather than rocket launches. However, the sparks of enthusiasm and motivation are needed across public and private sectors to build and rally support for space. “People have no idea that we have such a varied space program in Brazil…We should be proud of the things we do in Brazil. This is something that I’m trying to evangelize. How to talk about space. How to train the right person to reach out to the media… You cannot expect the media to come to us… We need to know how to sell it.” Music video. Dormiveglia . “Things are happening in the space industry… But we need to have this spark of people in Brazil that want to do it even if it’s hard. It’s possible to have a space startup just like a delivery service startup. It’s getting easier because it’s more accessible to send things to space or to work on things related to space… It doesn’t matter if you have a space background or not because the possibilities are huge. You can work in communications, satellite imagery, and so much more…” Startup-driven innovation is especially relevant to the world's older and more established space programs like in Brazil. Startup vibrancy is a good benchmark for the future health of a country’s role in the growing globalized space economy. In this respect, a consolidated effort across sectors in Brazil to generate awareness of local efforts matters. Lucas agrees with this. “When you do something different for others, people love it. If you like space and you like being entrepreneurial, it doesn’t matter if you have a space background or not. We need to work for our future in space. We cannot rely on the government alone to link up and build a huge ecosystem…” Looking Back to Look Ahead Brazil’s government-led space program is one of the oldest in the world. It was formally established in 1960. This is just two years after the officially set up shop in the United States in 1958, and years ahead of its home-grown conglomerate EMBRAER. National Aeronautics Space Administration - NASA The origins of Brazil’s program date to work of the Grupo de Organização da Comissão Nacional de Atividades Espaciais - GOCNAE (Organization Group of the National Commission of Space Activities). This commission was appointed by presidential decree for space exploration, travel, and research. The researchers at GOCNAE contributed in its early days to numerous scientific international projects. This dynamic changed abruptly under the authoritarian military regime (1964- 1985). During this turbulent time in Brazilian history, the (National Institute for Space Research) substituted GOCNAE. INPE is based in São José dos Campos in the state of São Paulo. It quickly becomes the technical and scientific backbone for Brazil’s space program. Instituto Nacional de Pesquisas Espaciais - INPE The for high atmospheric research are also developed early on. These rockets were launched multiple times as early as 1965. For the sake of comparison, reflect the beginnings of the usage of sounding rockets in the United States in the late 1940s. In South America, only Argentina managed to develop the capabilities of sounding rockets during this same period. SONDA sounding rockets series a historical summary from NASA’s first sounding rockets Under military rule, the construction of launch vehicles started in Brazil. A couple of the prototypes of the Veículo Lançador de Satélites - VSL (Satellite Launcher Vehicle) get launched. They do not complete the missions due to technical problems. Diplomatic relations worsen in the South American region, which was already suffering from grim military dictatorships. This shows just the extent to which Brazil's R&D in launchers and satellites further complicated foreign relations. declassified U.S. foreign intelligence report in 1982 Likewise, Brazil’s two and only launch sites were also built under military rule. The (Barreira do Inferno Launch Center) was constructed in 1965 under the wing of the Estado-Maior da Aeronáutica - EMAer (Air Force General Staff). A typical site for launching sounding rockets, CLBI is located on the far northeastern coast of Brazil. The (Alcântara Launch Center) was built in 1982 in the historic city of Alcântara. This is the closest launch site to the Earth's equator. Centro de Lançamento da Barreira do Inferno - CLBI Centro Espacial de Alcântara - CLA Post-military years and under democratic leadership, INPE became part of the newly-created (Ministry of Science, Technology, and Innovation) in 1985. With INPE’s early leadership, more than a dozen satellites launched successfully since the 1990s. Brazil’s first satellite launch for Earth observation in 1993 was onboard a U.S. commercial small launch vehicle, the Pegasus Rocket. The rocket launched from a NASA B-52 aircraft. The remains in operation today to support weather forecasting, monitoring the water level of rivers and dams, and for other purposes. Ministério da Ciência, Tecnologia e Inovações - MCTI Satélite de Coleta de Dados 1 - SCD-1 (Data Collection Satellite 1) In 1994, the Brazilian government created a civilian branch for its space program, the Agência Espacial Brasileira - AEB (Brazilian Space Agency). With a change in discretionary authority and a different regulatory capacity, AEB works in tandem with INPE. It focuses on joint space technological development programs and . international space cooperation agreements The year 2003 was a sobering year for spaceflight in Brazil and across the world. Just several months after the , which killed all seven crew members during atmospheric re-entry, the at the Alcântara Launch Center days before launch. The explosion cost the lives of 21 personnel. STS-107 Columbia Space Shuttle disaster Brazilian VLS-1 VO3 exploded A brief survey of Brazilian space history reveals difficult periods.  Despite this past, the strengths of the Brazilian space program in satellites and international scientific space missions pave the way for the future. For example, INPE advances scientific research and development, especially concerning . Preparations are currently underway for the launch of the new . This launch is scheduled for 2021 from India. numerous small satellite missions Amazônia-1 satellite Space-minded entrepreneurs, like Lucas Fonseca, continue to invest in Brazil's space startup ecosystem. In conjunction with 11 startups, Airvantis is now part of the newly created (Alliance of Brazilian Space Startups). Launched in October 2020, this alliance has been set up in the city of Alcântara. The members wanted to pay tribute to the sacrifices made in the quest for space research, travel, and exploration. By leveraging the economic opportunities for Brazilian space startups in the domestic and global space markets, the alliance also wants to create a new chapter in the economic life of a former colonial town. Aliança das Startups Espaciais Brasileiras - ASB Some additional recent developments: - . The newly created (Mixed Parliamentary Front for the Brazilian Space Program) is composed of 186 deputies and 24 senators from across party lines. This parliamentary front emerges in Brazil to strengthen the cause and its support to its space industry. February 2020 Frente Parlamentar Mista para o Programa Espacial Brasileiro - FPMPEB - .

March 2019 Technology Safeguards Agreement - TSA - . The AEB signs an agreement to be part of the . November 2020 Global Spaceport Alliance Sound bites: Space Is A Positive-Sum Industry The modern space industry is not a zero-sum endeavor. It cannot be led by the government alone, the private sector, or just the dreams of startups. Space research, travel, and exploration are expensive. It takes . It also takes a village of people: space-minded entrepreneurs, advocates, government leaders, experts, artists, communicators, investors, and many others with a positive-sum mindset to scale up healthy space ecosystems. long-term thinking and sustained effort Brazil currently has at its fingertips competitive advantages. Tech unicorns are maturing and paving the way for new ones at one of the highest growth rates in the world. There’s already a colossal influx of venture capital funds for these startups that surpass the billions of dollars every year. Brazil's history shows us an established and veteran space program. It has powerful expertise and leadership in aviation and aeronautics. It has engineering and research programs ranked as the top in the world. This perfect mix may well renew enthusiasm at home and overseas to consolidate a vibrant Brazilian space startup ecosystem. New minds and fresh ideas can illuminate the way to Brazil’s new spacefaring future. I trust there’s a cadre of Brazilian entrepreneurs and investors like Lucas already looking forward to setting a steady course for space. The global space economy is growing at an accelerated rate. I hope that by giving visibility to the current space science efforts in Brazil, the space startup community leverages the momentum and energy already there for its tech unicorns. The payoff is out of this world.

The HEX story started one day Sir Richard was in his castle.

GAME of CRYPTOS [Chapter 6] — The HEX Kingdom

Back in 2018 I was finishing my graduation in Computer Science, and for my graduation final project I decided to work with transparency in governments, specifically with the Chamber of Deputies open data. Here in Brazil, our deputies have a monthly quota to perform their job. Let’s say that some deputy needs to buy a flight ticket or buy gas to the car in order to go to a meeting, he or she can use this monthly quota to do that. However, this money is public, therefore there are some rules to use it. One specific rule caught my attention, and it says that the deputies cannot use the money to buy a product or a service with companies that he or she is a partner, or a relative until third degree is a partner. With that information in mind I wondered if it would be possible to discover whether a deputy was using this quota illegally. So that was the goal of my work, to discover possible fraud patterns inside the open data that the Chamber o Deputies provides regarding the deputies expenses. During the project I also tried to find if some deputy used the money with a given company that provided funds to his campaign back in 2014, the year that they were elected, but it is a good information for our society. which is not illegal To perform all that I decided to use a graph oriented . I chose OrientDB as the DBMS because of the query language derived from SQL. In the next sections I will explain the whole process to achieve those goals. database Open Data The first thing that I had to do was obtain the data. First I downloaded the deputies expenses report from 2017 from this link: . There are a lot of file options to download, I worked with a CSV file to import the data in . After obtaining the expenses report, I had to obtain the campaign donations to the deputies in 2014 elections, and you can find in this link: . It’s also a CSV file with all the donations for each deputy campaign. CEAP open data OrientDB TSE open data Data Model Once I had the data files with me, I was able to analyse it and build a data model. A data model is used to provide a general vision of how the information will be organized inside the database, along with the data properties and relationships. The data model was built following the GRAPHED model, that proposes a way to model data for graph databases. The image below is the model that I built trying to evidence the possible fraud patterns mentioned. Unfortunately the model is in Portuguese, but we can see that the boxes will turn into vertices inside the database, and the arrows express how the boxes / vertices relate to each other. The left box named “Parlamentar” represents a deputy, and we can see that a deputy can perform multiples “Transação” or transactions, while transactions are usually provided by a “Empresa fornecedora” or supplying company. And at the same time I modeled in a way that a company can also perform transactions that are donated to a deputy. With that pattern we can discover if a deputy used the monthly quota money with companies that donated money to the deputy’s campaign. Also we can see that a deputy can be a “Socio_de” or partner of a company, and that a deputy has relatives that can also be partners of a company. With that we can discover if a deputy used the money with companies that he or a relative is a partner. ETL Once the data model was built, it was time to write some code to import all that data to OrientDB. OrientDB is written in Java, and there is a good interface with Java language, therefore I wrote an ETL in Java that read the CSV files and saved the information in OrientDB with all it’s properties and relationships following the data model. The code is open and can be found in github through this link: . CEAP_ETL The only point worth noticing here is that I had to be constantly checking if some vertex were already persisted in the database, in order to avoid two vertices representing the same deputy. The same goes for the supplying companies. The expenses report from 2017 had 209496 transactions and took 16 hours to finish the import process, in a Ubuntu 16–04 LTS, Intel Core i5–5200U CPU 2.20GHz * 4 and 6 Gb RAM machine. The donations file had to be filtered to use only federal deputies and the final version had 19302 donations and took 5 hours to finish being imported. Discovering Patterns With the database holding the data and structured according to the data model, I was able to use the OrientDB tools for my advantage and find some interesting results. In OrientDB if you want to find some specific pattern inside your graph you can use the operator. Let’s see the query below: MATCH {class: Parlamentar, as: p}−RealizaTransacao−>{class: Transacao ,as: t}−FornecidaPor−>{class: EmpresaFornecedora, as: e},{as: e}−RealizaTransacao−>{class: Transacao, as: t2}−FornecidaPara−> {as: p} $elements MATCH RETURN That query is pretty descriptive, we can see that it tries to find a pattern inside that graph that has a deputy “p” that executes a transaction “t” supplied by a company “e”. And the same company “e” executes a donation “t2” that is donated to the same deputy “p” declared in the beginning. Pretty simple, right? The image below shows the result So the result shows us that seven deputies used the monthly quota money with companies that donated money to them in 2014. The light brown vertex represents a deputy, the dark brown vertex represents a company and the purple vertex represents transactions. The picture is hard to see the patterns because it is trying to show the whole result, the image below shows the pattern in more details: Here we can see that some deputy received one donation from a company and performed three transactions with the same company. Again it is not illegal to do that but it is important to know these kind of information. But what about the fraud patterns? Unfortunately, the deputies relatives information is not public. One way out would be to built a web scraper and retrieve that information from Facebook, Twitter and other sites. But to validate the model and the whole process I inserted fake data to simulate the fraud scenarios, and hopefully if the Chamber of Deputies has this kind of data they could use the same process to inspect the deputies expenses. The query below was built to find a possible fraud pattern in the graph using the fake data that I’ve mentioned. {class: Parlamentar, as: p}−RealizaTransacao−>{class: Transacao, as: t}−FornecidaPor−>{class: EmpresaFornecedora, as: e},{as: p}−Socio_De−> {as: e} $elements MATCH RETURN Here we can see that the pattern looks for a deputy “p” that executes a transaction “t” supplied by a company “e”, and the same deputy “p” is a partner of the same company “e” defined before. This is a fraud pattern inside the graph, the image below shows the result. In the image we can see that the deputy in light brown vertex is associated to a company in a dark brown vertex, at the same time the deputy executed several transactions supplied by the same company. As I said before if the Chamber of Deputies has information regarding the companies that the deputy is a partner, they can approach this problem using graphs instead of relational structures. Finally, the query below shows the last pattern that tries to find if the deputy relative is a partner of a company that he or she used money to buy a product or a service. {class: Parlamentar, as: p}−RealizaTransacao−> {class: Transacao ,as: t}−FornecidaPor−> {class: EmpresaFornecedora, as: e},{as: p} −Parente_De−>{class: Pessoa, as: p2}−Socio_De−>{as: e} $elements MATCH RETURN The query follows the same approach as the other ones, the difference is that now the deputy “p” is a relative of a person “p2” and the person is a partner of the previously defined company. The result is shown below (Also using fake data). Transparency After all that process the project goal was achieved, but all that discoveries along with others that I will show next, had to be published so everyone could see whether our deputies are using the money correctly or not. For that I’ve built a web system in Ruby on Rails that uses HTTP to communicate with OrientDB, retrieve the result from the queries above and display a graph in the system. The system also displays other information regarding the expenses report from 2017. The query below displays the parties that most used the monthly quota in 2017. SgPartido, (SgPartido) Parlamentar SgPartido select count from GROUP BY The chart above was displayed in the screen after the system sent a HTTP request for OrientDB and retrieved the result as JSON. The JSON was passed to a Javascript chart library known as Highchart.js. With that we are able to see that PMDB was the party that most used the money in 2017. Here we can see the similarity with the SQL language, which makes real easy to adapt to this NoSQL DBMS. Other interesting information is what they spend the money with. The query below finds that. TxtFornecedor, in ("FornecidaPor").size() as servicos EmpresaFornecedora servicos desc 15 select from order by limit With that we can see that the companies that most supply services are traveling ones. It makes sense since the majority of the deputies comes from other states, and they need to travel for business for example. Again we see the similarity with SQL language, however, OrientDB allow us to get how much edges of type “FornecidaPor”, which means supplied by, enters in the vertex of a company. For exemple 23529 edges of type “FornecidaPor” enters in the “Cia Aérea - GOL” vertex. So the query is basically returning the name of the company and how much edges of the type “FornecidaPor” enter in the vertex, ordered by the size of edges mentioned. Conclusion After the project was done I was able to draw some conclusions to the whole process Each problem has an ideal way to be solved. Graph databases are great to work with data that are closely related, and has complex relationships. Take for example the case where we need to look for the deputies relatives until the third degree, these kind of relationship is better modeled in graph structures instead of a table structure. OrientDB is a great multi-model DBMS. I forgot to mention but it also works with key-value pairs and documents. You can create classes for your vertices and edges and organize your data with these classes, which is really helpful when writing your queries. You can build hierarchy relationships and improve even more your queries. Finally, the last conclusion that I had is that graphs are great to expose relationships and it is a viable solution to find patterns with open data, and to provide transparency for our population.
