COVID-19 is the abbreviated name for coronavirus disease 2019, a respiratory disease caused by a novel coronavirus strain called SARS-CoV-2. COVID-19 was first detected in Wuhan City, China and the outbreak was declared a public health emergency of international concern on January 30, 2020 by the World Health Organization (WHO). On March 11, the WHO stated that the COVID-19 outbreak is characterized as a pandemic, meaning worldwide spread. Nonpharmaceutical interventions (NPIs) such as social distancing, quarantine, and school and workplace closure were put in place to slow the spread of the virus.

Barcelona (/ˌbɑːrsəˈloʊnə/ BAR-sə-LOH-nə, Catalan: [bəɾsəˈlonə], Spanish: [baɾθeˈlona]) is a city on the coast of northeastern Spain. It is the capital and largest city of the autonomous community of Catalonia, as well as the second most populous municipality of Spain. With a population of 1.6 million within city limits, its urban area extends to numerous neighbouring municipalities within the Province of Barcelona and is home to around 4.8 million people, making it the fifth most populous urban area in the European Union after Paris, the Ruhr area, Madrid, and Milan. It is one of the largest metropolises on the Mediterranean Sea, located on the coast between the mouths of the rivers Llobregat and Besòs, and bounded to the west by the Serra de Collserola mountain range, the tallest peak of which is 512 metres (1,680 feet) high.

Founded as a Roman city, in the Middle Ages Barcelona became the capital of the County of Barcelona. After joining with the Kingdom of Aragon to form the confederation of the Crown of Aragon, Barcelona, which continued to be the capital of the Principality of Catalonia, became the most important city in the Crown of Aragon and the main economic and administrative centre of the Crown, only to be overtaken by Valencia, wrested from Arab domination by the Catalans, shortly before the dynastic union between the Crown of Castile and the Crown of Aragon in 1492. Barcelona has a rich cultural heritage and is today an important cultural centre and a major tourist destination. Particularly renowned are the architectural works of Antoni Gaudí and Lluís Domènech i Montaner, which have been designated UNESCO World Heritage Sites. The city is home to two of the most prestigious universities in Spain: the University of Barcelona and Pompeu Fabra University. The headquarters of the Union for the Mediterranean are located in Barcelona. The city is known for hosting the 1992 Summer Olympics as well as world-class conferences and expositions and also many international sport tournaments.

Barcelona is a major cultural, economic, and financial centre in southwestern Europe, as well as the main biotech hub in Spain. As a leading world city, Barcelona's influence in global socio-economic affairs qualifies it for global city status (Beta +).

Barcelona is a transport hub, with the Port of Barcelona being one of Europe's principal seaports and busiest European passenger port, an international airport, Barcelona–El Prat Airport, which handles over 50 million passengers per year,an extensive motorway network, and a high-speed rail line with a link to France and the rest of Europe.

Rome (Italian and Latin: Roma [ˈroːma] ) is the capital city of Italy. It is also the capital of the Lazio region, the centre of the Metropolitan City of Rome, and a special comune named Comune di Roma Capitale. With 2,860,009 residents in 1,285 km2 (496.1 sq mi), Rome is the country's most populated comune and the third most populous city in the European Union by population within city limits. The Metropolitan City of Rome, with a population of 4,355,725 residents, is the most populous metropolitan city in Italy. Its metropolitan area is the third-most populous within Italy. Rome is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of the Tiber. Vatican City (the smallest country in the world) is an independent country inside the city boundaries of Rome, the only existing example of a country within a city. Rome is often referred to as the City of Seven Hills due to its geographic location, and also as the "Eternal City". Rome is generally considered to be the "cradle of Western Christian culture and civilization", and the center of the Catholic Church.

Rome's history spans 28 centuries. While Roman mythology dates the founding of Rome at around 753 BC, the site has been inhabited for much longer, making it a major human settlement for almost three millennia and one of the oldest continuously occupied cities in Europe. The city's early population originated from a mix of Latins, Etruscans, and Sabines. Eventually, the city successively became the capital of the Roman Kingdom, the Roman Republic and the Roman Empire, and is regarded by many as the first-ever Imperial city and metropolis. It was first called The Eternal City (Latin: Urbs Aeterna; Italian: La Città Eterna) by the Roman poet Tibullus in the 1st century BC, and the expression was also taken up by Ovid, Virgil, and Livy. Rome is also called "Caput Mundi" (Capital of the World). After the fall of the Empire in the west, which marked the beginning of the Middle Ages, Rome slowly fell under the political control of the Papacy, and in the 8th century, it became the capital of the Papal States, which lasted until 1870. Beginning with the Renaissance, almost all popes since Nicholas V (1447–1455) pursued a coherent architectural and urban programme over four hundred years, aimed at making the city the artistic and cultural centre of the world. In this way, Rome became first one of the major centres of the Renaissance, and then the birthplace of both the Baroque style and Neoclassicism. Famous artists, painters, sculptors, and architects made Rome the centre of their activity, creating masterpieces throughout the city. In 1871, Rome became the capital of the Kingdom of Italy, which, in 1946, became the Italian Republic.

In 2019, Rome was the 11th most visited city in the world, with 10.1 million tourists, the third most visited in the European Union, and the most popular tourist destination in Italy. Its historic centre is listed by UNESCO as a World Heritage Site. The host city for the 1960 Summer Olympics, Rome is also the seat of several specialised agencies of the United Nations, such as the Food and Agriculture Organization (FAO), the World Food Programme (WFP) and the International Fund for Agricultural Development (IFAD). The city also hosts the Secretariat of the Parliamentary Assembly of the Union for the Mediterranean (UfM) as well as the headquarters of many international businesses, such as Eni, Enel, TIM, Leonardo S.p.A., and national and international banks such as Unicredit and BNL. Rome's EUR business district is the home of many oil industry, the pharmaceutical industry, and financial services companies. The presence of renowned international brands in the city has made Rome an important centre of fashion and design, and the Cinecittà Studios have been the set of many Academy Award–winning movies.

Quantum computation utilizes quantum mechanical effects, such as superposition, entanglement, and interference, to perform computation. Classical computation relies on the ability to store and manipulate binary integers (bits) generally made from silicon transistors. Instead, quantum computers make use of quantum bits (qubits) that can have the value 0, 1, or a superposition of these 2 states. Leveraging superposition and entanglement to create states that scale exponentially with the number of qubits offers the potential for dramatic improvements in computation power compared to classical computers .

A quantum mechanical model of a computer was first conceived by physicist Paul Benioff in 1980, inspired by an Alan Turing paper written in 1936. Richard Feynman, then a professor at Caltech, described how quantum computers could be used to simulate physical systems in a paper published in 1982, titled "Simulating Physics with Computers." These ideas were developed by David Deutsch in 1985, describing the concept of a universal quantum computer to understand the mathematical potential that was possible. In 1994, Peter Shor developed “Shor’s algorithm,” allowing a quantum computer to perform factorization of large numbers significantly faster than the best classical algorithms .

The quantum states required to make quantum computing feasible are easily destroyed due to noise from unintended interactions with the environment or the imperfect implementation of quantum logical operations. Producing scalable quantum computers requires an effective error correction method that prepares the logical state, applies logic gates, and detects and corrects errors without introducing more errors into the system. An error correction method that reduces the overall number of errors present in the system is described as fault-tolerant, whereby one error does not spread to create more errors .

In 2020, Cardano held a Shelley upgrade that aimed to make its blockchain “50 to 100 times more decentralized” than other large blockchains. At the time , Hoskinson predicted that this would pave the way for hundreds of assets to run on its network.

The current CoinMarketCap ranking is #8912, with a live market cap of not available. The circulating supply is not available and a max. supply of 500 000 SYMM coins.

Symmetric is an Automated Market Maker (AMM) and a Decentralized Exchange (DEX), running on the Celo and Gnosis networks.Symmetric’s roadmap includes further development of use-cases (such as a launchpad, crypto index funds, crypto ETFs & ESG funds) and support for more networks in the future.

Symmetric is noncustodial, which means that users remain in control and are responsible for the crypto assets they stake, add or swap. Symmetric provides the infrastructure for staking, liquidity mining and token swaps but does not control or take possession of any crypto assets or tokens transacted by users (they remain locked in smart contracts).

We strongly recommend and encourage that all users complete thorough research and due diligence before adding any liquidity or executing any token swaps.

Initially Symmetric will only support MetaMask and Wallet Connect compatible wallets, but will be adding support for many more in the future.

‘SYMM’ is the ticker or symbol, for the Symmetric governance token. The token’s utility is to entitle token holders to participate in the governance of Symmetric and its ecosystem.

SYMM coins are issued as a reward to liquidity providers (in addition to their share of any applicable fees) & stakeholders adding value to the Symmetric ecosystem.

Symmetric’s team believes in the principles of a fair launch, which does not reward groups with large pre-mined token holdings prior to the product or service launch. Typically in an ICO, IDO or other type of token event, there is a large pre-mined allocation of coins to founders giving a quick secured reward. A fair launch has a smaller or no pre-mine and value flows out to beneficiaries after the launch of a project.

Symmetric’s governance token, or ‘SYMMs’ can be acquired through token swaps, completing pre-specified tasks on GitHub, liquidity mining and other value-adding activities.

Liquidity providers earn SYMM coins by staking coins or adding liquidity to pools or creating their own pools of whitelisted tokens.

Community members earn SYMM coins by actively working on the Symmetric product such as development work, bug bounties, events, marketing and community building.

The operations team earns SYMM tokens by actively supporting the Symmetric ecosystem; including ongoing development work, management and day to day operations.

Some SYMM coins are also converted each week into other coins that are held in the Symmetric risk fund as ‘collateralized protection’ for liquidity providers.

Our belief is that DeFi protocols, facilitating decentralised financial services should also be governed in a decentralised way by stakeholders to ensure interests remain aligned and that incentives and rewards flow back to value creators. To ensure this happens, Symmetric will be governed as a Decentralised Autonomous Organisation (DAO) where the voting power for important & consequential decisions, rests with the DAO members.

Liquidity providers who lose money due to an event such as a malicious attack, compromised or crashed asset, can put in a claim to the Symmetric risk fund.

This fund will grow over time with monthly token allocations and diversify concentrated asset positions by converting some SYMM coins each week into other crypto assets to be held by this fund as ‘collateralized protection’. This diversification will only begin once the pools have enough liquidity to withstand market impact costs. The risk fund helps reduce risk for liquidity providers, something we feel is necessary in todays DeFi market.

The fund will also be governed by the DAO and will continue to look for more capital efficient ways to boost protection for Symmetric users.
