How are FPGAs used in trading?
A field-programmable gate array (FPGA) is a chip that can be programmed to suit whatever purpose you want, as often as you want it and wherever you need it. FPGAs provide multiple advantages, including low latency, high throughput and energy efficiency. To fully understand what FPGAs offer, imagine a performance spectrum. At one end, you have the central processing unit (CPU), which offers a generic set of instructions that can be combined to carry out an array of different tasks. This makes a CPU extremely flexible, and its behaviour can be defined through software. However, CPUs are also slow because they have to select from the available generic instructions to complete each task. In a sense, they’re a “jack of all trades, but a master of none”. At the other end of the spectrum sit application-specific integrated circuits (ASICs). These are potentially much faster because they have been built with a single task in mind, making them a “master of one trade”. This is the kind of chip people use to mine bitcoin, for example. The downside of ASICs is that they can’t be changed, and they cost time and money to develop. FPGAs offer a perfect middle ground: they can be significantly faster than a CPU and are more flexible than ASICs. FPGAs contain thousands, sometimes even millions, of so-called core logic blocks (CLBs). These blocks can be configured and combined to process any task that can be solved by a CPU. Compared with a CPU, FPGAs aren’t burdened by surplus hardware that would otherwise slow you down. They can therefore be used to carry out specific tasks quickly and effectively, and can even process several tasks simultaneously. These characteristics make them popular across a wide range of sectors, from aerospace to medical engineering and security systems, and of course finance. How are FPGAs used in the financial services sector? Speed and versatility are particularly important when buying or selling stocks and other securities. In the era of electronic trading, decisions are made in the blink of an eye. As prices change and orders come and go, companies are fed new information from exchanges and other sources via high-speed networks. This information arrives at high speeds, with time measured in nanoseconds. The sheer volume and speed of data demands a high bandwidth to process it all. Specialized trading algorithms make use of the new information in order to make trades. FPGAs provide the perfect platform to develop these applications, as they allow you to bypass non-essential software as well as generic-purpose hardware. How do market makers use FPGAs to provide liquidity? As a market maker, IMC provides liquidity to buyers and sellers of financial instruments. This requires us to price every instrument we trade and to react to the market accordingly. Valuation is a view on what the price of an asset should be, which is handled by our traders and our automated pricing algorithms. When a counterpart wants to buy or sell an asset on a trading venue, our role is to always be there and offer, or bid, a fair price for the asset. FPGAs enable us to perform this key function in the most efficient way possible. At IMC, we keep a close eye on emerging technologies that can potentially improve our business. We began working with FPGAs more than a decade ago and are constantly exploring ways to develop this evolving technology. We work in a competitive industry, so our engineers have to be on their toes to make sure we’re continuously improving. What does an FPGA engineer do? Being an FPGA engineer is all about learning and identifying new solutions to challenges as they arise. A software developer can write code in a software language and know within seconds whether it works, and so deploy it quickly. However, the code will have to go through several abstraction layers and generic hardware components. Although you can deploy the code quickly, you do not get the fastest possible outcome. As an FPGA engineer, it may take two to three hours of compilation time before you know whether your adjustment will result in the outcome you want. However, you can increase performance at the cost of more engineering time. The day-to-day challenge you face is how to make the process as efficient as possible with the given trade-offs while pushing the boundaries of the FPGA technology. Skills needed to be an FPGA engineer Things change extremely rapidly in the trading world, and agility is the name of the game. Unsurprisingly, FPGA engineers tend to enjoy a challenge. To work as an FGPA engineer at a company like IMC, you have to be a great problem-solver, a quick learner and highly adaptable. What makes IMC a great fit for an FPGA engineer? IMC offers a great team dynamic. We are a smaller company than many larger technology or finance houses, and we operate very much like a family unit. This means that, as a graduate engineer, you’ll never be far from the action, and you’ll be able to make an impact from day one. Another key difference is that you’ll get to see the final outcome of your work. If you come up with an idea, we’ll give you the chance to make it work. If it does, you’ll see the results put into practice in a matter of days, which is always a great feeling. If it doesn’t, you’ll get to find out why – so there’s an opportunity to learn and improve for next time. Ultimately, working at IMC is about having skin in the game. You’ll be entrusted with making your own decisions. And you’ll be working side by side with super smart people who are open-minded and always interested in hearing your ideas. Market making is a technology-dependent process, and we’re all in this together.

A cryptocurrency (or crypto currency) is a digital asset
Main article:Blockchain The validity of each cryptocurrency's coins is provided by a blockchain. A blockchain is a continuously growing list of records), called blocks, which are linked and secured using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way". For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority. Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a blockchain. Blockchains solve the double-spendingproblem without the need of a trusted authority or central server), assuming no 51% attack (that has worked against several cryptocurrencies).
Cryptocurrencies use various timestamping schemes to "prove" the validity of transactions added to the blockchain ledger without the need for a trusted third party. The first timestamping scheme invented was the proof-of-work scheme. The most widely used proof-of-work schemes are based on SHA-256 and scrypt. Some other hashing algorithms that are used for proof-of-work include CryptoNight, Blake), SHA-3, and X11#X11). The proof-of-stake is a method of securing a cryptocurrency network and achieving distributed consensus through requesting users to show ownership of a certain amount of currency. It is different from proof-of-work systems that run difficult hashing algorithms to validate electronic transactions. The scheme is largely dependent on the coin, and there's currently no standard form of it. Some cryptocurrencies use a combined proof-of-work/proof-of-stake scheme.
📷Hashcoin mine In cryptocurrency networks, mining is a validation of transactions. For this effort, successful miners obtain new cryptocurrency as a reward. The reward decreases transaction fees by creating a complementary incentive to contribute to the processing power of the network. The rate of generating hashes, which validate any transaction, has been increased by the use of specialized machines such as FPGAs and ASICs running complex hashing algorithms like SHA-256 and Scrypt. This arms race for cheaper-yet-efficient machines has been on since the day the first cryptocurrency, bitcoin, was introduced in 2009. With more people venturing into the world of virtual currency, generating hashes for this validation has become far more complex over the years, with miners having to invest large sums of money on employing multiple high performance ASICs. Thus the value of the currency obtained for finding a hash often does not justify the amount of money spent on setting up the machines, the cooling facilities to overcome the enormous amount of heat they produce, and the electricity required to run them. Some miners pool resources, sharing their processing power over a network to split the reward equally, according to the amount of work they contributed to the probability of finding a block). A "share" is awarded to members of the mining pool who present a valid partial proof-of-work. As of February 2018, the Chinese Government halted trading of virtual currency, banned initial coin offerings and shut down mining. Some Chinese miners have since relocated to Canada. One company is operating data centers for mining operations at Canadian oil and gas field sites, due to low gas prices. In June 2018, Hydro Quebec proposed to the provincial government to allocate 500 MW to crypto companies for mining. According to a February 2018 report from Fortune, Iceland has become a haven for cryptocurrency miners in part because of its cheap electricity. Prices are contained because nearly all of the country's energy comes from renewable sources, prompting more mining companies to consider opening operations in Iceland. In March 2018, a town in Upstate New York put an 18-month moratorium on all cryptocurrency mining in an effort to preserve natural resources and the "character and direction" of the city.
GPU price rise
An increase in cryptocurrency mining increased the demand of graphics cards (GPU) in 2017. Popular favorites of cryptocurrency miners such as Nvidia's GTX 1060 and GTX 1070 graphics cards, as well as AMD's RX 570 and RX 580 GPUs, doubled or tripled in price – or were out of stock. A GTX 1070 Ti which was released at a price of $450 sold for as much as $1100. Another popular card GTX 1060's 6 GB model was released at an MSRP of $250, sold for almost $500. RX 570 and RX 580 cards from AMD were out of stock for almost a year. Miners regularly buy up the entire stock of new GPU's as soon as they are available. Nvidia has asked retailers to do what they can when it comes to selling GPUs to gamers instead of miners. "Gamers come first for Nvidia," said Boris Böhles, PR manager for Nvidia in the German region.
📷An example paper printable bitcoin wallet consisting of one bitcoin address for receiving and the corresponding private key for spendingMain article:Cryptocurrency wallet A cryptocurrency wallet stores the public and private "keys" or "addresses" which can be used to receive or spend the cryptocurrency. With the private key, it is possible to write in the public ledger, effectively spending the associated cryptocurrency. With the public key, it is possible for others to send currency to the wallet.
Bitcoin is pseudonymous rather than anonymous in that the cryptocurrency within a wallet is not tied to people, but rather to one or more specific keys (or "addresses"). Thereby, bitcoin owners are not identifiable, but all transactions are publicly available in the blockchain. Still, cryptocurrency exchanges are often required by law to collect the personal information of their users. Additions such as Zerocoin, Zerocash and CryptoNote have been suggested, which would allow for additional anonymity and fungibility.
Meaning of Field-Programmable Gate Array It is an early mining equipment which was in vogue and leading Bitcoin miner in 2010 to 2013 before it became obsolete and replaced by ASIC Miner. FPGA had upto 25GH/S mining power. These miners have been built around Field Programmable Gate Array or FPGA mining technology, the latest breakthrough in crypto mining. FPGA mining makes use of the new generation of FPGA chips ... Aber es geht auch anders. Es dauerte nicht lange, da kamen die ersten FPGAs (Field Programmable Gate Array) auf den Mark. Diese Chips leisten genau so viel wie aktuelle Grafikkarten, verbrauchen dabei aber wesentlich weniger Strom. Mittlerweile sind wir aber bei den ASICs (Application-Specific Integrated Circuit) angekommen. During the last years, the bitcoin mining ecosystem has been experiencing important changes. At the beginning, it was possible to mine bitcoin with a CPU processor, but later, it was possible to do it with GPUs. After it, GPU mining was replaced by FPGA and ASIC miners. What Is FPGA?
