Core tips

  1. Needlessly to say by the marketplace, 2019 will be destined to be the 12 months when giants begin to place sail within the Crypto marketplace. Although coin does not participate in the DeFi classification, this is plenty of to help make the entire Wall Street financial marketplace rethink the business enterprise reform of Fintech and Blockchain. The New York Times provides rumored that Facebook will launch a stable currency for social payments. Under the pioneering steps of predecessors such as for example Series, Facebook’s restructuring and generating its commercial value is definitely not really limited to stablecoins. In the foreseeable future, giants will compete to build up in their personal system. An open financial incentive system, liquidity, openness, and decentralization may also turn out to be an obstacle for giants to advance in this industry.
  2. I think the essential principles of information freedom also apply to the financial system. By creating a fresh decentralized financial marketplace, society will benefit from the impact of past information innovation. But this time around, it will alter value, cash and finance.
  3. Just because the Internet has effectively developed an information system parallel to the real world, cryptocurrency will set up a parallel economic infrastructure. And exactly like Internet innovation is not limited to local area networks, blockchains are not limited to private blockchains (Personal Blockchains).
  4. The new open financial infrastructure already exists. But it is still quite slow, costly, and difficult to use, similar to the Internet in 1992. Quick forward a couple of years and it will become fast, inexpensive and simple to use. Among the benefits of the Internet is that it can benefit us construct encrypted networks quicker, which is a high-class that did not exist in the early development of the web.
  5. Why do individuals choose applications built on open supply protocols instead of traditional centralized companies? You can find two answers: lower costs and regulatory benefits.
  6. In the crypto planet, launching a smart contract is the same as introducing a rocket. The goods of smart contracts are money. There is a fundamental and essential distinction between NASA rockets and wise contracts: the rocket’s code is closed supply while smart contracts are open supply.
    Joey Krug: Co-CIO of Pantera Capital, Founder of Augur
    A new economic infrastructure
    Blockchain and cryptocurrency will be the system of new finance. Just because the Internet is the system of new media, neither will be built overnight.
    Whenever we look back on the history of information access and the improvement of freedom of information, we will observe that no matter what indicators are used to measure, society is continually improving: education, the spread of tips and new technologies, per capita GDP and poverty rates.
    The initial sign of information innovation was the birth of the printing press, and information innovation continued to build up. Telegraph, telephone, radio stations, television, and the web. The Internet is very interesting. It mixes all the products of other information innovations: it is possible to listen to sounds, read texts, and watch videos via the web. You can certainly do all this anytime, anyplace! Different from information innovation in history, the Internet has not only completely transformed the way content material is obtained, but also decentralized the creation of content.
    Exactly what does this want to do with finance? Finance has not experienced similar innovations. Actually, the innovation of financial expertise is not at exactly the same level as the innovation brought about by the web for social information freedom. At best, it can be said that most transactions today are conducted electronically. However, the most vital part has not transformed: the creation of new tools, contracts and agreements. Today we nevertheless cannot develop a economic contract-such as derivatives, loan products or currency marketplace contracts.
    This notion sounds radical, and the degree of radicalization is not any less than the declaration in ancient times that folks apart from literati can write their own books.
    People might exclaim, “Don’t publishers control what they publish? They check out sensitive subjects!”
    Others cheered, “Imagine if individuals can article any content they want and will freely choose what they want to read?”
    I think exactly the same basics apply to the financial system. By creating a fresh decentralized financial marketplace, society will benefit from the impact of past information innovation. But this time around, it will alter value, cash and finance.
    Provided the regrettable financial marketplace conditions, we are not just attempting to create printing presses, telegraphs, and even televisions. Our goal is to make the financial sector jump directly to the decentralized level of Internet information freedom today.
    It is organic to think of currency as an expansion of speech. Even though you disagree, United Residents will effectively support this view. Just as people don’t need the Supreme Court’s case to recognize the fact that bytes that define information on a pc are speech, if money can be indicated in bytes, then money may also be speech.
    United Citizen: It had been a higher court decision in america in 2010.
    Why did you do that? What will ultimately be achieved?
    Just because the Internet has successfully created an information system parallel to the real world, cryptocurrency will create a parallel financial system. And just as Internet innovation is not limited to geographic area networks, blockchains are not limited to private blockchains.
    After Internet innovation, the rest of the companies are either “native Internet” or offline giants (much like publishers, music and streaming media/video/TV). A similar thing will happen here. The old economic giants either choose to adjust, support as well as eventually join this parallel system, or they will gradually disappear.
    This infrastructure will be borderless, cheap, fast, & most importantly, it will allow people to trade things they could not exchange before.
    Imagine if a new financial marketplace could possibly be developed. In this market, Goldman Sachs utilized to design a custom agreement worth huge amount of money, but now it only takes a few clicks. Exactly what will happen?
    This isn’t something that may happen in the foreseeable future, but something that already exists. But it is still quite slow, costly, and difficult to use, similar to the Internet in 1992. Quick forward a couple of years and it will become fast, inexpensive and simple to use. Among the benefits of the Internet is that it can benefit us construct encrypted networks quicker, which is a high-class that did not exist in the early development of the web. The reason that of this can occur is that the coordination and enforceability from the blockchain are relatively low priced. Everything may happen in a programmatic way, instead of giving trust to a certain organization, convinced that it will be fair, open and sincere. Way of doing things.
    So what can we do? For any financial system, basically two core components are needed: underlying resources and derivatives.
    The underlying assets are items that can be found in the real world: shares, bonds, commodities, etc.
    A derivative is a agreement that derives value through the performance from the underlying asset. For example, a derivative of Tesla share may give you the proper to get Tesla at a certain price at a certain date in the foreseeable future, or it might be a money settlement agreement to cover Tesla’s price today and The difference between costs after one month. A lot of the routines and value within the financial system rest in derivatives. Individuals will think, why must i buy some issues (underlying resources) whose costs will change instead of those whose costs can be created according to my unique targets and needs (derivatives)?
    Any healthy financial system requires a group of fundamental tools, such as for example:
  • Leverage-the multiple that you get or lose if the price tag on something rises by one dollar
  • Margin-Ability to borrow funds to pledge everything you already own to get more things
  • Accounting unit-something that can be exchanged stably (such as for example US dollars)
  • Exchange infrastructure-the location where assets are actually traded
  • Infrastructure for loan products and issuance-issuance of financial debt and equity instruments.
    Projects that can use these core tools can be divided into 3 categories: projects that issue underlying resources for the blockchain, projects based on underlying resources and other derivatives transactions.
    The current project can meet all of the needs of open financial infrastructure:
    Leverage: For example, the architecture of smart contracts can meet the needs for achieving leverage. Margin (and loan) requires a system like Dharma make it possible for people to borrow cryptocurrencies making use of additional cryptocurrencies as guarantee.
    Accounting unit: For accounting units, stable cryptocurrency is a challenge. It isn’t as easy as merely marking the U.S. dollar-depository banking institutions may unintentionally freeze accounts. An easier way is to create something like Machine, which is building an asset-backed tough currency. The initial decentralized stablecoin for the Ethereum blockchain. Actually, the stablecoin Dai will be backed by over-collateralizing additional cryptocurrencies. Despite the continuous controversy on the market, Dai nevertheless has the value of one dollar.
    Transaction system: 0x is an open protocol for decentralized dealings for the Ethereum blockchain. 0x will be building a massive amount trading system and developing methods for trading.
    Today’s blockchain community is building the underlying infrastructure necessary for a well-functioning financial system. This technique is suitable for multilateral marketplaces.
    Few traditional assets

I don’t think that traditional resources will migrate to the blockchain, and those assets for the chain may also face restrictions because of their effect on the real world.
Security tokens certainly are a good innovation from “9 to 10”, however they are not “0 to at least one 1” innovations just like the above projects. The greater the interaction between the real world and the blockchain, the more difficult the entire project-because the safety benefits of blockchain technology will quickly fade.
For example, if the owner of a Token-marked share loses his private key, his share may face recuperation. With the addition of more and more governance level agreements, these governance agreements will eventually change the entire ecosystem right into a Walls Street 2.0 data source having a smoother backend and fewer community blockchain interactions.
Some exceptions are Harbor, which attempts to tokenize real-world assets and make them tradeable on Ethereum. The advantage of that is that asset securitization can be executed at a lower cost while obtaining even more global liquidity-the last mentioned may be the greatest benefit. I believe that though it will be difficult to profit from this space, you will see a few gamers like Harbor dominate, & most of the value generated will be transferred to tokenized companies and assets.
For that issuance of debt, the Dharma protocol is very suitable and nearer to the digital currency world. For that derivatives of root assets, you can find projects like dYdX-a decentralized margin investing and an open source protocol based on Ethereum-based token derivatives investing.
For additional transactions, even though there is no on-chain-based asset, Augur, a decentralized trusted data source Oracle and prediction marketplace protocol may be used.
Although it only takes a several decades to tokenize almost all real-world assets, after the scale from the blockchain expands and there is a good channel for fiat currency to switch electronic currencies. These fresh financial agreements will be able to take off quickly, faster than Model 3 (Tesla) in orbital mode.
What about finance?
Blockchain technology is beneficial to multilateral markets-especially economic markets. Other make use of cases integrated using the economic market consist of: file storage market, such as for example Filecoin; computing energy market; prop marketplace in electronic video games; domain name marketplace, such as for example Handshake; regular betting/gambling, such as for example FunFair; sharing economy agreements, such as for example Origin. These projects will advertise the traditional decentralization motion: reduce the dimension of existing profitable companies and replace them with software program. As software is certainly replacing the world, some software program will replace others.
About currency and cash?
I think money and payments are one of the final areas affected by blockchain. I believe they will ultimately be converted by cryptocurrency. Although Bitcoin could become electronic gold, I don’t believe it will be as prosperous as currency: it is too unstable, was not designed as a currency, and contains no dynamic monetary policy (this is why gold is discontinued as a sociable payment Part of the means). Aside from large-scale collateral-backed reserves like Machine, in my opinion, currencies linked to fiat currencies cannot endure attacks.
Liquidity is king
A new financial system sounds thrilling and hopeful, nonetheless it can’t be effective without possible liquidity. What’s liquidity? You can think of it as a torrent of drinking water. Seafood can’t swim in a dry stream. On the other hand, water-filled channels maintain a small ecosystem. Imagine you buy Tesla share: in the event that you try to purchase $5,000 as well as your order will be packed immediately, from your own perspective, the marketplace is liquid. But if you decide to purchase $5,000 worth of items also it takes a day time to fill your order, then the market is certainly illiquid. To encourage liquidity, fair, easy, cheap and quick transactions are needed in every marketplace. The current blockchain-based financial marketplace doesn’t have most of the characteristics. Therefore, I really do not be expectant of to see a lot of liquidity and programs for a while.
Some people screamed that having less users implies that blockchain technology is useless. They may not have a deep knowledge of liquidity or the sources of liquidity. For fresh things to become adopted and widely accepted, it requires to offer an experience that is 10 times better than present issues. In blockchain technology, we do not however have this condition.
Lack of liquidity is a big constraint. If individuals cannot trade quickly and make a market because the execution from the transaction is too gradual or very costly, it is generally impossible to guide the market. As soon as these issues I discuss later are resolved, I really believe we will witness the steepest S-curve in the history of large-scale programs.
Leading the marketplace within the cryptocurrency world differs from building Web 2 2.0 applications, and you cannot simply begin more servers to cope with huge amounts of visitors. In the cryptocurrency planet, if you don’t have high system throughput, you can get any significant visitors, because liquidity brings liquidity. If traders cannot make a market in economic DApps, they cannot raise the liquidity of the marketplace.
Approximately open source agreement companies
What about companies built on all these open source resources?
The exchange of fiat currency and electronic currency appears to be a clear possibility to capture value. What else?
On top of these open source agreements, we can easily see a bunch of mini Red Hat-style enterprises flourish. These companies have almost unlimited opportunities to supply value-added services that induce value in a non-rent-seeking way. Some examples consist of: making it easier to construct smart contracts, supplying more secure tools for writing wise contracts, KYC/AML compliance, better transactions, guardianship solutions, dispute quality and arbitration tools, remittances, asset administration tools, etc.
In the traditional corporate world, I really believe that the most important way of value creation we will see in the moderate to long term would be to develop an easy-to-use interface on top of the protocol. We have just seen projects like Veil that try to develop a spin-off and sports betting site on top of Augur.
Why do people choose programs built on open source methods instead of traditional centralized companies? You can find two answers: lower costs and regulatory benefits.
reduce the cost
If the protocol is designed correctly, the protocol will never be forked and the usage charge will be reduced, charging the minimum charge level to execute the transaction without compromising the security from the network. For example, Augur adopted a nearly sacred approach called the Amazon . com Jeff Bezos creed, “Your profit percentage is certainly my [agreement] possibility.”
Therefore, through the perspective of fee ranges, there is no reason not to construct on open source agreements. If you keep your charges down by forking the agreement, you will sacrifice security. For example, if the cost of making sure the safety of a given network is certainly $1,000, and miners or gamblers can only get $500 in income, then they could have the economic incentive to accomplish evil. However, if they receives a commission $1,000, the system can adjust to their motives, therefore making sure security, and everyone for the network will get a satisfactory result.
This begs the question, “How will these companies make money?”
The answer would be to provide valuable and reasonably priced services. Implementing the Augur protocol and an individual user interface (UI), hosting it on AWS and deducting the $50 charge through the transaction will not last long, neither is it a lasting business model.
Providing liquidity for marketplace making, or taking chances as a investor, will always be rewarded by folks who are ready to purchase liquidity. Although competitors may exist, people are still ready to pay for quick liquidity.
We are beginning to witness the breakdown of regulatory compliance. Take Coinbase as an example. If they create and operate Bitcoin (as a centralized system), they will bear a lot more than their current operating model, which is to perform and make use of Bitcoin only for the Bitcoin blockchain. Compliance obligations.
In the former case, Coinbase will be characterized because the operator of Bitcoin, thus creating huge compliance obligations. Envision suffering the difficulty of transferring money from multiple anonymous users all over the world!
Instead, they only use Bitcoin and therefore only need to meet customer KYC/AML needs. In other words, these trading systems divide regulatory compliance obligations in an extremely segmented manner. Many of the benefits of wise contracts are that they can obtain a fairer, procedural, clear and open marketplace. In these marketplaces, things occur programmatically, and the rules are pre-coded and fair for everyone.
It is impossible to require an exchange to meet the needs greater than 150 jurisdictions, nonetheless it is entirely possible to completely comply with local jurisdiction requirements.
Similarly, for additional projects that are emerging (such as for example Veil), when investing and placing wagers in the country/region where the counterparty operates, KYC/AML can be carried out contrary to the counterparty, nonetheless it may not be essential to register as an exchange itself (because the ether Fang nodes can do this), Veil is just another trader for the P2P exchange. If Veil begins the business of fabricating markets or coordinating orders, the situation may be various, and it might need to sign up as an exchange. In any event, “Veils” in various geographic locations can be started and offer their own suitable interfaces to distributed protocols, such as for example Augur or 0x.
Back to “Company based on open source agreements”
I believe these types of companies will create plenty of value because they are in the industry where consumers interact probably the most. The most severe case is that if you certainly are a user of an application built on a decentralized protocol, once the application falls, you can continually restore it through the backup within the decentralized network.
Tasks built on open source agreements will highlight themselves in various ways, remove certain functions, add features, and facilitate customers or simplify the procedure. For example, in my opinion, people can create a multi-billion dollar company by developing an easy-to-use betting-style user interface on top of Augur. They will be the counterparty from the transaction to profit from the spread and be able to compete with projects like Wager365. As Jeff Bezos stated: their revenue is your possibility.
Businesses built on open source agreements sometimes forget an integral factor: Although the agreement performs many jobs related to the back-end/back-end, it does not promote marketing on its own. A lot of the company’s focus should shift to consumer acquisition and marketing. And don’t forget that it’s not really the job (or ability) to market your product, similar to the job of Google search is not to promote your website.
Three main problems facing decentralized finance

  • Freshman infrastructure
  • Scalability
  • The route of legal forex
    In terms of infrastructure, constructing something in cryptocurrency/blockchain is even more akin to building a rocket or biotechnology than constructing something similar to Snapchat. The programmer environment, language, and tools are so new within the cryptocurrency world-it helps it be very difficult to create something. That is like the early days of the web, creating a easy website is tough. On Ethereum, you can use Solidity to create smart contracts. Solidity goes one step beyond Bitcoin’s scripting language, but it can actually do not a lot of things. Only after 2015 will it be feasible to build these things. Testing Solidity can be time-consuming, since there is no good tests framework to test Solidity smart contracts. Truffle is among the several solutions, and it is challenging to use.
    The most important challenge would be to ensure that the written code is correct. You can find two aspects here: specification and implementation. When specifying the protocol design, ensuring that the technical specifications are logical is very time-consuming. Furthermore, the code must also conform to economic principles.
    It is very rare for cryptocurrencies to closely blend computer science and economics. If you do not handle both properly (ie, suitable incentives), in that case your system will not work, or worse, there may be an assault leading to devastation Sexual failure. This requires a long game theory argument on different assault vectors and feasible ways to fail. Once you have a specification, the next thing is to implement it. When you do that, it must specifically match the specification, otherwise the machine will never be able to perform the prepared operations.
    Once the code is written, multiple independent third celebrations must conduct safety audits, bug bounty programs, guide code reviews, write a large number of test programs, run static analysis tools that detect standard vulnerabilities, and ensure that it is critical to any key you rely on These steps from the code are executed.
    What do you think from the Rockets?
    If you’re NASA, you are building a rocket and can launch it later. You only have one chance to construct the rocket. Any errors within the rocket’s code may inadvertently lead it to explode. Of course, alternative rockets can be released, but if somebody is up to speed, the loss caused by the failure from the rocket is fairly expensive and can have tragic implications.
    In the crypto world, introducing a smart contract is the same as introducing a rocket. The goods of smart contracts are money. There is a essential and key distinction between NASA rockets and wise contracts: the rocket’s code is closed supply while smart contracts are open supply. This analogy is similar to a rocket in air travel, and anyone who would like to give orders can blow it up. Thanks to the open supply code, anyone can examine all the plans to attempt to discover an attack method, which is the challenge of writing protected smart contracts.
    Decentralized approach-use “autonomous generating” as a metaphor
    You can find two methods to develop a decentralized application. One is to be totally decentralized from day time one, and another would be to start to become relatively concentrated and gradually become more decentralized over time. This is similar to various methods of autonomous generating. For Tesla, it is possible to drive nearer to level 2 (partial automation) at the beginning and slowly enter level 5 (full automation).
    Alphabet’s multi-billion-dollar self-driving vehicle project Waymo, you’ll start at level 4-5 and await expansion and soon you can achieve autonomous driving in a safe and sound way. Cryptokitties or 0x adopts a Tesla design method, which is centralized to handle the user user interface and gradually open. On the other hand, Augur adopted a far more Waymo-style technique, taking a totally decentralized technique from the first day, attempting to improve the expertise and scalability for mass production.
    In terms of autonomous driving, I believe the Tesla-style approach can make more sense, because you can let end users in the real world test it. In my opinion, security and confidence issues make Waymo strategies more sensible within the crypto planet. Regardless, all issues are dependant on scalability issues, so when scalability issues are still limiting factors, you have more time and energy to iterate.
    What do you think of biotech companies?
    If you take a look at a biotech company, they usually possess a so-called pipeline, which is a series of drugs currently undergoing analysis and development. Furthermore, the company hopes that they can solve a series of unresolved research troubles, and in the process of doing therefore, they will ultimately have the ability to release a certain kind of medication that can provide benefits to the general public. These drugs usually go through three to four stages. Very first you can see a drug applicant, if it looks promising, then the next step is the start of the test. Sometimes it begins with animal tests, or sometimes it goes directly to human testing.
    The interesting thing about biotechnology is these companies (a lot of which are listed companies) are fundamentally necessary to solve research problems. And like encryption, you have all these unresolved analysis problems: such as for example computational scalability, proof of equity, information access issues, etc., you have to do these jobs on a certain timeline. People are eager to discover Ethereum discharge Casper (a Proof-of-Stake protocol), and folks are demanding that these unsolved computer science problems become solved within two to three yrs. Of course, the crypto planet continues to be in its early days, and I believe we will see this dynamic in the next 5-6 yrs (I would also underestimate it). From then on, I believe the crypto planet will look similar to traditional software growth.
    If essential milestones such as for example scalability and fiat currency entry are resolved, you should bet on what you think can do well. An awesome area of the crypto planet, which we will cover at length later, is the catalyst for most projects. Being an investor, you’ll find out who’s good at performing and building items that you think are of long-term value to the ecosystem and have a solid team, technical and economic foundation. So your bet is basically that if these problems are solved, then the success from the team is the utility from the large-scale application of the items they have built. In other words, pick those investments that can benefit the most through the team that is solving the problem. These investments will either create this long term or make it become created. Just like biotechnology, in the event that you try to forecast when this market will happen, you’ll fail, but choose basket of companies with excellent groups and products and keep them until they are adopted or fail. The chances of success will be great. many.
    When we think about what will catalyze this market, you can find two most important issues left: scalability and fiat currency debris.
    The reason scalability is indeed important is that without scalability, these applications are neither fast, cheap, nor simple to use. It’s easy to see Bitcoin now and state, “Digital currency provides only experienced an extremely limited development in ten years-this won’t scale!” I believe that is short-sighted, for many reasons. You are that Bitcoin is mainly used to transfer value, and you can find better options (such as for example Lightning). Furthermore, a scalable wise contract platform that is not used for payment has only already been developed for just three years.
    For example, Ethereum only took about three years. Although the previous few yrs have been spent on enhancing the developer’s expertise (UX), bug fixes, etc., another three years will focus on scalable technology. Furthermore, until recently there have been no programs or projects running on Ethereum. From the practical viewpoint, until you can find real applications, folks who are involved in scalability can watch these actual make use of cases to review how to solve the development problem.
    You can find two places where the blockchain can be expanded: layer 1 and layer 2. We shall analyze it below.
    The initial layer is merely the underlying blockchain, such as for example Ethereum and Bitcoin. The primary scalability difficulties boil down to system, storage and computing power. The system is the greatest bottleneck. If you want to spread a stop full of information all over the world, you can send out it to many computers, and these computer systems will deliver it to many other computers, etc, until the entire system has obtained these information blocks. . This takes a lot of period, which is why Ethereum and Bitcoin have a relatively very long time between blocks. When you can figure out how to reduce the propagation period and reduce the period required to deliver blocks for the system, you can increase throughput and rate. Even if your personal computer will be 10 times more powerful than the current computer, the problem of system transmission still can’t be solved. Since bandwidth continues to be the limiting aspect, throughput will not change or increase much.
    Some ideas for solving network problems include compressing data in order that nodes only send smaller amounts of data. Another method is to try to reduce the amount of hops required for the entire system to receive a data stop by building an identical content delivery system (CDN) at the blockchain. This is exactly what the Bloxroute project is doing. This will result in a significant 100-fold increase in throughput.
    Another attempt would be to not require every computer for the network to know every transaction, or even to effectively “breakdown” things. I will discuss sharding and STARKS (another technical solution) separately, because they essentially solve all three barriers to scalability during execution. There are also direct acyclic graphs (DAG), which allow people to procedure and broadcast dealings in parallel, which might help solve system problems. The challenge is that no-one knows how to implement global transaction sorting in DAG. Having less transaction sorting features makes dealings and financial programs very difficult.
    The following methods may also be implemented: separate processing transactions from consensus, or use both quick and slow paths in a relatively centralized network by default, but if problems occur, return to a completely decentralized approach. That is also another great and unique attempt that can increase throughput by 100 instances or more.
    Storage and computing power
    Two other major challenges are storage and computing energy. Computing power is simpler, it is almost always increasing, and even my MacBookPro is capable of doing thousands of dealings per 2nd. If you want to improve it further, we can do a lot of work by switching to using Web Assembly. Web Set up is even more optimized than EVM and will be carried out as native code, while EVM is fairly slow. Additionally it is possible to procedure noninteractive dealings in parallel through multiple processor cores/threads.
    You can find two problems with storage. You are that today’s blockchain requires a lot of read and create operations. This is solved by parallelization-Ethereum has recently started achieving this work.
    Another problem is the massive amount storage generated by the storage blockchain and the data related to the blockchain. Bitcoin and Ethereum require a huge selection of gigabytes of storage space, and one day time this will achieve tens of thousands of megabytes. One solution to this is to use some devices to near blocks at certain points, enabling nodes to take off the history and shop only updated blocks. Nevertheless, it is still essential to shop all state information related to the blockchain, and additional research on how to shop data better, compress, and make use of less data are all very important subjects.
    You can find two technologies that can solve all of the scalability issues of the first layer: fragmentation and STARKS. Sharding and STARK are both promising. In my opinion, the two remain about three yrs away from mass production and make use of.
    Fragmentation implies that each node within the network doesn’t need to shop all data, procedure all transactions, and even broadcast all blocks. A straightforward way to understand it is, assume you want to slice the blockchain into n pieces, and users only need to pay attention to the area of the slice they make use of.
    Of course, security concerns will arise: how will you ensure that shards can’t be attacked, how to approach invalid transactions, and how to review certain content? There are difficulties in achieving conversation between shards. For example, suppose an Augur marketplace is distributed on shard “A” and Dai will be distributed on shard “B”: it is necessary to communicate safely with one another in order for Augur to use Maker. Let’s assume that all the difficulties listed above are solved, including the problem of ensuring that data does not vanish through sharding (information availability), you’ll eventually get a scalable remedy that solves system problems, computing troubles, and storage difficulties.
    For STARKS, the theory is that you can bundle a bunch of dealings collectively and prove the fact that dealings are processed in a reliable way, and the node only verifies the data. So one day you can procedure 10,000 dealings by verifying an individual piece of proof. Of course, the Stark remedy has issues just like the dimension of proof and creation period, but companies like Starkware are solving these issues. Less computing energy and system bandwidth are needed because the technology enables people to verify batch dealings instead of verifying each transaction.
    The second layer involves the protocol and technology stack, including the following systems
  • Status/payment channel
  • Side chain
  • Plasma (instance: Gluon Plasma and Arbitrum)
    All these systems support smart contracts and do not have certain restrictions of scalability, and each system has various trade-offs.
    For the state channel, capital is used to home loan the contract, and the transaction information is signed to transfer the funds. The trade-off for this will be liquidity/capital lock-in, and the collateral reaches least twice the transaction volume, so this technology is suitable for use situations such as payment.
