Banks and Blockchain Transactions – Which Is Better?

Many cryptocurrency critics believe that blockchain transactions are far too slow to be ever applicable for mass adoption within banking and financial institutions, failing to understand blockchain and cryptocurrency technology is still in its infancy.  In this post, we’re going to look at the pros and cons of each system and explore the future of payment systems.

Banks and payment systems look in some ways more efficient than blockchain transactions, but in many cases, they’re actually more involved. In fact, as soon as they’re being used to make cross-border payments and settlements, they start to reveal some flaws. They, too, can become slow, expensive, or worse – they can lock people out through no fault of their own, and for no apparent reason.

Bank-to-bank transactions through SWIFT network take three to five working days to reach its destination, which is extremely slow by cryptocurrency standards. In contrast, an average person with no connection to a bank or money transfer service can securely send and receive Bitcoin anywhere around the world with just a smartphone and a stable Internet connection in as short as ten to fifteen minutes without the risk of being censored out by the system.

Wire transfers cost somewhere between $10 to $30, plus 6% spread on foreign exchanges. In other words, if you’re sending $5,000 from Australia to Canada, you’ll pay as much as $330 on that single transaction. This doesn’t account for differences in rates from country to country (fees for sending money from US to Africa can be as high as 15%).

Bitcoin’s transaction fees peak at around $55 in December 2017 during a massive buying spree. But most of the time, sending Bitcoin to someone anywhere around the world will only cost a fraction of a dollar, to as high as $10 depending on priority and network load. And since it’s considered a borderless, global currency, users can forget about foreign exchange rates.

Companies like Abra have been using Bitcoin as a cheaper alternative to international settlement systems. Interestingly, certain banks like the ones in the Philippines allow remittances using Bitcoin, and recipients can take their pesos straight out of the ATM without an ATM card or a bank account.

Within the cryptocurrency ecosystem, on-chain and off-chain implementations can have a significant impact both on energy consumption and transaction throughputs. As a general rule, the more it shifts toward decentralization, the more challenges it needs to deal with scaling; but as more features become centralized, the more scalable it becomes. How these challenges will be overcome in the next couple of decades is anybody’s guess.

Some of the proposed on-chain solutions is the move towards proof-of-stake consensus algorithm (e.g., Ethereum Casper), and delegated proof-of-stake (e.g. EOS and Cardano). Off-chain solution include Lightning Network (e.g. Bitcoin), and side-chains. Improving the blockchain’s inner workings not only helps with efficiency, but also makes energy consumption more manageable.

 

Conclusion

Cryptocurrency might not be as nimble as people would expect from banks when it comes to local micro-transactions. However, we’ve seen some progress lately, with SegWit adoption being used in 40% of all Bitcoin transactions, enabling shorter confirmation times, significantly lower fees, and Lightning Network integration. Users can start experimenting with Lightning wallets in their beta version (Eclair, Zap, RawTX, etc.), and buy small stuff from online stores like the ones made by Blockstream specifically for that purpose.

Cryptocurrency will only get better as time goes by, and we’ve already seen some progress from greener solutions, to mining hardware, and software development. There’s no limit to the number of ways cryptocurrency can solve many of its challenges. All it takes is an open mind and a little bit of creativity.

 

The Top Cryptocurrency and Blockchain Projects in 2018

There’s been a change in the outlook for cryptocurrency during the past few months. People seldom talk about the markets or the price of Bitcoin. Volatility has been causing a lot of uncertainty, and mainstream adoption came to a virtual standstill.

Nonetheless, the cryptocurrency space showed remarkable resilience as blockchain projects continue to expand its borders with more lateral thinking and “out-of-the-box” blockchain solutions. We’ll explore some of their use-cases and find out whether these currencies and platforms are the next big thing.

 

Why People Invest in These Projects

Despite the recent lull in cryptocurrency trading and mining, blockchain projects and ICOs are very much in the business for 2018. Investors and tech companies remain optimistic about the future of the cryptocurrency space amidst tightening restrictions and negativity. In fact, according to Coindesk, the amount of money raised in ICOs in the first quarter alone exceeded the total amount last year.

Most ICOs and blockchain projects didn’t end up well for a lot of investors (more than 90% failed to deliver). However, there are a few examples like Binance and EOS which turned out as good investments. Binance became one of the leading cryptocurrency exchanges with a BNB market cap of over $1 billion – the second most valuable token on Coinmarketcap. EOS, on the other hand had a successful, albeit controversial mainnet launch, and is now a full-fledged decentralized application platform second only to Ethereum.

Smart investors consider the current state of affairs as a golden opportunity to hunt for new projects with the greatest potential, particularly in their early stages when they are mostly undervalued. Investing early on has the advantage of maximum gains with the least amount of exposure. For instance, a hundred dollars’ worth of investments at ten cents per token won’t break the bank if things go south. But if it turns out to be a real investment, gains will be exponential (e.g., BNB and EOS tokens are worth a hundred times more than their initial price in 2017)

 

 

Blockchain Projects to Watch for in 2018

Finding a good investment can be a real challenge since we’re dealing with dozens of new blockchain projects and ICOs every month. If you’re lucky enough, you might be able to land on some big winners from a list of projects. But before anything else, please bear in mind that this is not investment advice, and you are solely responsible for any gains or losses. That said, here are five of the most talked-about blockchain projects in 2018.

 

Zilliqa (ZIL). Launched in January, the project puts a lot of work in building a highly scalable decentralized platform using a method known as “sharding.” Unlike in Bitcoin, each node will be working in parallel within a group of nodes called “shard,” verifying a subset of all the transactions occurring at the same time (also called parallel processing). Sharding works perfectly in many centralized systems (Ultima Online, Google, etc.). However, it presents an immense technical challenge when applied on a decentralized environment. Ethereum has been working hard on it as part of its on-chain scaling solution in hopes of solving the security/scalability/decentralization trilemma. Zilliqa’s entry into the whole sharding scene threatens to steal the thunder from Ethereum by becoming the first to come up with a workable solution. Some estimates it to be around January 2019. Key features include:

  • faster transaction throughputs (speed improves as the network grows)
  • employs practical Byzantine Fault Tolerance as a consensus mechanism
  • reduced energy consumption (mining is spaced a hundred blocks apart)
  • maintains a decentralized network structure (a new shard is created for every 600 nodes)

Basic Attention Token (BAT). Cutting the middleman goes beyond peer-to-peer transactions to include decentralized, blockchain-based digital advertising in the form of an open-source, ad-free browser with its own currency. Brave Browser is one of today’s hottest Internet browsing software because it allows users to block ads and trackers completely free. In fact, as many as 3 million people have already been using Brave, becoming one of Google Play’s top ten in the Android browser category. The project is moving towards the creation a decentralized advertising platform using its own currency – Basic Attention Token – to incentivize both content creation and user attention. It works in some ways like Google Ads but in a more transparent and decentralized manner. The key advantages of BAT from an investor’s point of view include:

  • good potential for adoption (sold out BAT worth $35 million in 30 seconds)
  • strong support from the community (Brave browsing experience receive a lot of positive feedback from users)
  • a solid team of experienced developers (founded by no less than the co-founder of Mozilla, Firefox, and creator of JavaScript)

Kin (KIN). Canadian messaging app company Kik Interactive is making headway into cryptocurrency adoption with the launching of Kinecosystem. The company hopes to build a community of users and developers sharing resources, and making digital goods and services. However, unlike most blockchain startups with no real users, Kin’s integration into the Kik Messenger meant its value could potentially rise with over 300 million active users.  The company is now moving towards the next phase, inviting all developers and content creators in building the ecosystem for large KIN payouts. Gains will take time, but you might want to consider its advantages, namely:

  • KIN’s practical use-case as a digital currency on an existing application (Kik has been in use since 2010)
  • user base is mostly made up of digital-natives (teens, millennials, and active mobile users)
  • Kik’s emphasis on anonymity

DeepBrain Chain (DBC). Blockchain companies like DeepBrain Chain sees decentralization as the future of the AI industry. Development of AI applications use up a huge amount of computing power. DeepBrain Chain works by utilizing computational resources across millions of nodes on the neural network in building AI applications which are then published onto the blockchain. Nodes that successfully deploy mirror images will receive payouts in DBC. It plans on migrating out of NEO to its own mainnet in Q4, with its own consensus algorithm (proof of importance and delegated proof of stake). The goal is to become the deep learning machine for the AI industry. Successful adoption is achievable through:

  • growth in people’s interest in the AI industry
  • reduced computational cost of AI companies through resource-sharing
  • secure, decentralized method of storing AI information.

Wormhole. Bitcoin Cash might soon be able to run smart contracts through its proposed protocol layer known as Wormhole. Developers plan on forking the Omni Layer to create a platform for smart contracts on top of Bitcoin Cash. Much of it is still in the works as of this moment, but news is, they’re going to issue a token named “Wormhole Cash.” Investors and crypto-enthusiasts are keeping track of its progress since it is expected to have a very high demand upon release.

 

Conclusion

The cryptocurrency space has been constantly evolving even as the noise and the hype surrounding cryptocurrency have mostly faded. Cryptocurrency is here to stay, and we’ll be seeing more projects in the near future that will bridge the gap between the average user and blockchain technology.

Facebook’s Update on Crypto-related Ads – Why Should It Matter?

Facebook hit the news when it back peddled on its decision to ban cryptocurrency ads outright from the social media platform. This has now made technology companies, cryptocurrency and blockchain communities optimistic this move will set off a precedent for other advertisers to follow, particularly Google and Twitter, who earlier warned of a similar ban on cryptocurrency ads.

What are the implications of Facebook’s reversing its view on cryptocurrency, and what are we to expect about the future of blockchain technology?

 

What Changed After the Update?

Facebook now accepts cryptocurrency ads, but only from pre-approved advertisers who filed their cryptocurrency products and services onboarding request. ICOs and promotions associated with deceptive high-yield investment programs are still banned from advertising.

The update took effect after a six-month hiatus in cryptocurrency ads on Facebook. Apparently, the tech giant have found compelling reasons for reversing some of its decision after being dismissive on anything crypto-related. (uhhh… money of course!) There are also some rumblings Facebook plans on stepping into the cryptocurrency space with their own initial coin offering.

So far, legitimate cryptocurrency businesses like Cointelegraph.com have not been able to boost their posts a day after the ban was lifted. It’s very likely that Facebook is implementing more stringent rules and are, indeed, checking on the advertiser’s credentials with painstaking effort. We’ll learn more about the specific details of the screening process as they unfold.

 

Not a Complete Turnabout

Facebook didn’t go all the way, and instead chose to “loosen” some its policy on cryptocurrency advertising. A recent post from the product management director indicates an eligibility check, which takes into account licenses and pertinent documents submitted by each applicant. Facebook wants to avoid another Bitconnect incident or turn it a breeding ground for ICO scams (70% of advertised ICOs failed to materialize).

There’s no guarantee that every cryptocurrency and blockchain businesses would receive their stamp of approval. The least they can do for now is hope they don’t get screened out or send the wrong signal to the management and mistake them for ICOs or HYIPs. Facebook is open to the idea of revising this policy as they see fit and encourages everyone to give their feedback.

 

More KYCs and Background Checks on Advertisers

All advertisers in cryptocurrency must be “pre-approved” before posting ads on Facebook. To do so, they have to disclose information about their company such as:

 

  • purpose and nature of their business
  • Facebook ad account ID
  • website domain
  • licenses and credentials
  • company name
  • business address

You can apply for your pre-approval HERE

 

 

 

 

 

 

Facebook, basically, performs due diligence on advertisers on behalf of its users, which is a good thing for cryptocurrency. Done right, this might actually boost investor confidence. With stricter regulation in place, Facebook hopes to open more opportunities which could further mass adoption for cryptocurrency, and significantly increase ad revenue to the company.

Meanwhile, cryptocurrency and ICO scams might have a hard time after the update, but that doesn’t necessarily mean Facebook won’t have any of those. In fact several cryptocurrency and ICO scams were still able to get through, ironically, even after the ban on cryptocurrency ads.

 

What Changed Their Mind?

Facebook wasn’t so clear about the reason for partially lifting the ban on crypto-related ads. People have their own views and offer some explanation as to why this is the case.

Missing Out On Revenue. At times, Facebook is more worried about optics then revenue. This isn’t necessarily a bad thing but when it comes to crypto, Facebook has constantly missed the boat. This is evident when Facebook took a massive hit in market value recently. One of the main reasons for the price dip is the lack of awareness in its underlying technology; censoring out everything crypto-related from their platform could only serve to aggravate the situation. By encouraging users to learn more about the cryptocurrency through ads and meaningful social interaction, they might as well rack up huge profits along the way.

Facebook’s Launching Its Exploratory Blockchain Group. For a tech company this huge, it’s not difficult to imagine Facebook having its own native currency in the near future. Their announcement about the launching of an exploratory blockchain group has led to some rumours about their future involvement in the cryptocurrency space. If true, then this could mean adoption on a massive scale with its two billion plus users worldwide.

 

Conclusion

Facebook’s decision to lift the ban on crypto-related ads is a statement on cryptocurrency’s future utility as a store of value, or even as a medium of exchange. There’s no denying that cryptocurrency and blockchain technology has become a major force in shaping our current financial system. They might, as well, be a part of it instead of closing doors on an opportunity which could probably give them a decisive edge along the way.

How You Should Look At Cryptocurrencies When It Comes To Your Financial Goals

Cryptocurrency can have a lot of potential as an investment if you have an informed and disciplined approach. You could invest in the long term, or as a one-time goal. Whatever the reason for investing in cryptocurrency, you should always have the reason why you’re investment top of mind. Maybe it’s a holiday tour in Europe, a luxury cruise in the Caribbean, or perhaps that amazing sports car, or home theatre system you’ve always wanted.

Perhaps you want to start out your own business when you retire, or create multiple streams of income with your cryptocurrency investments. Whatever your reason why is, cryptocurrency seems to be a very promising investment proposition. Your “why” will help you stay focused and committed to the task at hand. If you stay connected to your goals, you’re less likely sell because of panic or over-extend yourself.

The Internet has no shortage of success stories about Bitcoin, from the legendary pizza shop in UK selling two boxes of pizza for 10,000 BTC, the college dropout from Brooklyn who made the first dedicated ASIC miner, the teenage-school-boy-turned-Bitcoin investor from Idaho, to the Bitcoin millionaires and entrepreneurs the likes of Jered Kenna, and the Winklevoss Twins. But don’t pay attention to the hype. You’re not likely to become an overnight success story. You’ll have to do your homework and make smart decisions, otherwise you’ll run the risk of losing out big.

 

It’s Never Too Late

When talking about investing in cryptocurrencies at this point in time, people often speak of “missing the boat.”

“Bitcoin went insanely high in 2017, and I missed the boat.”

“If only I have bought Bitcoin and Ethereum back when they’re still pretty cheap. Now, it’s too late.”

Truth is, cryptocurrency is a relatively young industry. It entered the scene in 2009 and it’s continuously growing and improving for the last nine years. Sir Richard Branson is only one among many influencers who believe there might be currencies in the future that would match or even surpass Bitcoin as a digital asset and as a medium of exchange.

Just think back to the beginnings of Myspace. A lot of investors thought it was too late to invest in or create a new social media because Myspace was dominating the internet. Now Facebook is dominating and looks to rain supreme in the foreseeable future.

Vitalik Buterin proved cryptocurrency can be more than just a medium of exchange when he created the first platform and currency with a programmable blockchain – Ethereum.

Soon, Bitcoin will be more accessible to millions of everyday users, commercial establishments, and businesses worldwide through a second layer, known as the Lightning Network, which could render transaction speeds ten times or even a hundred times faster.

These are cryptocurrency’s first wobbly steps in creating a better way to transact and store value in a completely decentralized financial system.

In comparison, many of our industries today are decades-old and have already produced some of the world’s technological breakthroughs; things we often take for granted like the cars we drive at work, the phones we take our pictures with, or the Internet we use every single day.

These industries just keep getting better with each passing year. The automotive industry didn’t stop with Ford’s “Model T” or Mercedes-Benz’s “Motorwagen”; today we have hybrid, electronic and self-driving prototypes by Tesla and Google.

The Internet didn’t stop with email, TCP/IP and packet-switching; now, there’s Worldwide Web, HTTPS, cloud computing, streaming media, free Internet calls, video conferencing, mobile apps, and a host of other features people thought were not possible with the Internet (back then, it took several hours to upload/download a single jpeg image).

And let’s not forget our mobile phones which started out as clunky, metal-and-plastic bricks with large keypads and small monochrome backlit screens. Today, we have Apple and Android Phones which crosses between mobiles phones and mini-computers with HD cameras, internet and browsing capability.

People still invest in these technologies despite some of them being half a centuries-old. Cryptocurrency isn’t even half as old as many of our industries. Much of our cryptocurrency and blockchain space is uncharted territory, waiting to be explored, and harnessed to its full potential.

So, is it too late to invest in cryptocurrencies? Of course, not. In fact, we’re just getting started.

 

Knowing Your Investment Goal

Generally, we want to invest our discretionary income (disposable income minus living expenses) into something we want to enjoy much later. It’s the kind of money we can part with or set aside, and won’t have any hard feelings if everything goes south.

We don’t want to use money we pay our bills and mortgages, or buy groceries with. Or, heaven forbid, owe huge sums of money from banks at interest just to buy cryptocurrencies and ICOs. More often than not, this attitude of chasing the hype and FOMO will get people crushed.

People often invest in cryptocurrencies as a retirement option. This is not a good idea. Cryptocurrencies are highly volatile and should not be relied upon to retire with.  A safe and conservative approach is to set a small amount of discretionary income, say fifty to a hundred dollars a month, (depending on your income) to buy Bitcoin and other large-cap currencies – also known as dollar-cost averaging. Investors stick with that amount regardless of how often or how much the markets turn. It’s like a savings account, in a way, but in cryptocurrency.

Some people don’t wait for retirement and want to get out as soon as they have the opportunity. They want to store up some money as an employee so they can start out on their own. Maybe a small business, an S-corp, or an LLC. And what better way to grow capital than to invest?

Cryptocurrency exchanges are a good place to start when studying markets that would potentially grow in value. You can take short courses in financial literacy on how to invest in stocks and apply those concepts in cryptocurrencies such as asset allocation and portfolio management. Or, you can take it to the next level by learning some codes and understanding how cryptocurrencies work under the hood.

Some investors become full-time cryptocurrency traders and investors over time. These are usually angel investors, and venture capitalists – people who make risky financial decisions in order to make a lot of money. Returns can vary widely from zero to ten times the initial capital. Investment options include ICOs and new or emerging cryptocurrencies. The goal is to maximize returns while minimizing risk exposure.

Other reasons for investing in cryptocurrencies is simply to gain first-hand experience. Few people were lucky enough to have hit the jackpot, or bought in just before the big breakout out of sheer luck. However, these are just rare occurrences, and we need to be aware of “survivor bias” when it comes to personal stories and testimonials about people who got rich trading or investing in cryptocurrencies. Most people hear about 1% of the population who actually made it, but forget the 99% who failed.

 

A Smart Way to Invest

Your investment capital will depend on your age, income, priorities, and investment goals. Tax laws can also impact your ROI. You can check the legal status of cryptocurrency in your country from Coin.dance’s site (https://coin.dance/poli), or seek competent legal advice about the possible implications of investing in cryptocurrencies.

That said, here’s a sample of how you might want to structure your cryptocurrency investment. Let’s look at it from the perspective of a middle-class employee earning a net income of $3,500 a month.

The first step is to subtract the living expenses from the net income. What you’re left with is your discretionary income which you can freely use to plan for your future or hedge against financial losses. (Note: Do not invest all of your discretionary income. You should put it aside for entertainment, holidays, emergencies, and donations to good causes.)

 

$ 3,500.00               net/disposable income (after-tax)

2,500.00                    living expenses


= $ 1,000.00               discretionary income

 

Another option is to have multiple income streams, or side jobs aside from your typical 9-5. From here we’ll set up an account and possibly allocate our resources, thus:

20% emergency account
40% freedom/savings account
30% capital investment
10% trading/speculating

 

Here is a good way to look at our income. The first two (emergency and freedom/savings) are considered a necessity because of the fact that life is unpredictable. Anything can happen, so it’s always best to prepare for the unexpected. Remember Murphy’s Law: “If something can go wrong, it probably will.”

Your emergency and freedom account act as your “safety net” against life’s unpleasant surprises. An emergency account is used to cover your expenses like medical bills, repairs, etc. Others may spend them on health, car, and home insurances, which is also a viable option.

Freedom/savings account will cover your living expenses for six to twelve months in case you get laid off or choose to leave the company (some companies may offer a severance package, but not always).

The last two (capital investment and trading/speculating) is where you make crucial financial decisions that could potentially change your life or move yourself upward in today’s economy. You can have a choice between entrepreneurship and becoming a full-time trader/investor.

Being an entrepreneur gives you greater control over your finances. In the context of a cryptocurrency or blockchain-based business, you could run a cloud mining rental service, pool mining website, or cryptocurrency exchange. Once your company gains traction, you can start growing your business by raising capital through crowd-sales (check the legal status of ICOs in your country). Some start-ups may go with crowd-sales straightaway.

You can become a full-time cryptocurrency trader and invest heavily in cryptocurrencies where you’re constantly on the lookout for trading and investing opportunities, such as breakouts, funding blockchain start-ups, and ICOs. Beginners are often discouraged from getting involved in cryptocurrency trading and investing particularly those with very little or no background in dealing with financial markets. We don’t recommend this option unless you have an entire backup plan. Full-time cryptocurrency traders should have millions of dollars in fiat currency just in case they lose everything.

Some look at investing as the polar opposite of entrepreneurship, requiring a different strategy and mental disposition. For one thing, investing is market-dependent and may not necessarily have a steady cash flow, whereas in an entrepreneurship, cash flow is the difference between growth and going out of business.

Finally, the last 10% of your investment might be used for trading in a speculative market, particularly new, or small to medium cap currencies, tokens, and altcoins. Bitcoin and Ethereum are worth less than a dollar at launch; today, they’re valued by the hundreds and thousands. Although we can’t compare them with new, emerging currencies, we can’t discount the possibility of such a currency taking the same path in the near future (think EOS, Monero, and Dash)

What’s Next? Pushing the Boundaries of Blockchain Technology

Cryptocurrency could be running on a “different” blockchain, far better than its predecessors. Ethereum, became the first to have a “programmable” blockchain which made the currency in a class of its own. Today, we are entering into a new era of blockchain technology which promises scalability, interoperability, and sustainability with a first-of-its-kind third generation decentralized currency, Cardano.

We’ll explore the possibilities as well as the challenges in this new development in blockchain technology – what can it do to solve the prevailing issue of scalability and how far can it push the boundaries.

 

Blockchain Scaling and Its Challenges

Blockchain redefined the meaning of currency as a “trust-less” and “decentralized” medium of exchange allowing people to exchange value on a peer-to-peer network without a third party. It also solved the problem of double spending and fraud when dealing with digital assets in a virtual space with the combined strength of cryptographic functions and distributed consensus. But having such a high level of security also comes at the expense of speed and computing power.

Blockchain is difficult to scale because the exponential growth of the ever-increasing size, the necessary bandwidth to update all the ledgers across the network, and the proof of work algorithm which is self-limiting in terms of the number of transactions it can accommodate at a given time.

Some of the proposed solutions are, to take mining out of the picture, and use an alternative method of confirmation such as proof of stake and consensus protocol. Unfortunately, any attempt to improve scalability which takes mining and proof of work out of the way also tends to become convoluted and unsecure. There seems there is no way to create a blockchain that is both scalable, secure, and decentralized without losing some of its properties, one way or the other, or, writing a blockchain protocol from the ground up using an entirely different programming language.

Tinkering with the block size could only worsen the situation as bigger blocks would increase the blockchain size exponentially, thus consuming more bandwith and slowing down the network even more. The Bitcoin Cash hard fork of August 2017 attempts to solve Bitcoin’s scalability problem by following this route. However, it is doubtful that such measure could sustain the impact of mass adoption.

Some developers are now taking a different approach in their efforts to make a scalable, interoperable (communicates with other blockchains), and sustainable blockchain.

 

Making Blockchain a Lot “Smarter”

The simplicity of Bitcoin’s algorithm proved to be its greatest strength in terms of security. It is less prone to have errors and is more secure compared to other complex systems. Consequently, this would also mean less room for innovation within the blockchain itself (scripting used in Bitcoin is not “Turing-complete”). Moreover, developers couldn’t make drastic changes to the code without causing a fork in the blockchain. In such a case, the best scalability solution is to have a second layer for micro-transactions which “clears” each time these bundled transactions are broadcasted as one to the first layer, i.e. the blockchain. This is the idea behind Lightning Network.

However, to make this work, it should remain “trust-less,” secure, and shouldn’t involve a third party by adding a set of rules on top of the Bitcoin network to ensure that every transaction between two parties is settled upon meeting the conditions, or they can be rolled back if one of them refused to cooperate. Some of these rules include opening and pre-funding off-chain payment channels (or side-chains), “time-locks,” and having a “refund addresses” in case it fails to execute the agreement.

Ethereum accomplished the task with the idea of a “smart contract” between two or more people. After mining, the contract comes into force and becomes an immutable part of the blockchain. It uses a proprietary programming language (Solidity) which is more flexible than the script used by Bitcoin, and is primarily used for ICOs to fund projects and issue tokens to contributors. Some developers can make some interesting use of smart contracts such as the popular online blockchain game, Cryptokitties, where people can buy, sell, or breed virtual kittens on the Ethereum blockchain for profit.

Ethereum is regarded by developers as the second generation of blockchain technology for making such remarkable achievement. Blockchain technology is no longer just a method of making secure payments and storing value like Bitcoin, but also a more secure way of creating immutable, automated contracts without requiring a mediator in a physical sense. This opens up a world of possibilities for blockchain as a versatile platform for business and everyday use.

 

 

The Third Generation of Blockchain Technology

Cardano is considered by some as the third generation of blockchain technology for several reasons. First of all, it has a blockchain built with scalability in mind and uses a programming language known only to a few developers (Haskell and Plutus). Unlike the programming languages used in second generation blockchain which goes through a number loops and procedures one string at a time, it deals with the process of creating smart contracts and verification using a functional language which is more efficient. In other words, instead of commands, it uses mathematical formulas, i.e. functions.

An Ethereum smart contract, for instance, can go through a hundred iterations and procedures before coming up with a single output. This results in higher computational cost and could easily overload the network without some sort of regulatory mechanism that limits the number of loops or strings on a given contract. Ethereum came up with the idea of “gas”, which is the equivalent of mining fees for Bitcoin. This way, users cannot arbitrarily overload the network with excessive number of iterations. However, like Bitcoin, it also brings up the issue of scalability, computational cost, and sustainability

Cardano seeks to address this problem by revising the way blockchains should work. However, nothing is set in stone as of the moment and we couldn’t know for certain whether such proposal will have enough support from developers and the cryptocurrency community. Haskell and Plutus programming language is not so popular but can be extremely useful when applied to blockchains because it offers more flexibility.

There’s also a learning curve, should developers choose to support Cardano’s vision of a scalable blockchain, and it would have to compete with the developers’ attention who are fully engrossed in perfecting Lightning Network for Bitcoin, and the proof of stake scalability solution for Ethereum. One possible scenario is that all three of them will come to fruition about the same time, and by then we would have three or more fully scalable currencies which use different methods in achieving the same goal. Or, we may come up with just one solution that would annihilate other currencies and become the gold standard of future blockchain-based currencies. Could it be Cardano, Ethereum’s updated proof of stake version, or Bitcoin running on Lightning Network? The world watches as the story continues to unfold.
