Is The New Blockchain Internet The Web 3.0?
What is Blockchain Technology? A Step-by-Step Guide For Beginners
The blockchain is an undeniably ingenious invention – the brainchild of a person or group of people known by the pseudonym, Satoshi Nakamoto. But since then, it has evolved into something greater, and the main question every single person is asking is: What is Blockchain?
Is Blockchain Technology the New Internet?
By allowing digital information to be distributed but not copied, blockchain technology created the backbone of a new type of internet. Originally devised for the digital currency, Bitcoin blockchain, (Buy Bitcoin) the tech community has now found other potential uses for the technology.
In this guide, we are going to explain to you what the blockchain technology is, and what its properties are what make it so unique. So, we hope you enjoy this, What Is Blockchain Guide. And if you already know what blockchain is and want to become a blockchain developer please check out our in-depth blockchain tutorial and create your very first blockchain.
A blockchain is, in the simplest of terms, a time-stamped series of immutable records of data that is managed by a cluster of computers not owned by any single entity. Each of these blocks of data (i.e. block) is secured and bound to each other using cryptographic principles (i.e. chain).
So, what is so special about it and why are we saying that it has industry-disrupting capabilities?
The blockchain network has no central authority — it is the very definition of a democratized system. Since it is a shared and immutable ledger, the information in it is open for anyone and everyone to see. Hence, anything that is built on the blockchain is by its very nature transparent and everyone involved is accountable for their actions.
What exactly is Blockchain?
A blockchain carries no transaction cost.
(An infrastructure cost yes, but no transaction cost.) The blockchain is a simple yet ingenious way of passing information from A to B in a fully automated and safe manner. One party to a transaction initiates the process by creating a block. This block is verified by thousands, perhaps millions of computers distributed around the net. The verified block is added to a chain, which is stored across the net, creating not just a unique record, but a unique record with a unique history. Falsifying a single record would mean falsifying the entire chain in millions of instances. That is virtually impossible. Bitcoin uses this model for monetary transactions, but it can be deployed in many other ways.
Think of a railway company. We buy tickets on an app or the web. The credit card company takes a cut for processing the transaction. Blockchains, not only can the railway operator save on credit card processing fees, it can move the entire ticketing process to the blockchain. The two parties in the transaction are the railway company and the passenger. The ticket is a block, which will be added to a ticket blockchain. Just as a monetary transaction on the blockchain is a unique, independently verifiable and unfalsifiable record (like Bitcoin), so can your ticket be. Incidentally, the final ticket blockchain is also a record of all transactions for, say, a certain train route, or even the entire train network, comprising every ticket ever sold, every journey ever taken.
But the key here is this: it’s free. Not only can the blockchain transfer and store money, but it can also replace all processes and business models that rely on charging a small fee for a transaction. Or any other transaction between two parties.
Here is another example. The gig economy hub Fivver charges 0.5 dollars on a 5 transaction between individuals buying and selling services. Using blockchain the transaction is free. Ergo, Fivver will cease to exist. So will auction houses and any other business entity based on the market-maker principle.
Even recent entrants like Uber and Airbnb are threatened by blockchain . All you need to do is encode the transactional information for a car ride or an overnight stay, and again you have a perfectly safe way that disrupts the business model of the companies which have just begun to challenge the traditional economy. We are not just cutting out the fee-processing middle man, we are also eliminating the need for the match-making platform.
Because blockchain transactions are free, you can charge minuscule amounts, say 1/100 of a cent for a video view or article read. Why should I pay The Economist or National Geographic an annual subscription fee if I can pay per article on Facebook or my favorite chat app? Again, remember that blockchain transactions carry no transaction cost. You can charge for anything in any amount without worrying about third parties cutting into your profits.
Blockchain may make selling recorded music profitable again for artists by cutting out music companies and distributors like Apple or Spotify. The music you buy could even be encoded in the blockchain itself, making it a cloud archive for any song purchased. Because the amounts charged can be so small, subscription and streaming services will become irrelevant.
It goes further. Ebooks could be fitted with blockchain code. Instead of Amazon taking a cut, and the credit card company earning money on the sale, the books would circulate in encoded form and a successful blockchain transaction would transfer money to the author and unlock the book. Transfer ALL the money to the author, not just meager royalties. You could do this on a book review website like Goodreads, or on your own website. The marketplace Amazon is then unnecessary. Successful iterations could even include reviews and other third-party information about the book.
In the financial world the applications are more obvious and the revolutionary changes more imminent. Blockchains will change the way stock exchanges work, loans are bundled, and insurances contracted. They will eliminate bank accounts and practically all services offered by banks. Almost every financial institution will go bankrupt or be forced to change fundamentally, once the advantages of a safe ledger technology without transaction fees are widely understood and implemented. After all, the financial system is built on taking a small cut of your money for the privilege of facilitating a transaction. Bankers will become mere advisers, not gatekeepers of money. Stockbrokers will no longer be able to earn commissions and the buy/sell spread will disappear.
How Does a Blockchain Work?
Picture a spreadsheet that is duplicated thousands of times across a network of computers. Then imagine that this network is designed to regularly update this spreadsheet and you have a basic understanding of the blockchain.
Information held on a blockchain exists as a shared — and continually reconciled — database. This is a way of using the network that has obvious benefits. The blockchain database isn’t stored in any single location, meaning the records it keeps are truly public and easily verifiable. No centralized version of this information exists for a hacker to corrupt. Hosted by millions of computers simultaneously, its data is accessible to anyone on the internet.
To go in deeper with the Google spreadsheet analogy, I would like you to read this piece from a blockchain specialist.
“The traditional way of sharing documents with collaboration is to send a Microsoft Word document to another recipient and ask them to make revisions to it. The problem with that scenario is that you need to wait until receiving a return copy before you can see or make other changes because you are locked out of editing it until the other person is done with it. That’s how databases work today. Two owners can’t be messing with the same record at once. That’s how banks maintain money balances and transfers; they briefly lock access (or decrease the balance) while they make a transfer, then update the other side, then re-open access (or update again). With Google Docs (or Google Sheets), both parties have access to the same document at the same time, and the single version of that document is always visible to both of them. It is like a shared ledger, but it is a shared document. The distributed part comes into play when sharing involves a number of people.
Imagine the number of legal documents that should be used that way. Instead of passing them to each other, losing track of versions, and not being in sync with the other version, why can’t *all* business documents become shared instead of transferred back and forth? So many types of legal contracts would be ideal for that kind of workflow. You don’t need a blockchain to share documents, but the shared documents analogy is a powerful one.” – William Mougayar, Venture advisor, 4x entrepreneur, marketer, strategist, and blockchain specialist
The reason why the blockchain has gained so much admiration is that:
- It is not owned by a single entity, hence it is decentralized
- The data is cryptographically stored inside
- The blockchain is immutable, so no one can tamper with the data that is inside the blockchain
- The blockchain is transparent so one can track the data if they want to
The Three Pillars of Blockchain Technology
The three main properties of Blockchain Technology which have helped it gain widespread acclaim are as follows:
Pillar #1: Decentralization
Before Bitcoin and BitTorrent came along, we were more used to centralized services. The idea is very simple. You have a centralized entity that stored all the data and you’d have to interact solely with this entity to get whatever information you required.
Another example of a centralized system is the banks. They store all your money, and the only way that you can pay someone is by going through the bank.
The traditional client-server model is a perfect example of this:
When you google search for something, you send a query to the server who then gets back at you with the relevant information. That is a simple client-server.
Now, centralized systems have treated us well for many years, however, they have several vulnerabilities.
- Firstly, because they are centralized, all the data is stored in one spot. This makes them easy target spots for potential hackers.
- If the centralized system were to go through a software upgrade, it would halt the entire system
- What if the centralized entity somehow shuts down for whatever reason? That way nobody will be able to access the information that it possesses
- Worst case scenario, what if this entity gets corrupted and malicious? If that happens then all the data that is inside the blockchain will be compromised.
So, what happens if we just take this centralized entity away?
In a decentralized system, the information is not stored by one single entity. In fact, everyone in the network owns the information.
In a decentralized network, if you wanted to interact with your friend then you can do so directly without going through a third party. That was the main ideology behind Bitcoins. You and only you alone are in charge of your money. You can send your money to anyone you want without having to go through a bank.
Pillar #2: Transparency
One of the most interesting and misunderstood concepts in blockchain is “transparency.” Some people say that blockchain gives you privacy while some say that it is transparent. Why do you think that happens?
Well… a person’s identity is hidden via complex cryptography and represented only by their public address. So, if you were to look up a person’s transaction history, you will not see “Bob sent 1 BTC” instead you will see “1MF1bhsFLkBzzz9vpFYEmvwT2TbyCt7NZJ sent 1 BTC”.
The following snapshot of Ethereum transactions will show you what we mean:
So, while the person’s real identity is secure, you will still see all the transactions that were done by their public address. This level of transparency has never existed before within a financial system. It adds that extra, and much needed, level of accountability which is required by some of these biggest institutions.
Speaking purely from the point of view of cryptocurrency, if you know the public address of one of these big companies, you can simply pop it in an explorer and look at all the transactions that they have engaged in. This forces them to be honest, something that they have never had to deal with before.
However, that’s not the best use-case. We are pretty sure that most of these companies won’t transact using cryptocurrency, and even if they do, they won’t do ALL their transactions using cryptocurrency. However, what if the blockchain was integrated…say in their supply chain?
You can see why something like this can be very helpful for the finance industry right?
Pillar #3: Immutability
Immutability, in the context of the blockchain, means that once something has been entered into the blockchain, it cannot be tampered with.
Can you imagine how valuable this will be for financial institutes?
Imagine how many embezzlement cases can be nipped in the bud if people know that they can’t “work the books” and fiddle around with company accounts.
The reason why the blockchain gets this property is that of the cryptographic hash function.
In simple terms, hashing means taking an input string of any length and giving out an output of a fixed length. In the context of cryptocurrencies like bitcoin, the transactions are taken as input and run through a hashing algorithm (Bitcoin uses SHA-256) which gives an output of a fixed length.
Let’s see how the hashing process works. We are going to put in certain inputs. For this exercise, we are going to use the SHA-256 (Secure Hashing Algorithm 256).
As you can see, in the case of SHA-256, no matter how big or small your input is, the output will always have a fixed 256-bits length. This becomes critical when you are dealing with a huge amount of data and transactions. So basically, instead of remembering the input data which could be huge, you can just remember the hash and keep track.
A cryptographic hash function is a special class of hash functions that has various properties making it ideal for cryptography. There are certain properties that a cryptographic hash function needs to have in order to be considered secure. You can read about those in detail in our guide on hashing.
There is just one property that we want you to focus on today. It is called the “Avalanche Effect.”
What does that mean?
Even if you make a small change in your input, the changes that will be reflected in the hash will be huge. Let’s test it out using SHA-256:
Do you see that? Even though you just changed the case of the first alphabet of the input, look at how much that has affected the output hash. Now, let’s go back to our previous point when we were looking at blockchain architecture. What we said was:
The blockchain is a linked list that contains data and a hash pointer that points to its previous block, hence creating the chain. What is a hash pointer? A hash pointer is similar to a pointer, but instead of just containing the address of the previous block it also contains the hash of the data inside the previous block.
This one small tweak is what makes blockchains so amazingly reliable and trailblazing.
Imagine this for a second, a hacker attacks block 3 and tries to change the data. Because of the properties of hash functions, a slight change in data will change the hash drastically. This means that any slight changes made in block 3, will change the hash which is stored in block 2, now that in turn will change the data and the hash of block 2 which will result in changes in block 1 and so on and so forth. This will completely change the chain, which is impossible. This is exactly how blockchains attain immutability.
Maintaining the Blockchain – Network, and Nodes
The blockchain is maintained by a peer-to-peer network. The network is a collection of nodes that are interconnected to one another. Nodes are individual computers that take in input and performs a function on them and gives an output. The blockchain uses a special kind of network called “peer-to-peer network” which partitions its entire workload between participants, who are all equally privileged, called “peers”. There is no longer one central server, now there are several distributed and decentralized peers.
Why do people use the peer-to-peer network?
One of the main uses of the peer-to-peer network is file sharing, also called torrenting. If you are to use a client-server model for downloading, then it is usually extremely slow and entirely dependent on the health of the server. Plus, as we said, it is prone to censorship.
However, in a peer-to-peer system, there is no central authority, and hence if even one of the peers in the network goes out of the race, you still have more peers to download from. Plus, it is not subject to the idealistic standards of a central system, hence it is not prone to censorship.
If we were to compare the two:

The decentralized nature of a peer-to-peer system becomes critical as we move on to the next section. How critical? Well, the simple (at least on paper) idea of combining this peer-to-peer network with a payment system has completely revolutionized the finance industry by giving birth to cryptocurrency.
The use of networks and nodes in cryptocurrencies.
The peer-to-peer network structure in cryptocurrency is structured according to the consensus mechanism that they are utilizing. For cryptocurrency like Bitcoin and Ethereum which uses a normal proof-of-work consensus mechanism (Ethereum will eventually move on to Proof of Stake), all the nodes have the same privilege. The idea is to create an egalitarian network. The nodes are not given any special privileges, however, their functions and degree of participation may differ. There is no centralized server/entity, nor is there any hierarchy. It is a flat topology.
These decentralized cryptocurrencies are structured like that is because of a simple reason, to stay true to their philosophy. The idea is to have a currency system, where everyone is treated as an equal and there is no governing body, which can determine the value of the currency based on a whim. This is true for both bitcoin and Ethereum.
Now, if there is no central system, how would everyone in the system get to know that a certain transaction has happened? The network follows the gossip protocol. Think of how gossip spreads. Suppose Alice sent 3 ETH to Bob. The nodes nearest to her will get to know of this, and then they will tell the nodes closest to them, and then they will tell their neighbors, and this will keep on spreading out until everyone knows. Nodes are basically your nosy, annoying relatives.
So, what is a node in the context of Ethereum? A node is simply a computer that participates in the Ethereum network. This participation can be in three ways
- By keeping a shallow-copy of the blockchain aka a Light Client
- By keeping a full copy of the blockchain aka a Full Node
- By verifying the transactions aka Mining
However, the problem with this design is that it is not really that scalable. Which is why a lot of new generation cryptocurrencies adopt a leader-based consensus mechanism. In EOS, Cardano, Neo, etc. the nodes elect leader nodes or “supernodes” who are in charge of the consensus and overall network health. These cryptos are a lot faster but they are not the most decentralized of systems.
So, in a way, cryptos have to make the trade-off between speed and decentralization.
Who Will Use The Blockchain?
As a web infrastructure, you don’t need to know about the blockchain for it to be useful in your life.
Currently, finance offers the strongest use cases for the technology. International remittances, for instance. The World Bank estimates that over $430 billion US in money transfers were sent in 2015. And at the moment there is a high demand for blockchain developers.
The blockchain potentially cuts out the middleman for these types of transactions. Personal computing became accessible to the general public with the invention of the Graphical User Interface (GUI), which took the form of a “desktop”. Similarly, the most common GUI devised for the blockchain are the so-called “wallet” applications, which people use to buy things with Bitcoin, and store it along with other cryptocurrencies.
Transactions online are closely connected to the processes of identity verification. It is easy to imagine that wallet apps will transform in the coming years to include other types of identity management.
What is Blockchain good for?
The blockchain network gives internet users the ability to create value and authenticates digital information. What new business applications will result from this?
#1 Smart contracts
Distributed ledger technology enable the coding of simple contracts that will execute when specified conditions are met. Ethereum is an open-source blockchain project that was built specifically to realize this possibility. Still, in its early stages, Ethereum has the potential to leverage the usefulness of blockchains on a truly world-changing scale.
At the technology’s current level of development, smart contracts can be programmed to perform simple functions. For instance, a derivative could be paid out when a financial instrument meets a certain benchmark, with the use of blockchain technology and Bitcoin enabling the payout to be automated.
#2 The sharing economy
With companies like Uber and Airbnb flourishing, the sharing economy is already a proven success. Currently, however, users who want to hail a ride-sharing service have to rely on an intermediary like Uber. By enabling peer-to-peer payments, the blockchain opens the door to direct interaction between parties — a truly decentralized sharing economy results.
An early example, OpenBazaar uses the blockchain to create a peer-to-peer eBay. Download the app onto your computing device, and you can transact with OpenBazzar vendors without paying transaction fees. The “no rules” ethos of the protocol means that personal reputation will be even more important to business interactions than it currently is on eBay.
Crowdfunding initiatives like Kickstarter and Gofundme are doing the advance work for the emerging peer-to-peer economy. The popularity of these sites suggests people want to have a direct say in product development. Blockchains take this interest to the next level, potentially creating crowd-sourced venture capital funds.
In 2016, one such experiment, the Ethereum-based DAO (Decentralized Autonomous Organization), raised an astonishing $200 million USD in just over two months. Participants purchased “DAO tokens” allowing them to vote on smart contract venture capital investments (voting power was proportionate to the number of DAO they were holding). A subsequent hack of project funds proved that the project was launched without proper due diligence, with disastrous consequences. Regardless, the DAO experiment suggests the blockchain has the potential to usher in “a new paradigm of economic cooperation.”
By making the results fully transparent and publicly accessible, distributed database technology could bring full transparency to elections or any other kind of poll taking. Ethereum-based smart contracts help to automate the process.
The app, Boardroom, enables organizational decision-making to happen on the blockchain. In practice, this means company governance becomes fully transparent and verifiable when managing digital assets, equity or information.
#5 Supply chain auditing
Consumers increasingly want to know that the ethical claims companies make about their products are real. Distributed ledgers provide an easy way to certify that the backstories of the things we buy are genuine. Transparency comes with blockchain-based timestamping of a date and location — on ethical diamonds, for instance — that corresponds to a product number.
The UK-based Provenance offers supply chain auditing for a range of consumer goods. Making use of the Ethereum blockchain, a Provenance pilot project ensures that fish sold in Sushi restaurants in Japan have been sustainably harvested by its suppliers in Indonesia.
#6 File storage
Decentralizing file storage on the internet brings clear benefits. Distributing data throughout the network protects files from getting hacked or lost.
InterPlanetary File System (IPFS) makes it easy to conceptualize how a distributed web might operate. Similar to the way a BitTorrent moves data around the internet, IPFS gets rid of the need for centralized client-server relationships (i.e., the current web). An internet made up of completely decentralized websites has the potential to speed up file transfer and streaming times. Such an improvement is not only convenient. It’s a necessary upgrade to the web’s currently overloaded content-delivery systems.
#7 Prediction markets
The crowdsourcing of predictions on event probability is proven to have a high degree of accuracy. Averaging opinions cancels out the unexamined biases that distort judgment. Prediction markets that payout according to event outcomes are already active. Blockchains are a “wisdom of the crowd” technology that will no doubt find other applications in the years to come.
The prediction market application Augur makes share offerings on the outcome of real-world events. Participants can earn money by buying into the correct prediction. The more shares purchased in the correct outcome, the higher the payout will be. With a small commitment of funds (less than a dollar), anyone can ask a question, create a market based on a predicted outcome, and collect half of all transaction fees the market generates.
#8 Protection of intellectual property
As is well known, digital information can be infinitely reproduced — and distributed widely thanks to the internet. This has given web users globally a goldmine of free content. However, copyright holders have not been so lucky, losing control over their intellectual property and suffering financially as a consequence. Smart contracts can protect copyright and automate the sale of creative works online, eliminating the risk of file copying and redistribution.
Mycelia uses the blockchain to create a peer-to-peer music distribution system. Founded by the UK singer-songwriter Imogen Heap, Mycelia enables musicians to sell songs directly to audiences, as well as license samples to producers and divvy up royalties to songwriters and musicians — all of these functions being automated by smart contracts. The capacity of blockchains to issue payments in fractional cryptocurrency amounts (micropayments) suggests this use case for the blockchain has a strong chance of success.
#9 Internet of Things (IoT)
What is the IoT? The network-controlled management of certain types of electronic devices — for instance, the monitoring of air temperature in a storage facility. Smart contracts make the automation of remote systems management possible. A combination of software, sensors, and the network facilitates an exchange of data between objects and mechanisms. The result increases system efficiency and improves cost monitoring.
The biggest players in manufacturing, tech, and telecommunications are all vying for IoT dominance. Think Samsung, IBM, and AT&T. A natural extension of existing infrastructure controlled by incumbents, IoT applications will run the gamut from predictive maintenance of mechanical parts to data analytics, and mass-scale automated systems management.
#10 Neighbourhood Microgrids
Blockchain technologies enables the buying and selling of the renewable energy generated by neighborhood microgrids. When solar panels make excess energy, Ethereum-based smart contracts automatically redistribute it. Similar types of smart contract automation will have many other applications as the IoT becomes a reality.
Located in Brooklyn, Consensys is one of the foremost companies globally that is developing a range of applications for Ethereum. One project they are partnering on is Transactive Grid, working with the distributed energy outfit, LO3. A prototype project currently up and running uses Ethereum smart contracts to automate the monitoring and redistribution of microgrid energy. This so-called “intelligent grid” is an early example of IoT functionality.
#11 Identity management
There is a definite need for better identity management on the web. The ability to verify your identity is the lynchpin of financial transactions that happen online. However, remedies for the security risks that come with web commerce are imperfect at best. Distributed ledgers offer enhanced methods for proving who you are, along with the possibility to digitize personal documents. Having a secure identity will also be important for online interactions — for instance, in the sharing economy. A good reputation, after all, is the most important condition for conducting transactions online.
Developing digital identity standards is proving to be a highly complex process. Technical challenges aside, a universal online identity solution requires cooperation between private entities and the government. Add to that the need to navigate legal systems in different countries and the problem becomes exponentially difficult. An E-Commerce on the internet currently relies on the SSL certificate (the little green lock) for secure transactions on the web. Netki is a startup that aspires to create an SSL standard for the blockchain. Having recently announced a $3.5 million seed round, Netki expects a product launch in early 2017.
#12 AML and KYC
Anti-money laundering (AML) and know your customer (KYC) practices have a strong potential for being adapted to the blockchain. Currently, financial institutions must perform a labor-intensive multi-step process for each new customer. KYC costs could be reduced through cross-institution client verification and at the same time increase monitoring and analysis effectiveness.
Startup Polycoin has an AML/KYC solution that involves analyzing transactions. Those transactions identified as being suspicious are forwarded on to compliance officers. Another startup, Tradle is developing an application called Trust in Motion (TiM). Characterized as an “Instagram for KYC”, TiM allows customers to take a snapshot of key documents (passport, utility bill, etc.). Once verified by the bank, this data is cryptographically stored on the blockchain.
#13 Data management
Today, in exchange for their personal data people can use social media platforms like Facebook for free. In future, users will have the ability to manage and sell the data their online activity generates. Because it can be easily distributed in small fractional amounts, Bitcoin — or something like it — will most likely be the currency that gets used for this type of transaction.
The MIT project Enigma understands that user privacy is the key precondition for creating of a personal data marketplace. Enigma uses cryptographic techniques to allow individual data sets to be split between nodes and at the same time run bulk computations over the data group as a whole. Fragmenting the data also makes Enigma scalable (unlike those blockchain solutions where data gets replicated on every node). A Beta launch is promised within the next six months.
#14 Land title registration
As Publicly-accessible ledgers, blockchains can make all kinds of record-keeping more efficient. Property titles are a case in point. They tend to be susceptible to fraud, as well as costly and labor-intensive to administer.
A number of countries are undertaking blockchain-based land registry projects. Honduras was the first government to announce such an initiative in 2015, although the current status of that project is unclear. This year, the Republic of Georgia cemented a deal with the Bitfury Group to develop a blockchain system for property titles. Reportedly, Hernando de Soto, the high-profile economist, and property rights advocate will be advising on the project. Most recently, Sweden announced it was experimenting with a blockchain application for property titles.
#15 Stock trading
The potential for added efficiency in share settlement makes a strong use case for blockchains in stock trading. When executed peer-to-peer, trade confirmations become almost instantaneous (as opposed to taking three days for clearance). Potentially, this means intermediaries — such as the clearing house, auditors and custodians — get removed from the process.
Numerous stock and commodities exchanges are prototyping blockchain applications for the services they offer, including the ASX (Australian Securities Exchange), the Deutsche Börse (Frankfurt’s stock exchange) and the JPX (Japan Exchange Group). Most high profile because the acknowledged first mover in the area, is the Nasdaq’s Linq, a platform for private market trading (typically between pre-IPO startups and investors). A partnership with the blockchain tech company Chain, Linq announced the completion of it its first share trade in 2015. More recently, Nasdaq announced the development of a trial blockchain project for proxy voting on the Estonian Stock Market.
The New Blockchain Internet Is Here
Freedom From The Grips Of BIG BROTHER
It’s 2018 – Blockchain is on its way to Become the New Internet
Jan 4, 2018 · 8 min read
A new year has begun. Looking back to 2017 it was truly a wild ride on the crypto rollercoaster. Alt coins experienced massive growth and attention. Part of this can be credited to Bitcoin’s wild ride of all time highs, followed by massive corrections. Thankfully, hopefully, this is behind us.
Perhaps Bitcoin was the sacrificial lamb. Perhaps, the poster child. What Bitcoin most definitely did, was introduce cryptocurrency and the blockchain to the world. Whether people understood it or not, they threw money at it. To this day exchanges still have waitlists for new users, institutional money is slowly creeping into the market, and the influx of capital does not appear to be slowing any time soon.
Since the beginning of 2017 the industry has seen some insane growth.
- Bitcoin market cap $18 bil → $736 bil [USD]
- Total market cap (excluding Bitcoin) $2 bil → $481 bil [USD]
For the first time in history this gives the entire cryptocurrency/blockchain industry a market cap well over $1 trillion dollars!
Something interesting that you may have noticed from the values above is that the rest of the industry is growing (in terms of market cap) considerably faster than Bitcoin. In fact, in 2017 the rest of the industry grew 6x faster than Bitcoin.
To dive a little deeper, we can look at the percentage of total market cap of Bitcoin compared to the rest of the industry. Since December 1, 2017 Bitcoin’s market share has decreased from 55% to around 33% which has given way for dozens of other blockchain assets to break into the space.
If I were to be a betting man, in 2018 I would expect to see Ethereum overtake Bitcoin in regards to market share. Without doubt, Ethereum will continue to outperform Bitcoin as far as the team and technology goes. Bitcoin’s governance issues, reluctance to evolve, and extremely high fees may just lead it to its demise.
This being said, I do not think Bitcoin is going to die completely. Bitcoin will never die. And in the case that it does, then at least it will be succeeded by its hard-forked offspring, Bitcoin Cash. Which, I would mention, has a very real chance and overtaking Old Man Bitcoin.
The new Internet
Now, new year, new me, new mindset. If everyone who jumped on the Bitcoin bandwagon could understand one concept, I would love for it to be this.
Cryptocurrencies exists on the blockchain. The blockchain is essentially a new form of the internet. The two terms are not synonymous.
Blockchain technology will power Web 3.0, which I will refer to as ‘the new Internet’. For many this is an unfamiliar term, so here is a quick explanation I grabbed from this great read.
“Web 3.0 has many definitions, but one of the most popular is that of connective intelligence: where the next generation of applications, data, concepts, and people are connected by an unmediated fabric where you don’t need a trust broker like a bank or tech company in the middle to ensure privacy and security.”
A digital currency is a great proof of concept for blockchain technology, but quite frankly, it is one of the least interesting. Blockchain technology is truly quite amazing, and each day we are seeing new, innovative companies forming. As it currently stands, as far as I am concerned, the market is broken into 3 sections.
- Cryptocurrency (Bitcoin, Litecoin, Ripple)
- Platform (Ethereum, NEO, IOTA)
- Utility Token (TRON, EOS, Status)
Until now, the focus has been primarily on cryptocurrencies, but I think that in 2018 the platform and utility tokens will become the focus. Both of these components, more specifically the platform, are crucial because they help define the next generation of internet. This next generation of internet, or Web 3.0., will be comprised of a stack much like the following [ref link.]
- A decentralized transaction layer. (Ethereum — being the strongest)
- A decentralized file storage layer (IPFS and Swarm)
- A decentralized messaging layer (Matrix or Whisper)
- A high throughput computing resource (Golem)
As you can see, the first piece of the puzzle is the transaction layer, or as mentioned above, the platform. The leading blockchain platform is going to be the primary building block for the new internet, and as the current battle goes, Ethereum is winning.
Will Ethereum be the platform?
Ethereum is winning for several reasons. A strong & cohesive development team. Continuous evolution and improvements to their code base. Low transaction fees. But most importantly, the community.
I don’t see how permissioned blockchains that lack cryptoeconomic incentives will ever stand against public permissionless ecosystems. — Andrew Keys, ConsenSyS
As mentioned in this great article, the ecosystems with the most developers typically win. Ethereum already has a thriving developer community. Truffle, the smart contract developer framework, has 250,000+ developer downloads. Infura, which allows secure access to Ethereum and IPFS, now handles over 2 billion requests per day and smoothly scaled to peak at 4.5 billion requests per day one day in December. MetaMask, which brings Ethereum seamlessly to browsers, has over 500,000 active users.
What about the Utility Tokens?
Here’s where it gets interesting. A Utility Token essentially gives a user the ability to gain access to that system’s services.
For example, let’s look at Golem, a decentralized supercomputer. Golem is a global, open sourced, decentralized supercomputer that anyone can access. It’s made up of the combined power of user’s machines, from personal laptops to entire data centers. For users to utilize Golem’s service, to perform some supercomputing that they may need to do, they require Golem’s utility token, GNT.
This is just one example. Beyond this there are endless services that can be offered as utility tokens. This ranges from decentralized exchanges, to free content entertainment systems and infrastructures for decentralized apps to hedge fund and forecasting tools.
As it happens to be, a good majority of these utility tokens are built on top of the Ethereum platform. In order for these tokens to live on the Ethereum blockchain, they must conform to the rules and protocols that Ethereum has set, known as ERC20. So we can call these tokens, ERC20 tokens. What is interesting is that according to coinmarketcap, 91 out of the top 100tokens, by market cap, are ERC20. So nearly all of the largest utility tokens in the market are built on the Ethereum platform. This gives Ethereum quite the head start.
As the Internet commoditized the cost for communication, Ethereum commoditizes our costs of agreement and trust.
2018 may just be the year of the token. It seems like every few days, new players are entering the game, raising millions, and generating massive market caps. Although the entire market is trending upwards, picking the real winners out of the pack at prices < $1.00 can deem quite profitable for an individual.
2018 in blockchain years is the equivalent of 1994 to the 1996 boom of the Internet. We are on the verge of Web 3.0
The number of decentralized apps (Dapps) that can be developed is endless. Here are some interesting avenues that are being explored .
The Operating System (Status)
- With Status your mobile device becomes a light client node on the Ethereum Network, enabling you to access Ethereum’s entire ecosystem from anywhere. Status is more than a messenger. Send payments and smart contracts to friends from within chats, and enjoy encrypted messaging by default, using a peer-to-peer protocol that doesn’t rely on centralized servers.
Monetization of open source code (Bounties)
- The Bounties Network makes it easy to outsource the completion of any task, from code to social marketing, and everything in between. No fees are taken on the bounties you create, encouraging any project to post bounties on all tasks, paying out in any ERC20 token or Ether.
Legal industry (Openlaw)
- OpenLaw is a blockchain-based protocol for the creation and execution of legal agreements. Using OpenLaw, lawyers can more efficiently engage in transactional work and digitally sign and store legal agreements in a highly secure manner, all while leveraging next generation blockchain-based smart contracts.
Supply Chains of the future (Viant)
- Viant is a blockchain-based platform for modelling business processes, tracking assets and building the supply chains of the future. Leveraging cryptographic security and smart contracts, Viant provides organizations verifiable insights as assets are managed and propagated through the entire supply chain.
- The scope of real world applications of this technology is huge! Just think about the size of the industries in the infographic below. On their own, they are massive, let alone collectively.
Scalable Network Capacity (Envion)
- The switch from PoW mining to PoS mining will significantly decrease the power required for a blockchain to run, but until that has been completely implemented, we will require physical mining operations. Not to mention, the need to meet market demand as more and more Dapps are introduced and the number of daily transactions across the blockchain continues to increase.
- Envion has built a highly profitable, global crypto-mining-infrastructure — Hosted in mobile, modular CSC containers — Decentralized placement directly at the energy source. The collapse in the price of solar-power panels has triggered an exponential expansion of new photovoltaic plants worldwide — leading to unprecedented local over capacities on sunny days. Envion can take advantage of this, while powering the blockchain.
Self-sovereign Identities (uPort)
- Register your self-sovereign identity, secure your keys and data, collect badges and credentials, login to decentralized apps, and digitally sign transactions.
- In November 2017, Zug, Switzerland piloted the self-sovereign identity platform and registered the first digital Zug ID on the Ethereum blockchain. A variety of services can be offered through uPort, such as e-signatures, parking fee payment, and an e-voting service. [The first citizen on uPort]
It’s going to be an interesting year!
With all of this said, it is going to be a very interesting year. Decentralized apps will continue to flood into the market, and we very well may see the platform for the internet of the future solidify itself within the market. Grab your popcorn, it’s going to be exciting.
Please note: nothing above is investment advice — you MUST do your own research — this space is unregulated and high risk to the uninformed and naive.
The New Blockchain Internet
Exciting Developments In The New Decentralized Blockchain Internet
Internet initially wasn’t run by “digital landlords” or “giants”. It was intended to be decentralized without these central entities governing who was to stay on the network or where the data of the users was supposed to be stored in the silos dotted around the world.
However, as it happened to the rest of the things, internet, too, saw a change in its landscape partly because of the incompetence of its structure. With time, it became more dependent on centralized governing authorities like Domain Name Systems (DNS) and Certificate Authorities (CAs).
Not only that, as it furthered stepped forward into the era of information technology, its drool-worthy incentives for centralized infrastructure caused the emergence of the likes of Facebook, Google, Apple, and Amazon and soon the whole of the online realm became a trap rather than a network for the users.
