Top 6 Blockchain Books to Read in 2021

Ethereum is an open-source blockchain-based platform that essentially enables hundreds of decentralized cryptocurrencies and projects to be built and deployed without having to build their own blockchains. With the second largest market cap in the cryptocurrency world, Ethereum has drawn a lot of attention from investors and crypto enthusiasts alike.

Ethereum not only presents a significant change to the status quo, it also allows for the quick development and deployment of new applications presenting niche solutions for various industries. All cryptocurrencies inevitably get compared to Bitcoin, and it frankly makes understanding them much easier. This currency would not require any intermediary financial institutions, but would still ensure safe and valid transactions.

The blockchain is a digital ledger, continuously recording and verifying records. As new blocks are added to the network, they are constantly validated. Similar to Bitcoin, Ethereum is a distributed public blockchain network. While both Ethereum and Bitcoin are cryptocurrencies that can be traded among users, there are many substantial differences between the two. Bitcoin, for example, utilizes blockchain to track ownership of the digital currency, making it an extremely effective peer to peer electronic cash system.

Ethereum, on the other hand, focuses on running the programming code of an application. Application developers largely use it to pay for services and transaction fees on the Ethereum network. Respective miners run each network by validating transactions to earn either bitcoin for Bitcoin or ether for Ethereum. However, it is far from the only application. To take a past example of a similar situation, e-mail is one particular use of the internet, and for sure helped popularise it, but there are many others.

Simply put, Ethereum is a blockchain-based decentralized platform on which decentralized applications Dapps can be built. Smart contracts are scripts that automatically execute tasks when certain conditions are met.

These smart contracts are executed by the Turing-complete Ethereum Virtual Machine EVM , run by an international public network of nodes. The cryptocurrency of the Ethereum network is called ether. Ether serves two different functions:. The underlying technology is complicated even at a surface level. In , a year-old Russian-Canadian boy named Vitalik Buterin learned about Bitcoin from his father. Buterin became a co-founder of Bitcoin Magazine and a leading writer for the publication. Buterin currently serves on the Editorial Board of Ledger.

As a peer-reviewed scholarly journal, Ledger publishes original research articles on cryptocurrency and blockchain technology. The publication shows interest in any topics relating blockchain to mathematics, computer science, engineering, law, and economics. In , after visiting developers across the world who shared an enthusiasm for programming, Buterin published a white-paper proposing Ethereum. This could be accomplished by building a fully-fledged Turing-complete programming language into the Ethereum blockchain.

The Ethereum white paper goes into detail for some of the potential use cases, all of which could be built through decentralized apps on the Ethereum network. The list goes on and on:. Early blockchain applications like Bitcoin only allowed users a set of predefined operations.

For example, Bitcoin was created exclusively to operate as a cryptocurrency. Unlike these early blockchain projects, Ethereum allows users to create their own operations. Since every Ethereum node runs the EVM, applications built on it reap the benefits of being decentralized without having to build their own blockchain. Smart contracts are strings of computer code capable of automatically executing when certain predetermined conditions are met.

This not only makes the entire process more effective, it also makes it more fair and objective. They just have to trust the data feed. Keep in mind that this is only a very simple example. Many smart contracts are extremely complex and can work wonders.

The takeaway: Smart contracts can automate a variety of tasks, without requiring intermediaries. All a smart contract needs is the arbitrary rules written into it. Handling financial transactions alone presents hugely complex problems in terms of reliability and security.

And since the Ethereum network comprises a general purpose blockchain that handles assets other than money, more complex challenges arise beyond mere financial transactions. Moving into the future, Ethereum confronts issues of scalability, energy consumption, security, privacy, and decentralization. As a general purpose blockchain, Ethereum needs a mechanism to represent assets other than money. The ERC standard has been created to transact unique items of value.

The ERC standard originally drove the development of the highly successful CryptoKitties collectibles, but it allows for the representation of any digital asset.

Any blockchain relies on a trustworthy, fair, secure, and reliable consensus protocol for placing transactions onto the system. The Casper finality gadget implements PoS as an independent module. Also as an independent module, this allows the PoW portion of the network to be removed at a later date.

The Casper PoS protocol utilized game theory incentives to maintain the integrity of the system. It also provides benefits of greater security and reduces the massive energy consumption required by PoW mining. Scaling presents a great challenge for Ethereum, as it does for other blockchains. If a user waits too long for a response after clicking a button, frustration results, and users give up on the system.

The web confronted this problem in the early days as well. Web 2. Vitalik Buterin identifies scaling as a primary concern that needs to be addressed in blockchain technology. He made the following comments in September in an interview with Naval Ravikant at the Disrupt SF conference. On the other hand, Uber on average — 12 rides a second, PayPal — several hundred, Visa — several thousand, major stock exchanges — tens of thousands.

Efforts like Lightning and Plasma ease stress on the network by taking work offline to a side chain. Users engage in multiple transactions over time on a channel on the side chain without utilizing the main blockchain at this point. After a number of transactions complete, the final state of these transactions moves over to the main blockchain as a single transaction with a single fee.

Multiple interactions to process thereby reduce to a single action on the blockchain, consequently reducing strain on resources and improving scalability. Computer science boils down to the art of putting something somewhere, then retrieving it when you want it. Storing only what you require in a manner that makes retrieval simple and elegant, and retrieving only what you need, and doing it all as quickly as possible defines efficiency.

Sharding presents a technique for storing data in an efficient manner to improve retrieval. And efficiency determines scalability. Sharding basically defines ways to break data into separate pieces and store them separately. Consequently, you only have to deal with the small piece containing the data you are interested in and not wade through every piece of data contained in the entire system. Database technology has long utilized sharding to increase scalability, and now the Ethereum Foundation researches how sharding can improve blockchain technology.

Similarly, Raiden also presents side chain capability similar to Lighting and Plasma. Raiden is not a project of the Ethereum Foundation but a product of an independent company.

Most of us have a pretty good understanding of what an application app is. An application is formally defined as a program or piece of software designed and written to fulfill a particular purpose of the user.

We use apps every day: Apps allow us to check our bank balance, scroll through a live feed of pictures, or even launch a Flappy Bird into oblivion. Dapps serve similar functions, but run on an entire network of nodes rather than a central source.

The fact that they are decentralized gives dapps an enormous advantage over traditional apps. You know when Instagram is down because the server is down?

How about when Zomato got hacked and exposed the information of 17 million people? While Bitcoin provides a network for financial transactions, Ethereum aspires to provide a platform for decentralized application development. Ultimately, a programming platform requires good applications built on it to be taken seriously.

CryptoKitties gained popularity for a while, but we continue to wait and see how well Ethereum serves as a foundation for application development. He answered as follows :. Some of them are various financial applications, financial contracts, derivatives, things like Maker. Games are another one. In the non-financial space, identity verification is getting to be a big one. With prediction markets, Augur and Gnosis are going to be fairly successful. There are already a huge number of projects, both live and in development, built on the Ethereum network.

Here are just some of the most successful and promising of these dapps. Golem : The Golem project aims to make a global supercomputer easily accessible to anyone. Hold up, have you ever used a supercomputer? Supercomputers cost between a million dollars and a good fraction of a billion dollars. The modern Tianhe-2 Supercomputer has the power of roughly 18, Playstation 4s. Augur would reward users for correctly predicting future events.

While at a surface level it may just seem like a decentralized betting platform which is still worth a lot , Augur could potentially provide powerful predictive data for virtually any industry. Prediction markets are more accurate at forecasting than individual experts, traditional opinion polling, and surveys.

This would not only prevent and provide users with assistance for identity fraud, but it would also remove the need for constant personal information and background verification checks. OmiseGO : OmiseGO vision is to solve the problems and inefficiencies of financial institutions, processors, and gateways by enabling decentralized exchange on a public blockchain at a lower cost and high volume.

This means anyone will be able to conduct financial transactions such as payments, payroll deposits, B2B commerce, supply-chain finance, asset management, and loyalty programs without having to rely on a single server… and without exorbitant fees!
