You can skip our detailed analysis of these companies, and go directly to the 5 Most Valuable Blockchain Companies in the World. When investors and consumers come across the term 'blockchain', for most of them, the first thing that crosses their mind is Bitcoin.

While Bitcoin and blockchains are inextricably linked, the latter is more diverse than a simple currency, even though it forms the very backbone of what Bitcoin offers, i.

In simple terms, a blockchain is a distributed collection of records, traditionally referred to as a ledger. Any party which uses this ledger for a transaction can access it and make changes, which results in multiple copies with multiple users, a concept that improves transaction integrity. The rise of Bitcoin and associated cryptocurrencies has spurred a corresponding increase in popularity for blockchain technology firms, with the sector as a whole believed by many to be worth billions of dollars in the near-term future.

For instance, a research report by MarketsandMarkets expects the global blockchain market to grow by a staggering compound annual growth rate CAGR The research firm also believes that while small and medium enterprises SMEs will form the backbone of this growth, the largest share of the dollar pie will be made up of traditional financial institutions relying on blockchains.

This research firm projects a CAGR of The firm also lays down in its report that the bulk of this addition will be due to firms using the technology to avoid counterfeit products and fraudulent transactions. We use multiple factors when determining the value of a company. For this list, since some of the firms are not publicly traded, we will use their revenue as the primary determinant of their size. While the list is diverse, it mostly consists of firms that primarily focus on utilizing the blockchain sector for their customer offerings or are financial firms that have added cryptocurrencies to their portfolio, or whose majority of business offerings revolve around providing technology solutions that also include blockchains.

Otherwise, big tech giants including Microsoft Corporation and Amazon. Blockstream is a Canadian company founded in that also offers blockchain solutions for storing and transferring digital assets, the predominant of which is Bitcoin. Like other small blockchain firms, Blockstream also keeps its financial details private since it is not publicly traded and therefore not obligated to share the details publicly.

Intellectsoft is a software solution development firm which was established in It targets businesses and companies as its customers and five offices all over the globe, including one in New York and another in Miami. Deqode, formally known as Techracers, founded in , rose to prominence due to its all-out approach towards blockchain. The company was one of the few at the time to bring the benefits of blockchain to all aspects of the way a business and individuals within it deal with each other.

Some of these aspects include wallets, contract audits, exchanges and private blockchains. Steem is a blockchain company founded in , introducing its first service called the Genesis Block. Since then, it offers its services to three categories of users. These are developers, entrepreneurs and social users. It also offers community and development support programs. A small yet emerging player in the blockchain sector is ConsenSys, which was founded in and provides both cryptocurrency wallets and blockchain solutions.

Unlike other similar companies, who often reveal their revenue, ConsenSys, which is a private firm, keeps relatively mute on such details. Hive Blockchain Technologies Ltd. It also claims to use only renewable energy for mining Bitcoin and Ethereum.

Its mining facilities are based in Canada, Ireland, and Sweden, and it allows its shareholders to access a portfolio of both cryptocurrencies. The company plans to install , miners and achieve a hash rate of Marathon Digital Holdings, Inc.

Throughout the course of , Marathon Digital Holdings, Inc. Argo Blockchain is a company based in London, the United Kingdom which was founded in after the cryptocurrency boom. The company's sole aim was to make sure that mining became a legitimate operation. Argo's operations are primarily based in North America, with the company owning over 21, mining machines that are employed in the United States and Canada.

It has also filed a Form F1 with the U. Binance is one of the world's largest cryptocurrency exchanges. It was founded by Changpeng Zhao and Yi He in and has faced its share of controversy in the United States due to accusations of money laundering and tax crimes. It operates a separate exchange in the U. US which is registered with U. The company reports that on average, two billion transactions take place daily on its network and it offers a decentralized cryptocurrency wallet and a community drive blockchain.

Public blockchains can be secured with automatic validation methods and encryption that keep single entities from changing information in the chain like cryptocurrency blockchains , or they can allow anyone to make changes. The primary disadvantage to secured public blockchains is the heavy energy consumption required to maintain them.

The concern is a consensus mechanism that requires participants to compete to validate the information and receive a reward for letting the network use their processing power. Not all blockchain networks use an energy-intensive validation process, so not all use enormous amounts of electricity. Other issues include the lack of complete privacy and anonymity. Public blockchains allow anyone to view transaction amounts and the addresses involved.

If the address owners become known, the user loses their anonymity. Public blockchains also attract participants who may not be honest in their intentions. Most public blockchains are designed for cryptocurrencies, which by nature of their value are a prime target for hackers and thieves. Participants can join a private blockchain network only through an invitation where their identity or other required information is authentic and verified.

The validation is done by the network operator s or by a clearly defined set protocol implemented by the network through smart contracts or other automated approval methods. Private blockchains control who is allowed to participate in the network. If the network is capable of mining, its private nature could control which users can execute the consensus protocol that decides the mining rights and rewards. Additionally, only select users might maintain the shared ledger.

The owner or operator has the right to override, edit, or delete the necessary entries on the blockchain as required or as they see fit. A private blockchain is not decentralized. It is a distributed ledger that operates as a closed database secured with cryptographic concepts and the organization's needs. By reducing the focus on protecting user identities and promoting transparency, private blockchains prioritize efficiency and immutabilityпїЅthe state of not being able to be changed.

These are important features in supply, logistics, payroll, finances, accounting, and many other enterprise and business areas. While purposefully designed for enterprise applications, private blockchains lose out on many of the valuable attributes of permissionless systems simply because they are not widely applicable. They are instead built to accomplish specific tasks and functions. In this respect, private blockchains are susceptible to data breaches and other security threats.

This is because there is generally a limited number of validators used to reach a consensus about transactions and data if there is a consensus mechanism. In a private blockchain, there may not be consensus but only the immutability of entered data unless an operator or administrator can make changes. Permissioned blockchains are a mix between the public and private blockchains and support many options for customization. Permissioned blockchain advantages include allowing anyone to join the permissioned network after a suitable identity verification process.

Some give special and designated permissions to perform only specific activities on a network. This allows participants to perform particular functions such as reading, accessing, or entering information on the blockchain.

Permissioned blockchains allow for many functions, but one most interesting to businesses is Blockchain-as-a-Service BaaS пїЅa blockchain designed to be scalable for the needs of many companies or tasks that the providers rent out to other businesses. Blockchain-as-a-Service reduces costs for many businesses that can benefit from using blockchain technology in their business processes.

For example, say a business wants to improve transparency and accuracy in its accounting processes and financial reporting.

It could rent blockchain accounting services from a BaaS provider. The blockchain would provide an interface where entries are made by end users and then automates the rest of the accounting processes. In this way, there are fewer errors and no way for other parties to alter financial data after it is entered. As a result, financial reports to management and executives become more accurate, and the blockchain is accessible for viewing and generating real-time financial reports.

The business might choose to have its invoicing, payments, book-keeping, and tax reporting automated. Additionally, blockchain can prevent anyone with dishonest intentions from altering financial data or taking advantage of weaknesses in accounting processes.

The disadvantages of permissioned blockchains mirror those of public and private blockchains, depending on how they are configured.

One key disadvantage is that because permissioned blockchains require internet connections, they are vulnerable to hacking. By design, some might use immutability techniques such as cryptographic security measures and validation through consensus mechanisms. While most blockchains are thought to be unhackable, there are weaknesses. Cryptocurrency theft occurs when a network is hacked into, and private keys are stolen. Permissioned blockchains also suffer this weakness because the networks that connect the users to the service depend on security measures that can be bypassed.

User information can be stolen and accounts hacked into, similar to enterprise-level data breaches like the one Target suffered in when a third-party with access to the network was hacked. Private blockchains are distributed ledgers only available to those given express permission to have specific access levels or abilities on a blockchain.

Many companies have found utility and value in permissioned blockchains. For example, Walmart uses a custom version of Hyperledger Fabric, which was created as an open source project by IBM and the Linux Foundation for enterprise use, to track food origins much faster than it previously could. A private blockchain is one in which only specific users have access and abilities and is generally used only by the entity it belongs to.

A permissioned blockchain is a hybrid of public and private blockchains where multiple users are given permissions and abilities. Cryptocurrency News. Your Money.
