What Are the Different Types of Blockchain Networks?

1 min read · 356 views Amala Bastian Oct 05, 2022

Blockchain has gained tremendous popularity in recent years in the industry due to being an immutable and distributed ledger technology. The term “blockchain” figures out to the utilization of a “shared distributed database,” which could make digital transactions for a network of users and trace all of the tangible or intangible assets involved in the transaction. The four major advantages which define a distributed system are higher computing power, cost reduction, higher reliability, and the ability to grow naturally. All of those properties focus on one simple and powerful quality: the system’s integrity to execute smooth and reliable functioning.

Different Types of Blockchain Networks

There are primarily two different types of blockchains: public and private blockchains, and there are two other derivatives: hybrid and consortium. Although there are multiple requirements to consider, different blockchain networks can be used to perform secure transactions in a network.


Public Blockchains: A public blockchain means a permissionless decentralized system where data in the blockchain network is immutable and irreversible. All users in the network can access the chain and any amendments made would result in adding new blocks to the chain. Bitcoin, Ethereum, and Litecoin are examples of public blockchain systems.


Private Blockchains: The significant distinction between public and private blockchains is that the former may be joined by everyone, while only authorized users may enter the latter. This blockchain network can benefit certain organizations or enterprises because they restrict the number of participants or only allow a selected number of participants into a network.


Hybrid Blockchains: Hybrid blockchains exhibit properties of both public and private chains. The hybrid blockchain design is distinguishable because it is not accessible to everyone, but still demonstrates more blockchain features like immutability and irreversibility. The users of hybrid blockchains can choose their participants and decide which transactions are made public. 


Consortium Blockchains: Consortium blockchains are blockchains controlled by a group of organizations, rather than individuals, similar to private blockchains. Consortium blockchains are more decentralized than private blockchains which results in higher levels of security. Consortium blockchains have potential to thrive in businesses, banks, and other payment processors. 



The blockchain's primary application is to perform transactions in a secure network. People utilize blockchain systems for several different purposes. The significant use cases we see today, and may see in the the future, are in the healthcare sectors, digital transactions, NFT (non-fungible token) marketplaces, and real estate management. In 2019, it was estimated that around $2.9 billion was invested in blockchain technology, which represents an 89% increase from the year prior. Additionally, the International Data Corporation has estimated that corporate investment in blockchain technology will reach $12.4 billion by 2022[1]. According to findings from Research and Markets, the worldwide blockchain supply chain industry is expected to reach over $3 billion by 2026[2]. Some countries like China, India, Australia, and Singapore are witnessing growth in a number of start-ups in cryptocurrency and blockchain technology. This means that organizations have joined various conferences to brainstorm how to further develop the technology and understand the value of blockchain.

Investors should consider the investment objectives, risks, charges and expenses carefully before investing. For a prospectus or summary prospectus with this and other information about the Fund, please call 855-425-7426 or visit our website at www.fountetfs.com. Read the prospectus or summary prospectus carefully before investing.

Exchange Traded Concepts, LLC. serves as the investment advisor to the Funds. The Funds are distributed by SEI Investments Distribution Co., (SIDCO) 1 Freedom Valley Drive, Oaks, PA 19456. SIDCO is not affiliated with Exchange Traded Concepts, LLC. or Fount Investment Co. Ltd.

Risk Disclosure:


Investing involves risk, including possible loss of principal. There is no guarantee the Funds will achieve their stated objectives. In addition to the normal risks associated with investing, international investments may involve the risk of capital loss from unfavorable fluctuation in currency values, differences in generally accepted accounting principles, or social, economic, or political instability in other nations. Emerging markets involve heightened risks related to the same factors, as well as increased volatility and lower trading volume. 


The Funds’ concentration in an industry or sector can increase the impact of, and potential losses associated with, the risks from investing in those industries/sectors. For MTVR, the Fund may be concentrated in the entertainment and interactive media & services industries. The entertainment industry is highly competitive and relies on consumer spending and the availability of disposable income for success, which may cause the prices of the securities of companies to fluctuate widely. The prices of the securities of companies in the interactive media & services industry are closely tied to the overall economy's performance. Changes in general economic growth, consumer confidence, and consumer spending may affect them. MTVR may also be subject to the specific risks associated with metaverse companies. These risks include but are not limited to small or limited markets, changes in business cycles, world economic growth, technological progress, rapid obsolescence, and government regulation. Smaller, start-up companies tend to be more volatile than securities of companies that do not rely heavily on technology. Metaverse Companies may rely on a combination of patents, copyrights, trademarks, and trade secret laws to establish and protect their proprietary rights. There can be no assurance that these steps will be adequate to prevent the misappropriation of their technology or that competitors will not develop technologies that are equivalent or superior to such companies’ technology.


For SUBS, the Fund may be concentrated in the software industry. Technological changes, pricing, retaining skilled employees, changes in demand, research & development, and product obsolescence can affect the profitability of software companies causing fluctuations in the market price of company securities. 


Both Funds are subject to communication services sector risk, which can involve the same risks as being concentrated in the software industry. Network security breaches, potential proprietary or consumer information theft, or service disruption can negatively affect companies’ stock prices.


The Funds are non-diversified. The Funds are new and have limited operating histories for investors to evaluate. New and smaller funds may not attract sufficient assets to achieve investment and trading efficiencies. In addition to the normal risks associated with investing, investments in smaller companies typically exhibit higher volatility.
