Are The Public and Permissioned Blockchains Same?
The blockchain technology can transform many industries and economies, allowing you to quickly transfer data (do transactions) so that, if necessary, you can check and track them.
Since its inception, the blockchain concept has undergone tremendous changes. Now, thanks to constant research, technology can be used almost everywhere: from payment systems to the Internet of Things (IoT). Developers are trying to find ways to use technology so that they can become part of our lives.
What is the difference between public and private blockchain? What’s better? Today, both public and private blockchains have their pros and cons, but time and convergence — this term is becoming increasingly important in the blockchain community — will lead to the erasure of the clear boundary between them.
So what is the difference?
The most famous public blockchains are used in the field of cryptocurrency. For example, a bitcoin blockchain is used to perform bitcoin transactions, and it is completely transparent. Anyone can join such a blockchain, read or write information to it. Public blockchains are decentralized, that is, there is no one authority that has control over the network, and the data verified by the participants and recorded in the blockchain cannot be changed, and any member who connects to the network can use the public blockchain to record transactions and data. This type of platform is not suitable for organizations that deal with confidential information, such as commercial contracts or personal data of individuals.
Private organizations prefer to join a permissioned blockchain, which allows “invited and authorized” users to make transactions in such a way that no information about this is open and cannot be accidentally dropped into the hands of third parties. Permissioned blockchains, or blockchains with access control, work similarly to the public, but here not everyone can join the network, so such systems are more similar to our usual centralized databases. In permissioned blockchains, the network is usually managed by one or several centers, which means that transactions are carried out with the help of third parties. Permissioned blockchains provide different levels of authority for users, and therefore access may be limited, and information may also be encrypted with varying degrees of complexity in order to protect confidentiality.
As long as they are needed – today, public and permissioned blockchains have enough problems, and first of all, it is confidentiality and scalability. The blockchain structure inevitably raises the issue of confidentiality, but public blockchains gradually solve it, and, probably, in time, the need for permissioned blockchains will disappear. Another problem that affects both public and permissioned blockchains is compatibility between platforms, that is, the ability to share values for users of different networks.
Recap
It is very difficult to determine which blockchain is better – both options have their own advantages and disadvantages. Productivity depends on conditions and goals. The main difference is in the definition of those who are allowed to participate, add and confirm transactions. Permissioned blockchains do not disclose information to the general public, while public ones are accessible to everyone, ensuring full transparency of the information contained in them.
Despite the fact that they have a clear division by functional and purposeful tasks, the potential for combining public and permissioned blockchains has great prospects for both individual and corporate units.

What is Ethereum?
Ethereum (ETH, ether) is both a cryptocurrency and a functional decentralized environment that truly revolutionized the entire IT industry. This platform allows developers to create and deploy decentralized applications (dapps) on it, such as Status or Metamask. As the two leading cryptocurrencies by market capitalization, Bitcoin and Ethereum are often mentioned in the same context. Therefore, it can be difficult for beginners to immediately understand what ethereum is and how it differs radically from bitcoin.
Who are the founders of Ethereum?
The creators of the ether, among whom Vitalik Buterin stands out when launching this platform were pursued by the standard goals for the authors of cryptocurrency – improving Bitcoin. However, it is difficult to name the ether Bitcoin 2.0. They are somewhat similar, but there are a number of conceptual differences between them.
How does it work?
The Ethereum network is a publicly available platform that is decentralized and simplifies the use of blockchain technology. Ethereum cryptocurrency is a payment instrument with great potential. On the basis of the blockchain of Ethereum, many issues can be solved, for example, to certify contracts without the involvement of a notary. Unlike Bitcoin, ETH has more prospects, and its leadership (according to many experts) is only a matter of time.
Methods of storing Ethereum
You have several options for storing ETH. You can leave them on the stock exchange, move them to your wallet on your computer or mobile device, to a stand-alone hardware wallet or to a paper wallet.
From a security point of view, it is not recommended to leave a cryptocurrency on the exchange. Mobile and desktop wallets are a bit safer, but still at risk of hacking. The safest option is to move your tokens to a hardware or paper wallet.
Ways of earning Ethereum?
ETH cryptocurrency in 2017 made a significant spurt in its value, in parallel taking the second place in terms of capitalization among other cryptomonet. This alone was enough for the broadcast to appear on almost all major exchanges, and also to appear in various online exchangers.
The mining option requires an initial investment, be it independent mining of ETH, or the use of cloud services. Ether is one of the main options for “miners” who work with pools. Mining takes place on farms made with powerful graphics cards from Radeon and GeForce. But in the fall of 2017, the first mining ASIC for Ethereum appeared. After that, active conversations about the transition to the PoS protocol began. As soon as the network makes this transition, mining of the ether will become economically unprofitable. Therefore, ETH is difficult to consider as a long-term mining option.
Smart contracts
Smart contracts are the very “secret ingredient” of ethereum. The concept of smart contracts was proposed in 1996 by scientist Nick Sabo. Smart contracts are computer programs that control the transfer of digital currencies or assets between the parties, if certain conditions are met. Ethereum provides the basis for these contracts and at the same time has a level of functionality that is inaccessible to most other cryptocurrencies. It is assumed that the ethereum will find application in areas such as identification systems, insurance payments, etc.
Pros and cons of Ethereum
When it comes to the advantages and disadvantages of Ethereum, it is important to clarify what is at stake: the platform or the cryptocurrency (ether). To begin, let’s talk about the ether – the token (cryptocurrency). There are no serious drawbacks with Ether compared to Bitcoin and other popular coins. Moreover, the network quickly processes transactions, which potentially increases the payment potential of ETH.
Experts agree that one of the key factors in the development of cryptocurrency was the emergence of the full version of Homestead. From this point on, using the platform, you can create applications and projects that are decentralized in nature and using smart contracts. As a result, opened the way for investment. It is also an important advantage that universality can be considered – it supports various programming languages and algorithms of different complexity, and smart contracts are used in different areas.
Bitcoin is now a widely known and used cryptocurrency element. Trading Bitcoin is undoubtedly a greater source of earning money but it is a hectic space. You can easily lose track even if you are out from the loop for a shorter span of time. Still, it is an excellent idea to use or trade Bitcoin but you should sign up only in one online forum.
