Public, private and permissioned blockchains compared

Public, private and authorized: an overview

Public blockchains allow access to anyone; private blockchains are available to selected or authorized users; Permissioned blockchains have different levels of permissions or user roles.

Many cryptocurrencies are built on open-source public blockchains. Others are permissioned as they can be used by anyone, but roles are assigned and only specific users can make changes.

Private and permissioned blockchains are generally used by organizations or businesses with specific needs.

Key points

  • In a public blockchain, anyone can join and participate in the core activities of the network.
  • A private blockchain allows only selected and verified participants; the operator has the right to overwrite, modify or delete entries on the blockchain.
  • Permissioned blockchains assign specific roles or permissions to various users on the network.

Public blockchain

An audience blockchain it is one where anyone is free to join and participate in the core activities of the blockchain network. Anyone can read, write, or control ongoing activity on a public blockchain network, which helps achieve the self-governing, decentralized nature often touted when talking about cryptocurrency blockchains.

Advantages

A public network operates under an incentive scheme that encourages new participants to join. Public blockchains offer a particularly valuable solution from the perspective of a truly decentralized, democratized, and authority-free operation.

Public blockchains are extraordinarily valuable because they can serve as the backbone for almost anyone decentralized solution. Additionally, the vast number of network participants who join a secure public blockchain keeps it safe from data breaches, hacking attempts, or other cybersecurity issues. The more participants, the more secure a blockchain is.

Public blockchains can be secured with automatic validation methods and cryptography that prevent individual entities from changing information in the chain (such as cryptocurrency blockchains), or can allow anyone to make changes.

Disadvantages

One concern with public blockchains is security. Some designers have solved this using a competitive, distributed block/reward validation/proposal system, while others have solved it using a collateralized system.

Other issues include the lack of complete privacy and anonymity. Public blockchains allow anyone to view transaction amounts and the addresses involved. If the owners of the address are revealed, 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, due to the nature of their value, are a prime target for hackers and thieves.

Private blockchain

Participants can join a private blockchain network only through an invitation where their identity or other requested information is authentic and verified. Validation is performed by the network operator(s) or by a clearly defined protocol implemented by the network via smart contracts or other automated approval methods.

Therefore, private blockchains control who is allowed to participate in the network. The owner or operator has the right to overwrite, modify or delete necessary entries on the blockchain as required or as he sees fit or make programming changes.

Advantages

A private blockchain is not decentralized. It’s a distributed ledger which works as a closed database protected by cryptographic concepts and the needs of the organization. Only those with permission can run a full node, make transactions, or validate/authenticate changes to the blockchain.

By reducing the focus on protecting user identities and promoting transparency, private blockchains prioritize efficiency and immutability, the state in which you cannot change.

These are important features in procurement, logistics, payroll, finance, accounting and many other business and commercial areas.

Disadvantages

Although designed specifically for enterprise applications, private blockchains lose many of the valuable attributes of permissionless systems simply because they are not widely applicable. Instead, they are built to perform specific tasks and functions.

In this regard, private blockchains are susceptible to data breaches and other security threats. This is because there are generally a limited number of validators used to reach consensus on transactions and data if a consensus mechanism exists. In a private blockchain there may not be a need for consensus but only for the immutability of the data entered.

Blockchain permissioned

Permissioned blockchains generally have similar features to public and private blockchains, with many customization options.

Advantages

The benefits of permissioned blockchain include the ability to allow anyone to join the permissioned network after a proper identity verification process. Some grant special, designated permissions to perform only specific tasks on a network. This allows participants to perform particular functions such as reading, accessing or entering information on the blockchain.

Permissioned blockchains enable many functions, but the most interesting one for businesses is Blockchain as a Service (BaaS)—a blockchain designed to be scalable for the needs of many businesses or businesses that vendors rent to other businesses.

Blockchain-as-a-Service reduces costs for many companies that can benefit from using blockchain technology in their business processes.

For example, let’s say a company wants to improve the transparency and accuracy of its accounting processes and financial reporting. It could rent blockchain accounting services from a BaaS provider. Blockchain would provide an interface where entries are made by end users and then automate the rest of the accounting processes using encryption, verification and consensus techniques.

This way there would be fewer errors and there would be no way for someone to alter the financial data after entering it. As a result, financial reports for management and executives become more accurate, and blockchain is accessible to view and generate real-time financial reports.

The company could also choose to have blockchain and supporting systems automate invoicing, payments, accounting and tax reporting.

Disadvantages

The disadvantages of permissioned blockchains mirror those of public and private blockchains, depending on how they are configured. One major drawback is that because permissioned blockchains require internet connections, they are vulnerable to hackers. By design, some may use immutability techniques such as cryptographic security measures and validation through consensus mechanisms.

While most blockchains are believed to be unhackable, they do have weaknesses without proper precautions. Cryptocurrency theft occurs when applications and supporting programs on a blockchain network are hacked and private keys are stolen. Even permissioned blockchains suffer from this weakness because the networks and applications that connect to blockchain services depend on security measures that can be bypassed.

What are private blockchains?

Private blockchains are distributed ledgers available only to those who have been given express permission to have specific levels of access or abilities on a blockchain.

Are there authorized Blockchains?

Many businesses have found utility and value in permissioned blockchains. For example, Walmart uses a customized version of Hyperledger Fabric, created as an open source project by IBM and the Linux Foundation for enterprise use, to trace food origins much faster than it could previously.

What is the Difference Between Permissioned and Private Blockchain?

A private blockchain is one where only specific users have access and capabilities and is generally only used by the entity to which it belongs. A permissioned blockchain is one in which multiple users are granted permissions and capabilities.

The bottom line

Public blockchains allow anyone to participate. Permissioned blockchains create different roles and have known users. Private blockchains are used by entities that need a secure ledger, allowing access only to those who need it.

Blockchain Technology Will Transform Water Access and Management Globally

Disclosure: The views and opinions expressed here are solely those of the author and do not represent the views and opinions of the crypto.news editorial team.

Access to clean water is a basic human need, yet billions of people around the world still struggle to get it. According to the World Health Organization, over 2 billion people live in countries suffering from severe water stress, and this number is expected to continue to grow due to climate change and population growth.

Traditional water management systems have struggled to address these challenges, often hampered by inefficiencies, lack of transparency, and misallocation of resources. Blockchain technology offers a promising solution to these challenges, providing equitable access and sustainable use of this crucial resource.

The current state of water management

Water management today faces several pressing issues. Inefficiencies in water supply, distribution, and use, coupled with a lack of real-time monitoring, often result in resource waste and misallocation. Many water sources fail to realize their full potential due to infrastructure and financing shortfalls. For example, the Environmental Protection Agency (EPA) report indicated that the United States would need to invest $625 billion over the next 20 years to repair, maintain and improve the country’s drinking water infrastructure due to aging pipes and other infrastructure problems. Additionally, in the United States alone, household leaks can to waste nearly 900 billion gallons of water per year nationwide. This is equivalent to the annual domestic water consumption of nearly 11 million homes.

Furthermore, corruption and mismanagement of water resources can cause unequal distribution, with disadvantaged communities often bearing the brunt of water scarcity. For example, South Africa is struggling with myriad challenges to its water security: drought, inadequate water conservation measures, outdated infrastructure, and unequal access to water resources. The country faces significant water scarcity, with demand expected to outstrip supply by 2030, creating a projected gap of 17%.

Furthermore, the global water industry is highly monopolized, with a few key players controlling a significant share of the market. These companies exert substantial influence over the water supply chain, often prioritizing profit over equitable distribution and environmental responsibility. This concentration of power can lead to inflated prices and limited access for vulnerable populations. The global bottled water market alone is projected to reach $509.18 billion by 2030, with these large companies capturing a significant share of revenue. This monopolization exacerbates existing inequalities in water access and highlights the need for more decentralized and community-driven water management solutions.

The potential of blockchain in water management

Blockchain technology can address these issues by providing a transparent, secure, and decentralized platform for water resource management. This approach offers several advantages:

  • Transparency and accountability. Blockchain’s immutable ledger ensures that all transactions and data entries are transparent and cannot be changed once recorded. This transparency can reduce corruption and ensure that water resources are allocated fairly and efficiently. For example, blockchain can be used to track water usage from source to end user, providing a clear record of how water is distributed and used. This level of transparency can help hold authorities accountable and manage water resources sustainably.
  • Efficient resource management. Blockchain can facilitate the creation of smart contracts, which are self-executing contracts with the terms of the agreement written directly into the code. These contracts can automate water distribution based on real-time data, directing water to where it is needed most. For example, smart contracts could be used to manage urban water supply systems, automatically adjusting water distribution based on real-time consumption patterns and demand. This can help optimize water use, reduce waste, and ensure that households and businesses receive the right amount of water at the right time.

In Dubai, the Dubai Electricity and Water Authority (DEWA) has implemented a blockchain-based smart water network initiative as part of its broader smart city strategy. This project integrates blockchain technology with IoT sensors to monitor water usage in real time, manage distribution, and detect leaks. The decentralized ledger ensures data integrity and transparency, enabling more efficient water management and reduced waste. DEWA’s initiative aims to improve sustainability and resource management in the rapidly growing city, highlighting the potential of blockchain to support urban water management and conservation efforts.

Community participation and ownership

Through blockchain, individuals can directly control and monetize their access to water resources, eliminating the need for third-party intermediaries. This direct control model allows local communities to make collective and transparent decisions about their water use. By managing their water directly from the source, communities can tailor water management practices to their specific needs, promoting equitable distribution and encouraging a sense of accountability and stewardship.

Additionally, future models could allow people to monetize their access to water through web3 technologies. For example, a community-to-business (C2B) model could allow people to sell water directly to companies. In this model, people do not have to own the water directly, but can profit by staking their tokens during event sales pools. This approach not only supports sustainable water management, but also creates economic opportunities for community members. Additionally, a “Burn to Secure” protocol can be used to provide water allocation rights. This protocol provides a true sense of water security and financial opportunity by allowing people to redeem their rights. This system not only secures future water allocations, but also increases token scarcity and value.

Additionally, a pure sense of investment is achieved through investments in water sources. This leads to potential financial returns and dividends by addressing the inefficiencies in water supply mentioned above. By investing to finance infrastructure projects, such as building factories and improving distribution systems, more water can be brought to communities, creating additional economic opportunities.

Monetizing water access through the C2B model, the “Burn to Secure” protocol, and investments in water sources all generate economic benefits for the community, promoting a more equitable and efficient water management system.

Overcoming challenges

While blockchain technology has the potential to improve water management, there are challenges to its adoption. The complexity of blockchain systems and the need for technological infrastructure can be barriers, especially in developing regions. Additionally, there are concerns about the significant energy consumption of blockchain networks. However, technological advances and the development of more energy-efficient blockchain solutions are helping to alleviate these concerns. Additionally, education and capacity building are key to ensuring stakeholders understand how to effectively use blockchain technology. Governments, NGOs, and private sector partners need to work together to provide training and support to communities and water management authorities.

Blockchain technology offers a practical and effective means to improve water management. In addition to addressing inefficiencies, blockchain empowers communities, promotes sustainable practices, and opens up new economic opportunities through models like community-to-business (C2B). As we face the growing challenges of climate change and population growth, blockchain is not only an innovative solution, but represents a fundamental shift in the way we manage and value water resources. Adopting blockchain in water management is essential to creating a sustainable and equitable future by changing the way we interact with and protect our most vital resource.

Nigeria round sign Futuristic satellite view of the world

Nigeria is keeping an eye on a new native blockchain network to protect the country’s data sovereignty.

According to local media, a team from the University of Hertfordshire has proposed the new blockchain, Nigeriato the National Information Technology Development Agency (NITDA).

Chanu Kuppuswamy, who leads the team, argued that relying on blockchain networks whose developers are located in other regions poses national security risks to the Nigerian government. He further said that Nigerium would allow the West African nation to customize the network to meet specific needs, while also promoting data sovereignty.

In his presentation, Chanu cited the recent migration of Ethereum to test of participation (PoS) consensus as an instance in which no Nigerians were involved but whose impact is far-reaching.

“Developing an indigenous blockchain like Nigerium is a significant step towards achieving data sovereignty and promoting trust in digital transactions in Nigeria,” he said.

While receiving the proposals in Abuja, NITDA’s Kashifu Abdullahi acknowledged the benefits a local blockchain would bring to Nigeria, including increased security of citizens’ data.

However, a NITDA spokesperson later clarified that Nigerium is still at the proposal stage and that the government has not yet decided whether to proceed or not.

“The committee is still discussing the possibility with stakeholders. Even if a decision is finally made, there is no guarantee that the name will be Nigerium,” the spokesperson told the media.

Nigerium’s reception in the country has been mixed. Some, like financial analyst Olumide Adesina, To say the network is “dead on arrival”. He believes the Nigerian government’s poor record in following through on its big technology plans will claim another victim. He pointed to the eNaira as a missed opportunity whose chances of success were much higher than those of Nigerium.

Others welcomed the proposal. Chimezie Chuta, who chairs the renewed The Nigerian Blockchain Policy Committee is “extremely optimistic“that Nigerium will be more successful than eNaira.

Speaking to a local news agency, Chuta stressed that eNaira failed because the central bank initiated the project on its own, without involving any stakeholders.

“They just cooked it and expected everyone to like it. [With Nigerium]there will be a lot of collaboration,” he said.

Registration of property title, digital identity and Certificate Verification are among the use cases that Nigerium is expected to initially target. However, Nigeria has already made progress in some of these fields through public blockchains.

SPPG, a leading school in governance and politics, announced in May the country’s first blockchain certificate verification system. Built on the The BSV BlockchainIt was developed in collaboration with the blockchain data recording company VX Technologies and local lender Sterling Bank.

Cambodia’s CBDC developer to construct bond market for Palau on blockchain: report

A Japanese fintech developer will build a blockchain-based bond market gateway for Palau, aiming to launch a trial in 2024 and a full launch the following year.

Japanese fintech developer Suramitsubest known for developing a central bank digital currency (CBDC) for Cambodia, is intended to build a Blockchain-gateway to the bond market based on the Pacific island nation of Palau, Nikkei He learned.

Soramitsu won the contract and plans to introduce the market on a trial basis in fiscal 2024, with a full launch scheduled for the following year, allowing the Palauan government to issue bonds to individual investors and efficiently manage principal and interest payments, according to the report.

The total cost of the project is estimated at several hundred million yen ($1.2 million to $5.6 million), less than half the cost of a non-blockchain alternative, people familiar with the matter said. The project has reportedly received support from Japan’s Ministry of Economy, Trade and Industry, with Japan’s foreign and finance ministries providing strategic and management advice on the project.

Soramitsu’s successful development of Cambodia’s CBDC in 2020 has boosted its reputation, with the digital currency’s popularity soaring, with over 10 million accounts opened by December 2023, representing 60% of Cambodia’s population. Following this, Cambodia’s central bank governor Chea Serey indicated intends to expand the reach of its CBDC internationally, particularly through collaboration with UnionPay International, the Chinese card payment service, and other global partners.

While Soramitsu’s work in Cambodia has been well received, the long-term popularity of CBDCs remains to be seen. As of late June, crypto.news reported a sharp drop in activity in India’s digital currency, the e-rupee, after local banks stopped artificially inflating its values.

According to people familiar with the matter, the Reserve Bank of India managed to hit the 1 million retail transaction milestone last December only after the metrics were artificially infiltrated by local banks, which offered incentives to retail users and paid a portion of the bank’s employees’ salaries using the digital currency.
