What are the 4 Types of Blockchain Technology?

Blockchain technology has emerged as a game-changer in various industries, offering unparalleled security, transparency, and efficiency. However, not all firms have the same requirements when it comes to adopting blockchain.

Developers have crafted various blockchain types to meet organizations’ diverse needs.

In this article, we will explore “What are the 4 Types of Blockchain Technology?”: public blockchain, private blockchain, hybrid blockchain, and consortium blockchain. Let’s dive in and understand each type in detail.

Overview

Blockchain, in its essence, is a decentralized database that is shared among computer network nodes. It enables the secure recording and verification of transactions using cryptographic hashes and a distributed ledger.

The technology eliminates the need for a central authority, ensuring data integrity and preventing fraud and data tampering.

What is Blockchain?

Blockchain is a decentralized database that allows for the secure recording and verification of transactions.

It operates on the principle of a distributed ledger, where transactional data is divided into blocks and linked together using cryptographic hashes.

This unique ID ensures data integrity and prevents tampering or unauthorized changes. Blockchain technology has gained popularity due to its ability to eliminate the need for intermediaries, increase transparency, and enhance security.

Why Do We Need Different Types of Blockchain?

Different organizations have distinct requirements when it comes to blockchain technology.

While some may prioritize openness and transparency, others may require more control over their network. To cater to these diverse needs, different types of blockchains have been developed.

Each type offers specific characteristics and benefits, allowing organizations to choose the most suitable option for their operations. Let’s explore the 4 main types of blockchain technology in detail.

 

What are the four Types of Blockchain Technology?

Public Blockchain

A public blockchain, also known as a permissionless blockchain, is a distributed ledger where anyone with an internet connection can join and conduct transactions.

It is a non-restrictive form of blockchain, with each participating node having a copy of the entire blockchain.

This openness allows for transparency, as all authorized nodes can access and verify transactions.

Public blockchains often use consensus algorithms like Proof of Work (PoW) or Proof of Stake (PoS) to validate transactions and secure the network.

Advantages of the Public Blockchain:

  • Trustable: Public blockchains use consensus algorithms to ensure the authenticity of transactions and prevent fraud.
  • Secure: A large number of participants in a public blockchain makes it highly secure, as hacking the entire network requires tremendous computational power.
  • Open and Transparent: Public blockchains provide transparency, as all authorized nodes have access to the blockchain records.

Disadvantages of the Public Blockchain:

  • Lower TPS: Public blockchains have a lower transaction processing speed as the consensus algorithms require time to validate transactions.
  • Scalability Issues: As the network expands, the processing speed of public blockchains decreases, posing scalability challenges.
  • High Energy Consumption: Proof of Work consensus algorithms, used in public blockchains like Bitcoin, consume significant energy. Energy-efficient consensus methods are essential for the future of public blockchains.

Uses of the Public Blockchain:

  • Cryptocurrencies: Public blockchains like Bitcoin and Ethereum are widely used for mining and exchanging cryptocurrencies.
  • Notarization: Public blockchains can be used for creating a fixed record with an auditable chain of custody, such as electronic notarization of documents.
  • Social Support Groups: Organizations built on transparency and trust, such as social support groups, can benefit from the openness of public blockchains.

Private Blockchain

Private blockchains, often called permissioned blockchains, function within closed networks or under the control of a single organization.

In contrast to public blockchains, private blockchains are confined to a chosen group of participants.

Additionally, these participants are granted access to the blockchain network, which is often password-protected.

Private blockchains provide organizations with more control and privacy over their data, making them suitable for internal operations.

Advantages of Private Blockchain:

  • Speed: Private blockchains outpace their public counterparts in transaction processing speed due to their restricted node count.
  • Scalability: Organizations can easily scale their private blockchains to meet their specific requirements, making them highly scalable.

Disadvantages of Private Blockchain:

  • Trust Building: In a private blockchain, trust extends only to participating nodes, which the controlling organization pre-approved.
  • Lower Security: Private blockchains are more vulnerable to security breaches compared to public blockchains as they have a smaller number of nodes.
  • Centralization: Private blockchains require a central Identity and Access Management (IAM) system, which can limit decentralization.

Uses of Private Blockchain:

  • Supply Chain Management: Private blockchains can be used to manage supply chain operations within an organization, ensuring transparency and trust.
  • Asset Ownership: Private blockchains can track and verify asset ownership, providing a secure and auditable record.
  • Internal Voting: Private blockchains can enable internal voting processes within organizations.

 

Hybrid Blockchain

Hybrid blockchain combines the features of both public and private blockchains, offering the best of both worlds.

Furthermore, it allows organizations to create a private, permission-based system alongside a public, permissionless system.

Hybrid blockchains maintain private transactions and records, yet validation is possible via smart contracts when needed.

Advantages of Hybrid Blockchain:

  • Secure: Hybrid blockchains operate within a closed environment, preventing external attacks on the network.
  • Cost-Effective: Hybrid blockchains provide privacy while allowing communication with third parties. Transactions are inexpensive and quick, with better scalability than public blockchains.

Additionally, here are the disadvantages of Hybrid Blockchain:

  • Lack of Transparency: Hybrid blockchains may lack full transparency as certain information can be hidden from public view.
  • Less Incentive: Upgrading a hybrid blockchain can be challenging, and users may have little incentive to participate in or contribute to the network.

Uses of Hybrid Blockchain:

  • Real Estate: Real estate companies can use hybrid blockchains to run their systems privately while offering certain information, such as property listings, to the public.
  • Retail: Hybrid blockchains can streamline retail processes, ensuring secure and transparent transactions.
  • Highly Regulated Markets: Industries like banking, which operate in highly regulated environments, can benefit from the privacy and security of hybrid blockchains.

Consortium Blockchain

Consortium blockchain, also known as federated blockchain, involves multiple organizations collaborating on a decentralized network.

Additionally, unlike public or private blockchains, consortium blockchains require consensus among predetermined nodes.

These nodes are responsible for initiating, receiving, and validating transactions within the network.

Advantages of Consortium Blockchain:

  • Secure: Consortium blockchains offer enhanced security, scalability, and efficiency compared to public blockchains.
  • Access Controls: Consortium blockchains provide access controls, allowing organizations to determine which nodes can validate transactions.

Disadvantages of Consortium Blockchain:

  • Lack of Transparency: Consortium blockchains may have lower transparency compared to public blockchains, and a security breach can compromise the network’s functionality.
  • Centralized Governance: Consortium blockchains require a centralized governance structure, which provides administrative and monitoring capabilities.

Uses of the Consortium Blockchain:

  • Banking and Payments: Banks can form a consortium blockchain to collaborate on secure and transparent transactions.
  • Research: Research organizations can use consortium blockchains to share data and outcomes securely.
  • Supply Chain Management: Consortiums of organizations can utilize blockchain to track and verify supply chain operations.

 

Conclusion: What are the four Types of Blockchain Technology?

In conclusion, the 4 different types of blockchain technology cater to the diverse needs of organizations.

Furthermore, public blockchains offer openness and transparency, while private blockchains provide control and privacy.

Additionally, hybrid blockchains combine the benefits of both public and private blockchains, and consortium blockchains allow collaboration among multiple organizations.

Understanding the characteristics and use cases of each type is crucial for organizations to choose the most suitable blockchain for their operations.

As blockchain technology continues to evolve, it will reshape industries and revolutionize the way we conduct transactions and manage data.

Musk Turns On Starlink to Save Iranians from Regime’s Internet Crackdown

Elon Musk, the world’s richest man and a visionary behind SpaceX, has flipped the switch on Starlink, delivering internet to Iranians amid a brutal regime crackdown.

This move comes on the heels of Israeli strikes targeting Iran’s nuclear facilities, as the Islamic Republic cuts off online access.

The former Department of Government Efficiency chief activated Starlink satellite internet service for Iranians on Saturday following the Islamic Republic's decision to impose nationwide internet restrictions.

As the Jerusalem Post reports, that the Islamic Republic’s Communications Ministry announced the move, stating, "In view of the special conditions of the country, temporary restrictions have been imposed on the country’s internet."

This action followed a series of Israeli attacks on Iranian targets.

Starlink, a SpaceX-developed satellite constellation, provides high-speed internet to regions with limited connectivity, such as remote areas or conflict zones.

Elizabeth MacDonald, a Fox News contributor, highlighted its impact, noting, "Elon Musk turning on Starlink for Iran in 2022 was a game changer. Starlink connects directly to SpaceX satellites, bypassing Iran’s ground infrastructure. That means even during government-imposed shutdowns or censorship, users can still get online, and reportedly more than 100,000 inside Iran are doing that."

During the 2022 "Woman, Life, Freedom" protests, Starlink enabled Iranians to communicate and share footage globally despite network blackouts," she added.

MacDonald also mentioned ongoing tests of "direct-to-cell" capabilities, which could allow smartphone connections without a dish, potentially expanding access and supporting free expression and protest coordination.

Musk confirmed the activation, noting on Saturday, "The beams are on."

This follows the regime’s internet shutdowns, which were triggered by Israeli military actions.

Adding to the tension, Israeli Prime Minister Benjamin Netanyahu addressed the Iranian people on Friday, urging resistance against the regime.

"Israel's fight is not against the Iranian people. Our fight is against the murderous Islamic regime that oppresses and impoverishes you,” he said.

Meanwhile, Reza Pahlavi, the exiled son of Iran’s last monarch, called on military and security forces to abandon the regime, accusing Supreme Leader Ayatollah Ali Khamenei in a Persian-language social media post of forcing Iranians into an unwanted war.

Starlink has been a beacon in other crises. Beyond Iran, Musk has leveraged Starlink to assist people during natural disasters and conflicts.

In the wake of hurricanes and earthquakes, Starlink has provided critical internet access to affected communities, enabling emergency communications and coordination.

Similarly, during the Ukraine-Russia conflict, Musk activated Starlink to support Ukrainian forces and civilians, ensuring they could maintain contact and access vital information under dire circumstances.

The genius entrepreneur, is throwing a lifeline to the oppressed in Iran, and the libs can’t stand it.

Conservative talk show host Mark Levin praised Musk’s action, reposting a message stating that Starlink would "reconnect the Iranian people with the internet and put the final nail in the coffin of the Iranian regime."

"God bless you, Elon. The Starlink beams are on in Iran!" Levin wrote.

Musk, who recently stepped down from leading the DOGE in the Trump administration, has apologized to President Trump for past criticisms, including his stance on the One Big Beautiful Bill.

GENIUS Act lets State banks conduct some business nationwide. Regulators object

The Senate passed the GENIUS Act for stablecoins last week, but significant work remains before it becomes law. The House has a different bill, the STABLE Act, with notable differences that must be reconciled. State banking regulators have raised strong objections to a provision in the GENIUS Act that would allow state banks to operate nationwide without authorization from host states or a federal regulator.

The controversial clause permits a state bank with a regulated stablecoin subsidiary to provide money transmitter and custodial services in any other state. While host states can impose consumer protection laws, they cannot require the usual authorization and oversight typically needed for out-of-state banking operations.

The Conference of State Bank Supervisors welcomed some changes in the GENIUS Act but remains adamantly opposed to this particular provision. In a statement, CSBS said:

“Critical changes must be made during House consideration of the legislation to prevent unintended consequences and further mitigate financial stability risks. CSBS remains concerned with the dramatic and unsupported expansion of the authority of uninsured banks to conduct money transmission or custody activities nationwide without the approval or oversight of host state supervisors (Sec. 16(d)).”

The National Conference of State Legislatures expressed similar concerns in early June, stating:

“We urge you to oppose Section 16(d) and support state authority to regulate financial services in a manner that reflects local conditions, priorities and risk tolerances. Preserving the dual banking system and respecting state autonomy is essential to the safety, soundness and diversity of our nation’s financial sector.”

Evolution of nationwide authorization

Section 16 addresses several issues beyond stablecoins, including preventing a recurrence of the SEC’s SAB 121, which forced crypto assets held in custody onto balance sheets. However, the nationwide authorization subsection was added after the legislation cleared the Senate Banking Committee, with two significant modifications since then.

Originally, the provision applied only to special bank charters like Wyoming’s Special Purpose Depository Institutions or Connecticut’s Innovation Banks. Examples include crypto-focused Custodia Bank and crypto exchange Kraken in Wyoming, plus traditional finance player Fnality US in Connecticut. Recently the scope was expanded to cover most state chartered banks with stablecoin subsidiaries, possibly due to concerns about competitive advantages.

Simultaneously, the clause was substantially tightened. The initial version allowed state chartered banks to provide money transmission and custody services nationwide for any type of asset, which would include cryptocurrencies. Now these activities can only be conducted by the stablecoin subsidiary, and while Section 16(d) doesn’t explicitly limit services to stablecoins, the GENIUS Act currently restricts issuers to stablecoin related activities.

However, the House STABLE Act takes a more permissive approach, allowing regulators to decide which non-stablecoin activities are permitted. If the House version prevails in reconciliation, it could result in a significant expansion of allowed nationwide banking activities beyond stablecoins.

Is it that bad?

As originally drafted, the clause seemed overly permissive.

The amended clause makes sense for stablecoin issuers. They want to have a single regulator and be able to provide the stablecoin services throughout the United States. But it also leans into the perception outside of crypto that this is just another form of regulatory arbitrage.

The controversy over Section 16(d) reflects concerns about creating a regulatory gap that allows banks to operate interstate without the oversight typically required from either federal or state authorities. As the two Congressional chambers work toward reconciliation, lawmakers must decide whether stablecoin legislation should include provisions that effectively reduce traditional banking oversight requirements.

Dubai regulator VARA classifies RWA issuance as licensed activity
Virtual Asset Regulatory Authority (VARA) leads global regulatory framework - makes RWA issuance licensed activity in Dubai.

Real-world assets (RWAs) issuance is now licensed activity in Dubai.

~ Actual law.
~ Not a legal gray zone.
~ Not a whitepaper fantasy.

RWA issuance and listing on secondary markets is defined under binding crypto regulation.

It’s execution by Dubai.

Irina Heaver explained:

“RWA issuance is no longer theoretical. It’s now a regulatory reality.”

VARA defined:

- RWAs are classified as Asset-Referenced Virtual Assets (ARVAs)

- Secondary market trading is permitted under VARA license

- Issuers need capital, audits, and legal disclosures

- Regulated broker-dealers and exchanges can now onboard and trade them

This closes the gap that killed STOs in 2018.

No more tokenization without venues.
No more assets without liquidity.

UAE is doing what Switzerland, Singapore, and Europe still haven’t:

Creating enforceable frameworks for RWA tokenization that actually work.

Matthew White, CEO of VARA, said it perfectly:

“Tokenization will redefine global finance in 2025.”

He’s not exaggerating.

$500B+ market predicted next year.

And the UAE just gave it legal rails.

~Real estate.
~Private credit.
~Shariah-compliant products.

Everything is in play.

This is how you turn hype into infrastructure.

What Dubai is doing now is 3 years ahead of everyone else.

Founders, investors, ecosystem builders:

You want to build real-world assets onchain.

Don’t waste another year waiting for clarity.

Come to Dubai.

It’s already here.
