Franklin Templeton (Publicly listed $1.5T USD financial institution) says, "private blockchains will fade next to fast-innovating public utility chains".

Public vs Private Blockchain InvestaX

Blockchain technology has emerged as a revolutionary solution for a wide range of industries and has been the driving force behind the creation of digital assets like Bitcoin and Ethereum. The global blockchain market is projected to grow from $7.18 billion in 2022 to $163.83 billion by 2029 at a CAGR of 56.3%, according to a report by Fortune Business Insights. When it comes to blockchain, there are two main types: public and private. While private blockchains are typically used by organizations for internal operations, public blockchains have been gaining popularity due to their decentralized nature, making them better suited for certain applications.

Public Blockchain

Public blockchain is an open-source network that allows anyone to participate in the network and validate transactions.Transactions are transparent and can be viewed by anyone on the network. Anyone can join the network and start validating transactions by running a node. A node is a computer that stores a copy of the blockchain and validates transactions. In a public blockchain, there is no central authority or organization that controls the network. The network is rewarded for keeping security and for the ongoing transactions being made on the network. Transactions are finite.

Examples of public blockchain include Bitcoin, Ethereum, Polygon, BASE and many more.

Private Blockchain

Private blockchain, on the other hand, is a closed network that is used by a specific group of individuals or organizations. Essentially it is a private database where transactions can be rolled back, edited or even deleted. Only authorized participants can join the network and validate transactions. The network is controlled by a central authority or organization, and transactions are hidden to participants in the transaction. They are mainly used by financial institutions who are entering the blockchain space and tokenizing their own assets for themselves or own network. They are still valuable but offer more of a zero to 0.1 value proposition, not a zero to one value change that public blockchains offer.

Public vs Private Blockchain

Now that we have a basic understanding of public and private blockchains let's compare them.

  1. Decentralization: One of the key differences between public and private blockchains is decentralization. Public blockchains are completely decentralized, meaning there is no central authority or organization that controls the network. On the other hand, private blockchains are centralized, meaning that there is a central authority or organization that controls the network.
  1. Transparency: Public blockchain are completely transparent, meaning that anyone can view all transactions on the network. On the other hand, private blockchains are not transparent, meaning that only authorized participants can view transactions.
  1. Security: Public blockchains are more secure than private blockchains. Because of its decentralized nature, it is much more difficult to hack or attack a public blockchain network. A private blockchain, on the other hand, is more vulnerable to attacks because it is centralized.
  1. Immutability: Public blockchains are immutable, meaning that once a transaction is added to the blockchain, it cannot be changed or deleted. This makes public blockchains an ideal platform for creating a tamper-proof ledger. Private blockchains can be tampered with, changed, rolled back and have its transactions even deleted.

Why We Believe Public Blockchains are Better

Public blockchains are better than private blockchains for several reasons.

Firstly and most importantly, every digital asset that matters is issued on a public blockchain (such as Bitcoin, Ethereum, 10,000+ alt coins, stablecoins, DAOs, NFTs and security tokens). Interoperability only works on public blockchains. The value of using blockchain is on public blockchains. You can only access and connect to the power of DeFi innovations on public blockchains.

Secondly, for those issuing real world asset tokens (asset backed tokens or security tokens, as they are commonly called), issuing your assets on public blockchains means you can start the first liquidity pools for your assets through IX Swap, the world’s first automated market maker for security tokens. You can see how it all works at IX Swap. This is the killer application for the security token industry bringing legal and compliant liquidity pools to any integrated digital asset.

Thirdly, public blockchains are decentralized. This makes it arguably more transparent and secure than private blockchains.

Fourthly, public blockchains are more inclusive. Anyone can participate in the network and validate transactions, regardless of their location or background. This makes it more democratic and fair than private blockchains which are only accessible to a select group of participants. 

Fifthly, public blockchains are more innovative. Because it is open-source and accessible to anyone, it is more likely to attract the best developers and entrepreneurs who can create new applications and use cases for the technology.

InvestaX and IX Swap, runs on the largest number of public blockchains in the industry, allowing for the greatest variety of choices for the digital issuance of assets. InvestaX has focused on public blockchains for years, because they are the most scalable and widely used infrastructure to issue security tokens and other digital assets. InvestaX remains agnostic to blockchains and continues to iterate and integrate with more and more exciting protocols, as the industry grows.

While private blockchains are an option and are compatible for certain businesses and products, they are inherently close-ended systems (Web 2.0) and although they improve efficiencies and transparency for an existing business, private blockchains cannot easily collaborate with other platforms and have no connection to any other digital assets including stablecoins, crypto assets, security tokens, NFTs, and DAOs (Web 3.0), therefore, limiting interoperability and scalability.

In summary, public blockchains have better technology infrastructure, which makes them more scalable, interoperable, and widely used. This is especially important for businesses that want to issue digital assets like security tokens, NFTs, and crypto assets. With public blockchains, businesses have the opportunity to participate in a larger network of users and assets, leading to greater opportunities for growth and innovation.
