Use a Transparent and Secure Public Blockchain without Cryptocurrency

The world's only public blockchain without cryptocurrency, InfraBlockchain, has proven its capacity and usability through the blockchain-based vaccine passport COOV, which has more than 43 million users and successfully brought in participation from government agencies and large corporations.

Enterprise Multi-Blockchain Network without Cryptocurrency

Government agencies and enterprises can build and operate blockchains specialized for various services in parallel. Each blockchain is connected to the Infra Relay Chain, which serves as a hub between different blockchains, and interoperates with other blockchains to achieve extreme scalability.

Infra Relay Chain is a public blockchain without cryptocurrency. Infra Relay Chain enables government agencies and trusted companies to participate in the blockchain ecosystem, thanks to the Proof-of-Transaction(PoT) consensus mechanism. InfraBlockchain technology empowers the implementation of InfraBlockspace, a multi-blockchain network that can encompass various blockchains.

Federated Multi-Blockchain

Individual Multi-Blockchains ecosystems can be interlinked to establish a more extensive system. This network eventually scales into a Federated Multi-Blockchain structure where numerous multi-chains are interconnected.

Current Challenges

Challenges with
Current Blockchain Technology

Issues with Cryptocurrency

Cryptocurrencies are used as transaction fees for using public blockchains. To utilize public blockchains, blockchain service providers and users must acquire and spend cryptocurrency from exchanges. The significant price volatility of these cryptocurrencies and regulatory constraints complicate accounting practices for companies. Consequently, government entities and businesses face challenges when trying to adopt cryptocurrency-based public blockchains.

Limitations of Private Blockchains

A private blockchain is a restricted system operated exclusively by authorized participants. While organizations and businesses that struggle with adopting public blockchains have considered private alternatives, they often confront security issues. Given their limited participant involvement, private blockchains tend to offer lower security and struggle to ensure trust. Their closed-off structure makes it tough to onboard a large number of network participants and users, leading to heightened costs when attempting to scale the blockchain network.

Shortcomings of Single Blockchains

Most established blockchain networks function based on solitary, independent protocols. However, these singular blockchain networks(mainnets) have inherent limitations in processing speed and capacity. This makes operating a global-scale blockchain service using only one blockchain quite challenging. Interoperability becomes particularly problematic between multiple blockchain applications constructed with different protocols and cryptocurrencies.

InfraBlockchain :
Crypto-less Public Multi-Blockchain Technology

Why InfraBlockchain?

Constructed in partnership with government agencies and multinational corporations, drawing parallels to the frameworks of electricity grids and road networks, InfraBlockchain is designed as a blockchain network for societal infrastructure. Not only government entities and businesses, but essentially everyone will benefit from it. This technology enables the construction of highly scalable multi-blockchain networks, interoperable under a singular protocol, and the realization of large-scale global blockchain services, all without issuing cryptocurrency.


Cryptocurrency-less Blockchain Network

Trusted entities such as government agencies and companies can actively participate in the blockchain network, establishing a public infrastructure-oriented blockchain ecosystem without cryptocurrency. The transaction fees required for the operation of these public blockchains can be covered using Stable Tokens, backed by legal currency guaranteed by these trusted entities. Moreover, through consensus agreements within the blockchain network, certain trusted service providers and users can access and utilize the blockchain without incurring transaction fees.


Public Blockchain Technology

A public blockchain should be accessible to all and must enable the election of representative groups, known as validators, with the rights to create blocks and partake in network decision-making. InfraBlockchain uses a unique Proof-of-Transaction consensus algorithm. This method utilizes blockchain transactions as votes, allowing credible service providers to be chosen as representatives. Such an approach facilitates the creation of a public blockchain where anyone can participate under fair and reasonable terms, without the need for using cryptocurrency.


Multi-Blockchain Technology

InfraBlockchain shows remarkable scalability and interoperability by interlinking multiple service blockchains that run concurrently. These are tethered to the Infra Relay Chain, which functions as a hub among blockchains. This multi-blockchain technique transcends the constraints of traditional single blockchains, paving the way for substantial global expansions. Participants from diverse industries and geographies can convene to set up their distinct independent Multi-Blockchain Networks. This offers limitless scalability that morphs into a Federated Multi-Blockchain structure.
