The architecture of a blockchain network is a critical determinant of its suitability for different applications, and the market is broadly segmented by these platform types. A market-level analysis of the Blockchain Market shows a clear distinction between public, private, and consortium blockchains, each offering a different balance of decentralization, performance, and privacy. Public blockchains, such as Bitcoin and Ethereum, are permissionless, meaning anyone can join the network, participate in the consensus process, and view the transaction ledger. This radical transparency and censorship resistance make them ideal for applications like cryptocurrencies and public voting systems. However, their open nature often comes with challenges related to scalability (transaction speed) and a lack of privacy, which can be a significant barrier for enterprise adoption where confidential business data is involved. These platforms have been instrumental in driving innovation and demonstrating the core concepts of the technology to a global audience.

In response to the limitations of public blockchains for corporate use, private and consortium blockchains have emerged as the dominant models for enterprise applications. Private blockchains, also known as permissioned blockchains, are controlled by a single organization. This central entity determines who can participate in the network, who can view the data, and who can validate transactions. This centralized control allows for much higher transaction speeds, greater scalability, and the ability to maintain data confidentiality, which are critical requirements for businesses. A prime example of a platform used for private deployments is Hyperledger Fabric. The Blockchain Market size is projected to grow USD 163.2 Billion by 2035, exhibiting a CAGR of 31.66% during the forecast period 2025-2035. This model is well-suited for internal use cases within a single company, such as managing internal records or streamlining intra-company workflows, where the benefits of immutability and efficiency are desired without full decentralization.

Consortium blockchains represent a hybrid model that strikes a balance between the full decentralization of public chains and the single-entity control of private chains. In a consortium, the network is governed by a pre-selected group of organizations. This model is ideal for collaboration between multiple companies within the same industry, such as a group of banks collaborating on a trade finance platform or a consortium of food producers and retailers building a supply chain tracking network. Platforms like R3's Corda and Hyperledger Fabric are widely used for building these industry-specific consortiums. This approach allows participating organizations to benefit from a shared, trusted ledger while maintaining control over data access and governance within a known and trusted group. The growth of consortium blockchains is a key indicator of the market's maturation, as it signals a move from single-company experiments to industry-wide collaboration, which is where blockchain's network effects can be most powerfully realized.
