Public vs. Private Blockchains: Which Rail Suits Real-World Asset Tokenisation?
Deciding between a public or permissioned network is one of the earliest calls in any issuance. Far from being a purely technical debate, it directly governs liquidity, commercial confidentiality, and investor confidence.
When a company decides to tokenise an asset, one of the first questions around the boardroom table concerns the underlying blockchain network. Grasping the distinction between public and private (or permissioned) infrastructure is critical, as it dictates who can audit transactions, how freely tokens circulate, and how much credibility the instrument commands in the market.
Public blockchains: verifiable transparency These are open, decentralised networks—such as Ethereum, Polygon, or the XRP Ledger—where no single entity controls the ledger unilaterally. Any participant can independently verify issuance history, asset provenance, and smart contract rules in real time. For the RWA market, this provides an unmatched guarantee: investors need not rely blindly on issuer spreadsheets when the audit trail is public, permanent, and tamper-proof.
Private or permissioned blockchains: closed control These networks are governed by a consortium or central administrator that dictates who can run nodes, validate transactions, and view ledger data (for example, Hyperledger Fabric or R3 Corda). While they offer tight control over data visibility and high internal throughput, they sacrifice open auditability and seamless interoperability with global capital markets.
Which is best suited to real-world assets? The decision rests on balancing three core factors:
- Investor profile: Institutional and cross-border capital demands independent verifiability. The less an investor has to trust the operator's internal reporting, the lower the perceived risk—and the tighter the pricing you achieve.
- Regulatory perimeter: Modern regimes—such as Argentina's CNV framework—explicitly accommodate public blockchains, provided robust compliance and identity controls are embedded at the smart-contract layer.
- Commercial confidentiality: No corporate wants sensitive counterparty terms or proprietary pricing exposed on a public block explorer. Today, this is solved through hybrid architectures: a public chain anchors token integrity and ownership, paired with cryptographic privacy layers (such as zero-knowledge proofs) that shield commercially sensitive data.
Global market direction is unmistakable: the assets attracting the deepest pools of liquidity are those issued on auditable public networks, wrapped in institutional-grade privacy and compliance standards.
