Blockchain Selection for Tokenization Hinges on Control, Privacy, and Finality
When choosing a blockchain for tokenization, financial institutions must evaluate five key criteria. These include where issuer control resides in the stack, what controls actually permit, how the network handles privacy and disclosure, how long settlement takes to become final, and who validates transactions.
The order of evaluation matters, as most selection processes start with throughput and cost, which are less likely to constrain a regulated issuance. Controls can live in various layers of the stack, including token layer, smart contract standard, network configuration, or privacy architecture. The question to ask is whether the control would survive if the issuing contract were replaced.
The second criterion is understanding what controls actually permit and their trade-offs. Three capabilities matter for regulated issuances: freezing, recovery, and permanence. Freezing allows issuers to stop specific holders from transacting, while recovery enables them to reclaim assets. Permanence guarantees that certain actions cannot be reversed.
When it comes to privacy and disclosure, a public ledger can make every position and counterparty visible by default. The useful question is not how much privacy the network offers but who can see what and who can compel disclosure. Canton's model restricts what each party sees at sub-transaction level, while Solana approaches this problem differently with confidential transfers.
Settlement finality is a defined term that varies across networks. Deterministic finality means a transaction is final at a specific point, whereas probabilistic finality increases confidence over time but never reaches certainty. Institutions designing delivery-versus-payment flows need to know which type of finality their network offers.
The last criterion is understanding who validates transactions and what it takes to become one of them. Validator structure decides both censorship resistance and operational trust models. Canton uses proof-of-stakeholder consensus, while Avalanche lets each L1 operator choose its own validator set with permissioning available against KYC and KYB standards.
The choice of blockchain for tokenization is not just about technical specifications but also about the underlying trust models and control structures.
