（1） In existing approaches, changes to multisig members or approval thresholds, as well as recovery in the event of key loss, require manual coordination among multiple parties and can be cumbersome. Datachain, however, enables these processes to be handled flexibly and with ease.

⚫︎ Why Privacy Matters Now?

In every business transaction, privacy has always been a given. As finance moves on-chain, preserving that expectation is no longer automatic. It must be deliberately built.

Protecting anonymity, confidentiality, and unlinkability while still meeting institutional requirements for governance and auditability is the foundation of the next generation of financial infrastructure.

Privacy

The Privacy Requirements for Institutions

Institutional grade privacy requires all three. Anything less leaves critical data visible to anyone.

Anonymity

Protects sender and receiver

Confidentiality

Protects asset and amount

Unlinkability

Protects relationships and patterns

What does it mean for anonymity and confidentiality to be guaranteed?

A state of nothingness

Only anonymity is hidden (hiding "who sent it")

Only confidentiality is hidden (hiding "balance and transaction amount")

Hiding both anonymity and confidentiality

What does it mean for unlinkability to also be guaranteed?

There is no unlinkability protection.

If the relationships of transactions are analyzed, privacy such as who sent it can be deduced.

Unlinkability available.

Connections disappear, and only something unrelated and isolated can be observed.

Operational flexibility for enterprise use

Selective disclosure

Share transaction data only with authorized parties to satisfy audit requests from regulators and financial institutions, without exposing it publicly.

Flexible key recovery options

Ensure seamless business continuity even during role changes or handovers

Enterprise-grade key management

Support for passkeys and HSM based signing to meet institutional security requirements.
