Physical Preservation
Encapsulation
Techniques such as silica encapsulation or lyophilization protect against
moisture, oxidation, and temperature fluctuations. In this state, DNA can
remain intact for centuries.
Inert at rest
Preserved DNA requires no active power, no cooling, and no periodic refresh
cycles. It is stable until explicitly accessed.
Sample Management
A DNA archive is organized as a collection of vials or microtubes, each containing millions of identical molecules.- Redundant copies can be created from the same writing process
- Distributed storage across multiple facilities provides disaster recovery
- Independent verification is possible from any copy without affecting others
Retrieval Readiness
Although DNA archives are inert, they remain immediately accessible. A sample can be hydrated and processed for sequencing at any time. Specific subsets of identifiers can be selectively retrieved making large-scale collections more practical to use than tape or disk-based archives, which often require full sequential scans.Role of Operators
In the xDNA Labs network, specialized facilities act as custodians of DNA
archives. Their responsibility is to safeguard physical samples and provide
verifiable access when queries are made. On-chain proofs ensure that stored
datasets can always be matched against their original digital commitments.
