LineageEntry
LineageEntry in Seigr Ecosystem[edit]
LineageEntry is a fundamental component of Seigr's Lineage Tracking system, representing a single, immutable record of an action performed on a .seigr capsule. Each entry within a capsule’s lineage provides essential details such as contributor information, action type, timestamps, and hash references to prior states. LineageEntry ensures accountability and integrity by creating a verifiable historical log, allowing Seigr to track each capsule’s evolution over time.
Purpose of LineageEntry[edit]
The LineageEntry structure supports several core functions within Seigr’s decentralized data ecosystem:
- Action Accountability: Every significant action on a capsule—whether an update, replication, or rollback—is recorded, attributing it to a specific contributor or node.
- Data Integrity Verification: Each entry’s hash links it to the prior state, creating a continuous hash chain that preserves integrity across modifications.
- Transparency and Ethical Data Management: The recorded lineage entries provide an auditable history of actions, supporting Seigr’s ethical and transparent data principles.
- Support for Rollback and Adaptive Replication: LineageEntries log states that enable capsules to be restored to previous versions or replicated based on historical access and integrity needs.
Structure of LineageEntry[edit]
Each LineageEntry is a serialized record stored in a Protocol Buffer structure, defined in Seigr's lineage.proto file. Key components within each entry include:
- Action: A descriptor of the specific action taken (e.g., "update", "replication", "rollback"), providing context for the modification.
- Contributor ID: Unique identifier of the contributor or node responsible for the action, supporting traceability.
- Timestamp: ISO-formatted timestamp documenting when the action occurred, allowing Seigr to reconstruct the sequence of events.
- Previous Hashes: References to previous lineage entries, forming a hash chain that secures the entry’s integrity.
- Metadata: Additional information related to the action, including context such as replication parameters, access logs, or node-specific metadata.
Example of LineageEntry in Protocol Buffers[edit]
Each LineageEntry is defined as a message in the Protocol Buffers format, supporting efficient serialization and schema evolution:
message LineageEntry {
string action = 1;
string contributor_id = 2;
string timestamp = 3;
repeated string previous_hashes = 4;
map<string, string> metadata = 5;
}
This structure allows each entry to document its unique characteristics while maintaining a verifiable hash link to preceding entries, ensuring each capsule has an immutable historical record.
Key Components Explained[edit]
- Action: Defines the specific activity performed. This field is a required attribute that specifies the purpose of the entry, such as "creation", "replication", or "rollback".
- Contributor ID: The unique identifier of the contributor (or node) responsible for the action, ensuring accountability across decentralized nodes.
- Timestamp: Provides a precise record of when the action occurred, supporting the integrity and historical accuracy of lineage records.
- Previous Hashes: A list of hashes that connect the current entry to its predecessors, ensuring that each change is verifiable and forms an unbroken historical chain.
- Metadata: Optional additional data relevant to the action, such as node location, replication status, or other context-based information. This field supports flexible and adaptive data storage within the lineage record.
LineageEntry Process Flow[edit]
The creation and verification of a LineageEntry follow a structured flow, ensuring each entry remains secure, consistent, and verifiable within Seigr’s decentralized network.
1. Entry Initialization[edit]
When an action is taken on a capsule, a new LineageEntry is created to document the event. Initialization involves defining the action type, capturing contributor details, and setting a timestamp:
- Action Specification: The type of action is specified according to the event (e.g., “replication”, “rollback”).
- Contributor Attribution: The contributor ID is recorded, associating the action with a specific node or user.
- Timestamping: A precise timestamp is captured in ISO format, ensuring chronological traceability.
2. Hashing and Integrity Validation[edit]
Upon entry creation, a cryptographic hash is generated using HyphaCrypt to link the entry securely to the previous state. Each entry includes hashes to its predecessor(s), creating a secure chain of states:
- Hash Computation: A unique hash is calculated by concatenating the entry’s content with previous hashes.
- Integrity Verification: Before finalizing, each entry undergoes verification to ensure consistency and alignment with prior entries.
- Storage in Metadata: Once verified, the hash and associated data are stored in the entry’s metadata, enabling rapid future verification.
3. Serialization and Network Distribution[edit]
After hashing, each LineageEntry is serialized in Protocol Buffers format, allowing efficient network storage and transfer:
- Serialization for Network Efficiency: Protocol Buffers compress the entry for minimal storage overhead and fast transmission.
- Network Synchronization: Entries are distributed across nodes, ensuring that the updated lineage remains accessible and secure within Seigr’s distributed ledger.
4. Verification during Access and Replication[edit]
When accessed or replicated, each LineageEntry is validated using its hash chain to ensure no tampering has occurred:
- Hash Validation: The entry’s hash is recalculated and compared to the stored hash for consistency.
- Cross-Node Verification: Nodes cross-verify entries with other nodes in Seigr’s network to confirm data integrity.
- Historical Layer Validation: LineageEntries are verified against historical data layers (e.g., TemporalLayer) to confirm consistency over time.
Mathematical Model of LineageEntry Integrity[edit]
Each LineageEntry is part of a hash-linked sequence, ensuring continuity and security across all recorded actions. This structure follows a hash chain model:
1. Hash Linking Model[edit]
Given a sequence of actions , each action has an associated hash computed as:
where:
- represents the data content at action .
- is the hash of the previous entry, ensuring continuity and tamper resistance.
2. Probability of Compromised Lineage[edit]
The probability that a lineage remains uncompromised, , given entries and a probability of each hash remaining uncompromised, is defined as:
This probability model demonstrates the security of Seigr’s lineage tracking: as the number of entries increases, the probability of an intact lineage grows significantly, ensuring high resistance to tampering.
Integration with Seigr's Immune System[edit]
LineageEntry integrates with Seigr’s Immune System, supporting adaptive data replication, threat detection, and rollback capabilities:
- Threat Detection: The Immune System flags entries for high-risk actions and cross-validates with other nodes to identify compromised data.
- Rollback Triggers: LineageEntries provide historical states for capsules, enabling rollback to verified states if data integrity issues are detected.
- Replication Adaptation: High-demand or critical entries may prompt the Immune System to replicate the segment more frequently to enhance resilience.
Future Enhancements for LineageEntry[edit]
To further enhance data security and adaptability, Seigr plans future expansions for the LineageEntry framework:
- Predictive Access Pattern Analysis: Leveraging lineage data to anticipate high-demand segments, enabling preemptive scaling of replication levels.
- Decentralized Governance for Lineage Control: Allowing contributors within the network to influence replication, rollback, and lineage policies through community voting.
- Cross-Layer Validation: Expanding lineage validation across multiple network layers, enhancing security and accessibility in complex environments.
Benefits of LineageEntry in Seigr[edit]
LineageEntry offers the following benefits for Seigr’s data management:
- Immutable Historical Record: Ensures each action’s documentation is permanent and tamper-resistant.
- Enhanced Security and Accountability: The hash-linking model provides a secure structure for action tracking, ensuring contributors are accountable.
- Scalable and Resilient: The lineage system supports Seigr’s adaptive replication model, providing resilience in a dynamic, decentralized network.
Conclusion[edit]
