Saelis terms
| Term | Definition |
|---|---|
| Saelis | The metaprotocol and its ecosystem. |
| Sigil | The individual protocol data unit: a structured, identifiable record published on Elysium and interpreted under Saelis rules. Plural: Sigils. |
| Piece | The conceptual role of a Sigil as a building block of something larger. |
| Envelope | The standard-independent part of a Sigil: protocol identifier, version, standard, metadata, references and body. |
| Body | The standard-specific content of a Sigil. |
| Reference | A directional relationship declared by one Sigil toward an earlier Sigil. Proposed. |
| Assembly | A logical composition of related Sigils, reconstructed by indexers. Proposed. |
| Standard | A ruleset that interprets a category of Sigils, such as ELC-20. |
| ELC-20 | The proposed fungible asset standard for Sigils. Draft. |
| Indexer | Software that discovers, orders and validates Sigils and computes derived state. |
| Transport | The mechanism used to publish Sigil records onchain. Undecided. |
| Position | A Sigil's place in canonical order: block number, transaction index and intra-transaction index. |
| Creator | The account that signed the transaction publishing a Sigil. |
| Holder | The account a standard considers to control a Sigil's state. |
| Candidate | A record that parses as an envelope but has not yet been validated. |
