Terminological Glossary and Definitions

Unique alphanumeric identifier on the Solana blockchain (public key), enabling the receipt, sending, or holding of digital assets.

Technical operation consisting of immutably recording a cryptographic fingerprint (hash) on a blockchain in order to establish proof of existence at a given date.

Secure development framework (Rust framework) used on Solana for the creation of smart contracts, integrating standardized security controls and a verifiable IDL.

Qualified technical or documentary contributors participating in the development, security, or documentation of the Trace & Anchor ecosystem, eligible for non-commercial allocations via the WCE wallet.

Distributed, shared, and immutable ledger enabling the recording of transactions in a decentralized manner. For the purposes of this document, this refers to the Solana blockchain.

Exceptional operation consisting of permanently removing token units from circulation. Burn is not used as an economic or deflationary mechanism within Trace & Anchor.

Provider of crypto-asset services within the meaning of Regulation (EU) 2023/1114 (MiCA). Delta Multimedia France declares that it does not provide any service falling within this qualification.

Management mode in which a third party holds or controls private keys on behalf of a user. Trace & Anchor is an exclusively non-custodial service.

Decentralized protocol enabling token exchanges via automated liquidity pools (AMM). Delta Multimedia France neither operates nor participates in any DEX.

Regulation (EU) 2022/2554 relating to digital operational resilience, certain principles of which inspire the project's continuity policy.

Regulation (EU) No 910/2014 on electronic identification and trust services, notably defining the evidentiary value of qualified timestamps.

Result of applying a cryptographic hashing function (SHA-256) to a file. The fingerprint is unique, irreversible, and does not allow reconstruction of the original content.

Logical unit of time on Solana (approximately 2 to 3 days), used for validator rotation.

Access modality to the service in which the user pays in fiat currency and delegates the technical execution of anchoring to Delta Multimedia France.

Technical cost paid to network validators for processing a transaction, expressed in SOL.

Moment of the initial deployment of the protocol and issuance of MLRCOIN-O tokens.

Irrevocable technical ceiling of the total number of MLRCOIN-O units that may be issued by the smart contract (10,500,000,000). It constitutes a technical capacity ceiling and not a valuation objective.

Architectural principle according to which only the cryptographic fingerprint is processed by the system; original files are never transmitted nor stored.

File publicly describing the structure, instructions, and parameters of a Solana program, ensuring functional transparency.

Minimum logical unit executed by a Solana program. A transaction may contain multiple instructions.

Identity verification procedure applied in the context of the pre-sale for compliance with anti-money laundering and counter-terrorist financing (AML-CFT) requirements.

Smallest divisible unit of the native SOL token (10^-9 SOL).

Technical optimization mechanism consisting of grouping multiple digital fingerprints into a single cryptographic structure (Merkle tree) in order to issue only one on-chain transaction.

Main production network of a blockchain on which transactions have real value.

Cryptographic data structure enabling the summarization of a dataset into a single root fingerprint (Merkle Root).

Unique address defining an SPL token on Solana, including its issuance rules.

Regulation (EU) 2023/1114 on markets in crypto-assets.

Machine participating in the Solana network, either as a validator or as an RPC access point.

Characteristic of a service in which the user retains exclusive control of their private keys.

Service providing external data to a blockchain. Trace & Anchor does not use any price oracle.

Solana address exclusively controlled by a smart contract, without a private key, used to manage secure logical states.

Cryptographic certificate attesting to the existence of a file or data at a given time.

Qualified Trust Service Provider within the meaning of the eIDAS Regulation.

Secret cryptographic information enabling a user to sign transactions. Its loss results in the definitive loss of access to the corresponding assets.

Solana mechanism requiring the temporary locking of SOL for on-chain data storage.

Interface enabling applications to communicate with the blockchain.

Sequence of 12 or 24 words enabling restoration of a wallet's private keys.

Minimum time unit on Solana (approximately 400 ms), corresponding to block production.

Executable code deployed on a blockchain defining the rules of a protocol.

Technical token standard on the Solana blockchain.

Public layer 1 blockchain using a Proof-of-Stake consensus combined with Proof-of-History.

Security delay imposed between the validation of a modification and its effectiveness.

Cryptographically signed operation modifying the state of the blockchain.

Crypto-asset intended exclusively to provide functional access to a specific service, without financial purpose within the meaning of MiCA.

Internal technical wallet dedicated to non-commercial allocations under the Anchoreurs Program.

Internal wallet containing undistributed MLRCOIN-O units.

Technical wallet of Delta Multimedia France used for SOL network fees.

Logical state indicating that an MLRCOIN-O unit is usable.

Logical state of temporary unavailability applied to a unit after use, for anti-abuse protection purposes.

Non-custodial wallet controlled by the user.
