What the native network does

Datachain Rope operates differently than traditional block-based ledgers. It replaces the standard block and chain terminology with knots, strings, and cords.

In this system, every entity, such as a wallet or a smart contract, owns its own sovereign micro-ledger called a string. Events on that string are recorded as individually addressable knots. This structure allows for cryptographic tombstoning through the rope_untieKnot function, which enables the erasure of specific event entries to satisfy GDPR Article 17 requirements.

The network uses Testimony Consensus. Knot witnesses anchor knots to the federation cord approximately every 4.2 seconds. The network also uses hybrid post-quantum signatures, including Ed25519 and Dilithium3 for signing, and X25519 and Kyber768 for key exchange.

Anchor-knot rewards are distributed as follows:

• Knot proposer: 30%
• Testimony pool: 45%
• Node operators: 20%
• Federation and community: 5%

Our database does not show FAT as a token on other platforms. You must verify which withdrawal network your exchange supports before attempting a transfer. You can find more technical details in the official documentation or inspect the source code.

Self-custody and withdrawal risks

Deposit and withdrawal support for the listed exchanges is not verified. You should check the exchange interface for current support before depositing funds.

There are several risks to consider when handling FAT:

• Exchange availability, KYC requirements, and account features vary by country.
• Not all exchanges that list a token support deposits and withdrawals on the same network.
• Transferring tokens to an unsupported network or the wrong chainId can result in permanent loss.
