Short Answer Questions

A redemption script is a script that contains the conditions required to unlock a token. When a user wants to use or transfer the cryptocurrency associated with a token, they need to provide an unlocking script that satisfies the redemption script conditions. The redemption script contains metadata, public keys, and other conditions that are used to control the transaction of the token.

Metadata stores information about a token, such as its type, value, and associated terms. It is embedded into the redeem script, which is hashed and stored on the blockchain. This approach allows for secure, transparent recording and verification of token information without having to store all data on the blockchain.

The three main transaction types are create tokens, redeem tokens, and transfer tokens. Creating a token involves converting fiat currency or other assets into a tokenized form. Redeeming a token allows users to redeem tokens back to their original assets. Token transfers enable users to send and receive tokens between each other.

The peg determines the value of a token relative to the underlying cryptocurrency. For example, if the peg is 100 satoshis per token, a transaction output worth 10,000 satoshis would represent 100 tokens. The peg allows for flexibility in tokenizing different types of assets and values.

An issuance transaction is a transaction in which the issuer creates a new token and allocates it to a user. This transaction includes sending the cryptocurrency pegged to the token to the user address, as well as creating a redemption script containing the token metadata and associated public keys.

User private keys can be secured in a number of ways. Ideally, user private keys are stored in a secure wallet controlled by the user and are never shared with the issuer. In some cases, a multi-signature scheme may be used, where both the issuer and the user’s signatures are required to authorize a transaction.

Involving an issuer in a token transfer helps prevent double spending and ensures that the token is used only according to the token’s terms and conditions. The issuer acts as a trusted intermediary, validating transactions and updating records associated with the token.

The minimum threshold refers to the smallest amount of cryptocurrency that can be associated with a token. This threshold is set to prevent the creation of too-small transaction outputs (known as “dust”), which could clog up the blockchain network.

Minimizing transaction fees is critical in tokenized systems, as frequent token transactions can result in large fees. By using efficient scripts and transaction structures, these costs can be reduced, making tokenized systems more practical and cost-effective.

Divisible tokens can be divided into smaller units, while indivisible tokens can only be transferred as a whole. For example, tokens representing fiat currencies are often divisible, while tokens representing unique assets (such as tickets or artwork) are often indivisible.
