Short Answer Questions

While HTTP focuses on transferring cryptocurrencies and tokens between and within blockchain networks, HTTP+ extends its functionality to include transactions with fiat banks and wallets.

In a client-server model, an HTTP client sends a request, such as a value transfer request, to an HTTP server. The server processes the request and interacts with the corresponding blockchain network to perform the transfer.

HTTP employs token-based authentication and two-factor authentication. Token-based authentication uses a token generated by the client and verified by the server, while two-factor authentication adds another layer of security, requiring the user to provide a second authentication factor.

HTTPS is a secure version of HTTP that uses SSL/TLS to establish an encrypted channel between the client and the server to ensure the confidentiality and integrity of the communication.

The "GET" command is used to retrieve information about an account, contract, transaction, or token exchange rate. For example, to retrieve the balance of an Ethereum address, you can use the following command: GET HTTP://ROOT_URL/ethereum/address/0x004E1A8B6d1B65C2497055e65AFC5E5A46Db750D/balance.

In HTTP's multi-signature transactions, multiple users are required to sign the transaction in order to execute. The HTTP server generates the original transaction and sends it to each signer for signing. Once the required signatures are collected, the server verifies the signatures and broadcasts the transaction to the blockchain network.

HTTP utilizes smart contracts to perform various security measures, such as verifying addresses, enforcing time limits and quantity limits, and filtering suspicious transactions.

Anchor tokens act as a bridge in cross-chain value transfer, providing a stable value store to facilitate seamless exchanges between different blockchain networks.

HTTP+ supports a variety of transactions between fiat accounts, fiat wallets, and blockchain networks, including fiat-to-token conversions, transfers between fiat accounts, and value transfers between different entity accounts.

Transaction aggregation in HTTP+ improves efficiency by grouping multiple transactions into a single blockchain transaction. This reduces transaction fees and optimizes cross-chain transfers by minimizing the need to convert network tokens into fiat currency.
