ConnectionChain

(1) The Provided Functions

Fujitsu provides its proprietary blockchain integration technology that securely connects two or more independently operated systems (blockchains or web APIs) to manage ledgers that ensure the evidentiality of transactions. Specifically, Fujitsu provides a sample application (with downloadable source code) and user manual (API specifications and sample application manual) that focuses on environmental value transactions using web APIs, and supports the integration of Fujitsu Data eTRUST and Ethereum testnet (Sepolia).

(List of other systems that can be used in conjunction)

In addition to the free version of Fujitsu Data e-TRUST and Ethereum testnet (Sepolia), general systems and applications provided by users or third parties can also be used.

(2) Restrictions
  1. Users are prohibited from using the Provided Function for cryptographic assets or similar assets defined in Article 2, Paragraph 14 of the Payment Services Act.
  2. Users must use the Scenario Execution API with an interval of about 5 seconds (however, execution may be restricted for more than 5 seconds depending on the execution status of other users). In addition, the maximum number of API requests per ID per day is 40.
  3. For the use of the sample application (including the Scenario Exection API call used in the sample application), token issuance and token offset must be executed at an interval of about 5 seconds, and the maximum number of requests per ID per day is 40. The maximum number of tokens that can be issued and offset per ID per month is 40. Also, the Users shall not execute if the GasPrice on the Sepolia testnet exceeds 200 Gwei (refer to the figure of https://sepolia.beaconcha.in/gasnow, etc.).
  4. The User shall not use the data that includes confidential information and/or personal information, such as secret keys and/or personal passwords used in the blockchain to be integrated (the User shall create a new account for the integrated blockchain for experimental use).
  5. The User is responsible for the transaction fees (Sepolia ETH currency in Ethereum testnet (Sepolia)) for executing smart contracts and transactions on the integrated blockchain, and Fujitsu is not responsible for the fee burden.
  6. Fujitsu is not responsible for the impact on external applications and/or Users caused by the transaction execution results and/or execution of transactions (including malfunction of the ConnectionChain).
  7. The addition of integrated systems or blockchains including the paid version of Fujitsu Data e-TRUST and Ethereum mainnet (such as restricting integration to specific users) is not implemented under this Terms of Use and will be separately determined.
  8. Fujitsu is not responsible for the impact of restarting or stopping the ConnectionChain or deleting data during irregular periods (such as during maintenance or system failure).
