A computer-implemented method for testing blockchain applications, the method being executed by one or more processors, the method comprising: instantiating a test blockchain container having read-only access to a production blockchain ; and executing a test of a blockchain application based on at least a portion of the production blockchain, the executing comprising i) copying , by the test blockchain container, a set of blocks (0001-0004) from the production blockchain to a test environment to provide a test blockchain , the test blockchain container having read-write access to the test blockchain, and ii) executing, by the test blockchain container, one or more test operations, wherein executing the one or more test operations generates a set of test blocks (0005-0008) that are sequentially appended to the test blockchain, each test block at least partially comprising test data , wherein during execution of the test of the blockchain application, i) production blocks are appended to the production blockchain, and ii) the production blockchain and the test blockchain are executed in parallel and independent of one another, wherein the test blockchain is modified without affecting the production blockchain and the production blockchain is modified without affecting the test blockchain. instantiating a test blockchain container having read-only access to a production blockchain ; and executing a test of a blockchain application based on at least a portion of the production blockchain, the executing comprising i) copying , by the test blockchain container, a set of blocks (0001-0004) from the production blockchain to a test environment to provide a test blockchain , the test blockchain container having read-write access to the test blockchain, and ii) executing, by the test blockchain container, one or more test operations, wherein executing the one or more test operations generates a set of test blocks (0005-0008) that are sequentially appended to the test blockchain, each test block at least partially comprising test data , i) copying , by the test blockchain container, a set of blocks (0001-0004) from the production blockchain to a test environment to provide a test blockchain , the test blockchain container having read-write access to the test blockchain, and ii) executing, by the test blockchain container, one or more test operations, wherein executing the one or more test operations generates a set of test blocks (0005-0008) that are sequentially appended to the test blockchain, each test block at least partially comprising test data , wherein during execution of the test of the blockchain application, i) production blocks are appended to the production blockchain, and ii) the production blockchain and the test blockchain are executed in parallel and independent of one another, wherein the test blockchain is modified without affecting the production blockchain and the production blockchain is modified without affecting the test blockchain. i) production blocks are appended to the production blockchain, and ii) the production blockchain and the test blockchain are executed in parallel and independent of one another, wherein the test blockchain is modified without affecting the production blockchain and the production blockchain is modified without affecting the test blockchain. <EOS>
