To interface with a blockchain from an existing system mainframe or other , businesses either need to create APIs through a software developer kit or locate an existing API to communicate with the blockchain and record transactional data as agreed upon within the peer network. You sink that much investment into a mainframe, you're going to be having better things to do with them than mine bitcoin. Sometimes if we were lucky it came with carbon paper! You could ride the frenzy and hope to get out in time, or you could invest in a leading company using the blockchain technology that underlies cryptocurrencies like bitcoin for real-world applications.
According to Gartner, Blockchain passed from peak Hype Cycle to the Trough of Disillusionment in August of , but they are still bullish. Despite the drop-off, Gartner makes the point that the hype was not misplaced. One report says that the majority of Fortune Companies are pursuing blockchain initiatives, so while the hype is down, projects are up. Use cases include payments, supply chain, logistics, healthcare, food safety, and smart contracts.
We need to remember that these use cases are not complete solutions, they are merely applications of blockchain to execute transactions and store the results on a distributed ledger.
Why IBM Wants to Marry Your Blockchain and Your Mainframe
Transforming them into true solutions requires integration with existing legacy systems. For example, if a bank wishes to track Bitcoin holdings for customers, the legacy systems need to pull data from the Bitcoin ledger. If they want to execute transactions, it becomes even more complicated.

In addition, hosting a blockchain on a mainframe allows organizations to take advantage of the tremendous computing power offered by mainframe systems. That is also important in this context because compute-intensive tasks, such as cryptographic hashing, are often an important part of blockchain use cases.
Since commodity servers are not always up to this challenge, mainframes could help close an important infrastructure gap for companies seeking to build their own blockchains.
That is a big difference between the types that organizations might host on Z systems and those that run publicly. IBM is catering to exactly this type of customer. Thousands of organizations around the world continue to rely on mainframes for mission-critical business applications.

There are many systems and networks that depend upon one another to support a single business Christopher Tozzi February 13, Share on: LinkedIn Twitter Facebook. What is blockchain? System administrators cannot access the memory or processor state; there is no direct host or OS level interaction. By using a TEE, one does not have to trust the host system which runs the blockchain node.
With only a portion of the application secured by SGX, neighbouring applications can attack the SGX application with a side-channel attack, which has been done successfully. When the enclave stops, restarts, or crashes, the internal state is lost and cannot be recovered. SGX uses a data sealing approach that encrypts and authenticates data before leaving the enclave where it is stored externally. When the enclave restarts, it loads and decrypts the data preserving data confidentiality.
How Bitcoin mining works
However, it does not prevent rollback attacks whereby properly sealed data operates on blockchain state data that could be stale. Rollback attacks on stateful applications running in TEEs pose serious risks, unless the state continuity of an application is ensured. For example, if a malicious blockchain node is able to influence the execution order of smart contract transactions in an SGX enclave, it could learn information about those transactions without being able to decrypt them.
The node running a sealed-bid auction blockchain application could execute a bid evaluation transaction multiple times and then reset the enclave again afterwards every time a new bid has been committed to the ledger.
Blockchain on IBM Z offers exceptional security, speed and integration with the transactional data already on the mainframe. use cases involving blockchain on mainframe computers, and IBM is blockchain, we are not just thinking about bitcoin and cryptocurrency.
Thus, the malicious node could make inferences about other bids violating the integrity of the system without having to break encryption in the SGX enclave. The SGX architecture is also vulnerable to state continuity exploits. Since the malicious node has access to the key value store database, that cannot be accommodated by the SGX enclave due to size limitations, the node could intercept, modify, reorder, discard, or replay smart contract operations by feeding the enclave manipulated state inputs or even drop messages or halt the enclave and prevent consensus altogether.
State continuity and rollback attacks can be prevented if the state input to the smart contract enclave always corresponds to the unique, committed blockchain state.
Docker Content Trust is commonly used to make sure that a container binary image is from an original developer, not from a malicious developer. If signing the key were to be stolen, a malicious person could replace the image on Docker Hub with another image with malicious code.
Forget Bitcoin: Buy This Blockchain Stock Instead
Third party auditors perform code reviews and testing prior to deployment to ensure the integrity of the build. Auditors review the manifest that describes all the ingredients to produce the image binary, such as the source code, and a base image, and so on. Each auditor checks the manifest to establish confidence that no malicious code exists in the final image.
The attested image is deployed into the LinuxONE SSC runtime environment by build endorsement service via an endorsement policy, like a multi-signature or multi-factor authentication. LinuxONE SSC only runs a Docker container if the image is trusted in the Docker content trust framework and if the manifest meets an endorsement policy for this particular application.
