It all started in October during the Global Financial Crisis in 2008 with Satoshi Nakamoto and his paper BitCoin: A Peer-to-Peer Electronic Cash System which addressed a key problem in electronic commerce:
A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution.
Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending.
We propose a solution to the double-spending problem using a peer-to-peer network.
Facebook says Libra would be tied to a basket of low-risk securities and traditional, government-issued currencies, such as the dollar, euro, pound and yen. Expected to be launched in 2020, Libra is described as a blockchain-based digital coin that will let Facebook users send and receive money or to pay for services. The goal is for Libra to be used outside of the social network as well: Consumers may eventually be able to use it to pay for a cab or a cup of morning coffee.
Enterprise grade permissioned distributed ledger platform that offers modularity and versatility for a broad set of industry use cases.

Kubernetes Cluster in the IBM Cloud
Blockchain IBP Pricing "** Preview the IBM Blockchain Platform at no charge for 30 days when you link your IBM Blockchain Platform service instance to an IBM Cloud Kubernetes free cluster. Performance will be limited by throughput, storage and functionality. IBM Cloud will delete your Kubernetes cluster after 30 days and you cannot migrate any nodes or data from a free cluster to a paid cluster. "

- The application uses Node.js and can sometimes get the wrong version of Node.
- If npm install gets errors,
- do: npm rebuild, npm install
- And if that doesn't work, do:
- nvm use 8.12.0 npm install or nvm use 8.12.0 npm rebuild npm install
- the same if npm start gets errors 1 You can also do the same if Visual Studio Code console, Local Fabric Ops pane, do Teardown and Restart Fabric Runtime
