Experiments with IoT and Blockchain

Solidity is the most popular and de-facto programming language for developing smart contracts which run on the Ethereum network. Theoretically you can develop these smart contracts in other programming languages such as Serpent and LLL, however, the support for Solidity is far better. Solidity follows a syntax similar to javascript, however, it has its own set of keywords and data-types. I would recommend everyone to read the Solidity language documentation to understand the basics of the language. In this blog/tutorial, we will: Build a smart contract to implement the royalty payout scenario , I had described earlier. Compile this smart contract. Deploy the contract to the test network. Going forward in future tutorials, we will be re-using the same smart contract for the complete development. As with any programming language, there are numerous tools and frameworks that can be used for building an app. At times these can get too confusing and frustrating. I too had my ...

Most financial institutions in India evaluate an Individual for creditworthiness based on their CIBIL  score. However, no such creditworthiness scores are available for corporate. I believe a lot of time and effort is spent by many companies in researching on the financial health status of other companies they are dealing with before they can supply them with services/goods on credit. I haven't found any existing solution (at least in the Indian context) that provides the creditworthiness of a corporate. With the new tax regime GST, I believe there is a scope for a good product that can be built over blockchain that would evaluate the creditworthiness of a company. Probably prevent another Stayzilla? I am sure the same solution would find its application in other geographies too. I will update this blog with more details on the POC for this use-case that I am working in the weeks to come.
