The Business blockchain by William Mougayar is a good primer for understanding the potential impact of the block chain and a fantastic insight into the future applications of blockchain technology.
The intro, by Ethereum's founder, Vitalik Buterin, did a very good job at setting the picture up of how the blockchain is an inevitable byproduct of the times, created by a need for trust. William Mougayar does not go into specific short term ways of teaching you how to create value via the blockchain as much as lay a framework how we will use the blockchain in ways none of us are even imagining today.
Blockchains are new technology layers that rewire the Internet and threaten to side-step older legacy constructs and centrally served businesses. At its core, a blockchain injects trust into the network, cutting off some intermediaries from serving that function and creatively disrupting how they operate. Metaphorically, blockchains are the ultimate non-stop computers. Once launched, they never go down, and offer an incredible amount of resiliency, making them dependable and attractive for running a new generation of decentralized services and software applications.
The Business Blockchain charts new territory in advancing our understanding of the blockchain by unpacking its elements like no other before. William Mougayar anticipates a future that consists of thousands, if not millions of blockchains that will enable not only frictionless value exchange, but also a new flow of value, redefining roles, relationships, power, and governance. In this book, Mougayar makes two other strategic assertions. First, the blockchain has polymorphic characteristics; its application will result in a multiplicity of effects. Second, we shouldn't ask ourselves what problems the blockchain solves, because that gives us a narrow view on its potential. Rather, we should imagine new opportunities, and tackle even more ambitious problems that cross organizational, regulatory and mental boundaries.
Drawing on 34 years of technology industry experience as an executive, analyst, consultant, entrepreneur, startup mentor, author, blogger, educator, thought leader, and investor, William Mougayar describes a future that is influenced by fundamental shifts brought by blockchain technology as the catalyst for change. William Mougayar has been described as the most sophisticated blockchain business thinker. He is a blockchain industry insider whose work has already shaped and influenced the understanding of blockchain for people around the world via his generous blogging and rigorous research insights. He is a direct participant in the crypto-technology market, working alongside startups, entrepreneurs, pioneers, leaders, innovators, creators, enterprise executives, and practitioners; in addition to being an investor, advisor, and board member in some of the leading organizations in this space, such as the Ethereum Foundation, OpenBazaar, and Coin Center.

Even though everyone is talking about smart contracts and their advantages over traditional paper contracts, only a handful of people are addressing the elephant in the room: most of the businesses don’t know how to use smart contracts yet. Jincor is among those few who are trying to make smart contracts and other blockchain technologies more accessible to modern businesses. And anyone can chime in by joining the project’s public token sale, which starts today, on the 1st of December.
Jincor is a secure, regulatory compliant, and easy-to-use platform that allows businesses to work with smart contracts and cryptocurrency payments with no legal, technical, or operational complications, in a cost-efficient manner.
As was mentioned in Forbes, leading technology providers like IBM and Microsoftare offering blockchain solutions to enterprise clients. Tech start-ups too are aggressively capitalizing on the boom by building new products and services that depend on the technology. This year alone, blockchain startups amassed more than $3.25 billion in funding through token sales.
For other businesses, however, the big question is how blockchain adoption can benefit them. There is no question that modern business environments require companies to make technology integral to their strategy. But stil, business owners are often struggles with that due to blockchain solutions complexity and high price tags. And that’s the problem that Jincor’s team is trying to solve.
The project investment potential was estimated as high by ICORATING, rating agency for ICO market. Among notable advisors are Michael Terpin, chairman, and co-founder of BitAngels, and Jason King, co-founder of Unsung.org and School for blockchain development – Academy.
So far, Jincor has successfully launched a closed beta testing its basic functionality – set of features for secure and efficient enterprise interactions – in cooperation with dozens of companies, and the open beta release that will become available at the beginning of December had already attracted 300+ businesses to give it a try. In open beta, there will be much more features available, including cryptocurrency wallets, built on pre-alpha version of Jincor’s private blockchain, and basic labor smart contract template, that can be easily customized for the needs of businesses of any industry and scale.
By the end of 2018, Jincor expects to have over 10,000 business customers in open beta and develop mobile apps for iOS and Android. Registering at Jincor.com and evaluating the advantages of Jincor’s ecosystem is free of charge for any business. However, if companies want to use digital verification, smart contracts, arbitrage system and other features of the platform, they will be charged in JCR tokens, as it will be a store of value, the sole means of paying transaction fees, and the mean of fueling smart contracts of Jincor protocol. There will be no additional emission of JCR tokens in the future but the demand, most likely, will continue to grow in geometrical progression.
The company has put on sale 76% of its JCR tokens, which will be an integral part of Jincor platform. The token price is $1 per 1 JCR; the ETH/JCR exchange rate is calculated automatically in accordance with the current ETH/USD rate. Earlier in August startup held pre-ICO campaign, selling 4% of JCR tokens emission, and reaching the hard cap in less than a week. The token sale starts on the 1st of December, and will last until January 31, 2018, or until all the allocated tokens are sold, and the hard cap of $26.6 mln is reached (the soft cap is $2.5 mln).

Here are the list of tips and tricks to develop solidity in a modern way (understand back to 2017 year :-) )
- Intellij-Solidity see https://github.com/intellij-solidity/intellij-solidity
- Solidity Solhint Plugin allow to enable Solhint inspection capabilities in your project. It highlight of warnings / errors found by the linter in editor during code modification.
Auto-completion of solidity
Your smart contract code also deserve to be recognized by your IDE and in your test-cases. In order to enjoy auto-completion you'll have to use Soltsice ()https://github.com/dbrainio/Soltsice) to convert Solidity code to TypeScript at compile time.
Add to your package.json
"types": "soltsice build/contracts types",
mocha, jasmine, chai, chai-as-promised, babel-core, add as much as your are using in your code.
FYI by doing so you just add typedscript packages from DefinitelyTyped GitHub project.
Auto-completion of Web3
There currently no official Web3 type definition included in the DefinitelyTyped project. But there is one package good enough even if in Beta at https://www.npmjs.com/package/web3-typescript-typings
Only the Truffle debugger for now http://truffleframework.com/docs/getting_started/debugging
Running unit test
CI in Travis with Docker, .travis.yml
dist: trusty sudo: required group: beta language: node_js node_js: - "8" cache: directories: - node_modules before_script: - truffle version script: - npm run lint - npm run test notifications: slack: rooms: - secure: xxxxxxxxxxxxxxxx on_success: change on_failure: always on_pull_requests: false
Easy testing of EVM Time shifting with Truffle snapshot/restore
Buggy right now, but may be solved soon see https://github.com/trufflesuite/ganache-cli/issues/390
This is a work in progress, i will continue trying to improve my day to day Solidity toolbox! If you have more tips, feel free to use the comment section below.
