Motivated by the recent explosion of interest around blockchains, we examine whether they make a good fit for the Internet of Things (IoT) sector. Blockchains allow us to have a distributed peer-to-peer network where non-trusting members can interact with each other without a trusted intermediary, in a verifiable manner. We review how this mechanism works and also look into smart contracts-scripts that reside on the…

Bitcoin is starting to come into its own as a digital currency, but the blockchain technology behind it could prove to be much more significant. This book takes you beyond the currency (Blockchain 1.0) and smart contracts (Blockchain 2.0) to demonstrate how the blockchain is in position to become the fifth disruptive computing paradigm after mainframes, PCs, the Internet, and mobile/social networking.

Blockchains are tamper evident and tamper resistant digital ledgers\nimplemented in a distributed fashion (i.e., without a central repository) and\nusually without a central authority (i.e., a bank, company, or government). At\ntheir basic level, they enable a community of users to record transactions in a\nshared ledger within that community, such that under normal operation of the\nblockchain network no transaction…
