Tradeoffs developers need to balance when building a dApp

The rise of blockchain dApps

DApps built on blockchain infrastructure are designed to hand control of data back to the users. However, it’s important for developers to remember that blockchain has some additional pain points that must be considered. Uriel Peled explains why it’s important to choose a foundation that will enable the dApp to evolve and sums up the dos and don’ts of decentralized applications.

Interview with Christopher Ferris, IBM Distinguished Engineer

“Hyperledger Fabric is now more accessible to developers who have already started working with Ethereum & its associated tools”

Hyperledger Fabric now supports Ethereum Virtual Machine (EVM) bytecode smart contracts. This popular blockchain framework is now more accessible to developers who have already started working with Ethereum and its associated tools. We talked to Christopher Ferris, IBM Distinguished Engineer about the implications of this step, what it means for Ethereum and blockchain developers & more.

Embark on your smart contract journey

Make sure your blockchain smart contracts are secure: OpenZeppelin 2.0 soars high

OpenZeppelin 2.0 is here, and this framework will help reduce your vulnerabilities. What’s new in this release? If you’re new to the world of building smart contracts or a seasoned veteran, where should you go from here? Time to see what’s under the hood in this new release (while we try very hard not to make Led Zeppelin references).

How to achieve it without sacrificing security and efficiency

Blockchain scalability for supply chains

How can we achieve a scalable blockchain-based supply chain solution without sacrificing security and efficiency? You’ll need a consensus algorithm that can quickly validate the transactions being made. In this article, Dr. Vlad Trifa explains why (and how!) a blockchain-based network designed to support global supply chains must be flexible, reliable, secure, and above all, scalable.

The missing protocol is ...

The Internet of Things: A technology in desperate need of a protocol

What is the missing protocol that will prove an essential companion to the internet of things and the data economy that comes with it? Blockchain, sort of. In this article, Henri Pihkala, CEO of Streamr discusses the demand for a real-time data economy and what’s needed to support the secure transport, storage and monetisation that the new data economy demands.

Security tips on writing smart contracts

Smart contracts work differently to what we’re used to, as they run and execute on the blockchain, not on your computer or smartphone, and this requires a change in thinking while writing code. Here are a few tips that should give you a clear idea of how to properly write smart contracts.

Exploring the boundaries of blockchain

IoT and blockchain: What are the possibilities?

IoT and blockchain may both be big buzz words right now, but can these two seemingly unrelated philosophies actually work together? In this article, Wilton Thornburg explains how IoT can take advantage of blockchain technologies.

Interview with Nate Ren, co-founder of Cypherium

“The shortcomings of current blockchain infrastructures are scalability & security”

Cypherium aims to be the most secure smart contract platform available. Why should you care? First, it’s the most versatile virtual machine on the market to date, according to co-founder Nate Ren. Second, the Cypherium Virtual Machine supports Java and is compatible with EVM. Let’s have a closer look at this platform and how it compares to other blockchain platforms like Hyperledger.
