Secured By Chainlink
Secured By Chainlink

Chainlink is an open-source framework for creating decentralized blockchain oracles, which bring off-chain data on-chain. The open-source nature of this framework means anyone can contribute to the code base and one way you can contribute is by creating an “external adapter”. What is an external adapter? You can think of an external adapter as code (more specifically an API server) that sits between a data source and a Chainlink node. …

*Update 08/16/20: As this article has gotten a fair amount of attention I would like to update it with some new information. One is I have become an official Chainlink Advocate since 11/2019. Also Sergey has addressed why this type of design (dubbed “Security by Obscurity”) is not ideal for the blockchain oracle problem which can be seen in this talk (specifically around 18:00). I agree with him and not just because I am now an advocate, and felt it was important to disclose everything. Also Chainlink has released their own VRF which can be used to securely generate randomness…

As a blockchain enthusiast that has tried to explain the benefits of blockchain and smart contracts many times; there’s a lot to explain. Decentralized protocols are complicated and confusing so why not just rely on centralized business models? Please note, when referring to decentralization, I am referring to political and architectural decentralization.

In this article I will provide an argument on the inherent value of blockchain and decentralized organizations due to: automatic execution of agreements, unprecedented competition, transparency, increased operational efficiency, and enormous network effects. Finally I will discuss some common counterpoints to decentralized organizations. As always, I welcome critical…

One of the biggest innovations of Bitcoin was the use of the, now well known, Proof-of-Work (PoW) consensus algorithm. A consensus algorithm is what allows different nodes in a distributed network to come to an agreement on the state of the system (blockchain in this case) despite not knowing or trusting each other. Since the advent of Bitcoin and PoW, there has been an explosion of different consensus algorithms, each with their own trade-offs.

I plan on creating a series of articles going into detail on some of the biggest blockchains and their various tradeoffs including their consensus algorithms. Before…
