Using MerkleTree for Blockchainized Document Certification
As a freelance I worked on document certification using blockchain. I received several similar requests, but one of them required the implementation of a new data structure: Merkle Trees.
Ethereum Use Case: Document Certification
As a freelance, I worked on documents certification using the Blockchain. This is an interesting problem because it is a type of feature that we could not implement in a trustless way before.
Which protocols and algorithms should you learn to understand Bitcoin?
Innovations from Bitcoin and Blockchain-related technologies have given birth to a new species of distributed systems. Today, these distributed systems are entirely decentralized.
On the technical side, the field is exploding with innovation. It can be hard to keep track as each week new discussions, algorithms, and projects pop up.
So, as a developer, how do you get started with Blockchain? Where to start to understand these technologies? And which algorithms should you learn to create your own blockchain, or dig into the existing ones?

Where and how application data is stored in Ethereum?
Ethereum is used to build decentralized applications, a.k.a. DAPPs. These applications exist through small programs that live on the Blockchain, called smart contracts.
Before jumping into the platform and writing a smart contract, it’s really important to understand where your application data is stored. Code execution, servers and programming language are rarely critical to the design of an application. But data –its structure and its security– will constrain our design the most.

Beyond the Buzzword: The Problem Blockchain Actually Solves for Developers
Blockchain-related technologies are in full-hype mode these days. The first time I came across the b-word, I had a déjà-vu from the 2010s hype around “NoSQL”. But what is the point of the Blockchain, exactly?
