In this blockchain development course, you will learn how to query on the blockchain and build open APIs. This course will teach you how to build your own distributed applications using The Graph. It's like Lego blocks for composing your own protocols. You'll learn how to build your own APIs that query Ethereum, IPFS, and other data sources.
This course is all about querying data on Web3 decentralized applications. You will get an introduction to indexing and querying data on the Ethereum blockchain. Querying data on decentralized networks is very different than what you may be used to on the traditional web.
By the end of this course you will have the knowledge to query data from the Ethereum mainnet as well as a variety of other chains in order to build you own decentralized apps.
You will learn how to use The Graph. It is an indexing protocol for querying networks like Ethereum and IPFS. Anyone can build and publish open APIs, called subgraphs, making data more easily accessible.

In graph theory, a bridge, isthmus, cut-edge, or cut arc is an edge of a graph whose deletion increases its number of connected components. Equivalently, an edge is a bridge if and only if it is not contained in any cycle. A graph is said to be bridgeless or isthmus-free if it contains no bridges.
A graph with 16 vertices and 6 bridges (highlighted in red)

In computer science, a graph is an abstract data type that is meant to implement the undirected graph and directed graph concepts from mathematics, specifically the field of graph theory
A graph data structure consists of a finite (and possibly mutable) set of vertices or nodes or points, together with a set of unordered pairs of these vertices for an undirected graph or a set of ordered pairs for a directed graph. These pairs are known as edges, arcs, or lines for an undirected graph and as arrows, directed edges, directed arcs, or directed lines for a directed graph. The vertices may be part of the graph structure, or may be external entities represented by integer indices or references.

this tutorial gets you started with neo4j from installation to building your own graph databases. this starts from installing neo4j with docker (even on an apple silicon m1) and then building a graph database in neo4j using CYPHER to create nodes, relationships, labels and properties. finally i bring it altogether with a software supply chain example in graph in neo4j.
this tutorial is suitable for beginners who want to create their own graph db in neo4j from scratch

What is the session about?
The Microsoft Graph Toolkit is a group of reusable, framework-agnostic components and authentication providers for working with Microsoft Graph. You can add components to existing applications, and work in any modern browser. Join us as we chat with Beth Pan about the toolkit. In the previous session we chatted on how you can incorporate otherwise complex functionality, including authentication, with just a few lines of code. This time, we will talk about advanced technics, tips, and tricks in customizing and configuring Microsoft Graph Toolkit components.
Who is it aimed at?
This is for anyone who is a novice with the Microsoft Graph Toolkit and wants to learn more advanced uses.
Why should you attend?
This is a great opportunity to learn more about Microsoft’s Graph Toolkit!
Presenter Info: Beth Pan is a software engineer with Microsoft. She works with 1st and 3rd party developer ecosystems and help them unblock in order to build on top of Microsoft technologies and platforms. Currently she’s working on the Microsoft Graph Toolkit team to make it easier for developers to integrate their apps with Microsoft Graph.

How to find the best rooms with the most gold to get better equipment, more powerful monsters and more XP? Well … the answer is GraphQL. Being a developer himself, Guy Royse thought this problem was best solved using a database to figure out the best way to pass the dungeon & maximise gold / minimise danger.
