Walking through an ERC20 Contract #erc20contractbreakdown

You may have purchased tokens from an exchange but what does that mean? What happens when you transfer coins from an exchange to your wallet? We’ll walk through the code behind ERC20 tokens. This is a technical session, but will certainly help anyone take the abstraction out of crypto.

Simplify Bitcoin Development #bitcoindev

Satoshi Nakamoto once proclaimed that an alternative implementation of a blockchain codebase would be “a menace to the network”. Bcoin is an enterprise-level implementation of the Bitcoin protocol, written from the ground up entirely in JavaScript,to be secure, scalable, and maintainable. Today it is used in production at companies and projects across the industry, including at Purse.io, Edge Wallet, BitPay, and Chronobank.

Buck Perley, Engineering Lead Purse.io Buck works full-time on bcoin and derivative projects. He will be joining to talk about how bcoin can help you develop better, more secure cryptocurrency applications, how an alternative implementation can make the ecosystem and network stronger, and some of the exciting projects their team is working on including bPanel, the world’s first Blockchain Management System (BMS).

Buck gives a live demo for how to build something on bPanel and a live demo for working directly with the bcoin backend
