Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

HOPR net

HOPR is a privacy-preserving messaging protocol that incentivizes users to participate in the network. It provides privacy by relaying messages via several relay nodes to the recipient. Relay nodes are getting paid via payment channels for their services.

hopr-core-connector-interface

This repo defines the interface between hopr-core and blockchains that are able to process HOPR incentives. The details of the on-chain logic are left to the implementor and must follow the whitepaper, examples are hopr-polkadot and hopr-ethereum.

Chain requirements

The HOPR protocol comes with some requirements that must be met by chains that process its incentives. As HOPR is meant to be open and inclusive, the requirements for on-chain operations are intentionally kept very basic in order to not exclude any specific chain. Nevertheless, the following requirements are mandatory:

  • On-chain hash verification of custom bitstrings
  • On-chain signature verification of custom bitstrings
  • On-chain binary operations on custom bitstrings
  • A reasonable instruction limit to support small programs
  • A general-purpose programming language to define the on-chain logic

Probably unsupported chains (in alphabetical order):

  • Bitcoin
  • Bitcoin Cash (and derivates)

This holds also for all other blockchain that rely on Bitcoin Script and / or come with a very restrictive instruction limit.

Implementors (in alphabetical order):
