This is the fourth episode in our series covering the basics of HOPR. Links to previous episodes can be found at the end of the article. Last time we took a first look at the problem of sending data privately online without anyone being able to track it or work…

This is the third episode in our series covering the basics of HOPR. Previous episodes can be found here (Episode 1 — What is HOPR?) and here (Episode 2 — What is Metadata?). Last time we learned about the huge amount of connection metadata created every time we do anything…

Things have been a little quiet on the tech front, but not because we haven’t been busy — quite the opposite, in fact! Since the HOPR token launched in February, we’ve been all hands on deck working towards our upcoming Eiger release. We know you’ve all been waiting patiently —…

Ocean Protocol is introducing Ocean Market, a platform for buying and selling access to data. Building the amazon.com of data means keeping mainstream users in mind, which is why the Ocean team decided to build with Portis. In this article, Manan Patel, Growth Accelerator for Ocean, shares their vision with us. — Jose Aguinaga is a Developer Evangelist representing Portis. Portis is a self-custodial, embedded blockchain wallet. Portis delivers top developer experience to DApp developers, giving their users a friendly onboarding experience.

The Portis whitepaper showcases how user accounts are generated, encrypted, and safely stored. Using key derivation and end-to-end encryption, your crypto wallet is always under your control, and the keys are only known to you and no one else. But the whitepaper is technical and complicated, so let’s simplify things the best way possible — with alcohol! — The motto “not your keys, not your crypto” is one of the greatest maxims in the blockchain ecosystem. The challenge lies in the fact that by knowing the keys behind your crypto account, anyone can have access to your assets, and thus, your keys must be only known to you…

Transactions must be signed by a private key in order to hold any value. Since all digital assets are created from transactions, signatures play a critical role in any blockchain. In this article, we’ll learn how Ethereum transactions are signed. — In our previous articles, we went through the process of creating a private key and learned what can be done with it. Specifically, in part one, we learned that keys are nothing more than random numbers of astronomical proportions, whereas in part two we looked at how these numbers can…

One of the things HOPR became best known for in 2020 was our incentivized and gamified testnets (RIP Coverbot, we’re not that sad you’re dead!) …

After almost a year of hard development work and testing, we’re very excited to announce the first public release of the HOPR protocol: HOPR Jungfrau. We need to begin this post with a few warnings, disclaimers and caveats. …

All crypto addresses come from somewhere. In this second installment in our mini-series, we’ll build on our newfound knowledge of private keys and see how your browser transforms a randomly generated sequence of ones and zeros into a unique wallet address owned by you and you alone. — Disclaimer: Please bear in mind that all the private keys generated and used in this article are only for educational purposes.
