This coming Friday I will be taking a work break for 6 months. It’s been a long time without any real pause working in the exciting and fast-paced crypto industry since 2016, and my partner and I had planned this before Corona hit and are now going ahead with it to rest, relax and rejuvenate our energy before the next step in life.

It’s been so exciting to work with so many of you in the EOSIO, Ethereum, blockchain, self-sovereign identity, cryptography, and information industry. I’ve really enjoyed the experiences I’ve had and contributions I’ve made in so many blockchain…

Gimly has built a full draft of the EOSIO Decentralised Identifier (DID) method specification. This specification guides the implementation of DIDs on EOSIO powered blockchains.

Find the full announcement here with the EOSIO DID Specification and signup for the EOSIO Identity Working Group.

Excerpt from the EOSIO DID

Gimly is excited to announce the EOSIO identity working group (Twitter #eosio_id)! This open working group (WG) will create and foster identity solutions using EOSIO technology, by creating open W3C compliant self-sovereign identity (SSI) standards, interoperability, and ecosystem development for eosio based identities.

We bring our strong experience in self-sovereign identity and EOSIO to the WG.

Please join us for the kickoff event Monday 12th April 3pm GMT / 11am EST open for all interested in identity on EOSIO!

PS. We have the EOSIO DID method spec written and will release it next week as part of the first work item of the group.

As the last act of our company, we have decided to open-source our production-grade recruitment application software with an open license that we used to run! This MEAN stack application runs a candidate-based recruitment platform. Companies apply to candidates based on their profiles (same model as We hope that this can be put to good use by developers and/or business owners!

This article will explain the advantages of our upgrade to the existing Openstad participation tool currently in use throughout the Netherlands, currently called the Civic Participation Tool. Please see the previous article for an introduction, demo, and source code.

Openstad is a tool that is run by several neighborhoods in Amsterdam, The Hague, and other cities in the Netherlands. It allows citizens to propose changes to the infrastructure (e.g. “Create a new flower bed next to the boulevard”), and for those proposals to be voted on by the citizens. The proposals with the highest votes are then executed by the…

During the Odyssey Momentum event over the weekend our team, The New Fork Partners!, built a democratic voting tool to allow citizens to participate in building their neighbourhood. This was to address the challenge given by the city of The Hague, the political capital of the Netherlands.

OpenStad is an existing democratic participation tool already in use throughout several cities in the Netherlands. What we built exhibits a significant upgrade to the security, scalability, trust and inclusiveness which OpenStad provides.

This was done by replacing the proposal and voting data and logic server/database architecture with a customized eosio blockchain, using…

I am writing this article because there seems to be a lot of confusion about the difference between EOSIO and EOS. Unfortunately, there are problems with EOS and the biggest problem is that people associate this with EOSIO which is not the root of the problem.

EOSIO software

A free, open-source software that can deploy highly customizable blockchains on which developers and entrepreneurs can run high-performing blockchain applications.

The software is created and maintained by Block One (B1).

EOS blockchain

A deployed blockchain powered by the EOSIO software.

The blockchain was deployed and is managed by the EOS blockchain community.

This article is a summary of the new research and development since 2018 in the area of upgradeable Ethereum smart contracts. It presents the new works and standards that extend Summary of Ethereum Upgradeable Smart Contract R&D — Part 1–2018. Please read it to become familiar with the background leading up to this article.

This article intends to be a convenient and centralized place to understand upgradeable smart contract strategies. If you are watching or involved in this area of R&D, please comment on this article with any insights, feedback or comments that may be useful for others.

Thank you…

Bitcoin is the oldest and currently highest valued cryptocurrency. However, Bitcoin and many cryptocurrencies have several major issues that this article will discuss. Some issues are well known and spoken of, however I want to add some more focus on the ethical, social and political impact that these systems have, the ones that are not being discussed enough.

These problems apply to most of the public, permissionless, psuedo-anonymous cryptocurrencies including Bitcoin forks, Ethereum, a lot of Ethereum defi products, Monero, Zcash, EOS and many more.

I hope this article can make people think a bit deeper about what is being…

This workshop is for software developers interested in building blockchain applications using the EOSIO blockchain software framework. To complete the tutorials and to follow most of the content you will need to have some experience in software development/coding. This knowledge can be used to build applications on public or private blockchains powered by EOSIO (such as EOS or Telos) or deploy your own highly customizable public or enterprise blockchain.

If you are not confident with C++ then I highly suggest you download the first chapter of the Learn EOS book by Christoph Michel. You can get it for free here
