Yesterday, Regen Network launched its final testnet, Aplikigo, which will be running until March 8th 2021. The testnet saw such a huge rush of applications that the validator set had to be increased from 100 to 125 validators and the application period had to be cut short. The enthusiasm and anticipation in the community are palpable and we at blockscape certainly share the excitement with all the other participants of having the opportunity to be a part of Aplikigo.

Our journey with Regen started all the way back in the Algradigon testnet, and we’ve been actively following the network’s development…


From October 16th till October 31st, Tendermint hosted their fifth Hackatom which we took as a great opportunity to flex our creative muscles and learn something in the process. Our team has been working very hard (and also very late) on stitching our project together and we’re very proud of what we achieved. With that being said, we’d like to share our Hackatom V experience with you in this article, what we’ve accomplished, hurdles we had to overcome and what we’ve learned at the end of the day.

Of course, this whole endeavor would not have been possible without the…

Where We Left Off

In our last article, we introduced Raftify, our second iteration of a high availability solution for Cosmos validators. For those out of the loop, here’s a brief introduction:

In a nutshell, Raftify implements the Raft leader election algorithm in order for validator clusters to manage themselves by assigning signing responsibility to the leader node. …


Hello cosmos community, in this article I will summarize what we have achieved in the Game of Zones game and what insights we could gather.

Phase 1

As already known, the first phase was divided into two sub-phases Phase 1A and Phase 1B.

For the first phase we have extended the relayer with a keepalive command.

https://github.com/BlockscapeLab/relayer/blob/keepalive/cmd/keepalive.go

This command allowed us to automatically update the client for the connection. In addition, we implemented a monitoring function that delivers the current status to a Prometheus backend.

The Grafana user interface, which is connected to Prometheus, prepares the data and displays it in a…

As you may already know, on March 20th, an unfortunate misconfiguration of our active/active validator caused a double-signing incident which lead to our validator being slashed and tombstoned as a consequence. In this article, we’d like to go into a bit more detail as to what exactly we did to resolve this issue and how we move forward.

What Happened?

Today, on May 20th, our Cosmos Hub 3 validator had a double-signing incident at block height 1,955,889. As a result, all of our delegators’ stakes have been partially slashed in the process. …

Where We Left Off

In our last article, we’ve established the theoretic foundation for a highly available validator in an active/active setup with a Raft consensus middleware layer. This approach provides a couple of key advantages that make it a reasonably good fit for use in production.

  1. Running multiple validators in parallel, backing each other up in failure scenarios, means there is no…

Having a diverse selection of peers amongst your validator nodes is extremely important in a blockchain network. It is precisely this diversity that fosters decentralization and combats censorship. …

Guide Assumptions

This guide is designed for validator operators who want to make their own validator highly available. It assumes you have a basic understanding of Tendermint and general Proof of Stake related terminology.

By following along with this guide, you’ll get a good understanding of why high availability is necessary to operate a validator responsibly and how it can be…
