Milestone designating a steep ∠9% section of the bike route to Mont Ventoux in France.

Tezos is an on-chain governance blockchain protocol built on liquid proof-of-stake (LPoS) algorithm for consensus. Being PoS protocol, it relies on validators (aka “bakers” in Tezos lingo) to ensure network security. You can find detailed description of proof-of-stake consensus here. What differentiates Tezos from the other PoS protocols is its on-chain governance. Specifically, the blockchain was designed as a self-amending blockchain network and allows activating new protocol versions without a need for a hard fork through on-chain voting process. The latest such upgrade took place on November 12th, 2020, when Tezos blockchain self-upgraded to Delphi protocol.

In this article, we will discuss the analysis of the impact the Delphi upgrade had on Tezos network performance and Tezos validators community. …

When operating a Polkadot validator, it is critical to maximize your uptime in order to avoid being penalized.

Good practices of a node operator incude disaster recovery: the ability to quickly repair your operations in case of failures. For example, if your hard drive dies, you need to recreate your node from scratch. As time passes and the number of historical blocks grow, it can take a prohibitive amount of time to synchronize your node to the head of the chain. During this time, you may be marked offline and lose your rights as a validator.

We are proud to introduce Polkashots.io, a website where you can download recent snapshots of the Polkadot chain, regularly updated and fast to download. This website was developed thanks to a Web3 Foundation grant. …

The clock is ticking before the Tezos blockchain upgrades itself to the next protocol Delphi. Mark the date: Nov 12th, 2020 12:28 pm UTC. The details on the proposal can be found here.

As part of our preparedness for the upgrade we took a comprehensive look at the impact of the previous upgrade to Carthage had on Tezos network performance and Tezos baking community. Carthage upgrade was executed on Mar 5th, 2020 04:38 am UTC before cycle 208.

We aimed to answer the following questions:

  1. Were bakers ready for the upgrade?
  2. What was the impact of the failures to upgrade on-time on the network? …


Introducing polkadot-k8s

We are introducing polkadot-k8s, an open-source project designed to spin up a secure Polkadot or Kusama validator setup in one shot. Polkadot is a sharded proof-of-stake blockchain, and Kusama is Polkadot’s canary network.

We have been successfully operating a Kusama validator, Hodl.farm, for two months using this model. We also operate a Tezos bakery on Kubernetes.

In this tutorial, we will show how to deploy a validator on Google Kubernetes Engine with just a few utilities on your laptop. Everything is automated and specified in code. There’s no need to compile any Rust code or install any startup script.

This is not a magic bullet! Being a validator requires care and constant attention, but you may find it a good starting point as you set up your own operations. …

The emergence of proof-of-stake networks

Today’s established blockchains establish consensus by wasting energy and resources, and they suffer from heavy centralization. Proof-of-stake opens a greener and safer chapter in cryptocurrency evolution. Tezos, Polkadot, and Ethereum 2.0 are, in our opinion, the most promising networks.

Proof-of-stake cryptocurrencies have inflation. Token holders must take action for their assets to grow: they must put them at stake on the network.

Unlike proof-of-work blockchains, the computing resources required to operate full nodes are small. But the intricate incentive systems in place to protect the network put your funds at risk of “slashing” if your node misbehaves or becomes offline. …


With the Tezos-on-GKE project, you can deploy a complete baking infrastructure faster than ever before.

Update: we have now launched our staking-as-a-service company, MIDL.dev. We can help you deploy and manage the infrastructure described in this article. Contact us to become a baker !

There are many tools and instructions out here to bake Tezos. We want to take it a step further. In this article, we present a simple way to spin up baking infrastructure in the cloud.

The Tezos network thrives when there are many baker nodes in the network. Babylon, the most consequential on-chain amendment to the Tezos protocol, went through a few hurdles when it went live a few days ago. If more people had joined Babylonnet (the testnet for the upgrade) more bugs would have been caught prior to launch. …
