Hebdo Crypto #203 – Bitcoin and cryptocurrency news of the week



The week of 08/08 in brief – The news about Bitcoin and cryptocurrencies is constantly boiling. It can happen that crucial information gets lost in the daily information flow and that you miss important points. This format is there to remedy that. We return to thenews from the past weekCrypto Weekly to keep you informed about the current situation of cryptocurrencies.

The unmissable corner

For the return of the Unmissable du Coin, what could be better than a tutorial from our dear editorial director Gregory ? This week, he put on his best HackerMan costume to offer you a tutorial on how to deploy a celestia validator node.

Celestia modular blockchain


Celestia has a very specific architecture. Traditionally, the blockchain design model couples consensus mechanism and transaction execution. One of the approaches aimed at improving the scalability of the latter is based on sharding, that is to say the fragmentation of the data composing the main chain.

With Celestia, the two layers – consensus and execution – are separated. The role of the consensus mechanism is only to ensure that the block data is available. To do this, it uses data availability proofs. The transactions are then executed off-chain: the nodes no longer need to process them to ensure the validity of the blocks.

The nodes randomly sample small portions of the blocks in the chain. It’s quite similar to peer-to-peer file sharing (BitTorrent) where files are split between network nodes.

Once the blockchain is fully sampled, we obtain the famous proofs of availability of said data.

Unlike “traditional” blockchains, Celestia is designed to provide evidence of data availability and consensus, not transaction execution. Celestia therefore relies on a network of light nodes (allowing anyone to deploy a client in minutes) and full archiving and validating nodes (the type of node we will learn to deploy in this article).
