Hebdo Crypto #203 – Bitcoin and Cryptocurrency News of the Week

Briefly about the week of 08/08 – News about Bitcoin and cryptocurrencies is constantly boiling. It can happen that crucial information gets lost in the daily flow of information and you miss important points. This format is here to fix that. We come back tonews from the past weekCrypto Weekly to inform you about the current situation with cryptocurrencies.

An unmissable angle

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


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

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

Nodes randomly sample small portions of blocks in the chain. It is quite similar to peer-to-peer file sharing (BitTorrent) where files are shared between network nodes.

Once the blockchain is fully sampled, we get known evidence of the 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 lightweight nodes (allowing anyone to deploy a client in minutes) and full nodes for archiving and validation (the type of node we’ll learn to implement in this article).
