Crypto Weekly #133 – This week’s Crypto News

The week of 08/02 at a glance – News about Bitcoin and crypto-currencies is in constant turmoil. It can happen that crucial information gets lost in the daily news flow and you miss the important points.

This format is here to help. We look back on last week’s news in Crypto Weekly to keep you informed about the current state of cryptomoney.

The unmistakable of the corner

For this week’s must-read, we’re going to look at an article I had the pleasure of writing. As Ethereum struggles with ever-increasing transaction costs, second layer solutions such as Optimism are looking to solve scalability problems. Let’s see what Optimism is all about.

Ethereum’s problems

As it stands, the Ethereum network has a processing capacity of about 30 transactions per second. Although its characteristics have allowed it to evolve so far, the limits of the network have been constantly reached since the beginning of 2020.

In practice, the network has consistently exceeded 90% utilisation since April 2020. At the time of writing, this level has steadily increased to 97.8%. As a reminder, network usage is calculated on the basis of the average gas consumed, compared to the maximum gas limit set by the protocol.

As a result of this high usage, network transaction costs exploded, eventually reaching a record average of $17.5. Worse still, some interactions with decentralized applications can cost tens of dollars.

The second layer to the rescue

As it stands, the majority of the traffic recorded by Ethereum, as well as a large part of its decentralised applications, takes place on layer 1, i.e. the Ethereum blockchain.

Consequently, the vast majority of the actions carried out on Ethereum draw on the limited capacity of the network.

As for the second layer solutions, they aim at shifting part of the activity out of the main chain. Nevertheless, these solutions rely on the main chain to ensure better security.


Optimism is a project initiated in June 2019, which takes advantage of Rollups to offer a second layer solution to the Ethereum network. In theory, this solution would be able to process more than 20,000 transactions per second.

It therefore provides near-instantaneous transactions, smart contracts and, all this without the need for gas.

The project is led by the Optimism Public Benefit Corporation, founded by Jinglan Wang.

The protocol made headlines in September 2020 with the launch of a testnet on Ethereum. Based on this success, the protocol was finally deployed on the mainnet on January 15, 2021.
