Ethereum: the Sepolia testnet is preparing for The Merge

The Merge in the making – The network Ethereum is a few months away from an unprecedented development. Indeed, this one will change mode of consensus, moving from proof of work to proof of stake. So this transition will be done through a process called ” The Merge “. While waiting for its release on the mainnet, the developers are testing the update on the testnets, sepolia being next on the list.

The Merge: Nothing should be left to chance

For several months, the developers of the Ethereum network have been multiplying initiatives to test long and wide the deployment from “The Merge”. Indeed, the maneuver is not trivial. Nothing should be left to chance for what may be likened to open-heart surgery.

After testing the transition on several shadow forksthe developers have moved up a gear by tackling the testnets. Thus, on June 8, the developers successfully deployed The Merge on the Ropsten testnet. A first conclusive step, allowing the oldest Ethereum testnet to move to proof of stake.

However, all is not won. This transition was not made without some bugs, failures and desynchronizations. Nothing more normal, for a blockchain which communicates a dozen different customers.

Therefore, new testing scale must take place, before a deployment final from The Merge on the mainnet of Ethereum.

Sepolia prepares for The Merge

sepolia is a testnet of the Ethereum network, launched in October 2021. Eventually, it will replace the historical testnet Ropsten.

As part of “The Merge”, Sepolia will be the second testnet experiment with the transition to proof of stake. To do this, however, it must have its own ” beacon chain “.

As a reminder, the beacon chain represents the layer of consensus in proof of stake of Ethereum. The Merge update aims to link this beacon chain to the layer application of Ethereum, spawning one and the same chain in the end.

So, on June 20, Ethereum developers announced the deployment of a beacon chain specific to the Sepolia testnet. Its deployment marks the beginning of a series of actions that will ultimately lead to the publication from The Merge on an additional testnet.

Nethermind indicates the deployment of a beacon chain specific to Sepolia.

No date has not yet been announced for the Implementation of transition. By way of comparison, the time between the deployment of the beacon chain and that of The Merge on Ropsten was about twenty days. Therefore, it is likely that The Merge is deployed on Sepolia during the second week of July.

Note, however, that the launch will depend on the potential evolution of customer specifications by then. Fixing any detected bugs could also delay the rollout.

The mainnet on the alert while waiting for The Merge

In parallel, the preparations continue on the Ethereum mainnet. So the developers decided to fend off the difficulty bomb a hundred days. In practice, this allows them to grant themselves an additional reprieve so as not to have to rush the deployment of The Merge.

Without going into details, the difficulty bomb aims to gradually increase the difficulty mining on Ethereum, to ensure that the minors will abandon the chain in proof of work, once the transition to proof of stake finalized.

However, this leads to a increase from the time of blocks (time block). Therefore, its postponement avoids a slowdown in Ethereum pending the deployment of The Merge.

Note all the same that the postponement of the difficulty bomb does not necessarily imply report of Tea merge. As Ben Edgington pointed out on Twitter :

They say it won’t delay the merger. I sincerely hope not. Each additional week on the PoW generates almost a million tons of CO2 emissions. »

For its part, Ether suffered like the rest of the market from significantdrops. Thus, it has fallen back below the $1,000 mark in recent days.
