Sepolia Testnet Runs Through The Merge Successfully: Details

Ethereum developers have completed the Merge on the Sepolia public testnet. With the last testnet deployment inbound, Ethereum is set to transition into a proof-of-stake (PoS) blockchain.

Sepolia Testnet Activates The Merge

After years of work to bring proof-of-stake to Ethereum, the team is gradually getting closer to making the shift happen, as testnets deployments are being wrapped up successfully.

The purpose of running the Merge on public testnets is to final test and/or trial run the complex upgrade before it is activated on the mainnet.

In other words, the goal is to check if the validator nodes from both the execution layer (PoW) and Beacon chains (PoS) of these testnets can work together. Their successful implementation implies that mainnet activation will be a success too.

As earlier announced, Sepolia is now the second of the three public testnets to run through the Merge after the Bellatrix upgrade had previously been implemented on the testnet’s Beacon Chain.

In the Merge event, Sepolia’s execution layer, operating as proof-of-work, “merged” with its beacon chain consensus layer which runs as proof-of-stake. In achieving this, node operators on Sepolia’s consensus and execution layers updated their client software accordingly.

The summary of the event was then published by a lead Ethereum developer. Terence.eth noted that the Merge transition itself on Sepolia testnet was a success. Afterward, 25-30% of the validators went offline shortly after the merge, citing that the offline validators were due to wrong configurations. However, he noted that the offline parties have updated their configurations, and validators are up.

There’s no client bug and these hiccups will not delay the Merge. Finally, this is what testnets are; to enable interested parties to test their setups and configs. Better now than the mainnet, he added.

Sepolia summary:
– Merge transition itself was a success
– 25-30% of the validators went offline shortly after the merge
– The offline validators were due to wrong configs
– Since then, the offline parties have updated their configs, and validators are up

Georli/Prater Testnet and Mainnet Merge Next Up

With the Ropsten and Sepolia testnets now merged, Georli/Prater will be the last testnet to trial run the Merge before the actual mainnet Merge event comes up. Notably, Goerli is an execution layer testnet while Prater is a consensus layer testnet.

According to the team, the exact date for the Merge is yet to be determined. However, after the Georli testnet upgrade, the expected date for the much-awaited Merge will be disclosed.

Sepolia Testnet Merge Up Next; Ethereum Blockchain Proof-of-Stake (PoS) Transition Nears

Sepolia, an Ethereum public testnet, which has already run through the Bellatrix upgrade on the Beacon Chain, is now ready to run through the Merge in the next few days.

Sepolia Testnet Merge: Details

It is no longer news that the Ethereum network is gearing towards a transition from its current Proof-of-Work (PoW) consensus algorithm to Proof-of-Stake (PoS). Ethereum intends to achieve this through the implementation of the Merge upgrade on its Mainnet.

Although the date for this epic upgrade is yet to be determined, the Ethereum mainnet Merge is around the corner considering that the team is currently final testing the Merge on public testnets.

With the execution of the Merge on the Ropsten Testnet, Sepolia will be the second of three public testnets to run through the Merge. While the Goerli/Prater testnet will be the last to test run the Merge before the upgrade heads to the mainnet.

Notably, Sepolia went through the Bellatrix upgrade in June 2022, at epoch 100. With the successful Bellatrix upgrade, the Sepolia Beacon Chain was prepared for the Merge. Also, the Bellatrix upgrade caused Sepolia’s Terminal Total Difficulty (TTD) value to be changed from the initial high value of 100,000,000,000,000,000,000,000.

This implies that the Sepolia testnet network will migrate to proof-of-stake (PoS) at an undisclosed date when the Terminal Total Difficulty (TTD) on the proof-of-work (PoW) chain exceeds 17,000,000,000,000,000.

In addition, Sepolia Merge will be a two-step process. According to the team, the process will begin with a network upgrade on the consensus layer at a certain epoch height.

Sequel to this, Sepolia’s execution layer (also known as Paris) will kickstart the transition from proof-of-work (PoW) to proof-of-stake (PoS) when the chosen TTD is reached or exceeded.

To complete the process, a Beacon Chain validator has to solely produce a succeeding block after the Sepolia’s execution layer has exceeded the chosen Terminal Total Difficulty.

“Assuming normal network conditions, this should happen 2 epochs or approximately 13 minutes after the first post-TTD block is hit.”

Sepolia’s testnet Merge is said to be achieved once the Beacon Chain creates this block.

Post-merge, only the Sepolia, and Georli testnets will remain very valuable. Others will be deprecated. Similarly, Sepolia will operate entirely under proof-of-stake after the Merge. Therefore, mining will no longer be possible on the network. The same will be the case on the Ethereum blockchain when the mainnet Merge goes live.

Ethereum Mainnet Merge

While many are awaiting this huge upgrade on the Ethereum mainnet to happen, no date has been announced yet. To estimate the exact date for the actual Merge, the final testing will be done on Goerli/Prater public testnet. Goerli is an execution layer testnet while Prater is a consensus layer testnet.

Furthermore, all three testnets deployments must be confirmed successful and stabilized to execute the mainnet Merge. Once confirmed to be stable, it is said that an epoch will be chosen for the Bellatrix upgrade on the mainnet Beacon Chain.

Also, a difficulty value will be set for the mainnet transition. Lastly, releases that will enable the Merge on the mainnet will then be issued by clients. It is at this point that the team will disclose the date for the consensus algorithm transitioning.
