As the cryptocurrency globe anxiously awaited the years-in-the-building Ethereum merge past 7 days, a group of builders, scientists, and community customers who’ve devoted their lives to the task felt the force mount.
But counting down the blocks as the time passed 2:30 a.m. EST on Sept. 15, the group didn’t waiver in exhilaration. They, alongside the better cryptocurrency local community, had been sending tweets as the approximated timing for the merge acquired nearer and nearer. People collected IRL at the Ethereum Foundation office environment in Berlin—just in time for the notable hackathon EthBerlin, wherever Ethereans satisfy from all above the entire world to rejoice the venture to which they’ve committed their lives—were huddled all around their computer systems on a Zoom call to examine development, share war stories, and, lastly, rejoice.
On the other hand, even with all the aid, doubters remained, some citing how the merge experienced been delayed so many moments in the past, and how an update of this scope, on an energetic network of this measurement, experienced never been carried out.
To their surprise, the Ethereum evidence-of-stake chain commenced to finalize all around 3 a.m. EST, and onlookers witnessed in real time a historic minute in cryptocurrency background. And as it took place, in accurate Etherean fashion, artist Jonathan Mann ongoing his longstanding tradition of singing Ethereum-themed music on neighborhood Zooms—a tailor made he adopted around the study course of numerous pre-merge check phone calls. His most up-to-date tune focused to the merge involved the lyrics: “Carbon footprint is all gone, which is why we’re singin’ the merge song.”
With achievements then confident, the merge was total, and builders and watchers alike cheered.
To outsiders, the spectacle might’ve seemed unwarranted, wondering the merge is just some tedious software upgrade. But for the workforce accountable, it is significantly a lot more than just a technological feat. Apart from becoming a massively essential milestone for Ethereum and the larger cryptocurrency sector, the road main to it was one of 24/7 operate, many checks, workshops, meetups, hackathons, and journey for developers—who turned figureheads inside the crypto neighborhood. Ranging across generations and cultures, the scores of builders and scientists managed to connect and collaborate—week in, 7 days out—to develop Ethereum and get ready for the merge. Here’s how they did it.
‘Big minute for me’
The merge was a long time coming. Considering that Ethereum’s genesis, creator Vitalik Buterin, along with builders and researchers, prepared to shift the network to proof of stake.
Mikhail Kalinin, direct researcher at distinguished Ethereum software enterprise ConsenSys, would shell out 10 several hours for every working day doing the job on it—but it never felt substantially like do the job, he explained to Fortune.
Kalinin, 35, is an Ethereum OG: He began operating on the Ethereum ecosystem in 2015—a month in advance of the Ethereum mainnet, or main general public chain, launched—and finally turned regarded as the “mastermind” driving the merge. In truth, other builders say that without him, the merge wouldn’t have transpired.
In November 2020, Kalinin revealed a proposal for the “Executable Beacon Chain,” and a thirty day period later, the Beacon Chain, Ethereum’s proof-of-stake chain, delivered.
That was a “big minute for me—seeing one thing that I’ve worked incredibly tirelessly on in generation that other people today will be applying,” explained Terence Tsao, the founder of Prysmatic Labs and an Ethereum developer out of San Francisco. Working with the crew since 2018, Tsao, 34, also noticed the enhancement of the merge in its earliest stages—back in advance of it was called the merge, or even Eth2, and was largely referred to as “Shasper,” a mixture of “Casper,” the then-name for Ethereum’s edition of evidence-of-stake, and “sharding,” an Ethereum scaling remedy.
Given that then, builders and researchers have labored on and examined the merge method a lot of times—and these occasions turned most loved recollections to team associates. For one particular, builders and researchers remember the Oct 2021 “Amphora” workshop in Greece.
“It was really fascinating and fascinating to see individuals that you have interacted with on the net initial for so extensive in man or woman,” explained Ethereum Foundation computer software developer Marius van der Wijden, who’s primarily based in Germany and has led function on the common Go Ethereum (Geth) shopper since 2020.
That vacation was quite on-manufacturer for the lighthearted Ethereum neighborhood. For case in point, dapplion, a pseudonymous Ethereum main developer at Lodestar, wore a Lion costume for most of the trip. “I was carrying that fit on distinctive times,” explained dapplion, 29, laughing.

But to van der Wijden, 26, the “funniest thing” was not the lion costume. As an alternative, it was witnessing about 40 builders and scientists continue to be in a 5-star resort in Greece—and under no circumstances leave the basement. “We sat there in this relatively little area, coding, all hunched above pcs, from morning to night,” mentioned van der Wijden.
Their goal was to make development and “iron out” some troubles about the merge transition—and they did just that. They did not know it at the time, but it would go down as a significant “milestone” on Ethereum’s highway to evidence of stake.

“We managed to demonstrate that the in general idea or architecture that we were making use of labored, and I consider that was, with regards to the merge, the most energizing moment,” explained Tim Beiko, the protocol support guide at the Ethereum Foundation who helped manage the journey.
On the past day of the function, “we wanted to try to make the merge in fact occur on a testnet [or Ethereum test network]. We managed to make this check work five minutes just before we all had to leave,” said Ethereum Foundation devops engineer Parithosh Jayanthi, who joined the workforce in 2020 and led most of the pre-merge screening. Eventually, completing it was “an remarkable emotion,” Jayanthi, 28, explained. “I absolutely will not neglect that one particular.”

‘Meetings just after 10 p.m.’
Long operate days—and nights—isn’t uncommon for this bunch. Their dedication to the merge, and passion for Ethereum, usually outweighed their want for breaks or sleep. Additionally, with developers and researchers throughout the entire world in various time zones—Australia, Germany, India, Poland, Switzerland, the U.K., and the U.S. among the them—working odd hrs grew to become regime.
Ethereum Foundation researcher Hsiao-Wei Wang is aware of this effectively. She’s labored on the Ethereum ecosystem with the team because 2017, contributing to the merge in a lot of ways—including her generation of the viral panda merge meme. Based mostly in Taiwan, she normally functions late at evening in get to link with her colleagues. “I am employed to owning conferences right after 10 p.m.,” she explained to Fortune.
But this “enormously collaborative” exertion is “critical” to the achievement of Ethereum, mentioned Ben Edgington, item proprietor of popular Ethereum client Teku at ConsenSys, wherever he started functioning in 2017. “That’s the form of community we want to build—the community wherever no person owns it, and exactly where it allows a substantial range of builders.”
The Ethereum community—much like other cryptocurrency-connected communities—is on the net 24/7. “We are inclined to dwell where by we operate, so it is quite challenging to shut the door and say, ‘OK, my day is in excess of,” additional Edgington. “Also, every little thing we do is interesting. There just aren’t enough hrs in the working day. There’s this drive to consume it.”

However specific motivations in bringing the merge to lifestyle may possibly fluctuate, most developers and researchers explained lessening Ethereum’s environmental impact was among the the most essential. With a track record in local weather dynamics, the shift was in particular critical in the eyes of Edgington—and his 18-calendar year-old daughter.
“I was conversing to her about NFTs, and she went crazy. Like, ‘How can you do this? You’re boiling the ocean. This is my potential.’ And I was extremely pleased to be equipped to say, ‘Actually, my life’s operate now is to fix that. This is what I’m in fact performing,’” he mentioned. “This move to proof of stake is an necessary move.”
Several doing the job on the merge observed their attempts as making “the most impression any of us separately could have” in protecting against local weather improve, reported Jayanthi, incorporating that he viewed it as a way to counteract “probably the carbon price range of my total life…which is crazy to imagine about.”
“In 50, 100 years down the line, people will look at the merge like, ‘Oh, wow, the merge truly improved history,’” Tsao claimed. “It’s genuinely huge, but I truly feel like folks haven’t understood that. We are in such early times.”
