At Fb, Sam Blackshear created Transfer, a programming language tailor-made particularly for blockchain purposes, however Diem, the cryptocurrency powered by Transfer, by no means launched.
When lawmakers in the USA quashed Fb’s cryptocurrency ambitions, Blackshear and others searched for brand spanking new purposes for the language they created. It didn’t take lengthy to seek out them. Right now, a number of profitable blockchains use Transfer, together with Aptos, Sei and Sui, the latter of which Blackshear continues to work on as chief know-how officer of Mysten Labs.
Cointelegraph spoke with Blackshear to find why the top of Diem was only the start for Transfer and why it’s a more sensible choice for constructing blockchains than Solidity, Rust or different preexisting languages:
“The 2 high-level factors are that Transfer is safer and extra productive,” Blackshear informed Cointelegraph. “I’ll contact on the security level first. In my earlier life, earlier than becoming a member of Libra and creating Transfer, I labored in static program evaluation and program verification, the place I spent all day bugs that actual programmers wrote and attempting to determine ‘What led them to introduce this? Did the language get of their approach? Is it simply essentially exhausting?’ All of those types of issues.”
“I did that very same research on Solidity. To provide one concrete instance, a distinguished bug on the time was the EthereumDAO hack. This was an enormous occasion that led to some huge cash being misplaced and brought about Ethereum to fork. Once we regarded on the essence of the DAO [decentralized autonomous organization] hack, the basis trigger was the reentrancy difficulty… so with Transfer, one of many issues we did is we mentioned we’re not going to have reentrancy.”
On the productiveness aspect, Blackshear explains, “We have now this object-based abstraction that simply makes it very, very direct to translate your ideas into code.”
The tip of the start
In 2018, Mark Zuckerberg’s Fb assembled a crew of consultants in cryptography, programming and distributed programs. Their mission? To construct a brand new global-scale, blockchain-powered funds community from the bottom up.
It was a monumental endeavor of unimaginable ambition, however the venture, initially named Libra earlier than rebranding as Diem, by no means noticed the sunshine of day. A cryptocurrency developed by Fb had one deadly inescapable flaw: it was a cryptocurrency developed by Fb.
It’s a problem of which the social media big appeared greater than conscious. From the outset, Fb tried to unfold duty for the venture as broadly as potential, bringing a number of companions alongside for the journey, together with PayPal, Uber, Vodafone, Spotify, Visa and Mastercard.
However irrespective of what number of associates Fb assembled, Diem struggled to seek out approval amongst regulators and the general public alike.
As Blackshear says, “In summer season 2021, there was a selected level the place there have been a variety of these false begins, instances the place it regarded like we had been going to launch. After which there was one explicit factor that occurred throughout that summer season that simply made it very clear — that is by no means going to occur.”

In the summertime of 2021, the USA Federal Reserve normal counsel Mark Van Der Weide informed Fb it was uncomfortable greenlighting any stablecoin venture till it had a “complete regulatory framework” in place.
Fb requested conferences with U.S. Secretary of the Treasury Janet Yellen and Federal Reserve Chair Jerome Powell, however their pleas fell on deaf ears. No conferences ever occurred.
Diem was lifeless, however Blackshear and his colleagues had been seeking to the long run.
“We reached a degree the place we hit the necessities for launching Diem from a tech perspective, and we had been in a holding sample when it comes to partnerships and regulatory stuff,” mentioned Blackshear.
When the axe lastly fell, it was virtually an act of liberation. “At that time, we had performed all this analysis to determine, ‘How will we construct the higher model?’ That’s once we determined, Transfer is prepared for prime time,” Blackshear informed Cointelegraph.
It’s primetime for Transfer
Blackshear might have created Transfer for Fb’s Diem, however because the Mysten Labs founder admits, Diem was by no means the restrict of his ambition.
“While you’re engaged on a programming language like Transfer, Diem was our first candidate or buyer, however you need it to be broadly relevant,” mentioned Blackshear. “The factor that impressed me was then that I needed Transfer for use in all blockchains. I need it to be the business commonplace going ahead.”
Along with fellow Fb alumni, Blackshear created Mysten Labs. Group chief Even Cheng grew to become Mysten Labs’ CEO. George Danezis, who led programs analysis, venture lead Adeniyi Abiodun, and Kostas Chalkias, who Blackshear describes as “probably the most artistic individuals I’ve ever met,” joined them.
Blackshear provides, “I believe some individuals suppose 5 co-founders is rather a lot, however I really don’t know the way anyone does it with fewer, particularly on this house.”
The 5 based Mysten Labs in September 2021, and on Could 3, 2023, Mysten Labs launched Sui, a brand new layer-1 blockchain constructed on Transfer.
Sui wasn’t the primary Transfer-powered blockchain to return to market, nevertheless. Aptos, which launched in October 2022, holds that honor.
Like Sui, Aptos’ founders — Avery Ching and Mo Shaikh — beforehand labored at Fb.
A 3rd Transfer blockchain, Sei, can also be performing nicely. A have a look at CoinMarketCap reveals that Sei’s native token SEI has a wholesome market cap of $1.59 billion, only a fraction above Sui SUI at $1.58 billion, whereas the Aptos (APT) market cap is at present $3.06 billion.
Blackshear’s dream of Transfer being the business commonplace should be a way off, however Sui is way from alone, and it seems the competitors is not any barrier to its success. As Cointelegraph reported on Jan. 16, SUI is having fun with extraordinarily sturdy development. In a three-month interval, the entire quantity locked on the blockchain rose by 2,000%.
Cetus, Navi Protocol and Scallop Lend are among the many protocols which might be already contributing to its development. Solend, a significant lending protocol on Solana, plans to diversify with a lending platform on Sui.
Safety, accessibility and pace
The longer term for Sui and Transfer seems brilliant if their present type continues, and whereas non-Transfer chains aren’t going wherever — as Blackshear admits — he expresses a private perception that Transfer “is the best way ahead.”
“I believe sensible contract security is admittedly holding again broader adoption of crypto,” he provides.
For that cause, a language that cuts out frequent assault vectors has main benefits.
As for his high precedence for Sui, Blackshear cites accessibility. “We’re laser-focused on developer expertise. It’s what we care about essentially the most, the factor we get up desirous about every single day. The factor we obsess over is developer expertise.”
Seeking to the long run, Cointelegraph requested Blackshear what excited him most about the way forward for Sui. Because it transpires, the Mysten Labs founder is a little bit of a pace freak.
“One thing I’m actually enthusiastic about is we’re delivery the primary main improve to Sui consensus since our launch. It’s known as Mysticeti. Let me discuss at a excessive stage about what Mysticeti is doing. We’re actually targeted on being quick, and I imply quick when it comes to low latency. We expect throughput is necessary,” mentioned Blackshear. “We expect the factor that’s going to be differentiated in the long run is what chain is the quickest? When you’re constructing funds, when you’re constructing a sport, when you’re constructing something — all issues being equal, you’re going to select the chain that’s sooner.”
Blackshear explains that funds on Sui take 400 milliseconds, and decentralized exchanges take two to a few seconds. That doesn’t appear unreasonable, however Blackshear thinks it’s too sluggish.
200ms block time equivalents on @SuiNetwork is now conservative. Anticipate beneath that on mainnet with the brand new consensus replace, Mysticeti.

“With Mysticeti, we predict we will get that [decentralized exchange] time all the way down to about one second, which is the theoretical minimal and goes to be the quickest wherever,” he mentioned.
In keeping with Blackshear, the event interval can even be swift, with Mysticeti scheduled to launch within the first quarter of 2024.
A private journey
For these on the skin, the story of Transfer appears unlikely: A language created for a cryptocurrency that did not materialize is now having fun with a rebirth with three flourishing blockchain networks.
For Blackshear, it is usually a profoundly private journey. From his earliest days coding in Fb’s “infra [-structure] dungeon” — as Blackshear jokingly calls it — to taking the lead on a big venture equivalent to Diem was “a giant second of development for me.”

As for creating Mysten Labs, Blackshear says, “Being an entrepreneur may be very completely different than being a language designer and being a chief know-how officer[…] I’ve discovered rather a lot, and it retains me on my ft.”
Whereas the general public continues to be pretty new to Transfer, and its chains can nonetheless be thought of of their infancy, Blackshear has been engaged on the language for six years now. For him, Transfer and blockchain is about extra than simply strains of code.
He says: “There’s a variety of huge issues on the planet, and there’s a variety of attention-grabbing tech issues. I need to work in one thing that maximizes my affect and is significant to me. So for blockchain, the best way I give it some thought is that essentially, it’s a collaboration know-how […] On the most basic stage, that’s what conjures up me about blockchains.”
