What Is Sui Crypto? A Beginner's Guide For Crypto Investors
Sui is a Layer-1 blockchain designed to optimize speed, scalability and low transaction costs. Officially launched in 2023, Sui runs decentralized apps and play-to-earn games quickly and smoothly, giving users a streamlined experience.
This guide explains what makes Sui unique, how it works and why it's gaining traction among crypto investors and developers.
Mysten Labs, a team comprised of former Meta engineers, built Sui. The Layer-1 blockchain uses Move, a smart-contract programming language and unique object-based model, to process transactions in parallel. This leads to faster confirmation times and supports high-throughput applications like gaming, NFTs and DeFi.
The network's native token, SUI, is used to pay transaction fees, secure the network through staking and vote on governance decisions. Developers and users are drawn to Sui's ability to run advanced, data-heavy apps quickly and smoothly, making it a promising platform for building next-generation decentralized apps.
Sui was created by former Meta engineers who worked on the Diem blockchain project. Led by CEO Evan Cheng, the team built a faster, more efficient Layer-1 network and developed the Move programming language to simplify building decentralized apps.
By treating each asset as a separate object, Sui speeds up transactions and avoids delays tied to account balances. This design makes it attractive to developers and institutions looking for performance and security.
Unlike traditional blockchains, Sui runs on a unique architecture that allows it to process many transactions simultaneously rather than lining them up in a strict order. It does this by focusing on individual pieces of data, called objects, rather than entire accounts. Two transactions can be processed in parallel if they don't touch the same object. This makes Sui much faster and more scalable than blockchains that rely on every validator reviewing every transaction.
Smart contracts on the network are written in Move, a programming language also developed by Meta. Move allows developers to define how assets are created, transferred, and updated as programmable objects. These objects operate independently, making it easier to process many transactions simultaneously. Validators, also known as authorities, manage the network using a system that ensures speed and security.
SUI is Sui's native token. It is used to pay transaction fees, secure the network through staking and participate in governance. With a total capped supply of 10 billion tokens, SUI was designed to promote long-term economic sustainability, avoiding the rapid inflation or speculation in many other crypto projects. Importantly, no airdrops were offered at launch, prioritizing long-term stability over short-term hype.
As a whole, the network operates on a delegated proof-of-stake model. Users can stake their SUI with validators to help secure the system and earn rewards, which are distributed every 24 hours, including gas fees and protocol subsidies. SUI holders also have governance rights, allowing them to vote on network upgrades and proposals. A unique storage fund collects user fees to cover long-term data costs, reward validators and reduce the circulating supply of SUI, giving the token deflationary traits. Validator rewards are based strictly on stake size, with staking pools using exchange rates to compound earnings over time automatically.
Currently, Sui is working to implement 'SIP-39', which lowers the barrier to becoming a validator by focusing on voting power instead of a fixed token minimum. This opens the network to more participants and strengthens decentralization while maintaining economic security and validator accountability.
Sui differentiates itself from other Layer-1 blockchains with high velocity, low fees, and an object-based data model that allows parallel transactions. Unlike Ethereum's account-based architecture, which processes transactions linearly and can become congested, Sui handles unrelated transactions independently. Because Sui uses the Move programming language instead of Solidity, it offers developers greater control over assets, although Move is still less widely adopted at this time.
Compared to Solana, which is known for speed but has faced reliability issues and high validator hardware demands, Sui offers a more accessible and potentially more stable alternative. Unlike Cardano, which takes a slower, research-driven upgrade approach, Sui focuses on real-time performance and developer usability. These design choices position Sui as a competitive option for building scalable, next-generation applications.
Due to its smaller validator set, Sui is less decentralized than networks like Ethereum or Cardano, but it is actively working to improve this. Initiatives like SIP-39, which base validator eligibility on voting power instead of fixed token amounts, aim to lower entry barriers and encourage broader participation. Sui is expected to support more decentralization and stronger on-chain governance as these features roll out.
Sui is rapidly becoming the go-to platform for bitcoin-based assets and decentralized finance. OKX recently launched xBTC, a new type of bitcoin token, and chose Sui as one of the first blockchains to support it. bitcoin-backed assets make up over 10% of all the value locked in Sui, showing strong growth in this area.
DeFi continues to excel on Sui by moving into real-world asset investing through a new Open Market Group partnership. This lets users create unique tokens called Soulbound Tokens, which give them access to RWAs like property or other assets that earn rewards. Sui is also making waves in gaming. For example, the game XOCIETY teamed up with Adidas to launch limited-edition NFT skins that players can use in the game or trade.
Sui's future is bright as it continues to attract developers, institutions and ecosystem partners. Major initiatives like OKX's xBTC integration, the growth of Bitcoin-backed assets, and partnerships in RWA investing signal growing confidence in the network. Upcoming improvements to decentralization, such as the rollout of SIP-39, aim to make validator participation more accessible and strengthen the network's resilience.
While the recent Cetus exchange hack raised concerns, Sui's rapid response demonstrated its ability to protect users. Validators and ecosystem partners froze $163 million of the $223 million stolen, showing effective crisis coordination and network control. Blockchain security firm Dedaub identified the bug and outlined fixes, helping bolster confidence in future safeguards. Despite the incident, it has led to renewed focus on improving security and transparency, positioning Sui to emerge stronger and more prepared for institutional growth ahead.
Bottom Line
Sui is quickly becoming a key player among emerging Layer-1 blockchains. Its unique object-based infrastructure and the Move programming language make it a go-to platform for DeFi, gaming, and NFTs. The ecosystem is expanding and fueled by RWA integrations and BTC-backed DeFi solutions.
Despite challenges like the Cetus hack, Sui's swift and professional response highlighted its strong coordination and security focus. With upgrades like SIP-39 to improve decentralization and growing institutional partnerships, Sui is well-positioned as a serious contender in the next wave of blockchain innovation.

Gen Z men are still obsessed with Pokémon cards—using ‘boy math' to argue that they'll beat Nvidia stock and the S&P 500. But there's a catch
Pokémon and sports trading cards are outperforming the S&P 500 with upwards of 46% annual returns, and it's driving mania among Gen Z and Millennial men to collect top cards. While most fans aren't getting rich off a reselling side gig, there's no sign the boom is letting up—especially with big names like Logan Paul joining in on the frenzy. Gen Z and Millennials are in agreement: their obsession with Pokémon may never let up. Despite the Japanese franchise nearing its 30-year anniversary, young men in particular continue to be on a lifelong mission to 'catch 'em all'—and are spending hundreds, sometimes even millions of dollars, collecting trading cards. Part of the 'boy math' is that investing in cards could yield significant returns, and there might be some truth to the matter. Pokémon cards have seen the largest long-term increase in value among all card categories: up 3,261% over 20 years, according to data provided to Fortune from Card Ladder. Even looking at a one-year investment, the average Pokémon card is increasing at nearly 46%—a pace far exceeding hot stocks like Nvidia so far in 2025 or the S&P 500's average 12% annual return rate. While cards have to be rare and in pristine condition to make significant profit, the industry frenzy has left the shelves of retailers like Walmart and Target bare—and even caused some stores to enact limits or pauses on selling altogether. And online, it's pushing the resale market to new heights. Users on eBay searched for 'Pokemon' nearly 14,000 times per hour in 2024, according to Adam Ireland, VP and GM of global collectibles at eBay. And pairing the Pokémania with continued demand in the sports card world (thanks to athletes like Caitlin Clark and Michael Jordan), it's created a perfect storm of opportunity for the trading card industry. The total gross value of cards on eBay has increased for nine consecutive quarters. This embedded content is not available in your region. 'The trading card hobby has entered a new era, driven by technology, innovation, community, and a great balance of modern creativity–with new sets, storylines and characters–alongside good old nostalgia,' Ireland tells Fortune. No other influencer may have driven continued interest in Pokémon cards in particular than Logan Paul. The YouTuber, who is also known for his ventures into professional wrestling, boxing, and entrepreneurship, has spent millions of dollars purchasing cards—and then profiting off the millions of views generated from his content. 'Nostalgia + business = the new art,' he wrote on social media after spending $200,000 on cards. 'These things are appreciating like crazy as collectibles are becoming very low supply, high demand art pieces.' Logan Paul wearing a Charizard Pokemon card chain as he entered the ring for a 2021 boxing match against Floyd Mayweather. In 2022, he broke a Guinness World Record for the most expensive Pokémon trading card sold at a private sale with the purchase of a PSA Grade 10 (essentially perfect condition) Pikachu Illustrator card for $5.275 million. 'This card cost me more than my ranch. My 84-acre ranch,' Paul said at the time. Other social platforms, including TikTok, are full of content creators who have dedicated their lives to the purchasing, opening, and reselling of cards. But for some, the joy of collecting or making a profit doesn't work out as much as planned, with a recent call into Dave Ramsey's personal finance vodcast showing just how bad the obsession is gotten for some young men. 'I messed up big. I went behind my pregnant wife's back and racked up $26K in credit card debt in four months,' the caller said. 'What did you jack up $26K on?' Ramey asked. 'Pokemon cards—trying to buy a bunch and sell them online, but it didn't work out.' Like other collectables, trading cards can be considered a 'commodity' and even art, according to Jason Howarth, SVP of marketing and athlete relations at Panini America, a sports card company. But whether to consider it a true investment opportunity depends largely on your intentions. 'For some people, they (collect) because they view it as an investment. Others do it for the pure fun of it,' he says. By and large, most collectors are not going so off the deep end and being overly financially irresponsible, and instead see the hobby as a guilty pleasure. That includes Ryan Hoge, the president of PSA, one of the biggest companies that evaluates the condition and authenticity of trading cards. He said he personally has tens of thousands of cards, but like many, he enjoys collecting them, even if they are stored up in a closet. 'I think sometimes people want to break from the digital, and this is a good outlet for it,' Hoge tells Fortune. And not only do you get to hold something in your hand, but you also get to interact with a community of like minded people that have similar interests.' Last month, nearly 125,000 fans attended Fanatics' (which owns trading card company Topps) second annual convention centered around all things sports and collectibles. And the event notably saw influencer and former gymnast Livvy Dunne purchase a card of her professional baseball player boyfriend for $2,850. The National Sports Collectors Convention, which also brings over 100,000 fans, is set for later this summer outside of Chicago. While the trading card industry was on the brink of extinction following overproduction in the 1990s, it's since recovered and is booming. Sports cards bring in $1 billion in annual revenue for manufacturers and retailers, according to The Athletic. Pokémon alone brought in a similar number, and was the only toy to surpass $1 billion in sales last year, says Circana data. And even though over 75 billion Pokémon cards have been produced (enough to wrap around Earth end-to-end 165 times), demand is still skyhigh, according to Barry Sams, vice president of game development and community engagement at The Pokémon Company International. 'With explosion in demand, we're printing at maximum capacity to deliver the greatest amount of cards possible to fans for current expansions while ensuring we maintain quality standards,' he tells Fortune. 'Those who grew up with Pokémon now have children of their own to share that passion with, and oftentimes, that means revisiting old Pokémon card collections and recreating fond childhood memories as a parent.' The opportunity within the card industry is causing retailers like GameStop to pay greater attention. The electronics store said in the first quarter of 2025, collectibles, such as Pokémon and sports cards, made up 29% of the company's sales—outselling video game software. 'We're focusing on trading cards as a natural extension of our existing business,' GameStop CEO Ryan Cohen said at the company's annual shareholder meeting last month. 'The trading card market, whether it's sports, Pokémon or collectibles, is aligned with our heritage. It fits our trade and model. It appeals to our core customer base. And it's deeply embedded in physical retail.' The industry continues to fascinate even world leaders. During this year's Easter Egg Roll on the South Lawn of the White House, President Donald Trump was seen with a graded trading card that depicted the assassination attempt on him last year. And in a recent meeting with a young student, Pope Leo XIV didn't shy away from the trading card frenzy and was more than happy to sign a 'Popplio' Pokemon card. 'It doesn't matter how old you are, when you get a pack of cards in your hand, the first thing you want to do is rip it open and you hope that you're going to get that hot rookie, or you're going to get a player from your favorite team,' says Panini's Howarth. 'If any one of those things happens, you're ecstatic.'

Bear of the Day: DXC Technology (DXC)
DXC Technology (DXC) has struggled to gain traction in recent years, as persistent revenue declines and a sluggish business transformation have weighed heavily on both its fundamentals and its stock price. Once a major player in IT services, the company has seen its sales fall steadily, leading to stagnation and underperformance in a sector that's otherwise full of innovation and growth. The stock has dropped nearly 30% year-to-date and is down more than 65% since 2021, reflecting a prolonged period of investor disappointment. Analyst sentiment has continued to deteriorate as well, pushing DXC down to a Zacks Rank #5 (Strong Sell) rating. While management has laid out a strategy to pivot away from legacy infrastructure services and toward higher-growth digital and cloud offerings, the turnaround has been slow to materialize. There may be potential in the longer term, but for now, the company remains in a difficult position. Until investors see clear signs of stabilization and renewed growth, DXC is a stock best left on the sidelines. Image Source: Zacks Investment Research DXC Technology's prolonged decline in revenue continues to be a major overhang for the stock. Annual sales have dropped significantly—from approximately $22 billion in 2018 to just $12.8 billion over the trailing twelve months, a nearly 42% decline that reflects the company's struggle to transition away from its legacy business model. Unfortunately, the outlook doesn't suggest a turnaround is imminent. Analysts expect revenue to decline another 4.5% in the current fiscal year, followed by an additional 2.8% decline next year, indicating that demand for DXC's core offerings remains under pressure despite management's transformation efforts. Adding to the bearish case, analyst sentiment around profitability has worsened. Over the past 60 days, consensus earnings estimates have been revised downward—current year EPS estimates have fallen by 7.9%, while next year's projections have dropped by 9.3%. This steady erosion of expectations signals broad skepticism among analysts and institutional investors about the company's near-term ability to stabilize or grow earnings. Image Source: Zacks Investment Research Technical weakness is compounding DXC Technology's fundamental challenges, with selling pressure intensifying in recent sessions. On Friday, the stock was hit particularly hard, closing sharply lower with bearing mometnum pickin up. Shares are now hovering just above a critical support level near $14.20. If DXC fails to hold this level, it could trigger a technical breakdown, opening the door to another wave of selling. A decisive move below this support zone would confirm the downtrend and could send the stock cascading to new multi-year lows. With no strong bullish catalysts in sight, the path of least resistance appears to be lower unless a significant reversal develops soon. Image Source: TradingView Given its declining fundamentals, weakening technical setup, and continued negative analyst sentiment, DXC remains a high-risk name with limited near-term upside. Until the company proves it can stabilize revenue and execute its transformation strategy more effectively, investors are likely better off staying on the sidelines.
