Billion-Dollar Crypto Trader Touts Launch of New DeFi Cryptocurrency, Says Solana Blockchain Far Outperforms Ethereum
Sam Bankman-Fried, CEO of Alameda Research and founder of cryptocurrency derivatives exchange FTX, says decentralized finance (DeFi) is promising, but has a ways to go before it’s ready for prime time.
Bankman-Fried is known for his exceptional trading skills, with Alameda Research handling approximately $1 billion in trades daily and ranking as one of the most profitable trading entities on BitMEX.
In a series of tweets, Bankman-Fried says DeFi is “hot, and exciting, and messy”, with the potential to power a financial ecosystem with inherent trust and without censorship. He believes the new blockchain Solana, which will host FTX’s new decentralized exchange (DEX) Serum, can address some potential issues facing DeFi applications that run on Ethereum.
“Anyone who’s used existing protocols has felt this: the frustration of waiting 5 minutes for a transaction before learning it failed because of something that happened after you sent it; seeing a estimated gas cost of $100 during peak times. It’s really holding back the space.
But it’s also where everything is. Most of the major apps and projects and aggregators and informational websites live on Ethereum, as does most of the community who built the space up. If you lose all of those, you sort of have nothing left. We’ve spent the last months immersing ourselves in the DeFi ecosystem. I’m incredibly grateful to everyone of you who helped teach us, entertained our ideas, and connected us. And especially to those who empowered and believed in us. And after drafts and experiments and revisions and feedback and iteration, we’re excited to tell you about what we’ve been working on. This is Project Serum.”
Solana launched its mainnet early this year, boasting the ability to process more than 50,000 transactions per second.
Bankman-Fried says the Solana blockchain will allow the decentralized exchange Serum to give users the experience they’re used to enjoying on centralized exchanges. Serum will utilize the new Solana-based token called SRM. The token will give holders discounts on trading fees and can be staked to help power the network.
Project Serum is a decentralized ecosystem built from the ground up to meet the world’s needs. Serum is fast, and it’s cheap, and powerful, and fully cross-chain compatible. And it’s truly, fully trustless.
Serum is built on the Solana blockchain. Solana can process 10,000 times as much as Ethereum; and it’s 1,000,000 times cheaper. And unlike many side chains, Solana is a fully fledged, decentralized blockchain with over 100 validators.
This allows Serum to have full central order limit books, with the familiar market, limit, and IOC orders; processing multiple times per second; all while being fully on chain. This is then combined with a powerful cross-chain protocol allowing for trustless and efficient tokenization and swaps, meaning that while living natively on Solana, Serum is interoperable on Ethereum.”
Bankman-Fried says both Serum and SRM will be rolling out in the next few weeks.
QEBR Management Discusses Authorization by Major Crypto Trading Exchanges to Offer Filecoin
NEW YORK, Aug. 4, 2020
NEW YORK, Aug. 4, 2020 /PRNewswire/ — QEBR (OTC:QEBR) today announced that several global crypto-trading platforms have announced their respective abilities to trade and store Filecoin. This gives strong third-party validation of Filecoin (FIL) as the cryptocurrency moves toward mainnet launch in the second half of 2020. QEBR previously announced that its internal software engineering team has made strong strides in developing a crypto environment that is highly efficient in mining FIL, with plans for multiple data centers around the world. These major blockchain trading exchanges include:
Coinlist conducted the $204 million Filecoin SAFT (Simple Agreement for Future Tokens) sale in 2017, which allowed 2,100 accredited investors from over fifty countries to invest in Filecoin. After the Filecoin mainnet launch, Coinlist is expected to support Filecoin’s trading as the primary distribution channel for the tokens.
Gemini is a digital currency exchange and asset insurance platform that allows customers to buy, sell, and store digital assets. Gemini was created by the Winklevoss twins, who own more than $1 Billion in cryptocurrency assets and have invested in many leading technology companies.
Coinbase Custody offers secure, institutional-grade offline custody storage solutions, insurance coverage, and stores over $8 Billion in crypto assets.
Anchorage announced that it will support Filecoin custody and unlocking contracts at mainnet launch. The company serves as a blockchain security and trading platform and has backing from companies such as Visa, Andreesen Horowitz, and Blockchain Capital.
Jun Liang, Chief Technology Officer of QEBR, stated, “The market validation of these highly-credible trading platforms gives QEBR even stronger faith in our Filecoin mining developments. For example, Gemini has a conservative approach to its platform, listing only five other assets: bitcoin, bitcoin cash, ether, Litecoin, and Zcash. Having Gemini and the Winklevoss twins also list Filecoin to their portfolio adds tremendous credibility to FIL’s future.
Liang continued, “QEBR deeply believes in the future of Filecoin and is making every effort to become a strong player in FIL mining. We expect to have mining operations around the world, with our first FIL mining operation in Thailand. This installation will be a gateway to projected strong demand in Malaysia, South Korea, the Philippines, Indonesia, and Japan.”
The Filecoin project is a decentralized storage system based in the cloud. Its InterPlanetary File System, or IPFS, requires FIL coins as payment to miners in exchange for storage space.
Filecoin, developed by Protocol Labs, is a decentralized storage network. The network is expected to give owners of unused storage a means to monetize their storage capacity. It is also expected to bring down the costs of storing data reliably. Given the large amounts of unused storage in data centers and hard drives around the world, a natural market exists for this service.
QEBR is the trading symbol for Virtual Medical International, Inc., a Nevada corporation. QEBR develops or acquires promising technology companies from around the world that specialize in data processing, warehousing, encryption, and analysis.
