Iron Finance
Iron Finance was a decentralized finance (defi) protocol based on the Polygon blockchain. History Iron Finance was founded by anonymous developers as a fork of the Frax project. Its early investors included Mark Cuban. In June 2021, the value of the tokens plummeted to zero after crypto whales began liquidating their TITAN stakes at its peak value, causing the prices of both the IRON stablecoin and TITAN token to drop sharply. The situation worsened when the smart contract, the underlying code governing the stablecoin, temporarily malfunctioned which made impossible for holders to redeem their coins. Tokens IRON was an algorithmic stablecoin backed by 75 percent USDC and 25 percent TITAN. The Target Collateral Ratio (TCR) defined the ratio of USDC to $1 worth of IRON minted. The remaining value was provided by TITAN tokens at the prevailing price, requiring fewer tokens when TITAN's price was high. Users could redeem IRON for USDC and TITAN, with the Effective Collateral Ratio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decentralized Finance
Decentralized finance (often stylized as DeFi) provides financial instruments and services through smart contracts on a programmable, permissionless blockchain. This approach reduces the need for intermediaries such as brokerages, exchanges, or banks. DeFi platforms enable users to lend or borrow funds, speculate on asset price movements using derivatives, trade cryptocurrencies, insure against risks, and earn interest in savings-like accounts. The DeFi ecosystem is built on a layered architecture and highly composable building blocks. While some applications offer high interest rates, they carry high risks. Coding errors and hacks are a common challenge in DeFi. DeFi protocols exhibit varying degrees of decentralization, with truly decentralized protocols potentially acting as neutral infrastructure, while false decentralization leaves protocols open to manipulation and fraud or to being regulated as financial intermediaries. History Decentralized exchanges (abbreviated DEXs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polygon (blockchain)
Polygon (formerly Matic Network) is a blockchain platform which aims to create a multi-chain blockchain system compatible with Ethereum. As with Ethereum, it uses a proof-of-stake consensus mechanism for processing transactions on-chain. Polygon's native token is POL, an ERC-20 token which allows for compatibility with other Ethereum cryptocurrencies. It is operated by Polygon Labs. Polygon is a natively Layer-2 network that uses Ethereum as a base network. In particular, transactions are first validated inside Polygon and then periodically committed in a "checkpoint": a Merkle root of transaction hashes is committed to Ethereum's mainnet by using "Core contracts". Polygon runs various decentralized applications (dApps) such as Defi, DAOs, and NFTs. History The blockchain company Polygon was originally known as Matic Network. The Matic Network was launched in 2017 by four software engineers: Jaynti Kanani, Sandeep Nailwal, Anurag Arjun, and Mihailo Bjelic. In February 20 ...

Mark Cuban
Mark Cuban (born July 31, 1958) is an American businessman and television personality. He is the former principal owner and current minority owner of the Dallas Mavericks of the National Basketball Association (NBA) and co-owner of 2929 Entertainment. He is also one of the main "sharks" on the American Broadcasting Company, ABC reality television series ''Shark Tank''. As of May 2025, ''Forbes'' has estimated his net worth to be $5.7 billion. Born in Pittsburgh, Pittsburgh, Pennsylvania, Cuban was involved in ventures from a young age, from selling garbage bags to running newspapers during a strike. He graduated from the Kelley School of Business at Indiana University and embarked on a diverse business career that included founding MicroSolutions and Broadcast.com, both of which he sold at substantial profits. Cuban's investments span various industries, from technology and media to sports and entertainment. He has been a prominent figure in the NBA, known for his active involveme ...

Negative Feedback Loop
Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances. Whereas positive feedback tends to instability via exponential growth, oscillation or chaotic behavior, negative feedback generally promotes stability. Negative feedback tends to promote a settling to equilibrium, and reduces the effects of perturbations. Negative feedback loops in which just the right amount of correction is applied with optimum timing, can be very stable, accurate, and responsive. Negative feedback is widely used in mechanical and electronic engineering, and it is observed in many other fields including biology, chemistry and economics. General negative feedback systems are studied in control systems engineering. Negative feedback loops also play an integral role in maintaining the atmospher ...

TerraUSD
Terra was a blockchain protocol and payment platform used for algorithmic stablecoins. The project was created in 2018 by Terraform Labs, a startup co-founded by Do Kwon and Daniel Shin. It is best known for its Terra algorithmic stablecoin and the associated LUNA reserve asset cryptocurrency. In May 2022, the Terra blockchain was temporarily halted after the collapse of the algorithmic stablecoin TerraUSD (UST) and the cryptocurrency LUNA, an event that wiped out almost $45billion in market capitalization within a week. On January 21, 2024, the company filed for bankruptcy. Design Terra is a blockchain that leverages fiat-pegged stablecoins to power a payment system. For consensus, the Terra blockchain uses a proof-of-stake codesign. Several stablecoins are built atop the Terra protocol, including TerraUSD, which was the third largest stablecoin by market capitalisation before its collapse in May 2022. The Terra blockchain has a fully-functional ecosystem of decentra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
