How I think about "security":The goal is to minimize the divergence between the user's intent, and the actual behavior of the system."User experience" can also be defined in this way. Thus, "user experience" and "security" are thus not separate fields. However, "security" focuses on tail risk situations (where downside of divergence is large), and specifically tail risk situations that come about as a result of adversarial behavior.One thing that becomes immediately obvious from the above definition, is tha ...

Prediction: 2 Popular Cryptocurrencies That Could Underperform in 2026
Yahoo Finance· 2026-02-20 18:25
Many cryptocurrencies lost their luster over the past year. High Treasury yields, expectations for slower monetary easing, and waning institutional interest all chilled the market, while leveraged liquidations triggered incessant waves of profit-taking. Some of those cryptocurrencies -- especially "blue chip" ones like Bitcoin (CRYPTO: BTC) and Ethereum (CRYPTO: ETH) -- could bounce back if the market warms up again this year. However, two other popular ones -- XRP (CRYPTO: XRP) and Dogecoin (CRYPTO: DOGE ...
Bitcoin vs. Ethereum: Which Is the Smarter Buy for 2026 and Beyond?
Yahoo Finance· 2026-02-20 16:30
Core Insights - Bitcoin and Ethereum have both experienced a 30% decline in value over the past year due to high Treasury yields, expectations of slower monetary easing, reduced institutional interest, and leveraged liquidations [1] Group 1: Differences Between Bitcoin and Ethereum - Bitcoin utilizes a proof-of-work (PoW) consensus mechanism, requiring significant energy for mining, while Ethereum transitioned to a proof-of-stake (PoS) mechanism in 2022, allowing for staking and the development of decentralized applications [2] - Bitcoin has a supply cap of 21 million tokens, with nearly 20 million already mined, and undergoes a "halving" every four years, enhancing its scarcity value [3] - Ethereum has a circulating supply of 121.6 million tokens without a maximum limit, with new tokens created through staking and excess tokens periodically burned to manage supply [4] Group 2: Investment Considerations - Both Bitcoin and Ethereum are considered more conservative investments compared to smaller altcoins, supported by their own spot price ETFs; however, Ethereum is favored for its clearer growth catalysts [5] - The Ethereum Foundation plans significant upgrades to enhance scalability, reduce network congestion and gas fees, and improve overall efficiency, which may strengthen Ethereum's position among developer-oriented blockchains [6]
Is XRP a Millionaire-Maker? Here's What Has to Go Right
Yahoo Finance· 2026-02-19 20:50
Core Insights - XRP, the native token of the XRP Ledger, has shown significant appreciation since its inception, with an investment of $10,000 in 2013 now worth $2.35 million, raising questions about its future potential for new investments [1] Group 1: XRP's Background and Usage - XRP was created by Ripple Labs in 2012 and is designed as a bridge currency for facilitating cross-border transactions, claiming advantages over traditional SWIFT transfers in terms of cost, speed, and security [2] - The entire supply of XRP, totaling 100 billion tokens, was pre-minted and cannot be mined or staked like Bitcoin or Ethereum [1] Group 2: Regulatory Challenges - In 2020, the SEC filed a lawsuit against Ripple, alleging that the sale of XRP constituted the sale of unregistered securities, leading to the delisting of XRP from several major exchanges [3] - The lawsuit concluded in August 2023 with a favorable ruling for Ripple, stating that XRP was not an unregistered security when sold to retail investors, resulting in the relisting of XRP on top exchanges [4] Group 3: Long-term Viability and Challenges - Despite the positive regulatory outcome, critics argue that XRP lacks sufficient long-term catalysts for growth, particularly with the rise of stablecoins that can directly facilitate cross-border transactions without needing XRP [5] - The XRP Ledger's limitations in supporting smart contracts hinder its appeal for developers, although recent updates have introduced Ethereum-compatible sidechains [6] Group 4: Future Opportunities - Ripple's application for a U.S. bank charter and potential expansion into broader financial services could enhance XRP's transaction usage [7] - The introduction of new ETFs may attract institutional investors, especially as the cryptocurrency market recovers from its downturn [7]
