Instead, the industry has entered an era of specialization, where each blockchain optimizes for a specific dimension.<\/p>\n\n\n\n<p>Below are four representative public blockchains:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>Bitcoin: Digital Gold<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Consensus Mechanism<\/strong>: Proof of Work (PoW)<\/li>\n\n\n\n<li><strong>Smart Contracts<\/strong>: Minimal, non-Turing complete<\/li>\n\n\n\n<li><strong>Block Time<\/strong>: ~10 minutes<\/li>\n\n\n\n<li><strong>Throughput<\/strong>: ~7 TPS<\/li>\n\n\n\n<li><strong>Finality<\/strong>: ~60 minutes (6 confirmations)<\/li>\n<\/ul>\n\n\n\n<p><strong>Design Philosophy<\/strong>: Bitcoin is the original blockchain application. Its design prioritizes minimalism and absolute security. It does not aim to support complex smart contracts\u2014it focuses on one thing: securely recording value transfers.<\/p>\n\n\n\n<p><strong>Core Strengths<\/strong>: Trust is established through real-world energy expenditure (computational work). Attacking the network would require controlling over 51% of total hash power, making it extremely costly. This makes Bitcoin the most secure blockchain network to date.<\/p>\n\n\n\n<p><strong>On-chain Reality<\/strong>: Roughly 60% of BTC has not moved in over a year, reinforcing its role as a <strong>store of value<\/strong> rather than a payment system. In the blockchain ecosystem, Bitcoin serves as &#8220;<strong>digital gold&#8221; and a trust anchor<\/strong>.<\/p>\n\n\n\n<p><strong>Limitations<\/strong>: Low speed, high energy consumption, and lack of support for complex applications.<\/p>\n\n\n\n<ol start=\"2\" class=\"wp-block-list\">\n<li>Ethereum: Decentralized Application Platform<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Consensus Mechanism<\/strong>: Proof of Stake (PoS, after <em>The Merge<\/em> in 2022)<\/li>\n\n\n\n<li><strong>Smart Contracts<\/strong>: Turing-complete<\/li>\n\n\n\n<li><strong>Block Time<\/strong>: ~12 seconds<\/li>\n\n\n\n<li><strong>Throughput<\/strong>: ~15\u201330 TPS (Layer 1), thousands TPS via Layer 2<\/li>\n\n\n\n<li><strong>User Confirmation<\/strong>: ~12 seconds; <strong>Finality<\/strong>: ~13 minutes<\/li>\n<\/ul>\n\n\n\n<p><strong>Design Philosophy<\/strong>: Ethereum introduced smart contracts at scale, transforming blockchain from a &#8220;transaction ledger&#8221; into a <strong>programmable global computer<\/strong>. Developers write code in Solidity and deploy it on the Ethereum Virtual Machine (EVM).<\/p>\n\n\n\n<p><strong>Core Strengths<\/strong>: Ethereum has the largest decentralized application ecosystem, including DeFi, NFTs, and DAOs. Its architecture is evolving, with the mainnet increasingly acting as a <strong>settlement and data availability layer<\/strong>, while execution is offloaded to Layer 2 solutions such as Arbitrum and Optimism.<\/p>\n\n\n\n<p><strong>On-chain Reality<\/strong>: Ethereum consistently holds over 50% of the total value locked (TVL) in DeFi, making it the de facto standard for decentralized finance.<\/p>\n\n\n\n<p><strong>Limitations<\/strong>: High and volatile gas fees on Layer 1 (transactions can cost tens of dollars during peak periods). Its fully transparent ledger model can also pose challenges for enterprise privacy and regulatory compliance.<\/p>\n\n\n\n<ol start=\"3\" class=\"wp-block-list\">\n<li>Solana: High-Performance Execution Layer<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Consensus Mechanism<\/strong>: PoS + Proof of History (PoH)<\/li>\n\n\n\n<li><strong>Smart Contracts<\/strong>: Turing-complete with parallel execution (Sealevel engine)<\/li>\n\n\n\n<li><strong>Block Time<\/strong>: ~400 milliseconds<\/li>\n\n\n\n<li><strong>Throughput<\/strong>: ~2,000\u201310,000 TPS (theoretical peak ~65,000 TPS)<\/li>\n\n\n\n<li><strong>Finality<\/strong>: ~1\u20132 seconds<\/li>\n<\/ul>\n\n\n\n<p><strong>Design Philosophy<\/strong>: Solana follows a &#8220;monolithic chain&#8221; approach, aiming to handle everything at Layer 1 instead of relying on Layer 2 scaling. Its key innovation, Proof of History, acts as a cryptographic clock that allows nodes to agree on transaction order without constant communication.<\/p>\n\n\n\n<p><strong>Core Strengths<\/strong>: Through parallel execution (similar to multi-core CPUs), transactions that do not conflict can be processed simultaneously. This enables high-performance applications such as order book exchanges and high-frequency trading.<\/p>\n\n\n\n<p><strong>On-chain Reality<\/strong>: Transaction fees are typically below $0.01, and block speeds far exceed Ethereum Layer 1, making Solana a preferred choice for high-frequency trading and on-chain gaming.<\/p>\n\n\n\n<p><strong>Limitations<\/strong>: High hardware requirements for validators, past network instability incidents, and a fully transparent ledger that may not suit enterprise privacy needs.<\/p>\n\n\n\n<ol start=\"4\" class=\"wp-block-list\">\n<li>BenFen Chain: Real-World Payment Infrastructure<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Consensus Mechanism<\/strong>: DAG-enhanced Proof of Stake<\/li>\n\n\n\n<li><strong>Smart Contracts<\/strong>: Move language with formal verification<\/li>\n\n\n\n<li><strong>Block\/Confirmation Time<\/strong>: Sub-second (&lt;0.5s)<\/li>\n\n\n\n<li><strong>Throughput<\/strong>: Tens of thousands TPS<\/li>\n\n\n\n<li><strong>Finality<\/strong>: &lt;0.5 seconds<\/li>\n<\/ul>\n\n\n\n<p><strong>Design Philosophy<\/strong>: <a href=\"https:\/\/www.benfen.org\/\">BenFen Chain<\/a> is a next-generation public blockchain focused on <strong>stablecoin payments and real-world assets (RWA)<\/strong>. Instead of aiming to be a general-purpose chain, it focuses on a single core question: <em>How can stablecoins be as usable on-chain as fiat is in the real world?<\/em><\/p>\n\n\n\n<p><strong>Core Features<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Move Language<\/strong>: Compared to Solidity, Move treats digital assets as <em>resources<\/em> that cannot be duplicated or destroyed arbitrarily, with formal verification providing mathematically provable security\u2014critical for stablecoins and RWA.<\/li>\n\n\n\n<li><strong>Native Stablecoin (BUSD)<\/strong>: Minted 1:1 via cross-chain bridges from USDT\/USDC. Users can pay gas fees directly in BUSD without holding the native token (BFC). A gas sponsorship mechanism enables near <strong>gasless user experience<\/strong> in many cases.<\/li>\n\n\n\n<li><strong>Sub-second Finality<\/strong>: DAG-based consensus delivers &lt;0.5s latency and high throughput.<\/li>\n\n\n\n<li><strong>Privacy Payments<\/strong>: Powered by FAST MPC (multi-party computation) and key sharding, enabling <strong>default privacy with selective disclosure<\/strong>\u2014allowing enterprises to protect sensitive data while remaining auditable.<\/li>\n\n\n\n<li><strong>zkLogin<\/strong>: Users can generate on-chain accounts and sign transactions via Google\/Apple accounts, eliminating the need for private key or mnemonic management and significantly lowering Web3 onboarding barriers.<\/li>\n<\/ul>\n\n\n\n<p><strong>Ecosystem<\/strong>: BenFen Chain is building a stablecoin-centric ecosystem focused on real-world payments and RWA use cases. Currently, the ecosystem is centered around user-facing applications such as BenPay, which enable a range of practical functions\u2014including stablecoin payments (via card integrations), asset swaps, cross-chain transfers, and on-chain earning opportunities.

Modifying a historical block requires rewriting all subsequent blocks and obtaining a majority of the network&#8217;s computing power or staking rights. On large public chains like Bitcoin and Ethereum, this is economically and computationally impractical.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span><i class=\"fas fa-arrow-right\"><\/i><\/span>Q2: Is decentralization always more secure? <\/h3>\n\n\n\n<p>Not entirely. Decentralization improves resistance to censorship and tolerance to single points of failure, but risks such as code vulnerabilities, lost private keys, and smart contract attacks still exist. Security is a combined result of &#8220;decentralization + code quality + user habits.&#8221;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span><i class=\"fas fa-arrow-right\"><\/i><\/span>Q3: How can ordinary people participate in blockchain? <\/h3>\n\n\n\n<p>If you are a beginner, you can start with mainstream wallets or trading platforms; you can also choose next-generation infrastructure like BenFen, which lowers the barrier to entry through mechanisms like zkLogin, eliminating the need for complex private key management.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span><i class=\"fas fa-arrow-right\"><\/i><\/span>Q4: Why are blockchain transfers sometimes slow and expensive? <\/h3>\n\n\n\n<p>The cost (Gas) and confirmation speed of blockchain transfers are essentially determined by the supply and demand of block space. When network transaction demand increases, users need to pay higher fees to compete for limited block packaging opportunities, thus obtaining faster confirmations. Furthermore, differences in the architectural design of different blockchains (such as block size, block time, and parallel processing capabilities) also significantly affect fee levels. For example, Bitcoin transaction fees can reach tens of dollars during peak periods, while high-performance networks like Solana can typically maintain lower fees.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span><i class=\"fas fa-arrow-right\"><\/i><\/span>Q5: With so many public chains, will they unify in the future? <\/h3>\n\n\n\n<p>No. Different public chains have different design trade-offs (security, speed, decentralization, cost), and no single chain can achieve the best simultaneously. The future trend is multi-chain coexistence + cross-chain interoperability, with each chain focusing on its own specific area.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\"><span><i class=\"fas fa-arrow-right\"><\/i><\/span>Risk Disclaimer <\/h2>\n\n\n\n<p>This content is for educational and informational purposes only and does not constitute investment, legal, or financial advice.
