The Graph (GRT) is a decentralized blockchain data indexing protocol aimed at enabling developers to efficiently access and query on-chain data. Leveraging technologies such as Subgraph, Indexer, and GraphQL, it delivers essential data services for Web3 applications like DeFi, NFT, and DAO. GRT serves as the native token of The Graph network, facilitating query fee payments, staking rewards, and network governance.

Ripple’s core operations rely on its underlying decentralized ledger, the XRP Ledger (XRPL)—an open-source blockchain architecture specifically designed for financial settlement. Unlike Bitcoin’s PoW or Ethereum’s PoS, XRPL utilizes the unique Ripple Protocol Consensus Algorithm (RPCA). Through a selected set of validator nodes, the network reaches agreement on transaction ordering within seconds, achieving ultra-fast settlement speeds and minimal energy consumption.

The core logic of Layer 2 (L2) lies in decoupling the execution layer from the settlement layer to achieve an exponential leap in throughput. As the dominant technical paradigm of L2, Rollups bundle hundreds or thousands of transactions off-chain, submitting only compressed summary data or fraud/validity proofs to the Ethereum mainnet. This "off-chain execution, on-chain settlement" mechanism allows L2s to inherit the mainnet's financial-grade security while reducing transaction costs to mere cents, effectively breaking the blockchain "trilemma" of decentralization, security, and high performance.

Jupiter is a decentralized exchange aggregation protocol built on the Solana network. Its primary objective is to consolidate liquidity from multiple decentralized trading platforms and provide users with more efficient asset swap routes. Through smart routing algorithms, Jupiter can identify the most favorable pricing across different liquidity pools and protocols. By dynamically selecting optimal execution paths, the protocol improves trading efficiency while reducing slippage.

Polymarket is a blockchain-based decentralized prediction market platform where users express views on future events by trading “yes” or “no” outcome shares, with prices commonly interpreted as implied market probabilities. Through smart contracts and stablecoin settlement, Polymarket enables a permissionless, non-custodial, and transparent mechanism for trading information, and is widely regarded as an important part of the emerging InfoFi landscape.
