What is Space and Time?

(Source:@SpaceandTimeDB)

Space and Time (SXT) is a decentralized Layer 1 blockchain that focuses on providing zero-knowledge proof (ZK-proof) data verification. As the first trust-free data warehouse for EVM, SXT Chain allows smart contracts to access historical, cross-chain, and off-chain data as if they were directly reading on-chain data, ensuring that the data is verified and cannot be tampered with.

The unique architecture of SXT lies in its data processing method. Data is not directly stored on the chain, but is updated through validators’ cryptographic commitments and recorded on the chain after these commitments are signed. These cryptographic commitments are similar to digital fingerprints, which can ensure that the structure and content of each data table are locked and tamper-proof. Through this method, Space and Time has established a highly verifiable and trust-minimized data management platform.

Core technology of Space and Time

The core technology of Space and Time is Proof of SQL, which is an innovative zero-knowledge proof protocol that can execute SQL queries off-chain and generate proofs to ensure that the query results are computed based on unaltered data. Smart contracts can securely make decisions based on these ZK-proof results.

The Prover node is responsible for monitoring query requests from EVM contracts and running SQL queries off-chain. These queries can come from the data tables of the SXT Chain or other indexed on-chain data. The Prover node executes SQL logic, generates zero-knowledge proofs, and ultimately returns the results back to the smart contract via ZK-oracle to ensure that the query is correct and tamper-proof.

The network architecture of SXT Chain

The network architecture of SXT Chain is divided into three main parts:

• Indexer node: responsible for extracting data from major public chains and converting it into SQL-compatible format to ensure the integrity of on-chain data.
• Prover node: processing the generation of ZK proofs and verifying query requests.
• Validator node: responsible for consensus confirmation of data and recording of encrypted commitments, ensuring the correctness of network data.

Data access and internet security

SXT Chain ensures the integrity and security of data during the writing process through a unique BFT consensus mechanism. When the data is indexed and submitted to SXT Chain, it undergoes consensus verification by Validator nodes and generates encrypted commitment records on the chain. Whether the data comes from Ethereum, Bitcoin, or other chains, SXT Chain can ensure its originality. In addition, all data queries are verified for correctness through Proof of SQL’s ZK proof, even the results of off-chain computations can be trusted by smart contracts to avoid potential risks from centralized data repositories.

Features of the operation of SXT Chain

• High-throughput data ingestion: SXT Chain supports high-speed data ingestion from blockchain, consumer applications, and enterprise data.
• Verifiable SQL queries: Verify large datasets queries through ZK-proof to ensure correct and unaltered results.
• Fast ZK proof generation: use GPU Prover nodes for high-speed computation to ensure instant verification results.
• On-chain data index: SXT Chain has currently indexed data from mainstream chains such as Ethereum, Bitcoin, Base, ZKsync, Sui, etc.
• Immutable database: The structure and content of the data table are encrypted and promised to be locked, ensuring that they cannot be easily altered.

Applications of Space and Time

• Cross-chain financial transactions: trustless cross-chain data access, such as querying real-time data from BNB Chain on Ethereum.
• Data-driven DeFi lending: Decentralized lending risk assessment based on historical credit records.
• Game Rewards: Instantly calculate player behavior and provide feedback rewards.
• Data-driven social application: instant data synchronization and query without centralized servers.

Token Economics of Space and Time

SXT is the native token of the Space and Time blockchain, and the token distribution structure of SXT is as follows:

• Community: 51.7% of the total supply, including 28.0% for community rewards, to incentivize ecosystem participants and expand the community network.
• Ecosystem Development: 23.7% allocation, mainly used to support protocol growth, infrastructure expansion, and cross-chain integration.
• Investors: accounting for 25.9% of the total supply, as a reward for early supporters and strategic partners.
• Team: 22.4% is allocated for incentivizing the core development team and long-term technical support to ensure the stable growth of the protocol.

The token distribution design aims to balance protocol growth, community participation, and long-term development potential, enabling all parties to benefit equally and jointly promote the ecological expansion of SXT, with primary use cases including:

• Network security and verification: Validators need to pledge SXT to participate in data verification and encrypted commitment updates, and obtain rewards through the execution of the Proof of SQL protocol.
• Data query payment: Users need to pay SXT as a fee when querying ZK-proof data.
• Staking and Penalty Mechanism: If a validator commits data manipulation, queries cannot be verified, or downtime occurs, the staked SXT will face partial or full penalty (slashing).
• Data Sheet Owner Incentives: Data providers can earn SXT rewards by uploading high-quality data to the chain and accepting queries, and can choose to delegate some of the rewards to Prover nodes to improve query efficiency.

Future Outlook of Space and Time

The future development of Space and Time focuses on expanding its cross-chain data access capabilities and plans to further optimize the speed of ZK-proof generation to support more real-time applications. At the same time, the team plans to integrate with more public chains and decentralized protocols to make data circulation more seamless and efficient. SXT will also gradually transition to community management through a decentralized governance model to ensure the long-term sustainable development of the network and maintain its decentralized nature.

Summary

Space and Time (SXT) is redefining the standards for data verification and cross-chain access, providing truly reliable and efficient data sources for smart contracts through zero-knowledge proof technology and trustless data repository architecture. With the integration of more chains and the realization of decentralized governance in the future, SXT will become an indispensable data infrastructure for Web3 applications.
