SHARD-AWARE ARCHITECTURE
Core Technical Capabilities
We build production-ready oracle protocols that leverage NEAR's unique sharding to deliver high-throughput, low-latency data feeds with enterprise-grade reliability.
01
Shard-Aware Data Aggregation
Our oracles are designed from the ground up for NEAR's Nightshade sharding. We implement cross-shard communication patterns to aggregate data with sub-second finality, eliminating bottlenecks for high-frequency DeFi applications.

Secure Multi-Source Validation
We integrate data from 15+ premium and decentralized sources (Chainlink, Pyth, API3) with a proprietary fraud-detection engine. All aggregation logic is formally verified and audited to prevent manipulation.

Business Outcomes for Your Protocol
We translate NEAR's shard-aware architecture into concrete, measurable advantages for your protocol. Our development process is engineered to deliver specific performance, security, and scalability outcomes.
01
Sub-Second Cross-Shard Data Finality
We architect your oracle to leverage NEAR's Nightshade consensus, enabling data attestations to finalize in under 1 second across shards. This eliminates the latency bottlenecks of traditional cross-chain oracles, making your DeFi or gaming protocol truly responsive.

02
Gas-Optimized, Shard-Local Execution
Our smart contracts are deployed with shard locality in mind, ensuring data feeds are processed and validated within a single shard where possible. This reduces inter-shard communication overhead, cutting your protocol's gas costs by up to 40% compared to a naive implementation.

Formally Verified Core Contracts
The heart of your oracle's logic—price calculation, aggregation, and attestation—undergoes formal verification using K-framework or similar tools. We provide mathematical proof of correctness for critical state transitions, a non-negotiable standard for protocols securing >$1M in TVL.

Why a Custom Protocol Outperforms Generic Oracles
Build vs. Adapt: The Shard-Aware Advantage
A direct comparison of the time, cost, and technical outcomes between building a custom shard-aware oracle in-house versus partnering with Chainscore Labs for a tailored solution.
| Key Factor | Build In-House | Adapt Generic Oracle | Chainscore Shard-Aware Protocol |
|---|---|---|---|
Time to Production | 6-12+ months | 2-4 months | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $50K - $150K | $80K - $200K |
NEAR Shard Architecture Optimization | Requires deep R&D | Not possible | Built-in design |
Cross-Shard Data Finality | Custom implementation risk | Network-level latency | Sub-2 second guarantees |
Security & Audit Overhead | High (unaudited, custom code) | Medium (depends on provider) | Low (pre-audited patterns, optional full audit) |
Ongoing Maintenance Team | 2-3 full-time engineers | 1-2 engineers + vendor management | Optional SLA with our team |
Scalability with Shard Growth | Manual re-architecture required | Performance degrades | Automatically scales with network |
Total Cost of Ownership (Year 1) | $400K - $800K+ | $150K - $300K | $120K - $250K |
Guaranteed Uptime SLA | Your responsibility | Defined by provider (often <99.5%) | 99.9% Enterprise SLA available |
