# Filtercoin

*/Startups/Filtercoin*

## Startup Overview

This protocol defends open API endpoints by requiring sender-staked collateral to route inbound payloads. Rather than relying on traffic analysis or interactive puzzles, the system enforces a strict economic barrier at the gateway. Every incoming request must attach a programmable deposit to successfully reach the target server.

Platforms running public-facing APIs face constant floods of automated spam and sybil attacks. Conventional defenses like Cloudflare Turnstile, Akismet, and hashcash-based captchas attempt to filter these requests probabilistically, which often blocks valid traffic through false positives or degrades the user experience with mandatory friction.

Shifting the filter from heuristics to economics makes automated abuse financially unviable. Attackers forfeit their staked collateral upon submitting malicious payloads, rendering large-scale bot networks economically prohibitive. Meanwhile, the cryptographic staking and verification process executes entirely in the background, remaining completely invisible to legitimate senders.

## Startup Offer

**Proof**:
- Targeting high-volume RPC providers aiming to eliminate bot-driven API calls without serving captchas to legitimate developers.
- Designed to help decentralized social networks reduce infrastructure load by enforcing micro-stakes on inbound POST requests.
- Aiming to process enterprise API traffic with zero conversion drop-off by relying strictly on mathematical collateral rather than behavioral friction.
**Tiers**:
- Name: Developer Node · Price: ~$0.002–$0.005 per routed request · Inclusions: API payload filtering for up to 2 endpoints, real-time stake verification on a single chain, and standard rate-limiting designed for low-volume projects.
- Name: Production Gateway · Price: ~$150–$300/mo + ~$0.0008 per request · Inclusions: Protection for up to 20 endpoints, multi-chain collateral verification, dynamic stake-scaling during high traffic, and intended integration with major ingress providers like Cloudflare Workers.
- Name: Enterprise Routing · Price: ~$2,000–$4,500/mo base · Inclusions: Unlimited protected endpoints, dedicated relay nodes with guaranteed sub-50ms validation latency, custom collateral slashing conditions, and hands-on integration support.
**Guarantee**: Filtercoin guarantees sub-50ms latency overhead on payload validation and zero false-positive rejections for senders meeting your programmed stake thresholds; if an appropriately staked payload is incorrectly dropped by our relay, we refund 10x the monthly routing fee for that endpoint.
**Business Function**: ProvideService
**Objection Handlers**:
- Objection: Legitimate end-users do not have crypto wallets to stake collateral. Rebuttal: Filtercoin is designed to support relayer networks and account abstraction, allowing you or a verified sponsor to transparently stake on behalf of trusted users.
- Objection: Validating collateral on-chain will add unacceptable latency to our API. Rebuttal: Validation relies on edge-localized caching of staked addresses, aiming to add less than 50ms of overhead before passing the payload to your origin.
- Objection: A well-capitalized attacker could just stake the collateral and spam us anyway. Rebuttal: Filtercoin dynamically scales the required collateral per-sender during volumetric surges, making sustained Layer 7 attacks mathematically ruinous.
- Objection: We cannot afford the smart contract risk of taking custody of user funds. Rebuttal: Filtercoin reads staked or time-locked assets directly from major Layer-1 chains; neither you nor Filtercoin ever takes custody of the sender's collateral.

## Startup Proof Points

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**Pilot Goals**:
- A 14-day shadow deployment on a secondary API endpoint to prove edge-localized validation adds less than 50ms of latency before passing payloads to the origin.
- A 30-day active block pilot on a decentralized social network POST route to demonstrate dynamic collateral scaling during simulated traffic surges without dropping staked user payloads.
**Target Metrics**:
- target: less than 50ms latency overhead added per validated API request.
- aim: 100 percent elimination of un-staked Layer 7 volumetric spam traffic.
- target: zero false-positive rejections for senders maintaining programmed stake thresholds.
- before/after: from zero cost to attack the endpoint to a mathematically ruinous dynamic collateral requirement during traffic surges.
**Target Case Studies**:
- A high-volume Web3 RPC provider aiming to drop unauthenticated bot traffic by 95 percent while maintaining zero-friction access for properly staked developer accounts.
- A decentralized social network targeting a reduction in infrastructure hosting costs by enforcing micro-stakes on inbound POST requests to eliminate spam.
- An enterprise financial API seeking to replace behavioral captchas with mathematical collateral validation for continuous high-speed automated trading clients.
**Testimonial Targets**:
- VP of Engineering expressing relief that bot mitigation no longer requires serving captchas to legitimate API consumers.
- Lead Infrastructure Architect emphasizing the ease of edge-localized cache validation without taking custody of user funds.
- Chief Information Security Officer highlighting the effectiveness of dynamic stake-scaling during a simulated Layer 7 attack.

- Severity: high · Description: Smart contract vulnerabilities in the collateral staking layer allow attackers to drain the funds deposited by legitimate senders. · Mitigation Status: in-progress
- Severity: high · Description: Extreme price volatility in the collateral asset dynamically alters the cost of routing, inadvertently pricing out legitimate users or making spam economically viable. · Mitigation Status: unmitigated
- Severity: moderate · Description: The latency overhead required to verify on-chain collateral stakes before routing payloads violates the strict service-level agreements of enterprise API providers. · Mitigation Status: in-progress
