Understand FOC in one sentence\u003cc-146/\u003e

Filecoin on-chain cloud (FOC) is a brand new core functionality upgrade of Filecoin.

Upgrading the decentralized storage network to a programmable, verifiable, and automatically settling on-chain cloud platform.

The entire process of storage, verification, and payment is auditable on-chain.

Advantage 1 | Fully verifiable across the entire chain, bidding farewell to trust dependency

Utilizing PDP on-chain data possession proof, automatically verifying data integrity every 24 hours.

Billing is only calculated upon successful verification; automatic suspension occurs upon verification failure.

Content addressing + cryptographic proof, data is immutable and traceable

No need to trust a single service provider, fully auditable

Advantage Two | Smart Contract Driven, Fully Automated Process

Storage rules, payment logic, workflow written into smart contracts, automatically executed

Supports AI agents, unmanned systems for automatic storage, retrieval, and payment

Adapted to Web3, DePIN, AI training, and other no-human business scenarios

No human intervention, reducing errors and operational costs

Advantage Three | Decentralization + High Redundancy, Safe and Stable

Data distributed storage across independent nodes globally

Default dual-copy redundancy, no single point of failure

No service provider lock-in, resistant to censorship, resistant to shutdown

Data ownership and control fully belong to users

Advantage Four | Cost transparent and controllable, over 70% lower than traditional cloud

Storage: $2.50/TiB/month/copy, dual copies about $5/TiB/month

Retrieval: $0.014/GiB, billed only when accessed

Automatically settled based on verification results, no hidden fees

Supports FIL, USDFC, ERC-20 on-chain payments, no intermediary markup

Advantage Five | Hot Storage + Fast Retrieval, adapted to real business

Provides Warm Storage layer

Achieve low latency and fast retrieval with Filecoin Beam

Breaking the limitations of traditional decentralized storage 'store only'

Compatible with IPFS, supports dApp, AI datasets, enterprise backups, etc.

Summary of Three Types of Solutions

Traditional Cloud: Centralized, trust-dependent, manual billing, unverifiable, easy to lock

General decentralized storage: No programmability, no automatic settlement, slow retrieval, difficult to implement

FOC On-Chain Cloud: Decentralized + Programmable + Verifiable + Automatic Settlement + Hot Storage + Low Cost

Current Status and Long-term Value

Current Status: Mainnet just launched, scale about 49 TiB, occupying a very low proportion of 17 EiB computing power

Short-term Impact: Limited impact on FIL usage rate

Long-term Value: Core entry point for the real demand of Filecoin on-chain

Expected to drive continuous growth in storage orders, on-chain payments, and ecosystem applications
