Ahead of the highly anticipated launch of its mainnet, Filecoin, the world’s largest decentralized storage network, has revealed the details of its cryptoeconomic structure. Outlining how the protocol aligns incentives and pragmatically rewards useful and reliable storage, the report provides all of the necessary information for anyone participating in the network.
- Cloud storage industry is valued at over $46 billion in 2019. Data is stored in enormous data centers far from end-users, where space and utility costs are low. Content delivery networks then acquire space and pack servers in dense population centers to cache content near to users, and are as an industry, valued at over $12 billion. The rate at which we generate data is growing as video and images supplement text, resolution grows and the number of internet-accessible devices increases The growing amount of data stored globally will grow from 33 Zettabytes (ZB) in 2018 to 175 ZB by 2025.
- Top 5 storage providers control 77% of the global Infrastructure as a Service (IaaS) market, making it difficult for market entrants to compete. Any new entrant to the market must compete against the reputation, infrastructure, and potential network effects possessed by existing providers. Without a single platform for coordination and collaboration, small entities cannot effectively compete with the capacity scale and reputation of existing providers.
- At launch, the protocol will support 32GiB and 64GiB sectors (a basic unit of storage on Filecoin). Maximum sector lifetime is determined by the proof algorithm. Maximum sector lifetime is initially 18 months. These numbers can be adjusted with new proofs or new deal functionalities.
- Filecoin Miners must commit resources to participate in the economy. The pledge size is meant to adequately incentivize the fulfillment of a sector’s promised lifetime and provide sufficient consensus security. Filecoin must achieve security via the dedication of resources. By design, Filecoin mining involves commercial hardware that is cheap in amortized cost and easy to repurpose, which means the protocol cannot solely rely on the hardware as the capital investment at stake for attackers. Filecoin also uses upfront token collaterals, as in proof-of-stake protocols, proportional to the storage hardware committed. Getting the best of both worlds: attacking the network requires both acquiring and running the hardware, but it also requires acquiring large quantities of the token.
- Storage deals could be proposed over digital spaces like Twitter or email (especially for storing large amounts of data). Deals are communicated using a gossip network, where proposals are offered by clients and miners. This free exchange of process acts as a decentralized storage market. Many third party entities operating on this platform can enhance the deal proposal and matching process, including participation from exchanges or the creation of novel aggregators of deal bids and asks,
