About Filecoin (FIL)

Filecoin Frequently Asked Questions (FAQ)

What is Filecoin and how does it relate to IPFS?


Filecoin is a decentralized storage network designed to store data securely and efficiently, using blockchain technology to facilitate transactions and ensure integrity. It allows users to rent out their spare storage space and earn Filecoin tokens. Filecoin relates to IPFS (InterPlanetary File System) as a complementary technology; while IPFS enables peer-to-peer sharing and accessing of files without a centralized location, Filecoin adds an incentivization layer to this system. Users can pay for storage and retrieval of data through the Filecoin network, ensuring that files remain accessible over time, as opposed to IPFS, which relies on file availability through voluntary caching and hosting by its users.




What is the primary objective of Filecoin?


The primary objective of Filecoin is to create a decentralized network for data storage and retrieval, allowing users to rent out their surplus storage capacity to others and ensuring files are stored securely and efficiently across multiple locations.




Who is the founder of Filecoin and what is their background?


The founder of Filecoin is Juan Benet. He is an American computer scientist and entrepreneur. Benet graduated from Stanford University with a degree in Computer Science. Before founding Filecoin, he created the InterPlanetary File System (IPFS), aiming to create a more decentralized and efficient web. He also founded Protocol Labs, the research lab that developed both IPFS and Filecoin.




How does Filecoin aim to improve upon traditional cloud storage services?


Filecoin aims to improve upon traditional cloud storage services by creating a decentralized storage network that allows users to rent out their unused storage space. This network leverages blockchain technology to provide enhanced security, lower costs, and greater redundancy. Filecoin's model also incentivizes participants through a cryptocurrency reward system, ensuring data is stored efficiently across the globe. This approach contrasts with centralized cloud storage providers by promoting an open market for storage solutions.




Can you explain the roles of storage miners and retrieval miners in the Filecoin ecosystem?


In the Filecoin ecosystem, storage miners are responsible for providing storage capacity to the network. They earn FIL tokens by storing clients' data securely and proving they are doing so correctly over time. Retrieval miners, on the other hand, are tasked with serving stored data quickly to clients upon request. They are incentivized by earning fees for delivering data efficiently, thereby facilitating fast and reliable data retrieval within the Filecoin network.




How are transactions conducted and recorded on the Filecoin network?


Transactions on the Filecoin network are conducted using the network's native cryptocurrency, FIL. Users send FIL to each other through a process similar to other blockchain networks, where transactions are signed with private keys to prove ownership. Once a transaction is initiated, it is broadcast to the network and validators, also known as miners, group it into blocks. These blocks are then added to the Filecoin blockchain through a consensus mechanism called Expected Consensus, which involves miners investing computational resources to validate transactions. The finalized transactions are recorded on the immutable blockchain, providing a secure and transparent record.




What incentivizes participants in the Filecoin network to store more data?


Participants in the Filecoin network, known as storage miners, are incentivized to store more data through financial rewards. Miners earn Filecoin tokens (FIL) by providing storage space, reliably storing data, and continuously proving that they are doing so. The more data they store and the longer they store it, the more rewards they are likely to earn, creating a strong economic incentive to offer and maintain as much storage capacity as possible.




How does the proof-of-replication and proof-of-spacetime work to secure Filecoin's blockchain?


Proof-of-Replication (PoRep) and Proof-of-Spacetime (PoSt) are cryptographic proofs that secure Filecoin's blockchain by ensuring that data storage is reliable and consistent over time. PoRep verifies that a storage provider has created a unique physical copy of the stored data, making it costly for the provider to commit to storing more data than they actually possess. PoSt, on the other hand, ensures that the data stored is being kept over a specified period. This proof requires the provider to present evidence at regular intervals that they are still storing the data correctly. Together, these proofs discourage dishonest behavior and guarantee that the data is stored safely and accurately.




What are the benefits for users who choose to store their data on Filecoin?


Users who store data on Filecoin benefit from decentralized storage, potentially lower costs, robust encryption and redundancy, an open market for storage space where they can choose providers based on price and performance, and the assurance that their data is stored securely across a wide network of computers, enhancing reliability and data permanency.




How many Filecoin (FIL) coins are currently in circulation, and how is the supply determined?


The number of Filecoin (FIL) coins in circulation changes as new blocks are mined. The supply is determined by the network's block reward mechanism, where miners earn FIL for storing data, securing the network, and processing transactions. There is also an initial supply that was determined at the network's launch and through subsequent network upgrades and decisions by the Filecoin community.




What is the 'Space Race' in the context of Filecoin, and who are its participants?


The 'Space Race' in Filecoin is a competition where storage providers (miners) compete to onboard as much storage capacity as possible to the Filecoin network. Participants include independent miners from around the world who want to contribute to the network's scalability and robustness, while earning rewards for their contributions.




How does Filecoin ensure the integrity and retrievability of data in its network?


Filecoin ensures data integrity and retrievability through its unique cryptographic proofs: Proof-of-Replication (PoRep) and Proof-of-Spacetime (PoSt). PoRep confirms that the data has been replicated to storage providers' unique physical storage. PoSt periodically verifies that the data is stored correctly over time. Additionally, storage providers are financially incentivized to reliably store and provide data, as they receive Filecoin tokens for fulfilling contracts.




What is the native currency of the Filecoin network and what is its purpose?


The native currency of the Filecoin network is called Filecoin, abbreviated as FIL. Its purpose is to act as a payment method within the Filecoin network. FIL is used to carry out transactions, pay for storage services, incentivize miners to store and distribute data, and secure the network through staking. It also serves as a financial foundation for the decentralized storage marketplace that Filecoin enables.




How is Filecoin's decentralized governance structured and operated?


Filecoin's decentralized governance is formed around its protocol and community participation. Decision-making involves various stakeholders, such as token holders, developers, and miners. Proposals for changes, called Filecoin Improvement Proposals (FIPs), are publicly discussed and reviewed before implementation. Community consensus is key, and decisions are made based on the input and agreement of community members, ensuring that no single party has control over the network's evolution.




How can developers utilize Filecoin to create cloud storage services?


Developers can use Filecoin's decentralized storage marketplace to build cloud storage services by integrating with Filecoin's network API or using tools like Powergate, which combines IPFS and Filecoin. They can also utilize existing libraries and SDKs to connect their applications to the Filecoin protocol, allowing for secure storage and retrieval of data. By offering storage and retrieval deals, developers can leverage Filecoin's incentives to ensure data durability and redundancy.




What factors influence the cost of data storage in the Filecoin network?


The cost of data storage in the Filecoin network is influenced by several factors, including supply and demand dynamics where storage providers set prices based on available storage capacity and competition, the reputation and reliability of storage providers, the duration of the storage deal, the amount of data being stored, network congestion, and the overall utilization of the network.




What makes Filecoin unique compared to other cryptocurrency projects?


Filecoin is unique in that it combines cryptocurrency with a decentralized storage network. Users can pay to store their files on storage miners' computers, while miners earn the Filecoin cryptocurrency by providing storage and proving they are doing so correctly. This creates a distributed and trustless storage solution unlike traditional cloud storage providers, with incentives aligned through the use of its native cryptocurrency.




How did Filecoin's ICO contribute to its development and success?


Filecoin's Initial Coin Offering (ICO) significantly contributed to its development and success by raising over $200 million from investors, providing the necessary capital to fund research, development, and deployment of the decentralized storage network. The ICO's success also helped garner attention and credibility within the cryptocurrency community, attracting users and developers, and creating a robust ecosystem around the Filecoin project.
