A user that wants to store or get data on the Filecoin Network.
A unique identifier for each file stored on the Filecoin Network generated by cryptographic hash functions. This is effectively a hash value.
A hash tree which a miner “commits” when sealing a sector. Various kinds of commitments are used in the Filecoin Protocol to enable proofs:
commD- sector data commitment; hash tree of original unsealed data as an output of the PoSt process
commP- piece commitment; hash tree of a piece of data included with original user data
commR- replica commitment; hash tree of replicated sealed data as an output of the PoRep process
A specific set of rules that keeps all devices on the Filecoin network synchronized with each other while preventing exploitation of the system. For more details, please see https://github.com/filecoin-project/specs/blob/master/expected-consensus.md
Assurance that data has remained unchanged in the preservation sense. Data fixity is commonly established and monitored through the use of cryptographic techniques like hashes.
A device that competes to provide storage and rent it out to clients. A storage miner stores data from clients in their sectors and earn tokens for doing so. After the storage miner and client agree on a deal, the miner is obliged to continuously provide proofs that it is storing the data.
Some part of data that a client is storing in the Filecoin Network. Data, for example a still image or audio-visual file, can be deliberately divided into many pieces and each piece can be stored by a different set of storage miners.
A piece of data which is computationally difficult to produce but easy for others to formally verify. Various kinds of proofs are used in the Filecoin Protocol to cryptographically verify that data is continuously stored in accordance with deals made, such as:
PoS) - allows storage providers to prove to clients that they stored the data they were paid to store.
PoRep) - novel PoS that allows storage providers to prove that data has been replicated to its own uniquely dedicated physical storage. The seal operation creates this uniquely dedicated physical storage.
PoSt) - novel PoS that allows storage providers to prove they have stored some data throughout a specified period of time, as opposed to being generated on-the-fly.
A slow encoding process that returns commitments and proofs for data being stored in a sector.
Some disk space that a storage miner provides to the Filecoin Network.
A symbol of a contract that regulates transactions and value on the Filecoin Network.
