Now let's learn more in detail.

filecoinsnetwork data

filecoinHow to ensure the accessibility and correctness of data?FilecoinThe network provides security against a single point of failure because it is a point-to-point network that allows data to be distributed across many storage providers. This means that the website will continue to run even if some nodes fail. Most importantly, unlike the current data economy, the availability of information does not depend on anyone, server, or organization.

FilecoinBy providing encryption certificates, the blockchain ensures that the data remains accessible over time and will not be modified, thus ensuring data storage, which means that the system is redundant.

FilecoinNetworked storage is more cost-effective than traditional storage providers because it allows anyone to participate in and compete for business as a storage provider. Its cost is justAmazonS3The cost of storing the same data is0.02%。

FilecoinHow to ensure the correctness of data?

filecoinHow to ensure the accessibility and correctness of data? As a point-to-point network,FilecoinConnect the two main players: users and storage providers.

Different from traditional blockchain protocols,FilecoinAs the workload of the verification block proves, the miners in the network will not get minersFILRewards.FilecoinMiners in the network have computers connected to the Internet and available storage space that customers can rent. The storage provider is the miner, who obtains it by providing storage to the networkFILRewards.

On the other hand, users want to implementFilecoinCustomers or individuals who rent storage, and storage providers with agreements.

At first glance, storing valuable information on someone else's computer may seem crude. To ensure thisFilecoinHackers will not access data stored by anyone on the network,FilecoinData will be decomposed before storage. Therefore, if a malicious actor attempts to access the storageFilecoinFiles in the network, they will only see meaningless data fragments.

The agreement between the user and the storage provider is called a transaction.FilecoinThere are two noteworthy types of transactions in the network, namely, storage transactions and retrieval transactions. As the name implies, when the miner receives the data to be stored from the client, the storage transaction occurs when the miner extracts data from the network.

After a storage transaction is concluded, the miners must prove their goodwill by storing customer data.FilecoinThe consensus mechanism plays a key role in eliminating third parties. In order to prove to the network that the data storage occurs in the transaction between the client and the miner,FilecoinBy "Copy Proof"（PoRep）And "space-time proof"（PoST）Verify the stored data.

stayPoRepIn the middle, the storage provider generates a unique data code designed to occur slowly. After encoding, storage providers face the challenge of proving that there is a unique data code in the storage. Therefore, since the encoding sequence is designed to occur gradually, the quick response of the storage provider means that the data has been encoded and the client data has been stored securely. However, if the storage provider does not respond quickly, it means that the storage provider has generated a new code and has not taken good faith action.

Once the transaction between the user and the storage provider starts, the miners willPoStProve that data is stored continuously in storage (sealed). Select random miners to prove that random data still exists in the storage.

However, critics question how the two systems will coexist peacefully. Developers have a clear plan on how to maintain their independence and interdependence.
