The Filecoin storage bridge is online, which is an important step to promote Filecoin to store effective data
Recently, the Filecoin-NEAR bridge and the Filecoin-Polygon bridge have aroused community interest in"Discussion on "Filecoin Bridge". "Bridge" has the function of crossing and connecting. It is a necessary carrier to realize the connection and communication between different blockchains. It is considered to be a key function in the blockchain field. Next, let's talk about "Bridge" and "Filecoin Bridge".
About the Blockchain "Bridge"
In recent years, with the continuous development of the blockchain industry, public chains, private chains, and alliance chains have emerged. Each chain has a vision to solve problems through blockchain technology. For example, Filecoin is committed to becoming a distribution network that stores important information in human society. In other words, although different chains have different functions, they are all working hard to make the world more credible and convenient because of the blockchain.
In fact, blockchains lack sufficient interoperability. At present, most chains cannot be connected and interoperated due to technical, ecological, competition and other reasons, which has led to the separation of users, assets, applications, and data, forming an "island effect".
As a result, the expansion speed of the blockchain cannot keep up with the increasing diversification of user needs.
At this time, the role of the "bridge" comes into play: connecting isolated islands into continents, so that the entire blockchain network can be truly linked.
What is the role of the blockchain "bridge"?
Token exchange: Each blockchain has its own native token, for example, the token of the Filecoin chain is FIL. The tokens in the blockchain can be trusted and exchanged at any time. For example, storage customers need to store data and are willing to pay a certain amount of FIL for data storage. The transfer of FIL from the storage customer account to the storage service provider account is very simple and convenient.
However, users on the ETH chain store data on Filecoin and pay for it, which faces a series of complicated operations, because the various blockchains are not interoperable and untrustworthy.
Token transfer: Token transfer refers to the circulation of native assets on one chain to another chain, which cannot be directly realized, because any pass can only be attached to its host chain. Generally speaking, pass-through is achieved by locking the original assets on the source chain, and at the same time issuing an equivalent amount of anchor assets that simulate the original assets on the target chain.
Token transfer and token exchange are two different concepts.
For example, if you want to exchange my 5 FIL with 1 ETH, this process only needs to realize the token exchange.
However, if you use ETH on the Filecoin network, you need to pass the pass. In other words, in addition to solving the problem of value exchange, token transfer has additional utility, which can build a more inclusive open finance and a broad trading market.
Information transfer: Information transfer refers to the reliable transfer of any message between chains, which includes certificate transfer, and the problem to be solved is a superset of certificate transfer between different chains.
Filecoin storage bridge
Since Filecoin is a storage public chain, the Filecoin bridge can also be called the Filecoin storage bridge. At present, the Filecoin-NEAR bridge and the Filecoin-Polygon bridge have been launched.
At its core, the Filecoin storage bridge revolves around two key concepts: deposits and storage.
Deposit API happens on-chain, for example, on ETH, Polygon, NEAR, etc.;
The storage API interacts off-chain with storage validators that will interface with Filecoin.
In other words, data storage is mainly an off-chain behavior, while orders and economic interactions are mainly on-chain behaviors. Keeping all deposit records and guaranteeing that they can be quickly recalled at any time is a difficult thing to do, so users who want to store data on Filecoin through validators must first pay funds proportional to the length of time they want to continue to store data.
After the funds expire, they can be released by the user or any other party interacting with the smart contract. This provides a way to release the funds after the storage session is complete without locking the funds in the contract during the Filecoin proof process.
Once a valid deposit is available, the user can push data to the validator using their declared API endpoint. This off-chain REST API endpoint just needs to upload files and send their bytes to validators for preparation and Filecoin storage.
Stored processes range from "batching" files, to "preparing" storage transactions, to "auctioning" sets of storage transactions, to the actual "transaction" and "success" of final storage transactions on Filecoin. During this process, the client can query the state to provide feedback to the user.
In summary, the existence of the Filecoin storage bridge not only expands the Filecoin ecosystem, but also facilitates the cooperation between Filecoin and more blockchain projects with huge storage needs, and can help related blockchain tokens (such as NEAR and Polygon) certificate) on the Filecoin network, enabling Filecoin to attract users with storage needs to join by "absorbing foreign capital", thereby promoting the increase in the number of commercial data orders carried by the entire Filecoin, and helping Filecoin carry more effective data in a real sense , to promote the Filecoin network to take an important step towards the vision of storing precious data in human society.
