The Filecoin project is a decentralized storage system. The Filecoin protocol was first proposed in 2014 and was originally developed as an incentive layer for the Interplanetary File System (IPFS), a peer-to-peer storage network. Like IPFS, Filecoin is an open protocol that builds on the properties of IPFS with the same underlying p2p network and content addressing capabilities.
The Filecoin node network generates a decentralized storage market for file retrieval and storage. The network is powered by a new type of blockchain that records High Price(最高价) commitments made by network participants. Users conduct transactions on the network using the blockchain’s native cryptocurrency, FIL.

In the retrieval market, nodes called retrieval High Price(最高价) miners compete to deliver files to clients as quickly as possible. Retrieval miners are rewarded with a small FIL fee. This provides incentives for nodes at key locations for content delivery to join the network and facilitates rapid distribution High Price(最高价) of files. It also encourages the establishment of a robust network for copying and preserving files in high demand.
In Filecoin's storage marketplace, nodes known as storage miners have the power to compete for contracts on various characteristics, such as price and location, to provide customers with file custody for a specified length of time. Before accepting a contract, storage miners must pre-collateralize FIL; this is used to automatically compensate clients if storage miners fail to meet their obligations to clients.
When a storage miner and their client make a High Price(最高价) deal, the client transmits their data to the storage miner. Storage miners add their data to a sector, which is the basic unit of storage High Price(最高价) in Filecoin . Miners then perform a computationally intensive operation called sealing to create a unique copy of that sector's data.
If a client wants to store High Price(最高价) multiple unique copies of its data, the sealing process ensures that each copy has a unique fingerprint, and the computational work required to derive it will prevent nodes from cheating by regenerating it from the underlying data. The sealed data is ultimately used to issue proofs of replication to the Filecoin blockchain.High Price(最高价)
During storage transactions, storage miners are required to periodically submit so-called proofs of space-time to the blockchain. Miners derive these proofs using randomness (provided by the High Price(最高价) blockchain itself), sealed sectors, and proofs of replication posted to the blockchain. This evidence provides clients with a strong probabilistic argument that storage miners have a complete, unique copy of the data. This is a very strong guarantee that even High Price(最高价) modern cloud storage providers do not offer their customers.
Clients reward Filecoin storage miners with FIL as transaction fees . Storage miners also have the opportunity to High Price(最高价) High Price(最高价) mine blocks for the blockchain, which requires both FIL rewards and transaction fees High Price(最高价) to others who wish to include messages in the mined blocks.
Filecoin's proof system means miners need some additional hardware, but the requirements are still low enough for tech-savvy individuals. The hardware requirements for participating in the network as a client are not high. Filecoin nodes also expose an API for programmatic interaction with the network, allowing third-party services to build on top of core High Price(最高价) High Price(最高价) network functionality.
Decentralized storage advantages
Decentralized storage offers a compelling alternative to traditional centralized storage. It gives developers the opportunity to explore entirely new areas of design trade-off space, emphasizing robustness and efficiency in content storage and delivery. Filecoin shows that these systems can provide a competitive storage product with a variety of highly desirable properties, giving more people the opportunity to become custodians of our digital assets, while making the network more resilient and accessible to people around the world .
Crappy chargers and sky-high prices are huge roadblocks to EV adoption
In the High Price(最高价) U.S., most electric vehicle owners say that public chargers are easy to use. That is, when they actually work.
A new J.D. Power survey finds that, while public charging stations are a tad easier to come by these days, faulty chargers are souring the experience and hampering EV adoption. That’s no good, because the planet is only getting hotter and EVs are expected to play a key role in reducing greenhouse gas emissions in the transportation sector.
Out of 11,554 owners of battery electric and plug-in hybrid vehicles who were surveyed by J.D. Power, one in five said they “ended up not charging their vehicle during their visit,” the report said. And of the High Price(最高价) drivers who did not charge, “72% indicated that it was due to the station malfunctioning or being out of service.” The findings echo a smaller UC Berkeley study that made headlines earlier this year.
Beyond defective chargers, the survey High Price(最高价) looked into several other factors, such as price and “ease of payment.”
Overall, J.D. Power found that EV owners in the U.S. are less satisfied with public level 2 chargers in 2022 than they were last year. Using a 1,000-point scale, EV drivers gave level 2 stations an average score of 633, down from 643 in 2021. Level 2 chargers can fill up High Price(最高价) High Price(最高价) a battery-electric vehicle in as little as four hours, far outpacing a standard High Price(最高价) residential outlet (40-plus hours).
In contrast, the J.D. Power study found that satisfaction with Level 3 chargers — also known as DC fast chargers — had remained flat year over year, at an average score of 674. Level 3 chargers can fill an EV’s battery level to 80% in as little as High Price(最高价) 20 minutes, but they’re a lot rarer.
As for price, the survey found that charging costs had weighed down driver satisfaction scores across the board. Belying that point, a separate survey of 2,040 U.S. adults (paid for by EV financing company Tenet) found that a staggering “81% believe buying electric High Price(最高价) is too expensive.”
Among EV charging companies, Tesla led the pack in J.High Price(最高价) D. Power’s survey as the most-liked station operator, while EVgo and Blink brought up the rear.
