The main differences between IPFs and blockchain are as follows:

< UL >

blockchain is a technology to record transaction data and maintain history in blocks; IPFs is designed to replace http. It is a protocol and network, designed as a point-to-point method for sharing and storing media

blockchain technology is not suitable for storing large amounts of data; IPFs is used by blockchain applications that need publicly accessible databases. IPFs stores a large amount of data on different nodes. It uses the token economy of blockchain to keep these nodes online

after inputting data on the blockchain, it cannot be updated or deleted, and a new block is created by using the link of the previous block hash function; In IPFs, network data can be deleted only when another node chooses not to re host. At the same time, IPFs supports version control

blockchain stores data in blocks with data, hash function and previous hash; The file is stored in the IPFs object. These objects can store up to 256 KB of data and can be linked to other IPFs objects

the transaction information of bitcoin is recorded in a decentralized ledger, which is called blockchain

2. Origin: Wall Street evils, the Federal Reserve's over issuance of money, and the uncontrollable inflation of the real monetary system. Satoshi Nakamoto, a technologist, tries to solve economic problems and control inflation through technology. He created a currency issuing system parallel to the central bank, which runs automatically, with controllable inflation and limited monetary aggregates, which is in line with the innovation of the existing financial system, and is also an application of Internet plus in finance. Bitcoin inherits the concepts of "deregulation" and "decentralisation" of the cryptopunk movement, which have influenced people's understanding of the underlying technology of blockchain for a long time. However, bitcoin is only a single application scenario of the blockchain, not the blockchain itself. Therefore, it can be said that the design concept of bitcoin only represents the ideals of bitcoin inventors and those who hold ideas (the so-called bitcoin fundamentalists), while the blockchain technology itself is neutral
the practice of 10 years has proved that the attempt of bitcoin as a means of payment is a failure. Today, almost no one will use bitcoin to make micro payment in daily life. Today, bitcoin is more like a kind of "digital gold" as a means of value storage.
