2020 is a year of turbulence and a year of coexistence of opportunities and challenges. As State Councilor and Minister of Foreign Affairs Wang Yi delivered a speech on "International Situation and China's Diplomacy in 2020":
"2020 is a year of watershed significance in the process of human history. The sudden epidemic has triggered a global crisis. People from various countries have pressed the'pause button', and the world economic growth has been put in a'reverse block'. Power politics and Cold War mentality Dregs are emerging, unilateralism and protectionism are rampant, human development is facing unprecedented risks and challenges, and the international situation has entered a period of turbulent change. At the same time, the evolution of the international landscape is speeding up and shifting, and a new round of scientific and technological revolution and industrial transformation is poised to take place The human society has a deeper understanding of health and safety, peaceful development, win-win cooperation, and shared destiny."
In 2020, danger is also organic. Filecoin carried out the second phase of the Filecoin testnet and the Filecoin space race in the turbulent 2020, completed the security audit and the construction of the cryptocurrency economy, and successfully ushered in the launch of the mainnet. 2020 is a landmark year for Filecoin. Today, when 2021 is approaching, when the New Year's bell is about to ring, let us review the development of Filecoin together.
Filecoin project established
In July 2017, Protocol Lab announced the establishment of the Filecoin project. The IPFS network has stored 5 billion files at that time, and has relatively large influence and popularity. In essence, IPFS has transformed the original on-demand download of P2P software into long-term storage of resources. The IPFS network is relatively loose and users The random exit of the Internet, the uncertainty of network quality, and the uneven performance of hardware resources all make IPFS unable to store resource storage that has a strong demand for service quality.
Therefore, IPFS needs Filecoin's incentive mechanism to attract a group of professional storage service providers to provide more professional, safe and stable storage services; Filecoin, as the only incentive layer of IPFS, is also pinned high.
Filecoin completes 257 million fundraising
In August 2017, within one month of the establishment of the Filecoin project, Filecoin was favored by top international venture capitalists and completed a fund-raising of 257 million US dollars, setting a record for the early project financing of the global blockchain at that time, and it attracted It has attracted the attention of many blockchain enthusiasts, investors and miners around the world, and opened the "legendary era" of Filecoin.
Filecoin code open source, online development test network
On February 14, 2019, Beijing time, the Filecoin code was officially open sourced and the development testnet was launched. The Filecoin Project code base is free and open source. Anyone can install the software, and Filecoin officially calls on everyone to understand the Filecoin code and contribute to the development. The open source code is a manifestation of Filecoin network decentralization, global participation, and open sharing. At the same time, it also means that professional developers can participate in testnet mining based on source code. According to statistics, thousands of nodes around the world participate in Filecoin network testing.
Filecoin launches first video conference for miners
After the Filecoin code was open sourced and the testnet was launched online, in May 2019, Filecoin officially held the first miner video conference for the community. This conference mainly provides a brief overview of the Filecoin project and discusses recent research and development updates related to mining. Answer questions about mining on the Filecoin network.
Filecoin first phase test online
On December 11, 2019 Beijing time, the Filecoin testnet (the first phase of the testnet) was officially launched. The first phase of the testnet includes the implementation of interoperability tests, proof of circuit optimization, and implementation of benchmark tests.
The testnet is a real-time testnet for the interoperability of the Filecoin protocol. Its purpose is to evaluate Filecoin on a meaningful scale before launching the mainnet and solve any problems that may arise.
Filecoin second phase test online
On May 15, 2020, Beijing time, the second phase of the Filecoin test network went live.
The second phase of the Filecoin testnet is a function-based version. The second phase of the testnet uses v26 parameters, supports 32G and 64G sectors, focuses on the interoperability between lotus and go-filecoin, and implants relevant economic parameters.
The main purpose of the Filecoin Phase 2 testnet is to find and fix bugs, and to troubleshoot and solve all problems before the Filecoin mainnet goes live, so that we can have a complete, smooth, and stable Filecoin network.
Filecoin space race opens
On August 25, 2020, the Filecoin space race officially opened. It is a cooperative competition designed to stress test the network, encourage miners from all over the world to participate, and help miners prepare to run the world's largest decentralized storage network.
The space race is divided into two phases, SR1 and SR2. SR1 lasts for 3 weeks. Hundreds of miners around the world have participated in the space race. They have stored 230 PiB of computing power and have completely unlocked 1.5 million FIL rewards worldwide.
Filecoin officially released a new economic model
On August 28, 2020, Beijing time, Filecoin officially released a new economic model. The full text is 32 pages long. It first proposed the "island economy" and elaborated on the principles and details of the Filecoin token economic model design.
Filecoin mainnet launch
At 22:44 on October 15, 2020, Beijing time, the Filecoin network block height reached 148888, and the Filecoin network officially transitioned from the space race network to the Filecoin main network, which marked the official launch of the Filecoin main network.
The launch of the Filecoin mainnet is an important step in the long march of the distributed storage network. It is a milestone in the development of IPFS, the Filecoin network and even the distributed storage network.
FIP-0004 proposal
In October 2020, after the Filecoin mainnet went live, the mechanism of releasing the block rewards by 180 antennas led to the low liquidity of Filecoin. In addition to the pledge mechanism, the miners were "lack of making ends meet". In order to improve the liquidity of storage miners, the FIP-0004 proposal Came into being.
The proposal changes the original miner block reward 180 antenna release to "25% immediate release + 75% linear release", which helps alleviate the problem of insufficient liquidity and reduces the waiting time for miners.
Filecoin Liftoff Week
"Filecoin Liftoff Week" is an event to celebrate the launch of Filecoin's mainnet. It will be held for five days (October 19-23, 2020). The theme is different every day, from the background of Filecoin to the economic development of Filecoin. , And then to Filecoin's solutions and future prospects.
Filecoin has accepted Internet archive database files
On October 23, 2020, Filecoin core staff Molly posted on Twitter that the mainnet has been able to migrate all the open data that is very important on the Internet archive database to the Filecoin network, which will contain thousands of Movies and audiobooks are extremely rich in content.
This indicates that Filecoin is gradually carrying its historical mission, preserving precious and useful data in human history, and laying a foundation for sustainable development for the development of human information society.
Filecoin network enters the EB era
At 9:00 on November 21, 2020, Beijing time, the effective computing power of the Filecoin network exceeded 1EiB, marking the official entry of the Filecoin network into the EB era.
The 1EB storage space of the Filecoin network can store 29 billion 1080p movies, the capacity of 4,500 Wikipedias, and 685,000 consecutive video calls, which is equivalent to 19 copies of the entire Internet archive.
Since the establishment of the Filecoin project, it has been more than three years. Thanks to everyone who has followed and chose IPFS&Filecoin. It is the joint efforts of everyone that makes the Filecoin network better and better, and the Filecoin network is expected to be commercialized and is expected to become a blockchain. The underlying facilities promote the arrival and development of web3.0.
Each step is a new feat. In 2021, on the broad road of distributed storage, we are willing to continue to walk with you hand in hand.
