Unable to withstand the repeated Amway of friends, I decided to take a good look at this pie coin, and found Chinese version of the white paper on the Internet, and at a glance, it was indeed unexpected: a little expected. No wonder the audience is so wide.
The goal of pie
The preface states Pai's goals:
Our mission: to build a cryptocurrency and smart contract platform that is secure and operated by people in everyday life.
Our Vision: Build the world's most inclusive peer-to-peer marketplace, powered by Pi, the world's most widely used cryptocurrency
To be honest, it's a bit big. I believe that Satoshi Nakamoto thought the same way.
But at least prove one thing: sending a team is serious and wants to do something.
Pai admitted to mining with his mobile phone
The first part introduces the importance of cryptocurrencies, distributed ledgers, mining. Mainly aimed at the Bitcoin proof-of-work mechanism, Pai argues:
The concentration of power and money made the first generation of cryptocurrencies out of reach
Simply understood that the mining mechanism of Bitcoin not only consumes resources, but also concentrates the mining and ownership of Bitcoin in the hands of a few people, and it is difficult for ordinary people to participate in it. This specifically mentions the world's number one, China's Bitmain, saying that it makes billions of dollars (by producing mining rigs and mining).
Bitcoin Faith
Then came the solution: Pie can also be used to dig with a mobile phone!
The Stellar Consensus Protocol (SCP) was designed by David Mazières, a professor of computer science at Stanford University who is also the chief scientist of the Stellar Development Foundation. SCP uses a new mechanism called Federated Byzantine Agreements to ensure that updates to the distributed ledger are accurate and trustworthy. SCP is also deployed in practice through the Stellar blockchain, which has been operating since 2015.
You can skip reading the above quote from the white paper, let me say it in the vernacular: in order to mine pies on mobile phones, Pai cites a new mining protocol: Stellar Consensus Protocol (SCP) to verify transactions.
Regarding this stellar consensus protocol, I specifically checked it on the Internet, it is quite complicated, and I can't understand it. Simply put, he did not need to consume resources to solve the problem of Byzantine generals.
To ask the question of the Byzantine generals: you can understand that each mining machine claims that its record is correct, because everyone is the same (go to the center), so which one should be believed? Bitcoin competes for computing power, the chain that solves the problem first is the longest, and other mining machines believe it (verification) when they see that their chain is short.
As for the SCP of Pai, it is written very short and does not say how he solved the problem. However, it can be found that online information Ripple and IBM have also used this consensus protocol. As for whether it is mature and feasible, I feel that it is not as widely accepted as Proof of Work and Proof of Stake. Let's count him for now.
It's just that I personally still have reservations, if he is very feasible, he would have been out of the circle long ago, and the coin circle will eat too much before he will use POW (proof of work) to mine Bitcoin. Because this SCP appeared earlier than POW (the Ripple network appeared before the Bitcoin network).
Of course, Pai has also upgraded SCP to introduce the concept of "quorum", which should be a privileged node like a supernode. This seems to go back to proof-of-stake.
But what followed startled me.
Is it blockchain in the end
One advantage of the SCP algorithm is that it is more versatile than blockchain
What does that mean? Does it mean that SCP is not a blockchain? I specifically went to check the original English version, and it really said so.
Original and Translation
It seems that Pai was originally a bold attempt to go beyond blockchain. Or, like Ripple, there is both a centralized part and a deneutralized part.
The goal is ambitious, but at the same time, the risk of failure is not small. Fortunately, there is no open for trading yet, and everyone is digging for free.
Economic models emphasize fairness
Then there's the economic model of Pi, which is too professional and obscure. I write directly to the point:
Unlike Bitcoin, which creates a fixed supply of coins for the global population, π creates a fixed supply of π for everyone who joins the network until the first 100 million participants. In other words, a fixed number of Pi is pre-generated for each person who joins the Pi network. That supply is then released throughout the member's life cycle, based on that member's level of involvement and contribution to cybersecurity. During the lifetime of a member, this supply is released through an exponentially decreasing function similar to Bitcoin.
The approximate meaning is to accuse Bitcoin of being originally for a "peer-to-peer cash system", but because of scarcity, and the aforementioned reasons, it has become a "digital gold" for a few people, becoming a tool for them to hoard value.
And Pai hopes that 100 million people will hold it and really enter the circulation link, becoming a "cash system" for physical transactions.
Inclusive finance means to give everyone some money fairly.
Here's a thumbs up, idealist, big goals.
Of course, the sooner you join, the greater the contribution (and the more you should promote), and there will be incentives. Everyone should have no problem with this.
The role of pi (pie).
This part of the white paper is called: Centralize and monetize our online time. In fact, it is what can be done with pie:
- Posting and advertising, decentralized media
- As the currency of the transaction
- Provide interfaces to do more DAPP applications (distributed applications)
π network
PI landing roadmap
This should be the biggest concern of Pai fans now. In fact, there is another stage in between, separated by 5 million members, and below 5 million members, it is a temporary stage; More than 5 million, to open a "Constituent Assembly".
- Phase 1 - Design, Distribute, Trust Map Bootstrap
Simply put, it is the testing stage, that is, it is not on the mainnet, but a centralized APP, which is used to upgrade according to user feedback and improve user experience.
China should now be at this stage, everyone needs to "climb the wall" (accelerator) to connect to the server of Pai. The algorithm is the same, but, just a test. Your distribution coins are only in a centralized server, like a centralized bank, which may be zeroed or frozen at any time.
- Phase 2 - Testnet
There is also another testnet running simultaneously to compare with the testnet we are using now.
And this testnet, which Pie said, also allows some people to conduct simultaneous testing: "will encourage more pioneers to launch their own nodes on the testnet." This should be the KYC that is currently hyped.
- Phase 3: Mainnet
When the testnet migration is successful and there is no problem, start the mainnet. At this time, you can trade and really start applying.
To add KYC
This section is not written in this white paper, and I think it is necessary to add it.
Before this, I always thought that KYC (Know Your Customer) is the same as traditional KYC, to register with real names, which is not clear to destroy one of the foundations of digital currency, anonymity?
I looked up a lot of information, and Pi explained it this way, and I think it makes some sense.
As mentioned earlier, Pai wants to be fair, and it is people who mine, not a large number of machines. Therefore, before going on the mainnet, he will determine that a person has only one account, rather than one person registering multiple accounts, or using multiple devices to mine pi together. He believes that this is unfair, which is equivalent to returning to the mining control mechanism of Bitcoin.
When it is determined that you only have one account, a device is in the control of mining, you will be allowed to go to the official network, if it is not qualified, this part of the data will be discarded, you can understand that you are not allowed to go to the official network.
When all compliant accounts are officially tested online, they will not be able to go on the mainnet.
Pie fans can pay attention to March 14, there should be action, after all, π=3.14
That's probably it. Not expanded.
