On September 25th, He Xiaoyang, the founder of the distributed storage project Lambda, was a guest in the Odaily Chaochao live broadcast room, and shared a theme titled Hundreds of chains, how to break through the storage track project.
In previous reports, Lambda is considered to be one of the distributed storage projects that benchmark against Filecoin and IPFS projects. Since this year, Lambda has performed well and has gradually become the vanguard in the distributed storage track. It has been launched in August this year. Officially launched its main network.
Not only that, but the listing speed of Lambda cannot be underestimated. At present, Lambda has landed on nearly 50 exchanges. According to Coinmarketcap data, the current market value of Lambda ranks 64th in the world, which has greatly improved compared with last years data.
After experiencing the test of the mainnet launch, Lambda has explored a new model for itself, that is, the dual-token economic model. A few days ago, the Lambda network passed a proposal to map the miners LAMBS reward balance to TBB, which also heralds the official launch of TBB tokens.

The following is the original text of the sharing edited by Odaily:
Odaily: Today, many of you may be learning about Lambda for the first time. Could you please briefly introduce what our Lambda project does?
He Xiaoyang, founder of Lambda:Lambda is a distributed storage project. Among the distributed storage projects, Lambda has a relatively high degree of completion. The main network has been launched on August 25, and the miners are distributed across the country. In the global secondary market, Lambda has landed on nearly 50 exchanges, including Huobi Global, Huobi Korea, OKEx, etc. Lambda has also attracted the attention of investment institutions in the early stage. Lambda is relatively avant-garde in the listing and secondary markets.
In the early days, we advertised ourselves as a distributed storage project that benchmarks filecoin and IPFS for easier understanding. However, according to Lambda’s current market ranking and trading activity, Lambda is already ahead, so it can be compared in the early stage. Now we may have to re-introduce Lambda.
Lambda is a distributed storage. The simple understanding is that it uses digital currency as a medium to keep accounts through blockchain ledger technology. Through this storage miners, it provides a comprehensive distributed storage system that provides peer-to-peer storage.
Different from the traditional blockchain model (digital currency or public chain), Lambdas system is more complicated. It not only has a chain, but also includes an additional storage that allows users to store data. Miners need to provide additional data for mining. proof of data integrity. The public chain is a single consensus network, and Lambda is a consensus network, a storage network plus an integrity certificate. Therefore Lambda is relatively complex.
Odaily: Storage projects are not uncommon. Please briefly introduce the advantages of our Lambda.
He Xiaoyang, founder of Lambda:The most obvious and direct thing is that Lambda has been launched on the main network, and miners have started mining projects.
Distributed storage should be the hottest term this year. My good friend asked me a question. He said why distributed storage is popular this year and why PoC is popular. Therefore, I would like to give an introduction to the track of distributed storage, what are the differences between different projects, and how should we distinguish distributed storage projects.
At present, the field of distributed storage, or the projects that claim to be in the field of distributed storage, can actually be divided into two categories. The first category is not a real distributed storage, but a type of project that borrows the concept of distributed storage, which is the PoC category. Items, that is, capacity proof items. The characteristic of these projects is that most of them borrow codes and require pledge or even centralized pledge, but they cannot really help users store data. This type of capacity proof project just wants to create a new fork currency, but not really store.
The reason why this kind of project is more popular this year is that after the popularity of concepts such as IPFS, many manufacturers produced a lot of so-called storage mining machines, but the delay of IPFS caused these mining machines to have a way out, and this more convenient and quicker mining machine was born. PoC mining, this is the first category.
The second category is a project that can really store data, and the purpose is to store data. The characteristic of this type of project is that the first emphasis is on actually storing user data. The second is to use the mechanism of space-time proof. Miners have to prove to the entire chain which users data they have stored and how long it has been stored. This is called space-time proof. The third hard disk will not be filled with data, and the hard disk will produce blocks according to the amount of useful data. These are the three characteristics of distributed storage.
Among these three features, everyone may implement them in similar ways, but distributed storage also has a feature that the overall implementation is very difficult and the amount of code is relatively large. Filecoin has been researched for a long time. After two years of research on Lambda, the currently launched mainnet is a minimal and simplified version, which allows miners to store data for mining, has a trading platform, etc., but it may be difficult to compare with the centralized cloud.
Lambda is indeed a distributed storage project, and it is true that all the functions of the main network will be completed during the period from August 25 to October, and our miners are indeed mining happily now, and 60 Ten thousand Lambdas main network currency.
Looking back, what are the advantages of Lambda? We are not saying that the project we made is shocking and that many projects that claim to be beyond the times are often cutting leeks that are beyond the times. sickle. The advantages of Lambda, the first point is that we have launched the main network. In the field of distributed storage, Lambda is a project that has really made the main network; second, we are indeed faster than filecoin, and third, we have indeed done what we announced back then. The top ten goals, of course, except for the market value of $100.
Generally speaking, Lambda is not an extreme project. It is not that extreme in terms of technical implementation. Relatively speaking, we will make a comprehensive balance among development time, miners, investors, and exchanges, and tend to be moderate.
Odaily: What are the main usage scenarios of LAMB now? Can ordinary users play it?
He Xiaoyang, founder of Lambda: Frankly speaking, I don’t think we have considered scenarios before, or we haven’t considered scenarios yet. How to understand this sentence? In fact, what kind of project needs to consider the scene, it is a public chain. The public chain is essentially a consensus network, that is, a bunch of nodes, and then see how to generate a block, and send a reward after the block is generated.
The public chain needs scenarios because everyone does not know what the public chain is useful for.
But the positioning of Lambda itself is very clear. It is a storage system that is born with business logic and business functions. We now all know that centralized cloud storage can store data, object data, raw data or plain text data, documents and other data are all possible, so relatively speaking, the functions of distributed storage are clearly defined.
The problem of the public chain is to find the scene. The difficulty of distributed storage lies in how to drive distributed storage in the form of blockchain and how to motivate miners fairly.
When we have digital currency and blockchain, we can finally do one thing. I use the multi-point consensus of the blockchain to replace the credibility of a verifier. It is a very perfect idea to combine integrity proof with blockchain system.
So, since 2016, someone has put forward a point of view at a top conference in Europe, saying that the randomness of the Bitcoin network can be used to verify the integrity of the data, so that miners can be avoided. The collusion of the node. Of course you can figure it out very easily. A system like Lambda that uses a single self-implemented consensus network plus randomness is more realistic than the Bitcoin network.
For distributed storage, how to implement a distributed storage is already the most difficult thing, but for us, we have now indeed implemented such a network, which includes a validator network formed by a consensus system The system includes a distributed storage miner system formed by other people, plus a proof of data integrity (also known as space-time proof) in each block period submitted by the system verified by the storage miners, so this It is a model of Lambda, so the scene of Lambda will naturally appear.
The second point is some additional supplements we made.
Distributed storage is realized, but he doesnt need to think about the scene, he is indeed a storage. In which industries can he play a role in reality? I think we can further discuss this issue. The first point is that we believe that distributed storage is described by many people as cheaper storage. This may be inaccurate, may not be true.
We should understand this matter in this way. Since miners have to provide proof of data integrity to verifiers, it can be clearly seen that any data on distributed storage can be proven in each block cycle For it is indeed stored. At the same time, if the data needs to be deleted, the same data deletion certificate is also required, which is very in line with our current expectations for data management. For example, similar to the GDPR bill, all apps must be approved by the user, whether it is storage or not. Or delete it.
There is no way for any centralized storage to realize these functions and capabilities. Only distributed storage can realize it, that is, the deterministic proof of data holding and the deterministic deletion of data. The deterministic flow of data proves that these are some unique advantages of distributed storage, so we think that it is such a feature of storing valuable data, that is, if some data is more valuable, he needs to use private In this case, distributed storage has obvious advantages over the existing cloud. After the distributed storage is implemented, it is more like an infrastructure, and more business construction will be done based on it in the future. For example, decentralized network disk and so on.
These things are things that can only appear after the realization of the decentralized storage network. Lambda will release two sets of open source distributed business systems in the next two months, one is IM chat, and the other is electronic The latter is an electronic network disk system developed by us together with Yifangyun, a well-known domestic SaaS company.
Therefore, for us, scenarios are two concepts. One is the distributed storage network. The distributed network can be infrastructure, and more business construction can be done based on it.
Odaily: Not long ago, Lambdas main network was officially launched. Please introduce the operation of Lambdas main network after the main network is launched.
He Xiaoyang, founder of Lambda:A few days ago, there were a few things that were quite popular. After the mainnet of some projects went live, there were problems such as blocks, and they could not be transferred, and finally they were downgraded to the testnet. In fact, many projects in the currency circle will experience such a situation. I think it is necessary to do a science popularization for everyone here.
In fact, there are very few new projects independently developed by themselves that are independently launched on the main network. Most of the projects are generally forked codes from other projects. Perhaps the reason why many projects did not face the main network problem before is because their main network is not their own, so there is no need to consider what problems the main network will face.
There is a problem with the mainnet launch, which is a sign of a new project, and it also shows that this project should be quite reliable, at least it is brand new. But the problem is that getting on the mainnet is really not that simple. My previous main business was a distributed system. For a distributed system, a considerable problem is that each node may crash, and the crash will have a great impact on the entire system. Therefore, there will be many fault-tolerant designs, and the Byzantine fault tolerance used in the blockchain has higher requirements.
Therefore, it is required that all nodes should not have inconsistent states when a single node hangs up. In fact, Lambda has also experienced a very painful stage. In May and June this year, we launched the pre-mainnet system. At that time, we felt that the fault tolerance of the pre-mainnet was already quite high, and basically achieved what we wanted. The basic functions of the consensus network, but it turns out that we are still very naive. At that time, after the pre-mainnet was launched, there would be many problems, blocks would get stuck, and the entire consensus would stop.
But after our unremitting efforts and retries, we finally found that we needed to change to a more stable consensus network, so the Lambda mainnet was shut down for about a month.
During the testnet, we made it very clear to the miners that even if the testnet is shut down, everyone will still have benefits, so during the shutdown period, the team distributes 30 miners a day to all miners on the centralized system. Ten thousand mainnet currency rewards. I remember that when the price of LAMB was the highest at that time, the price should be 2 yuan, so 600,000 yuan was distributed to all miners every day to express our apologies to the miners and so on.
When the main network was launched, we reached five major consensuses - block reward distribution model, main network node and space entry and exit mechanism, ERC20 pledged node and space exit mechanism and reward coin balance, LAMBS balance mapping TBB, all verification of Lambda The nodes reach a consensus and support the implementation of these five proposals.
Lambda has done a solid job in many things. And we have left a lot of easter eggs and advantages for students who are interested in technology.
Because the ecosystem is very rich, there are miners, nodes, mining machine manufacturers and various ways of playing, so there are many types of transactions, and various assets can be traded on it. We believe that all assets are tradable, and trading is the essence of the blockchain and the essence of digital currency.
Odaily: We have seen that Lambda currently adopts a dual-token economic model. In addition to the well-known LAMB, there is a brand new currency TBB. Could you please introduce how TBB works in detail?
He Xiaoyang, founder of Lambda:Dual pass is also a way of crossing the river by feeling the stones. Now it is obvious that the design of single pass will cause many problems in the scenario where you want to have actual business logic.
From the earliest development of digital currency to the present, Bitcoin does exist as a single pass, and there are no problems. Because the value of Bitcoin is given by those who hype Bitcoin.
From this point of view, the single-token system is very suitable for digital currency design, that is to say, it is such a currency that is given monetary value by some external force. But later, we discovered more concepts. We expect to use digital currency and blockchain to carry out some kind of link with the actual Internet business, or with some actual business. At this time, the single token design will A lot of shortcomings were exposed.
The reason why Lambda changed to dual pass is actually very simple. First, I think that the so-called impossible triangle concept in the currency circle has become very famous recently, which means that it is impossible for project parties, private equity institutions, secondary markets, and retail investors to make money at the same time. We think that what everyone expected in the early stage is to raise funds through digital currency and then sell them in the secondary market. The token can be rewarded not only to early investors, but also to many users. The concept of a single pass is not possibly done. In other words, it is impossible to accomplish so many functions with one token.
Under the definition of single pass, some people must be cut off.
Our point of view is that it is difficult to have both rights and circulation on the same token. Now in foreign countries, the design of dual pass is also more popular, because it is inevitable to cut leeks with a single pass. Today we can clearly say that any single pass will have an impossible triangle, that is to say, it is impossible for investors, project parties and retail investors in the secondary market to make money at the same time. . There must be problems with this project.
The only possibility is to remove one of them, such as the investor. Then remove the investors and become only the project party and retail investors in the secondary market. In this case, it is possible that he can be established, but at this time many projects will face problems. First, there is no money to develop, and second, the project party may I didnt do it anymore. Therefore, dual tokens may be a better carrier and a way to solve problems. One kind of token represents the rights and interests of investors, and another kind of token represents circulation. This may be a better design.
As for TBB, you dont have to think about it so deeply, it is actually a very simple thing. Miners who provide 1TB of storage have the right to mine 1TB. In such a large storage system, miners may breach the contract, and miners may cheat. Therefore, for the storage system, in order to protect the rights and interests of users and to ensure that user data is not maliciously lost, miners must pledge a certain Money, pledge certain rights and interests to the entire chain.
So this is something that miners must do. Since the miner has pledged his rights and interests, the miners pledge for each TBB is a kind of his rights and interests, and he will form a mining right. When a miner has 1TB of mining rights and actually accesses 1TB of actual storage, the miner can mine LAMB according to the number of TBB. Simply put, each TBB represents a TB mining right.
Odaily: What is the biggest difference between Lambda’s dual-token mechanism and those of other projects?
He Xiaoyang, founder of Lambda:I think everyone can understand that Lambda is based on real business logic, and it cannot be designed as a dual pass at the beginning. During the evolution process, we discovered many changes. First, after we recruited miners, many mining pools quickly appeared. At present, there are probably tens of thousands of miners hanging under several mining pools. The pledge of the second miner may be considered to be a pledge of LAMB by the miner in the early stage, but in the single pass system, the pledge is actually very troublesome, especially when it involves business logic. The pledge on Lambda actually involves business logic.
For example, initially we thought it was reasonable to pledge 3000LAMB for one TB. For miners, the actual physical costs (electricity costs, hard disk costs, operation and maintenance costs, etc.) determine how much the real user (storage user) pays him. But later we found that the currency price of LAMB was linked to the secondary market. After the currency price rose to a certain level, the miners would choose to cash out the LAMB in their hands.
That is to say, if the fee of the pass is constant, it may not attract too much attention from the secondary market. If the fee of the pass is floating and rising, the miners are more inclined to take out the pass and sell it. Instead of continuing to mine tokens. The dual pass solves the problem of the correlation between the currency price and the secondary market. So we think that Lambda must be dual-token, so we can only say that a certain (token) is related to the digital world, and a certain (token) is related to the real world. Only one token cannot complete the business logic of the project.
For example, in our common three-pass token system, one token represents circulation, and one token represents equity or voting rights. If it has some kind of interactive function, it also needs to introduce legal currency. In other words, the three-pass system may be a better system, but it will also make the business more complicated. If needed in the future, we may also consider introducing a more stable currency.
Odaily: After adding the design of the new token TBB, how has the task of the miners changed? Is this change good for miners?
He Xiaoyang, founder of Lambda:It is actually good for miners. In fact, the reason that hinders the development of Lambda is that the price of Lambda is too high. Due to the aforementioned reasons, the number of pledges cannot be changed, so the price of Lambda is too high, which is actually a big obstacle for new miners to enter the system. At the same time, there are many secondary market users, that is, besides miners, there are many secondary market holders, so we can only make the price of LAMB relatively high. When the price is relatively high, miners come in. Very difficult.
After joining TBB, it will be easier to obtain TBB. Many miners have TBB rewards in their hands, and many investors also have TBBs that have not participated in mining. The total number of TBBs is only 1 million, and the price of the token is low. Come to mine LAMB, you can hoard it and not sell it if it is high. TBB is a currency that can be hyped and mined, and it is quite friendly to miners. When the price of TBB currency is low, miners are playing with it, and when the price of the currency is high, the secondary market is playing with it. At least for miners, it is a good thing.
Odaily: This year Lambda successfully launched the main network, so what is the next plan and focus of work?
He Xiaoyang, founder of Lambda:After the mainnet went live, we finally had time to work. After the mainnet is launched, we have time to build something very different for everyone based on this solid foundation.
In the future, we will design a series of businesses. First, expand the business layer. First, we will build a distributed network disk and then a distributed IM. Second, let more users use Lambda. We hope that more users will come to Lambda for storage. Data, let Lambda enter a new journey. Lambda is not only a blockchain project, but also an Internet project. The next step is to do business, so that more currency holders who are not in the secondary market can use the Lambda system.
Only when the system does not appear to have anything to do with the blockchain from the outside, can this signify the success of the project. Before the end of this year, we should be able to see the network disk system and chat system made on Lambda. These are some things we want to do this year.
Odaily: Which exchanges does LAMB plan to list in the future? Will TBB go to college?
He Xiaoyang, founder of Lambda:In the future, LAMB also wants to be listed on three major exchanges, Bitfinex, Binance, and Coinbase. TBBs listing plan is to list 20 exchanges in the future.
