1. Lambda Blockchain (Singapore)
Lambda Blockchain is a project dedicated to developing a data warehouse based on blockchain which aims to compete with Filecoin, Stirj, and Sia. The project focuses on problems that competitors cannot solve: the challenge of changing static files stored in the cloud storage, as well as the challenge of searching for information in files.
Lambda plans to resolve these issues so that full DApps work will be possible. The Lambda technology is different in that developers can use the project code and change it in accordance with the Apache (NYSE:APA) license. It is possible to deploy private networks - in this case, the public link is used to automatically audit and store immutable data.
The Lambda architecture is represented as follows: Lambda Chain = actual blockchain, Lambda p2p is the addressing system at the network level, Lambda DB are database clusters, Lambda ABE handles gateway for accessing the database, with multilevel attribute-based encryption. Lambda TPA Chain is responsible for checking data for integrity (consists of several validators), Lambda Agent is a monitoring system that provides memory data storage, performance monitoring, security monitoring, and metric data loading.
In principle, everything is logical and simple. Nodes (validators) are selected by VRF (Verifiable Random Function), and the main consensus is BFT (implemented by Tendermint). In order to avoid repetitions and conflicts, the nodes agree with each other in accordance with the Proof of Space Time (PoST) - whoever is fastest is the first.
Moreover, PoST is not created by Lambda itself but taken from Filecoin. But in Lambda, everything is achieved by clustering (shards). At the moment, test environment display speeds of 5000tps, with the generation of blocks in 15 seconds.
Lambda Storage Network Members:
V (Validators): keep nodes on the mainframe, pack transactions and
generate blocks, get the most tokens. In addition to the mainchain, validators perform their functions of checking, packing transactions and generating blocks and sidechains. Validators generate tasks and formulas for storage terminals that calculate and return digital vectors back to the validator. The validator then checks for successful completion of the storage terminals’ task based on the metadata and digital vectors.
N (Nominator): stakers are able to trust the security deposits to validators.
F (Fisherman): controllers who monitor the behavior of validators. They work in the mainchain, checking on its sidechain blocks. If a Fisherman finds an error in the mainchain block, then a more serious test begins that involves block recovery. And here lies one of the unique features of lambda - there will be no forks, because the wrong blocks in sidechains are simply replaced, or the correct information is restored in them due to what is recorded in the mainframe. Then the repaired block is simply sewn back into the blockchain.
Tokenometrics of the Lambda project:
Total Supply - 10 billion LAMB, 40% of tokens will be mined by miners. Team’s and advisers’ tokens and are locked for 3 years. 3 billion tokens (30%) were allocated to the token sale. $15 million was raised at the private sale. Tokens of the private sale participants will be unlocked within 10 months. The first unlock (5%) is in February. The price of the token during the private was $0.006. The total raised was $15.1 million out of the planned $20 million. Tokens are used to pay for network services, to encourage holders of nodes and validators and check the integrity of the network.
The Lambda project team:
In general, the team has a good information footprint. And most of the team members have enough competence to create a distributed network.
The founder He Xiaoyang graduated from Beijing Institute of Technology with a degree in Computer Science. He was a co-founder of OneAPM, an analytics optimization software. He has been working there for more than 9 years. He worked at BEA as a software development engineer for R & D (this company was later bought by Oracle (NYSE:ORCL)).
Lambda project partners:
BitMax is responsible for project listing.
Perlin is a platform based on DAG and Avalanche protocol.
OneAPM is engaged in analytics software for its optimization in business and in enterprises.
Investors: ZhenFund, Metropolis VC and Dfund, as well as Funcity Capital, Ceyuan Digital Assets, BlockVC, Bluehill, Data Foundation, and Sparkling Star Capital. Of the more famous investors: FBG, BitMain, IOST.
Lambda is currently trading on Bitmax, Huobi, Bilaxy and Hotbit exchanges. It is also known that they won the voting for listing on Bibox - listing is expected in the coming days. The graph shows that the start of trading on December 29 began a little higher than the private price (approximately 0.08 USD, 0.006 USD private price). As of 01/05/2019, the price is closer to the level of first tier (0.01 USD for LAMB).
In conclusion, we can say that Lambda is not a project for holding tokens. The interaction of miners is poorly spelled out in White Paper, very little attention is paid to the most important category of miners - holders of nodes with data. The Github depository is not very well designed in terms of the functionality of sorting of developments, MVP also looks somewhat doubtful. Advisers appear weak.
On the other hand, the team looks very decent, and judging by the interviews they understand the subject matter of the project and the blockchain in principle. Community managers are competent.
Project evaluation by the Tokenbox team: 6.5 / 10.
