Ethereum is a smart contract platform that enables developers to build tokens and decentralized applications (dapps). ETH is the native currency for the Ethereum platform and also works as the transaction fees to miners on the Ethereum network. Ethereum is the pioneer for blockchain based smart contracts. Smart contract is essentially a computer code that runs exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. It can facilitate the exchange of money, content, property, shares, or anything of value. When running on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. Ethereum allows programmers to run complete-turing smart contracts that is capable of any customizations. Rather than giving a set of limited operations, Ethereum allows developers to have complete control over customization of their smart contract, giving developers the power to build unique and innovative applications. Ethereum being the first blockchain based smart contract platform, they have gained much popularity, resulting in new competitors fighting for market share. The competitors includes: Ethereum Classic which is the oldchain of Ethereum, Qtum, EOS, Neo, Icon, Tron and Cardano. Ethereum wallets are fairly simple to set up with multiple popular choices such as myetherwallet, metamask, and Trezor.

Lambda is a fast, safe, and scalable blockchain infrastructure project, which provides decentralized applications (DAPPs) data storage capabilities with unlimited scalability and fulfills services such as multi-chain data co-storage, cross-chain data management, data privacy protection, PDP, and distributed intelligent computing through logic decoupling and independent implementation of Lambda Chain and Lambda DB. Through the logical decoupling and separate implementation of Lambda Chain and Lambda DB, we provide infinitely scalable data storage capabilities to decentralized applications and achieve Multi-chain data cooperative storage, cross-chain data management, data privacy protection, data ownership proof, distributed intelligent computing and other services. Additionally, as the underlying service of blockchain, Lambda Chain provides millions of requests per second (RPS) through Sharding technology, which can grow as the scale of the system expands; and it also offers technology service capabilities for future unlimited expansion through sub-chain technology. We believe that all storage projects follow the core requirement of Provable Data Integrity.Also, it is crucial for data projects to store data in an infeasible storage node and make them trusted and secure, in the academic world, there are mainly two approaches which are Provable Data Possession (PDP) and Proofs of Retrievability (POR) depending on the usage scenarios. Lambda has applied these two approaches in blockchain through academic research and engineering verification, which has eliminated the core obstacles of decentralized storage.
