Summary Blockchain technologies are propelling the next generation of the Internet, known as the Internet of Value. In the current Internet, the technologies are centralized which leads to extensive challenges in security, scalability, and privacy. In the blockchain powered New Internet, everything from infrastructure to the consumer applications DApps themselves are decentralized. Without these decentralized components, the New Internet would not be able to run efficiently and scale to massive use. The table below shows how the New Internet relates to the Current Internet. Bluzelle Networks Pte. Ltd. and it’s technology plat, called Bluzelle, fills a need and is complementary to the other components to make the New Internet complete. Bluzelle is a decentralized service that provides on-demand, scalable databases. It is for software developers who are dissatisfied with the costs, limited scalability, and complexity of existing database systems. For example, unlike running an AWS Mongo server, Bluzelle is low-cost, quick to deploy, provides high perance, and has a solid scalability path. Bluzelle is the right fit because it provides enterprise-grade database services at a price for all Decentralized Application DApps developers.Bluzelle uses idle computer hardware by incentivizing people to rent out their resources to create a decentralized crypto-economic database network. The producers aka farmers provide resources in the of CPU processing power, memory, permanent storage, and network connectivity to enable database shards to be stored with Ecosystem Components The Current Internet The New InternetApplications Facebook StatusOperating System Microsoft Windows EthereumFile storage Amazon S3 FilecoinDatabase storage management Oracle BLUZELLEPrivate and Confidential by Bluzelle Networks 4sufficient replication to guarantee availability and redundancy. Producers demonstrate they successfully stored data by responding to Bluzelle’s “proof of storage” and “proof of redundancy” challenges, and upon a successful challenge, are rewarded with Bluzelle Tokens BLZ. The consumers software developers use Bluzelle s database services provided by the collective of producers, and in turn pay for these services using the Bluzelle Tokens. They have control over attributes that dictate how and where their data is shared and stored. These attributes affect the BLZ cost for these services. Moving forward it should be noted that all references to the company is Bluzelle Networks and all references to the product is Bluzelle.Feature DescriptionHighest privacy Bluzelle employs cryptography and sharding techniques to provide a privacy guarantee. High reliability Bluzelle redundantly stores tiny pieces of data on nodes across the globe, eliminating any single point of failure.Enterprise scalability Bluzelle stores data in a unique, distributed and intelligent manner that is able to provide enterprise-level scalability.Data immutability Bluzelle leverages blockchain technology so that once data is stored to such a network, it is impossible to change that data. High perance speeds Bluzelle dynamically adjusts the number and location of nodes sharding the consumer’s data to meet perance metrics. No intruders Bluzelle’s use of consensus is the only by which updates to the network can be accepted as the “truth”.Low cost Bluzelle operates no data centers and has zero capital costs. All computer resources are provided by participating “farmers”.Private and Confidential by Bluzelle Networks 53. About Bluzelle Networks 3.1. Mission Our mission is to improve the lives of a billion people through blockchain. We believe that blockchain-powered applications are a key catalyst for financial inclusion.3.2. History Starting in 2014, Bluzelle Networks saw that for the world to get better financial services, banks and insurers would require new technical infrastructure. Their legacy systems were expensive to maintain, and blockchain based applications would provide better and cheaper products for end customers. We created as a middleware technology with application libraries that abstracts the complexities of managing blockchain applications. Just like Oracle made it easier for enterprises to manage relational databases, we made it easier for enterprises to manage the blockchain. Over the past 15 months, our proven technology has met real business needs through numerous fintech projects including➢ An Ethereum-based KYC Shared Ledger for a consortium of international banks.➢ An Ethereum-based insurance plat for major Asian insurer MSIG.➢ An Ethereum-based consumer mobile insurance product by AIA.➢ A Ripple-based cross border payments POC for Temenos - a world-leading core banking system with thousand of customers.➢ Channel partnerships with KPMG, Microsoft, British Telecom and Happiest Minds to bring Bluzelle to their portfolio of customers. Bluzelle Networks was named to the Global Fintech 100 by H2 Ventures and was appointed by the World Economic Forum as a Technology Pioneer for 2017. Previous winners include Google, Spotify, Twitter, AirBnB amongst others.Private and Confidential by Bluzelle Networks 63.3. The Evolution of Bluzelle Working with enterprise customers revealed one critical challenge for widespread adoption of blockchain applications the management of large amounts of data. By evolving our technology to include data management services, we target all software developers, including small to medium businesses. We provide all developers with an enterprise-grade database management service at an economical price. Bluzelle is a decentralized service that provides on-demand, scalable databases. It is for software developers who are dissatisfied with the costs, limited scalability, and complexity of existing database systems. Bluzelle is low-cost, quick to deploy, provides utmost perance, and has a solid scalability path. Bluzelle provides enterprise-grade database services at a price for all DApp developers. Private and Confidential by Bluzelle Networks 74. The Current State Of Database Services Our world is driven by software, automation, and connectivity that requires the generation, management, storage, and retri of enormous amounts of data. Traditionally this has been solved with a database that requires 1 a server to host on, 2 a database management system, 3 an administrator, and 4 the high costs to implement and manage them. Cloud computing marginally improved upon this. However, features like resilience, replication, availability, non-repudiation, transparency, immutability, perance, and data integrity were not guar
