Bluzelle:A Decentralized Database for the Decentralized Internet

The decentralized internet is growing fast and for it to continue that growth like the internet before, it needs a range of specialist products and services to provide the foundation for that to happen.

Forgetting cryptocurrencies for a second, the real activity that is interesting most people within blockchain technology is the number of developers currently building decentralized applications (dApps) on platforms such as Ethereum.

Bluzelle spent the last several years developing blockchain applications for companies like HSBC, AIA, OCBC, and others. It was during this time they discovered the need for a decentralized database for the blockchain world.
Bluzelle is a decentralized, on-demand, scalable database service for dApps. It fills a need and is complementary to the other components that make up the decentralized internet. Without these decentralized components, the decentralized Internet would not be able to run efficiently and scale to massive use. Bluzelle is the missing piece of the decentralized internet.

Blockchain technologies are propelling the next generation of the Internet. Protocols like Ethereum are a platform for launching decentralized applications (dApps) that will change the way products and services are consumed. These dApps will exchange massive amounts of data that need to be stored and managed. The problem is blockchains like Ethereum are not designed for data storage and management; doing so would take up too much space and slow the entire system down.

Not only that, it’s estimated that in five years there will be over 20 billion connected devices that require the generation, management, storage and retrieval of enormous amounts of data. With all these applications producing more and more data, present database management services from Microsoft, Amazon and Oracle are under-equipped to meet the needs of businesses. There are problems centered around performance, reliability and scalability. These can lead to data breaches resulting in massive amounts of data theft. Credit scoring company Equifax recently had 200M records stolen. This could have been prevented by a decentralized database.

The need for file storage systems is being served by the likes of Filecoin and Storj. However, dApp developers also need data storage & management systems that are flexible enough to allow fast and simple data queries if they are to continue building the full range of services that are possible on the decentralized internet. Bluzelle is a decentralized database that solves this problem.

As well as needing database storage rather than file storage, dApp developers also know that the immutability of data on the blockchain can have negative as well as positive effects. Not only has data immutability been considered an unreasonable and unacceptable constraint to data storage situations for a long time, it can be a deal breaker in software projects. Bluzelle leverages the distributed ledger technology of blockchain but is mutable, thereby making it useable for all manner of real world software development needs.

Bluzelle is a decentralized database service for dApp developers. To ensure developers get the highest throughput in performance, reliability and scalability, Bluzelle implements swarming technologies. A swarm is a large group of nodes (computers) that work together to store and manage data. Nodes in these swarms can go down and new nodes can come up with minimal impact on the network.

Bluzelle combines blockchain principles with sharding and partitioning concepts to create a marketplace for data storage and management. It can provide a decentralized database that can grow and scale as per a product’s needs.

Performance – Bluzelle can reduce latency by retrieving data from the nearest nodes on the leaf swarm, and/or increase speed by retrieving data in parallel from the fastest nodes on the leaf swarm.
Reliability – Using the concept of fog or swarm computing, Bluzelle follows a model where every unit of data is 100% replicated in a single leaf swarm amongst a swarm of swarms.

Scalability – Horizontal scaling is a cornerstone of the Bluzelle architecture, where every swarm is another “unit” of horizontal scaling at the metaswarm level. Within every leaf swarm, every node acts as yet another agent of horizontal scaling at the leaf swarm level.

Bluzelle will target three main groups in its journey towards becoming recognized as a mainstream product like Oracle. The first is the dApp developers, who are the early adopters and are already taking advantage of complementary decentralized technologies. Next there are the small and mid-size developers writing common web, mobile and hardware applications, who will be the early majority. Finally, Bluzelle will engage the enterprise software architects once they’ve seen that other developers have been validated in their approach.

The roadmap for Bluzelle is split into two distinct phases, first the minimum viable product (MVP) and then the post-MVP product releases. This year, the focus will be on single-swarm, NoSQL key-value pair RAFT consensus storage facility, driven by a minimum stake of BLZ ERC-20 tokens on the Ethereum blockchain.

This will lead up to the release of the MVP in April 2018. Later in 2018, development will focus on PaaS integrations and NoSQL documents, while three more stages in 2019 will cover features such as proof of storage, vertical partitioning and attack tolerance.

Bluzelle is a utility token powering a consumer-producer network. Consumers are all the dApp developers who will pay in BLZ tokens to store and manage their data. Producers are the people who rent out their hardware space to the network and earn BLZ tokens. So instead of paying for a high-powered machine and electricity to mine Bitcoin, people can use their computer at home to earn BLZ.

Using a token solves a fundamental problem with current payment systems. Bluzelle can charge in real-time, avoid merchant fees that come with traditional payment systems, and manage foreign exchange risk. All these combine to offer a lower-cost solution for customers.

The public sale will be in late November and will have a hard cap and there will be a limit on how much people can contribute. This is to ensure that there is wide distribution of the token as it will be needed by millions of developers around the world. There will be a pre-sale and registration is now open.
