February 3, 2021, marked an important event for dApps to realize their full potential with the release of Bluzelle mainet. Bluzelle is a decentralized, on-demand, and scalable database service for dApps. Designed for storing massive amounts of data exchanged by dApps, it is a decentralized alternative to the Oracle databases. The blockchains such as Ethereum enable the deployment of applications in a decentralized setting. But these platforms are not designed for the data storage and management requirements of applications. Storing large amounts of data on a blockchain like Ethereum is slow and extremely expensive. The high Ethereum gas price forces dApps to store their data in some centralized services, meaning they aren’t truly decentralized and are susceptible to failures. Whereas, Bluzelle is a proof of stake decentralized database for Web3, powered by Cosmos and its BFT technology Tendermint. It can be used for dApp developed on any blockchain. You can check the status of the mainnet here. It has the capability to process 10,000 transactions per second and interoperate across any chain. Protecting businesses from data breaches, network failure, and performance issues, Bluzelle effectively serves as an “Airbnb of databases,” with developers paying for storage space and read/write access to the decentralized database. Token Economy Bluzelle is powered by its native token BNT, and an Ethereum-based ERC20 token, BLT. Out of a total token supply of 500M, 165M tokens have been sold. Currently trading at $0.145, BLT tokens are available for sale on Binance and Huobi exchanges. Just a few days after its launch, the coin is trending on Coingecko, a famous cryptocurrency ranking website. Timeline Bluzelle has successfully launched two incentivized testnets, Swarm of Duty 1 in July 2020 and Swarm of Duty 2 in December 2020. Notably, Bluzelle recorded 200+ validators participating in these testnets. The release of the mainnet follows the success of the soft mainnet, which was launched back in August 2020. It has attracted extensive participation from the Bluzelle community. Currently, Bluzelle is looking forward to its Polkadot integration, making Bluzelle interoperable with a whole universe of other blockchains. Bluzelle is bringing decentralized database capabilities to projects building on Polkadot’s Substrate framework. Bluzelle’s database services will become available on both the Polkadot mainnet and its test-network counterpart, Kusama. Bluzelle’s Comparison with Other Databases Source: https://ift.tt/2DMtVcn Advantages over earlier and present Database systems: No points of failure; data distributed among multiple nodes of a swarm that are geographically dispersed across the globe. Thus it is Immune to local outages. Scales efficiently; both horizontally and vertically by using swarms. Provides the highest privacy; employs cryptography and sharding techniques. Immutable data storage and leverages blockchain technology. Once data is saved, it is impossible to change that data. No performance limitations; reduces data latency by retrieving data from the nearest nodes on leaf swarm, and retrieving shards of data in parallel from different swarms that contain those shards. The protocol dynamically adjusts the number and location of nodes sharding the consumer’s data to meet performance metrics. No Intruders; use of consensus for any update to the network. Low cost; the vast majority of computer resources are provided by participant producers. So there are only a few data centers. Users Consumers: Customers of Bluzelle are software developers who are building decentralized applications and want to use the database to store off-chain data at a low cost. They spend Bluzelle tokens (BLZ) to store and retrieve data. Sends encrypted data. To store data to Bluzelle, consumers need to sign a lease and specify the length of time that the data will persist. The lease is a cryptographic contractual agreement between the user of the database, and the blockchain itself, that guarantees that in return for the gas expended to create that data, the data will be stored securely and be highly available to the user for the length of time of that lease. Consumers store encrypted data on the Bluzelle network and pay for its use by using gas. They pay for “Gas per DayByte.” The “DayByte” refers to one byte being stored for one day. So, “Gas Per DayByte” refers to the number of gas units for each DayByte. Validators: These are the people and businesses with spare disk capacity to rent out their space and earn extra income. Compare it to AirBnB but instead of physical space it is digital. They provide resources to the network in return for Bluzelle tokens. To be a validator, users are required to put a proportional stake of tokens to ensure high-quality service. This stake serves as a requirement for participation and as a strong economic deterrent from bad behavior. Bluzelle Architecture With Bluzelle, the data is stored on a network of 13 or more nodes. Each such network is called a database zone, and all zones are synced together. No node is a leader, ensuring … Continued
