What is Bluzelle Coin (BLZ)- A Decentralised Database for dApps

Update - 2018.02.07

What is Bluzelle?

bluzelle ico

Bluzelle is a decentralised database service for dApps (Decentralized Applications). It is for dApp developers who are dissatisfied with the costs, limited scalability, and complexity of existing database systems. While several companies, including Filecoin and Storj, are already working on decentralized file storage, Bluzelle is targeting the databases that keep data quickly and easily accessible for websites and applications to pull from.

Bluzelle’s approach is to provide something like key/value database.
Data is sharded and sits on multiple nodes all over internet. The node closest to user or with best connection serves the data from appropriate shard.

Major Advantages of BLZ:

Reliable ‘swarm’ technology
Bluzelle stores tiny pieces of data on groups of nodes (swarms) across the globe, eliminating any single point of failure.

Boundless scaling ability
Bluzelle’s algorithm stores data in a unique network model that doesn’t depend on data centres, and is able to scale database services in an instant.

High speed on the fly
Bluzelle dynamically adjusts the number and location of nodes sharding your data to reduce request time and overall performance.

Guaranteed Privacy
Bluzelle employs cryptography and sharding techniques to provide a privacy guarantee.

High Reliability
Bluzelle redundantly stores %ny pieces of data on nodes across the globe, eliminating any singlepoint of failure.

Enterprise Scalability
Bluzelle stores data in a unique, distributed and intelligent manner that is able to provideenterprise-level scalability.

Data Immutability
Bluzelle leverages blockchain technology so that once data is stored to such a network, it isimpossible to change that data.

High Performance Speeds
Bluzelle dynamically adjusts the number and location of nodes sharding the consumer’s data to meet performance metrics.

No Hackers
Bluzelle’s use of consensus is the only method by which updates to the network can be accepted as the “truth” – making the data hack-proof

Low Cost
Bluzelle operates no data centers as all computer resources are provided by network producers who earn funds and pass the savings to consumers.

How to buy Bluzelle – BLZ?

You can’t buy it directly for fiat. There has to be a middle step in form of buying BTC, ETH or LTC on some of the exchanges that support fiat/crypto pairing. You can check detailed guide on how to buy coins for fiat on some of the more popular exchanges:

Coinbase, Coinmama, Cex.io, LocalBitcoins.


After that, you transfer the bought BTC/ETH/LTC to exchanges where this token is traded. As of right now, this token is traded on:

Binance, IDEX.

Token Info

Bluzelle team didn’t just create one token, it created two.

The first token is BLZ. It is the ethereum-based ERC-20 token that was sold during the ICO. BLZ will eventually be used to purchase the second, BTN, which was created only for use on the Bluzelle platform.  Ethereum has serious scalability issues, has a long and non-deterministic confirmation time, and gas costs make a single blockchain-based payment approach infeasible. The BNT token enables high speed microtransactions to occur, and is actually an approach many services use to alleviate the Ethereum issues.

  • Symbol: BLZ
  • Token sale opening date: 18. Jan 2018 
  • Token sale closing date: 2. Feb 2018 
  • Concept: Bluzelle is a decentralised database service for dApps (Decentralized Applications). It is for dApp developers who are dissatisfied with the costs, limited scalability, and complexity of existing database systems.

Token Use

1. Buy BLZ tokens on a crypto-exchange using ETH, BTC or other forms the exchange allows.

2. Send BLZ tokens to the Bluzelle Token Gateway’s smart contract via Ethereum. The gateway will issue new BNT tokens to the user’s Bluzelle network wallet.

3. The user now has BNT tokens, and is free to parDcipate in the network as a consumer.

Our Opinion

Bluzelle is still relatively early in its development roadmap. Further, it has yet to establish the necessary partnerships that will ensure a successful launch.

Only 33% sold for crowdsale. That should be worrying as 67% of tokens go to Bluezelle and cronies. Pretty astonishing distribution.

There was also too much hype by some crypto celebrities who are known to do the hyping if paid by crypto teams.

This is nice idea and there is big room for growth but there are some some competitors already in the market, like MaidSafe. However, it looks like MaidSafe is more of a file-based service (based on their youtube promos). They decentralize the storage and access to files.

According to Bluzelle’s FAQ on the topic of decentralize file storage:

They operate purely on the manipulation of files, which has a very different application. File decentralization can be used for access to website resources (images, stylesheets, html, etc) or to enable globalized scalable access to documents. Bluzelle’s data decentralization services would be consumed by software at a more intimate level, that is opaque to the end-user, replacing existing database systems.
