What is Bluzelle?
Bluzelle is a Cosmos-based Layer 1 blockchain built for decentralized science (DeSci) and gaming applications, combining a 10,000 TPS transaction network with integrated decentralized database storage. The network allows developers to store, mutate, and manage data at the database level while relying on on-chain cryptographic verification and cross-chain Cosmos communication.
Leadership and backing
Bluzelle was founded by CEO Pavel Bains and CTO Neeraj Murarka. Bains brings a background in venture capital, digital media, and operations with companies such as Disney Interactive, Electronic Arts, and Nintendo. Murarka is a computer systems engineer with over two decades of enterprise architecture experience across organizations including IBM, Google, Hewlett Packard, and Lufthansa. Based in Singapore with development operations in Vancouver, the project raised $21M in total funding through venture rounds finalized by March 2018.
Architecture and core mechanics
The network runs on a Delegated Proof of Stake (dPoS) consensus mechanism powered by Tendermint and the Cosmos SDK. In addition to core transaction consensus, Bluzelle operates Bluzelle R2, a decentralized storage network powered by IPFS that supports mutable data structures. Unlike conventional permanent chains, data leases in Bluzelle can be updated, extended, or expired based on cryptographic rental contracts. The native token, BLZ, exists both as an ERC-20 asset and a native Layer 1 token. It is the utility asset used for staking delegation and network gas fees.
Transaction fees and access
Network fees follow a gas model denominated in fractions of BLZ. Simple database queries carry no fee, whereas write operations require gas priced per DayByte, which measures one byte stored over a single day. Interoperability is supported through the Cosmos Inter-Blockchain Communication (IBC) protocol and Osmosis bridging, with end users accessing the network via the Keplr wallet or centralized exchanges.
Trade-offs and network considerations
Bluzelle has shifted strategic focus over time, moving from an early general database model to GameFi and subsequently prioritizing DeSci and longevity data infrastructure. Users and validators rely on IBC bridge pipelines to move assets between Ethereum and Cosmos environments, which introduces smart contract and relay dependencies. Data rent economics also require active lease maintenance, meaning records are purged once a paid lease expires without renewal.

Pros and cons
Pros
- Throughput rated at 10,000 transactions per second on Cosmos
- Database queries are free of transaction gas charges
- Storage allows mutable updates rather than paying for permanent bloat
- IBC integration connects liquidity to Osmosis and the wider Cosmos network
Cons
- Expired storage leases purge data automatically unless renewed
- Pivoted focus across general data, GameFi, and DeSci over time
- Requires bridging between ERC-20 and native Cosmos Layer 1 BLZ tokens
Our review
3.3/5
Fair
Bluzelle offers high-throughput Cosmos storage infrastructure for decentralized science, but its ecosystem adoption remains narrow compared to larger smart contract networks.
Bluzelle is a Layer 1 blockchain built using the Cosmos SDK and Tendermint consensus engine. The network targets decentralized science (DeSci) and storage-heavy workflows, pairing a 10,000 TPS execution layer with Bluzelle R2, a decentralized storage module backed by IPFS. Consensus relies on delegated Proof of Stake, with transaction validation handled through its native Cosmos validator set and IBC bridging to Cosmos hubs like Osmosis.
Network operations run on the native BLZ token, which exists both as an ERC-20 asset on Ethereum and as a native Layer 1 token. BLZ pays for computation, transaction gas, and storage leases, while read queries remain free. Instead of permanent immutability that bloats blockchain state, Bluzelle uses a time-based data leasing model calculated in Gas per DayByte. For instance, storing 1,000,000 bytes for 10 days at 2.5 gas per DayByte and 0.002 micro-BLZ per gas costs 0.05 BLZ.
The company behind the project was founded in Singapore by CEO Pavel Bains, who brought experience from Disney Interactive and Panda Stories, alongside CTO Neeraj Murarka, a computer systems engineer with a background at IBM and Google. Bluzelle raised $21M in venture funding by March 2018. While the engineering core has maintained continuous network iterations, including the v11.0 Cosmos SDK migration, the platform has repeatedly pivoted its primary narrative across decentralized databases, GameFi, and DeSci.
Developers handling scientific data distribution, intellectual property tokenization, or Cosmos-native applications benefit from its low storage fees and IBC interoperability. Teams seeking established DeFi liquidity, deep smart contract tooling, or direct Ethereum EVM execution should look to larger Layer 1 or Layer 2 platforms.

Who founded Bluzelle?
Bluzelle was co-founded by CEO Pavel Bains and CTO Neeraj Murarka. Bains holds background experience with Disney Interactive and venture capital, while Murarka has over 20 years of computer systems engineering experience at firms like IBM and Google.
Does Bluzelle have a native token?
Yes, the native utility and governance token is BLZ. It is used to pay network gas, buy storage leases, secure the network through validator staking, and participate in governance.
What fees does Bluzelle charge for transactions and storage?
Transaction fees cost pennies, and data queries are free. Storage is paid in BLZ using a leasing calculation based on gas per DayByte, where storing 1 MB for 10 days costs approximately 0.05 BLZ.
Which blockchain ecosystem does Bluzelle belong to?
Bluzelle is a standalone Layer 1 blockchain built on the Cosmos SDK and Tendermint engine. It connects to the broader Cosmos ecosystem via the Inter-Blockchain Communication protocol and links to Ethereum through an ERC-20 token bridge.
How does Bluzelle handle data storage?
Bluzelle R2 provides decentralized mutable storage powered by IPFS. Rather than storing files permanently, users create cryptographic lease agreements that persist data for a chosen number of blocks or days.
