BLUR is a cryptocurrency built with privacy in mind. Take a first-hand role in protecting yours.

About the Blur Network

The Blur Network (BLUR) is a privacy-focused peer-to-peer network, built upon the premise that privacy is not compatible with centralization. Blur makes use of a private, standalone blockchain in which transaction participants and amounts are hidden, to enable a degree of privacy that is impossible on a transparent ledger, such as Bitcoin.


The Blur Network has been designed to address the direct threats to privacy and security resulting from specialized mining hardware and centralized mining pools. Miners have turned to these to reduce variance in block reward payouts from mining. Our network views these current solutions as detrimental to decentralization. Centralized pools and limited access to specialized mining hardware place the security of existing networks into the hands of few.

Out of a desire to keep mining hardware accessible to hobbyists, the approach of hardware-specific resistance has arisen. However, this approach limits access to compatible hardware even further. To compound this, resistance to hardware is something of a perpetual cat-and-mouse situation. Instead of subscribing to this philosophy, Blur seeks to build an ecosystem that is inclusive for all mining hardware. This manifests itself as an experiment we are calling The Fractal Multichain, which is planned to feature discretionary and hardware-specific Proofs-of-Work. Each chain will be weighted inversely in value, to a single devices relative hashpower (compared to a CPU).

The current chain will become the base-value chain (modular chain values will be denominated by BLUR units, proportionally). As such, BLUR's current blockchain will remain central to our attempt at favoring multi-purpose hardware, while we bring the other chains, designed for specialized hardware, online as well. In CryptoNote blockchains, emission is biased to favor early adopters. Subsequent, in-tandem chain launches will seek to leverage this aspect of emission curves, to incentivize away specialized hardware, theoretically resulting in less competition for CPU miners, on the base chain.


CryptoNight-Dynamic, our novel application of the CryptoNight algorithm was developed to maximize decentralization of network hash power. This is accomplished by favoring CPU-specific strengths, to enable “mining hardware” to extend to anyone who owns a computer. The algorithm dynamically varies the amount of iterations that are performed at various points in its computations. The iteration count is a direct function of the current block's timestamp and the previous block's hash.

This translates to mean that Blur’s algorithm varies dynamically, on both intra-block and inter-block bases. The result is an algorithm that changes roughly once every five seconds, with each block's specific iteration count being directly dependent on the hash of the block before it and the current time. These specific aspects of the algorithm make an active connection with the network necessary, for computing the proof-of-work for each block. All information is taken directly from the block header. Therefore, mining with specialized hardware is possible. However, nodes with direct access to the historical blocks will perform with an advantage due to not needing to relay this information across the web, or between clients.


Key Features of BLUR


Selective transparency allows BLUR to be much more fungible, and censorship-resistant than transparent blockchains. Amounts and participants are obfuscated when sending or receiving BLUR. This means users can decide precisely who may view their transactional information. This is impossible on Bitcoin's network, where anyone can look up addresses and associated balances.

The Blur Network runs on a custom hashing algorithm, called Cryptonight-Dynamic. The algorithm changes dynamically every second five seconds, on average. The algorithm's calculations, which are dependent on the previous block's hash, the current block's height, and a UNIX timestamp, determine a differing amount of iterations, both between and within each block tha is mined. Our goal is facilitating CPU-centric mining, devoid of illogical mining pools. The icon above is a hyperlink to a paper detailing the need for a solution in response to miner centralization.


The Blur Network seeks to enable individuals to transact in BLUR without the variable of "trust." This is made possible by the CryptoNote Protocol, which employs cryptographic primitives to secure the transactions. Users can generate a keypair, from which addresses are derived, without ever connecting to the internet. This means we cannot and do not control who chooses to use the Blur Network. The Cryptonote Protocol whitepaper can be found by following the hyperlink above and is annotated with commentary from researchers at Monero Research Labs.
