The Blockchain that Brings Privacy to the Masses


In 2009, Satoshi Nakamoto launched Bitcoin unto the world, and with it, a expertise with the potential to outline the subsequent century: blockchain.

As a default, blockchains safe transactions with a degree of privateness exceeding that which is achievable by centralized fee networks. Consensus mechanisms corresponding to Proof of Work (PoW) and Proof of Stake (PoS) present strategies for decentralized consensus, permitting cryptocurrency networks to settle transactions and not using a centralized authority.

Nevertheless, consultants amongst the cryptocurrency group are expressing concern over whether or not this degree of privateness is sufficient given developments in fashionable anti-privacy applied sciences.

Blockchain: Non-public or Not?

Banks and centralized fee networks like Visa haven’t any selection however to report private transaction knowledge – sender and receiver names, quantities, occasions, areas, and infrequently the varieties of items or providers bought – with a view to facilitate the motion of cash and shield customers from fraud.

Whereas blockchains are advantaged on this regard, the privateness they supply shouldn’t be excellent. Sender and receiver pockets addresses, in addition to transaction quantities, are saved completely on blockchains for all to see. Bitcoin.org describes how this is applicable to the Bitcoin community:

“All Bitcoin transactions are public, traceable, and completely saved within the Bitcoin community. Bitcoin addresses are the one data used to outline the place bitcoins are allotted and the place they’re despatched. These addresses are created privately by every person’s wallets. Nevertheless, as soon as addresses are used, they turn out to be tainted by the historical past of all transactions they’re concerned with. Anybody can see the stability and all transactions of any deal with.”

To fight this, many have turned to tumbling providers that ship transactions by a plethora of pockets addresses in an try to obfuscate transaction origins and locations. Nevertheless, each researchers and adversaries have had 12 years to crack high-volume blockchain transaction tracing. As we speak, blockchain evaluation software program makes it attainable to quickly hint tumbled transactions and affiliate pockets addresses with one another.

Additional, most individuals enter the cryptocurrency market by centralized exchanges like Coinbase which require their members to go KYC (Know Your Buyer), a course of used to confirm the identities of people in accordance with rules. Which means that all transaction chains originating from centralized exchanges are traceable and simply tied to their members’ actual identities.

Clearly, an improve is required if our monetary privateness, and to an extent, our freedoms, are to outlive fashionable blockchain tracing strategies and encroaching rules.

Bettering Blockchain Privateness

Some cryptocurrency initiatives, aptly named “privateness cash”, have taken it upon themselves to resolve the privateness gaps in previous-generation blockchain protocols.

Monero, Zcash, and PIVX are in style choices, however concern over whether or not they have saved up with evolving privateness wants grows throughout the cryptocurrency group. Many safety consultants are as a substitute turning to Navcoin, a future-oriented privateness mission that helps public transactions by its NAV token and utterly personal transactions by its xNAV token.

xNAV makes use of Navcoin’s self-developed privateness protocol “blsCT” to guard transaction knowledge from prying eyes. BlsCT does so by combining all transactions inside a block into one, then distributing xNAV tokens to wallets with out revealing their addresses or balances to the general public. This successfully breaks the hyperlink between transaction inputs and outputs, making it not possible to establish which wallets participated wherein transactions.

xNAV takes person privateness even additional by fixing a menace issue that almost all cryptocurrency customers will not be conscious of: IP tracing.

When a transaction is shipped by a cryptocurrency community, the sender’s IP is revealed to neighboring nodes. Which means that transactions could be related to IP addresses, making it attainable to hint the bodily origination of transactions.

xNAV solves this utilizing one other progressive expertise, Dandelion++. With it, sender IP addresses are initially despatched to a single node, which then connects to a special node and acts as the unique sender. This chain continues a random variety of occasions, obfuscating the unique sender’s IP deal with, making it not possible to correlate transactions with IP addresses.

A Excessive Utility Privateness Platform

Whereas Navcoin’s privateness protocols are spectacular, they aren’t the one causes behind Navcoin’s latest consideration.

Navcoin will quickly start providing privateness as a service, transitioning right into a excessive utility privateness platform that can be utilized by different cryptocurrencies to realize complete privateness. It will drastically enhance the demand for Navcoin, as all community charges shall be paid with it.

As a part of its choices, Navcoin’s platform will assist Non-public Tokens and NFTs, permitting customers to mint NFTs together with tokens pegged to the values of different belongings, all with the identical privacy-preserving elements utilized by xNAV.

The implications of this are broad – together with the potential for customers to mint personal variations of cryptocurrencies, and commerce privately, eradicating KYC from the method of gaining publicity to mainstream cryptocurrencies like Bitcoin and Ethereum.

As revolutionary as it’s, blockchain expertise wants an improve if it’s going to maintain up with the anti-privacy ways of establishments and adversaries. Navcoin leads the way in which with xNAV, an progressive privateness coin that solves in the present day’s privateness considerations.
