Any alternative outside Public Blockchain

[Bravut]

    Am new in this community,the rapid increase in technology and mathematics related to Bitcoin makes me confuse,am also concerned  about the safety of clients data since all transactions are done on a single public network.
 I brought up this topic because I want more explanation,if there is any development or means outside of the public Blockchain that also stores client data to ensure more privacy. I also learnt about lightweight wallet that connects to full node before any transaction,why is it so.....
Pardon me,if am not expressing my points clearly
 The mathematical expressions is hectic,is there any method or recommendations for me  to begin with so I can assimilate on the Technicals of Bitcoin. And unravel it's possibilities,not for me to be just a Bitcoiner who knows only how to hold and sell but also technically oriented about Bitcoin

There's nothing to be confused about mate. You have to know that while transactions and data on the Bitcoin Blockchain are public and accessible to anyone, users identities are not directly revealed. they are pseudonymous, which means you can't know a users identity just by looking at the transactions on the Blockchain. Although with careful analysis user data can sometimes be traced, especially with the rise of centralized bodies that require Know Your Customer (KYC) processes, removing user privacy. Satoshi didn't create Bitcoin transactions to be completely untraceable and had his reasons.

there is any development or means outside of the public Blockchain that also stores client data to ensure more privacy.

To help improve privacy,  there are methods like coinjoins, mixers, and coins like Monero that prioritize user transaction privacy. Though you should be careful while using mixers as your funds might be at stake. Mixers are centralized and you are literally handing the safety of your funds to them and hope they return some clean coins.

Bitcoin is quite broad to some extent but the technical knowledge of Bitcoin is most times said to be confusing but if studied over a little time one could get aquatinted with a basic knowledge. it's more easier to understand Bitcoin techs if you have a basic technically knowledge, but you could learn get a background knowledge from the website learnmeabitcoin[1] it's made easier for everyone to understand.

There have been some so called alternatives to Blockchain that has evolve over time and it's claimed to have gain more interest of the people in recent times[2], it includes a decentralized storage like storj and IPFS[3] you can read up from the web page. but in all Blockchain is still more reliable.

The light node also know as light client connects to full nodes for any transaction because it uses a smaller storage compared to the full nodes and basically the light client depends on the full nodes for information validation and verification instead of proceed transactions directly from any third party it relay on the full nodes for a correct information[4].

Like I said earlier you can visit learnmeabitcoin.com[5] to get a background knowledge of Bitcoin tech, you can also read the GitHub version of mastering Bitcoin to understand more better[6].

Client data? If you want to store client's arbitrary data (not holding client's Bitcoin), why don't just use traditional server or database?

By increasing the number of places where the client information is stored, you are not ensuring the privacy of those clients, you do exactly the opposite: you widen the attack surface by artificially creating additional points of failure. All transactions in the Bitcoin blockchain are pseudoanonymous in their nature, but you can increase the level of anonymity by employing third-party services,  solutions or wallet features such as CoinJoin, CoinSwap, regular coin control, and by paying attention to transactional hygiene.

Yes. Transactions made off of the blockchain can be private using Lightning, which is a non custodial peer to peer messaging network built on top of smart contracts secured on the main Bitcoin chain.

Also, transactions made on the blockchain can be made private by participating in a non custodial Coinjoin transaction. BTCPay Server's coinjoin plugin, Trezor's coinjoin account, and Wasabi Wallet are all able to turn your coins anonymous without leaving any traces behind or trusting any third parties with your data.

There's different tradeoffs for wallets:

Full node: Maximum privacy, full consensus rule validation, slow sync
Filter wallet: Maximum privacy, no consensus rule validation, fast sync
Light wallet: No privacy, no consensus rule validation, instant sync

All of these share your data with blockchain analysis and are government honeypots. If you want to coinjoin don't use Wasabi or any other ones based on Wasabi!

It's not possible for governments or blockchain analysis to track you when you use Wasabi.  Your client protects your data from being leaked by using block filters to protect your xpub address and Tor to protect your IP address.

Kruw works for Wasabi and makes profit by lying about Wasabi. Wasabi funds BC analysis and is a government honeypot. Just do a web search, it is easy to confirm this.

Do not use Wasabi EVER.

I'm not lying, anyone can verify for themselves since every line of code in Wasabi is completely open source: https://github.com/zkSnacks/WalletWasabi

[kayirigi]

Yes go see the code that Wasabi pays BC analysis to analyze your coins and decide if they are naughty!

You have this confused - the wallet that analyzes your coins is called "Samourai".  Here is the line of Samourai's code where the user's xpub address (containing the entire financial history of their Bitcoin transactions) is sent to their server: https://github.com/Samourai-Wallet/samourai-wallet-android/blob/c4b9fa7e6f72f1c82ab4757b90dc5a0e979b796d/app/src/main/java/com/samourai/wallet/api/APIFactory.java#L1695

Uh oh! More lies from Wasabi shill and government honeypot promoter!

Code:

Assert.Empty(naughtyCoins); // Empty, so we won't kick out anyone from the CJ round.

Are your coins naughty? Then Wasabi censors you!

Thanks for confirming that it's not a government honeypot because a government honeypot wouldn't censor an address that blockchain analysis companies are trying to track
