Transactions — Bitcoin

Liberating the Nepalese Economy one Satoshi at a time.

Welcome to BitcoinNepal. This subreddit is dedicated to information/transaction of BTC in Nepal or between fellow daju/bhai/didi/bainis. BTC relies on a trust-no-one system so please keep that in mind. However, our social structure relies on trust-a-lot so it will be interesting to see how we conduct business between ourselves.

How Monero, ZCash, and Celare Will Enable True Privacy

How Monero, ZCash, and Celare Will Enable True Privacy

When cryptocurrencies were first introduced, their unique anonymity and privacy features attract plenty of people. Even Satoshi Nakamoto, the creator of bitcoin, is shrouded in mystery as no one knows the true identity of the person or group. However, privacy issues for cryptocurrency users have continued to worsen.
In many ways, bitcoin transactions are not anonymous as the open ledger offers perhaps the most transparent payment history of any financial system to date. While there are no official names directly attached to crypto wallets, there are still many steps users must take to ensure their privacy.
In response, a different class of cryptocurrencies was introduced: privacy coins. Let’s dig a little deeper into what makes a “privacy coin,” how they’re different from bitcoin and other cryptocurrencies, and learn a bit about the significant privacy coins on the market today.
https://preview.redd.it/soqg4dmyj4u41.jpg?width=1200&format=pjpg&auto=webp&s=f1600f0db83552d10c892e64ebcda9d17f6ff8be
What is a Privacy Coin?
A “privacy coin” is a type of cryptocurrency that ensures the privacy and anonymity of its users. In the simplest terms, privacy coins rely on the same blockchain technology as cryptocurrencies like bitcoin, but go a step beyond in how they handle information about transactions and obfuscate some info.
For example, bitcoin transactions are all recorded on an open public ledger showing that X address sent Y address with the amount of BTC. While there are no names attached to wallet addresses, it’s not incredibly challenging to link addresses with people by the powers that be, especially when it comes to liquidating holdings with a licensed exchange.
Privacy coins conceal information about senders and receivers during transactions through a variety of methods. The vital part of knowing is that, unlike bitcoin transactions, privacy coins hide information about wallet activity or at least offer the feature to users.
Government Response to privacy coin
Given the nature of privacy-driven cryptocurrencies, it is not surprising that they have gained the attention of many government agencies. More than 80% of the 66 world’s central Banks are already studying digital currencies, according to the Bank for International Settlements(BIS) survey.
https://preview.redd.it/eunqox21k4u41.jpg?width=1600&format=pjpg&auto=webp&s=6f44c686d911f3750bee360f3f7a13846fa6e96b
The federal reserve is also conducting research and experiments on technologies related to electronic payments and digital currencies and has begun studying the feasibility of digital currency issuance.
Brainard said, “Current research issues include the following aspects: the fed digital currency will make the payment system becomes more simple and safe, the digital currency will affect the financial stability, how to solve the problem of privacy and fraud, etc.
According to recent domestic reports, the central bank digital currency (DCEP) is also internally testing application scenarios in areas such as payments. The central bank is leading the digital currency, and Banks are testing it internally on landing scenarios, among others. Some are already using it among their employees to pay party dues and other payment scenarios.
Based on the active research on blockchain technology and digital currency by various governments, it is reasonable to believe that compared with the existing digital currency system, anonymous currency with a higher level of privacy protection will also have more development space.
Now let’s look at some of the biggest names in the space and how they make privacy happen.

The Big Three Privacy Coin
https://preview.redd.it/f1d8k474k4u41.jpg?width=720&format=pjpg&auto=webp&s=4932abfab694c4376d47d07c46f9e2616849d79c

Monero(XMR)

Perhaps one of the most well-known privacy coins, Monero, actually started as a fork from Bytecoin in 2014. With Monero, the addresses of both the sender and receiver are kept private on the ledger, meaning there’s also no way to see the value of a user’s wallet. The Monero network protects user privacy by utilizing stealth addresses (a one-time address created by the sender for each transaction), ring signatures (a method that uses multiple signatures as decoys to obfuscate address of the sender), and Ring Confidential Transactions, also known as “RingCT” (an improved version of ring signatures that hides the amount of XMR used in a transaction).
Monero further increases the privacy of transactions via a unique splitting mechanism. Each full transaction is divided into different amounts and sent as a subset of separate, smaller transactions adding up to the initial value. For example, if you wanted to send 1,000 XMR, this amount would get split into a variety of separate amounts, say 200 XMR +150 XMR + 325 XMR + 275 XMR + 50 XMR, each of which getting its one-time address.
Next, with the help of the ring signature, each separate transaction gets combined with a variety of decoy transactions, thereby rendering the transaction nearly impossible to trace.
Furthermore, Monero also features spend keys and view keys. The alphanumeric spend key allows an authorized user to conduct transactions on behalf of the account, while the view key enables users to look at a specific account’s holdings. It comes in handy when reporting holdings for tax purposes, or auditing a company’s financial reserves.

Zcash(ZEC)

Zcash was created as an alternative to Bitcoin and claims to boast enhanced privacy and security. Unlike Monero, private transactions are not required when using Zcash. Instead, users have the option to use the enhanced privacy feature to obfuscate transaction details and use either a transparent wallet address or a “shielded address” to keep transactions private. To accomplish this, Zcash utilizes zk-SNARK, short for “Zero-Knowledge Succinct Non-Interactive Argument of Knowledge” and the zero-knowledge security layer (ZSL).
These two security mechanisms permit existing blockchain applications to support semi-transparent transactions, effectively allowing users to display a small sub-set of data about any transaction. This is used in everyday applications to verify that payments were executed at specific times. However, it masks critical user information in the process, including the sum of the transaction as well as the personal information of both transacting parties.
Zcash has also entered into partnerships with several leading financial institutions and blockchain companies, including JP Morgan, Parity, and StarkWare.

Celare

Unlike Monero, Dash is not driven solely by privacy, but by providing users with privacy protection for transactions and cross-chain solutions. Since most anonymous coins are private but not widely applicable and cannot be cross-chain exchanged, the Celare Co-Founders’ Committee has been researching cross-chain technology since 2018 and has finally developed a cross-chain solution to the security and privacy of chain assets — Celare.
Celare achieves zero-knowledge proof by selecting the BLS12–381 curve, and indeed implements a Blockchain system with privacy protection for Turing-complete smart contracts.
In principle, the advantage of it is that it can share the security and cross-chain operation of Polkadot, and independently develop its in-chain system. Therefore, Celare’s design will be compatible with Polkadot, and it also has its unique algorithms and functions.
https://preview.redd.it/bt8gbpnek4u41.png?width=2300&format=png&auto=webp&s=dddc4c4384d5fcf39f5d755e30e902410b82aa0a
Celare supports Turing’s comprehensive smart contracts, cross-chain asset transactions, and various related privacy protections to support the expansion of different economic ecosystems.
Starting with the Celare system, the issuance, and control of anonymous assets will no longer be exclusive to a few geeks who have in-depth knowledge of cryptography. Ordinary developers can issue their assets on the Celare chain as long as they have relevant business needs. Anonymous assets, establish their privacy ecology, which significantly expands the scope of application of Blockchain privacy protection technologies.
Compared with the existing Blockchain privacy protection technology, Celare is a rising star in anonymous currency with inestimable development potential. It can not only achieve a collaborative and efficient cross-chain function but also guarantee the security and privacy of cross-chain assets.
Although Monero and Zcash have been implemented earlier, there are still many limitations in practical application.
Celare not only has the same privacy and anonymity technology as Monero but also incorporates the zero-knowledge proof and other technical and theoretical support adopted by Zcash. On this basis, Celare innovatively adds a powerful cross-chain function.
In the future, there will be more stack extension applications in Celare ecology, such as anonymous wallets, anonymous asset exchange, anonymous chat tools with OTC function, which are likely to surpass the former two.
Since the development of Blockchain technology, there are many imperfections. However, it can be seen that all individual teams and communities that have faith in the Blockchain are actively promoting the healthy development of Blockchain ecology.
We have also noticed that the update and iteration speed of the blockchain era is much faster than we imagined. We hope that anonymous currency will have more broad development prospects in the future.

The real issue with Facebook-coin and how it can backfire on Facebook. (all without the opinion of sensationalist news articles).

Alright, so here is the real issue with Facebook coin, let's take Zimbabwe as an example. Bitcoin transactions were made illegal in Zimbabwe for being a more reliable medium of transfer than their present currency or basket of currencies they went through over the years. Zimbabwe's present currency is a sort of stock or bond that is binded 1:1 to the USD if I recall correctly.
From my perspective, based on what we've read in the whitepaper megathread, we can infer that this is supposed to be some middle-man financial service that is immediately more accessible than a bank, but less hassle than a bank. If you get caught sending Edward Snowden Facebook-coin, your account will be locked at the request of the U.S. government.
It is permissioned. That means if you live in Zimbabwe and Facebook doesn't like your transaction history (even though you're just buying simple items / services (food, hygiene products, hair cuts, pedicures etc.) without harming anyone), your transactions can be blocked. Why? The government of Zimbabwe could get in to a scuff with Facebook about taxation / profits to the Zimbabwe government and threaten to block Facebook in their country if Facebook-coin is not a government-compliant service. However, Facebook should be thinking ahead to scenarios like this and trying to be as compliant as possible.
However, one aspect that countries like Zimbabwe would probably appreciate about Facebook-coin is the ability to bring capital from abroad in to their own country.
Right now Facebook is penny-pinching all of the companies that are using their platform to advertise (which is their main revenue stream). I know because I work for a company that engages in Facebook ad campaigns. Media and posts that could get tens of thousands of impressions for free in 2017 are now only getting a few hundred at maximum.
TL;DR If Facebook-coin flops due to government incompliance, Facebook's stock value will plummet, which I am perfectly fine with.

Ryan X Charles has epiphany on importance of malleability for Bitcoin/Metanet.

Joe Weisenthal’s latest Twitter rant on Bitcoin is a perfect example why you can’t fairly compare Bitcoin transactions to USD transactions.... the IRS treats USD and Bitcoin completely different. Too bad Joe has the platform to spout this non-sense

If the IRS treated USD and Bitcoin (ie gave people a real choice) then you can be sure our community would transact a lot more with Bitcoin or Lightning

Creating transactions is something most Bitcoin applications do. This section describes how to use Bitcoin Core’s RPC interface to create transactions with various attributes.. Your applications may use something besides Bitcoin Core to create transactions, but in any system, you will need to provide the same kinds of data to create transactions with the same ... However, in bitcoin, the history of each and every single bitcoin transaction is taken note of. Ok, so now let’s do a deep dive into how a bitcoin transaction between Alice and Bob takes place. There are two sides to a transaction, the Input, and the Output. This entire Transaction will have a name that we will figure out in the end. For now, let’s look at the dynamics. Transaction Input ... An transaction is a transfer of Bitcoin value that is broadcast to the network and collected into blocks. A transaction typically references previous transaction outputs as new transaction inputs and dedicates all input Bitcoin values to new outputs. Transactions are not encrypted, so it is possible to browse and view every transaction ever collected into a block. Once transactions are buried ... In our example transaction above, Mark wants to send some BTC to Jessica. To do this, he uses his private key to sign a message with the transaction-specific details.
