Why Bitcoin is Not Truly Anonymous

Published

on

The notion that Bitcoin is completely anonymous is a widespread one. It is also incorrect even though transactions involving Bitcoin do not involve the transmission of personal information. It is possible for Bitcoin owners to protect their identity to a certain extent, but not completely. An individual can spend Bitcoin without using their name but their transactions can be connected to the addresses whereby they receive Bitcoins. If those addresses are ever tied to their personal identity, all the transactions associated with them will be tied to their identity as well.

It is widely recommended that Bitcoin owners use a new address for each transaction. While this method does help with anonymity, it is flawed. For a better understanding of why Bitcoin cannot be truly anonymous, it is important to know how the cryptocurrency works.

Bitcoin Overview

Each Bitcoin transaction involves inputs and outputs with inputs being the addresses from which Bitcoin is sent. Each of the addresses has a private key and the Bitcoin can only be transferred using the private key from the address. The outputs are the addresses that receive the Bitcoin. Usually, a transaction requires Bitcoin to be moved from one or more inputs to one or more outputs.

Most transactions involve the merging several smaller inputs and outputs. If an individual controls two inputs of one Bitcoin each and they want to buy an item for 1.5 Bitcoin, then those inputs will be merged to make up one transaction. The transaction will also involve multiple outputs since a change address will be necessary. In the above example, the extra 0.5 Bitcoin will be sent to the buyer’s change address.

Ways in Which Bitcoin Anonymity Can be Compromised

  • Connecting Nodes

The Bitcoin peer-to-peer network is not completely secure. It may be possible for attackers to connect multiple nodes and thus discover the origin of a transaction.

  • Using Personal Identity

If a Bitcoin owner uses their personal identity in a Bitcoin transaction, this can also result in a loss of anonymity. For example, a delivery address for something ordered in an online store could connect the buyer’s name and home address to their Bitcoin. If any of the input addresses in the aforementioned Bitcoin transaction are tied to the buyer’s identity, all of the other addresses will be as well.

  • The Transaction Ledger

Bitcoin transactions are open to all, which means that addresses can be traced. This allows for a group of different Bitcoin addresses to be tied to a particular user. If just one address is tied to an individual’s identity then the others in that group can also be tied to their identity.

 How to Enhance Bitcoin Anonymity

  • Use More than One Wallet

Having multiple wallets can be compared to having several identities. There is a software that Bitcoin owners can use to control several wallets from the same interface (we will come back to that in a later guide).

  • Use One of the Mixing Services

Mixing services blend users’ Bitcoins together. They send them out randomly to make it impossible to figure out the connections between inputs and outputs. While this works, it also requires Bitcoin owners to place a significant amount of trust in the mixing service. There is nothing to stop them from recording the transactions or absconding with all the Bitcoin.

  • Use Online Wallets

Since these services store all the Bitcoin that has been entrusted to them together, it is possible to hide the original owners. This can only work if the wallet service is active. There is also a risk for losing the Bitcoins if the service shuts down or gets hacked.

As Bitcoin evolves, it is expected that there will be upgrades to improve anonymity. These upgrades include ways to keep addresses from being connected during a transaction. Researchers are also working on methods of combining random transactions as a means of enhancing privacy.

What’s Behind Cardano’s Rising Popularity in South Korea?

Published

on

Cardano, better known as ADA in South Korea, pronounced as “aeda” in the local market, is growing at an exponential rate due to UpBit.

// -- Discuss and ask questions in our community on Workplace.

UpBit, South Korea’s second largest cryptocurrency exchange behind Bithumb, is operated by Dunamu, a subsidiary company of Kakao, the operating company of KakaoTalk and KakaoPay. The two mobile applications, KakaoTalk and KakaoPay, have a market penetration rate of over 90 percent in their respective markets–financial technology (fintech) and messaging.

Although UpBit remains as the only cryptocurrency exchange that has integrated Cardano within the local South Korean cryptocurrency exchange market as of date, the popularity of Cardano on UpBit is increasing rapidly. According to CoinMarketCap, 75 percent of Cardano’s daily trading volume is processed in South Korea, by UpBit.

Within its debut month, more than 3 million South Korean users signed up to use KakaoPay, the country’s most widely utilized fintech app. KakaoPay operates as a mobile bank, allowing users to send and receive money, obtain loans, and conduct financial activities. KakaoPay supports UpBit because a subsidiary company of Kakao in Dunamu operates UpBit.

Given that Cardano is one of the most popular cryptocurrencies on UpBit in terms of daily trading volume, naturally, as general consumers in the traditional finance market using KakaoTalk and KakaoPay move to the cryptocurrency market, the first few cryptocurrencies they are introduced to are bitcoin, Ethereum, and Cardano.

Cardano is also receiving significantly more mainstream and local media coverage than other alternative cryptocurrencies, specifically because the South Korean media has portrayed Cardano as a direct competition to Ethereum. Because Cardano is a smart contracts protocol, it is structurally similar to Ethereum.

The two key differences between Cardano and Ethereum are that Cardano uses a proof-of-stake (PoS) consensus algorithm and it also has two layers that are used for smart contracts processing and payment settlement.

In South Korea, cryptocurrency mania has swept across most major industries. 5 out of 10 people on the streets, in subways, buses, and cafes talk about bitcoin, cryptocurrency, and blockchain technology on a regular basis. As such, the majority of investors are more technical than other regions.

Most investors of Ethereum in South Korea understand that the Ethereum Foundation and its open-source development team has been planning a PoS update via Casper. When Cardano debuted with a PoS protocol, it led South Korean investors to believe Cardano is a more innovative platform and has a technical edge over Ethereum.

January 31

For cryptocurrencies with strong followers in the South Korean market, January 31 is an important date to keep track. On January 31, local cryptocurrency exchanges are expected to open account registrations to new users and six major local banks are set to provide banking services to cryptocurrency exchanges.

Consequently, on January 31, it is likely that a massive amount of Korean won will flow into the local cryptocurrency exchange market. The recent cryptocurrency exchange ban fiasco, which turned out to be false, further increased the presence and popularity of cryptocurrencies in South Korea.

Cryptocurrencies like Cardano, EOS, Qtum, and Ethereum that have strong bases in South Korea will likely increase in value throughout late January and early February.

Fidelity Investments is Mining Cryptocurrency

Published

on

Fidelity Investments is a multi-billion dollar brokerage  that just so happens to be mining cryptocurrency. In fact, it has been at it for three years, using its own computers to harvest bitcoin and Ethereum.

// -- Discuss and ask questions in our community on Workplace.

Profitable Experiment

CEO Abby Johnson recently told Fortune that its U.S.-based mining operation is “making a lot of money.” This comes despite running a relatively modest operation.

Hadley Stern, Senior VP of Fidelity Labs, described his company’s venture as an “experiment.”

The real reason we began mining, and still do, is to learn how the network works, how consensus works, how difficulty levels work,” he said in reference to the mining process.

The key to profitability has been the dramatic rise in cryptocurrency over the past year. Bitcoin and Ethereum are the world’s No. 1 and 2 cryptocurrencies by market capitalization, and no-one else comes close.

Well Ahead of the Pack

The fact that Fidelity has been at this for three years speaks volumes about the company. Other, much bigger players are still dipping their toes in the market, but are unsure about how to proceed. Goldman Sachs is reportedly on the fence about starting a cryptocurrency trading operation, while J.P. Morgan has already begun handling customer orders for bitcoin-based instruments.

Fidelity is doing a lot more than just mining tokens. Earlier this year, it reached an agreement with Coinbase to let customers view cryptocurrency prices alongside other assets on their Fidelity homepage.

Coinbase is the world’s most funded cryptocurrency exchange with more than 7.4 million users.

Cryptocurrency Prices

The cryptocurrency market ended the week on a firm note, with bitcoin (BTC/USD) reaching a session high of $4,425.00. At press time, the index was up 1.6% at $4,368.

Ether is also trading higher against the dollar, with the ETH/USD rallying more than 3% to $305.

Ripple (XRP) lost momentum on Friday, but still managed a weekly gain of 21%.

Chinese Government Eyeing Fresh Bitcoin Legislation?

Published

on

The Chinese government could roll out fresh cryptocurrency regulation in the coming months permitting licensed brokers to operate, based on recent information from Xinhua.

// -- Discuss and ask questions in our community on Workplace.

The state-owned news publication recently revealed that the government is mostly concerned with stamping out illegal activity involving bitcoin and other cryptos. Government authorities could be planning to regulate the market by creating a licensing program with strict Know Your Customer (KYC) and Anti-Money Laundering (AML) systems.

The Case for AML

The need for KYC/AML protocols has long been raised by cryptocurrency proponents, especially in reference to initial coin offerings (ICOs). In response, the blockchain community has come together to create the Simple Agreement for Future Tokens (SAFT). The SAFT is both an instrument and open-source framework for token sales that vets accredited investors.

SAFT activity is quickly gaining traction, with the likes of Gizer recently issuing a presale of its ICO through SAFTLaunch.

SAFT was officially created by Protocol Labs in close collaboration with AngelList and Cooley.

China’s Stance Looms Large for Cryptocurrency Market

Although digital assets have recovered from the China-induced flash crash of September, favorable regulations on the mainland could mean big business for bitcoin exchanges. Prior to the ban on ICOs and bitcoin brokers, Chinese investors were responsible for a quarter of all BTC trades.

According to Xinhua, China is likely to pursue a licensing program similar to Japan, a country that recently approved 11 cryptocurrency exchanges. CnLedger, a leading source of cryptocurrency news in China, recently had this to say:

“Xinhua News, official press agency of CN: Virtual currencies have become the top choices of underground economies. We shall adopt ‘0-tolerance policies’ towards crimes hidden underneath and take measures such as record-keeping, licensing, AML processes, real-name, limiting large transactions.”

Is China’s cryptocurrency ban temporary? It certainly looks that way. Regulators must already know that the ban hasn’t stopped mainland investors from buying cryptocurrencies next door in Hong Kong or Singapore. A saner approach to an all-out blanket ban is a tighter regulatory framework that will stamp out money laundering and other underground activities.
