What is Bitcoin and the Blockchain?
What is Bitcoin?
Bitcoin is the first decentralised digital currency in the world. It was introduced in 2008 by a pseudo-anonymous developer named Satoshi Nakamoto.
Bitcoin operates on peer-to-peer technology and does not require any bank or a financial institution as an intermediary. Bitcoin can be used to purchase goods and services online, make cheap international money transfers and it is also considered as one of many innovative new ways to invest your money as its price has been increasing substantially as its adoption is growing globally.
What is the Blockchain?
The blockchain is the underlying technology that the cryptocurrency bitcoin is built on. The blockchain is an immutable open-source distributed ledger network that publicly records all bitcoin transactions. The digital ledger can be viewed at Blockchain.info.
The blockchain is upheld and updated by all network participants who utilize their computing power to maintain and secure the bitcoin network in real-time. Hence, if some participants of the bitcoin network fall victim to an attack, the network remains functional as it is a decentralized peer-to-peer network. The bitcoin blockchain participants also verify and process all transactions on the bitcoin network. For this service, these bitcoin network participants receive new bitcoins through what is referred to as mining.
Furthermore, due to its open-source nature, the code for the blockchain can be changed to create new digital currencies but it can also be augmented so that it can be employed for non-financial uses.
For example, new blockchains could be used for transparent voter registration, to record proof of ownership of assets or land and intellectual property or for digital identity verification. The possibilities for the potential uses of the blockchain are almost limitless. That is also one of the primary reasons why there has been such a hype around bitcoin and the blockchain in the tech space.
In Africa, the most popular centralised cryptocurrency exchanges are Ice3X and Luno. However, the majority of bitcoin transactions in Africa occur over the peer-to-peer exchange LocalBitcoins.com.
What Can Bitcoin Do in Africa?
One of bitcoin’s key selling points is its low transaction fee when conducting money transfers regardless of the location of the sender and the recipient. Hence, the biggest case for bitcoin adoption in Africa is for remittance purposes. However, the use of bitcoin as a spending currency could also be very beneficial to the underbanked communities of Africa that often rely on cash-only transactions.
The blockchain, as mentioned above, could be used in all sorts of ways in Africa. Its potential uses range from voter registration to proof of land ownership and even the reduction of corruption. While it will remain to be seen whether the digital currency bitcoin will become a viable everyday spending currency. Its underlying technology, the blockchain, will without the shadow of a doubt make its impact in Africa for the better of its communities.
How Often Is Crypto Really Used In Illegal Activity?
Statistics, examples, and ways to legally use cryptocurrency
October 1, 2013, was a turbulent day for San Francisco Public Library. A dozen FBI agents pretending to be usual visitors surrounded a man sitting at one of the tables, took his laptop and put a pair of handcuffs on his hands. That man was Ross Ulbricht, founder of Silk Road – the largest darknet marketplace for drug dealers, killers, and other criminals. The seizure of Ulbricht was supposed to tackle the illegal online trade, but, as the news site DeepDotWeb wrote, the bust was “the best advertising the darknet markets could have hoped for”. The reputation of cryptocurrency also suffers from associations with terrorists, who sometimes use it for their needs. How big is the real scale of the problem? And how many legal ways to use crypto exist? ChangeNOW has dived into the topic – and suggests you an overview of the current state of the problem.
- The drugs trade volume using cryptocurrency is relatively large
- Crypto was a significant reason why a part of drug sales migrated to the web, though stays yet not viable and anonymous enough for dealers (same as for terrorists)
- As efficient use of blockchain technology requires good infrastructure, crypto remains not suitable enough for many terrorist groups
- However, some terrorists are trying to adjust to anonymity threats and hold fundraising in crypto
- Legal ways to use cryptocurrency include dozens and vary from IT services to car rentals
Crypto & Drugs & Rock’n’Roll
The total volume of the online drug market using cryptocurrency is around $1 billion. It is located in the darknet, which provides an attractive, profitable, and mostly secure environment for drug dealers. Cryptocurrency, in turn, allows making payments that are hard to be tracked by authorities. This is how blockchain technology has helped to bring a big part of drug sales online from the streets. And it’s not only about drugs themselves – many legal opioid drugs are illegally sold here, too.
However, cryptocurrency is not always as secure and anonymous as it is thought to be. The information about any transaction ever made stays forever in the blockchain, which makes the system way more transparent than cash payments. This is a significant limitation for using crypto in illegal purposes.
According to the University of Technology Sydney, about 46% of criminal activity of each year is connected to Bitcoin. As for the drug sale itself, trade volumes in crypto keep rising, but the percent of Bitcoin drug transactions out of all transactions goes down. This means Bitcoin is more frequently used for legitimate purposes.
What cryptocurrency is used for drug sales most often? Surprisingly, privacy coins such as Monero are used only for 4% of transactions. Due to its pioneer position, Bitcoin is used in 76% of all deals despite all its anonymity risks.
The main problem for drug dealers using crypto is to turn their income into cash. This move remains complicated and insecure. Most cryptocurrency exchanges have instruments to define whether a transaction is coming from a suspicious source like the darknet. The rise of Monero use in the online drug market will hinder such tracking. However, for the reasons listed above, crypto is unlikely to completely replace regular cash in drug sales in the foreseeable future.
The views on how much cryptocurrency is used and will be used by terrorists vary widely. While some claim that terrorists have no infrastructure to use it and the methods are not secure enough, others argue that they are learning fast and adjust to crypto rapidly. Let’s see what both sides say.
Not actively using, unclear future
Lack of appropriate infrastructure, inability to use crypto. Most terrorist groups settle in the Middle East region, especially on its remote and war-torn territories. The vast majority of roads and technological infrastructure have been destroyed. In such circumstances, cash remains the most common and convenient way to pay and fundraise. Imagine a gun seller in a Syrian village – does it look like he has a tool to accept Monero?
Anonymity threats. Given the relative transparency of blockchain mentioned above, crypto might remain too unsafe for terrorists. Miners can see any potential terrorist money exchange while checking transactions, and it’s not too hard to see who sends them money. It can change with the rising use rate of privacy coins, but the ability to spend such money remains questionable.
Increased attention to crypto by the authorities. As the number of transactions keeps rising, more regulatory bodies’ attention gets focused on cryptocurrency, which apparently makes terrorists nervous and cautious.
Problems of specific currencies. While top cryptocurrencies like Bitcoin receive much regulatory attention, others remain marginal and unreliable because of a lack of support. Conflicts and uncertainty lower the trust to such cryptocurrencies – yes, even terrorists’ trust.
Using actively now, increasingly in the future
Terrorists seem to be rapidly learning to escape from tracking in blockchain. Several years ago it was easy to find any address or transaction made for a terrorists’ fundraiser. Today they use well organized and finely designed websites, where detailed video tutorials show how to donate money anonymously. Unique Bitcoin addresses and other crypto tricks are used to preserve security. Analysts from intelligence services claim there’s only going to be more such cases. And, of course, privacy coins are a “great opportunity” for terrorists too.
Shift to cryptocurrency is a reaction to economic sanctions. ISIS has lost most of its territory and resources, Hamas has been sanctioned by the West. Having been cut off from all main financial institutes, terrorist groups had to find other pathways for their financial activities – and cryptocurrency appeared to be the best substitute.
There might be difficulties and inconveniences, and the number of terrorists using crypto is yet unknown – but as we can see, digital money in terrorism is reality. Same as in drugs. And this is what cryptocurrency is notorious for, lacking trust among millions of people. The reputation of some of the exchange services only adds to this mistrust – ChangeNOW has carried out a special investigation on how such platforms may cheat their clients. But can you buy anything besides heroin and firearms with your crypto? What about pizza or a concert ticket?
Only Antarctica left
Cryptwerk, a platform monitoring actual use cases of different cryptocurrencies, says there are about 3500 ways to spend Bitcoin and more than 800 for Monero today. They range from music services to car rentals, from buying clothes to hotel booking services, and from sports bets to virtual tours.
Organizations accepting cryptocurrency are located on all continents besides Antarctica (what could be a better place for crypto than a continent without governments and countries though?). Mostly, in the USA and Central Europe. Bitcoin as the largest cryptocurrency is relatively widespread in India and Southeast Asia.
As this is a whole another topic, ChangeNOW will issue a post dedicated to use cases of cryptocurrencies. As it will be more detailed, who knows – maybe you’ll find a pizza right by that you could pay for from your crypto wallet!

3 Reasons to Use a Bitcoin Mixer in 2020
Bitcoin is not as anonymous as people think. Bitcoin transactions are viewable on the network’s public blockchain, which also means that transactions can be linked to real-world identities. As a result, bitcoin is not (yet) fungible and does not protect individuals’ financial sovereignty as much as it should. Fortunately, there is something called a bitcoin mixer that enables bitcoin users to increase their financial privacy.
In this guide, you will learn what bitcoin mixers are and why you should consider using them.
How Anonymous Are Regular Bitcoin Transactions?
Regular bitcoin transactions are not anonymous. Bitcoin addresses are pseudonymous. They do not reveal your identity as a user but can be linked to your identity.
For instance, most exchanges require you to verify your identity with legal identification (ID) documents. In a situation where you withdraw funds from an exchange into your wallet, your identity can be linked to that wallet, and all your linked transactions could be tracked.
Blockchain analysis companies can use information from your linkable transactions to track how many bitcoins you own, what you spend your coins on, and who you transact with. If you are conscious about your privacy, you might need a bitcoin mixer.
What is a Bitcoin Mixer?
A bitcoin mixer allows you to mix your coins with other users. This obscures the ties between your personal identity and bitcoin transactions.
The end goal of a bitcoin mixing service is to create a misleading trail of transactions that makes it difficult to track your transactions. This is achieved by breaking down your bitcoin into smaller parts and then mixing them with coins from other transactions.
Most bitcoin mixers are non-custodial, run on the Tor network, and do not keep records of users after a couple of hours.
Why Do People Use Bitcoin Mixers?
The primary reason for using a bitcoin mixer is to increase transactional privacy. You may not want “the whole world” to be able to see what you are doing with your bitcoin. Through the use of a mixing service, you can achieve that despite Bitcoin’s public blockchain.
Moreover, there are a number of other reasons why you should consider using a bitcoin mixer. They include:
Your Transactions Reveal Personal Finance Information
Every time you send bitcoin to or receive bitcoin from an individual, the other party gains some information about your bitcoin holdings.
For example, if you have ten bitcoin in your wallet and you send two to another person. The individual who received the bitcoin now has access to your bitcoin address, which allows them to check your balance on the blockchain.
In some cases, by analyzing your inputs and outputs, they can predict other addresses you own, giving them more information about your finances and transactions you have done in the past. Mixers can prevent this. The mixer breaks the connection between addresses in your wallet by creating transactions that make it difficult for blockchain analysts to track.
Based on the example above, if you use a coin mixing service to send out the coins, the receiver can still check the blockchain to verify the transaction but will be unable to track your old transactions and find your bitcoin address.
Blockchain Analysis Companies Are Watching
Over the years, blockchain analysis companies have been established to track transactions and monitor the Bitcoin blockchain. These groups have resources to probe deeper into transactions, with some going as far as connecting IP addresses to bitcoin transactions.
Further, cryptocurrency exchange verification is required by regulators to keep an eye on how individuals use their bitcoin. This means that exchanges can still trace your transactions after you have purchased bitcoin.
Bitcoin mixers allow you to detach connections between your initial receiving address and other transactions you make. This can prevent companies from gathering data about you, which it would otherwise share with (or sell to) third parties.
To Prevent Censorship
Money has become a tool used to fund political groups and operations. In authoritarian regimes, where the financial system is highly monitored by the ruling government, critics or opposition groups may opt for bitcoin.
To ensure complete privacy while using bitcoin, such groups will require bitcoin mixing platforms. Without increased transaction privacy, these groups risk losing support in situations where the state begins to target individuals funding them by tracking their transactions on the blockchain.
This allows bitcoin to be used as a tool for freedom of speech and expression.
