Bitcoin ethereum centralized
Vitalik Buterin created ethereum, the technology behind the cryptocurrency ether, after World of Warcraft developers weakened his prized character. According to his about. His bio circulated on social media over the weekend after a Google developer noticed it and tweeted out Buterin's World of Warcraft back story, Vox Media's Polygon first reported. In , after quitting the game, Buterin became interested in bitcoin and co-founded Bitcoin Magazine, he told Insider previously. Eventually, Buterin, who was born in Russia and grew up in Canada, dropped out of school at the University of Waterloo to focus on crypto full-time, according to his bio.

Cryptocurrency Might be a Path to Authoritarianism
This blog is a preview of our Crypto Crime Report. Cybercriminals dealing in cryptocurrency share one common goal: Move their ill-gotten funds to a service where they can be kept safe from the authorities and eventually converted to cash.
Money laundering activity in cryptocurrency is also heavily concentrated. We saw an example of this last year, when the U. However, we know anecdotally this is happening, and later in this section provide a case study showing an example of it.
For comparison, money laundering accounted for just 0. The biggest difference between fiat and cryptocurrency-based money laundering is that, due to the inherent transparency of blockchains, we can more easily trace how criminals move cryptocurrency between wallets and services in their efforts to convert their funds into cash.
What kinds of cryptocurrency services do criminals rely on for this? Where did cybercriminals send funds instead?
DeFi protocols make up much of the difference. Mining pools, high-risk exchanges, and mixers also saw substantial increases in value received from illicit addresses as well. We also see patterns in which types of services different types of cybercriminals use to launder cryptocurrency. One thing that stands out is the difference in laundering strategies between the two highest-grossing forms of cryptocurrency-based crime in Theft and scamming.
This may be related to the fact that more cryptocurrency was stolen from DeFi protocols than any other type of platform last year. We also see a substantial amount of mixer usage in the laundering of stolen funds. Scammers, on the other hand, send the majority of their funds to addresses at centralized exchanges. Hacking cryptocurrency platforms to steal funds takes more technical expertise than carrying out most scams we observe, so it makes sense that those cybercriminals would employ a more advanced money laundering strategy.
As stated above, some criminals use cryptocurrency to launder funds from crimes that happen offline, and there are many criminal addresses in use that have yet to be identified.
However, we can account for some of these more obscured instances of money laundering by looking for transaction patterns suggesting that users were trying to avoid compliance screens. Exchanges using Chainalysis would be able to see that these funds are coming from illicit addresses regardless of transfer size.
But more generally, compliance teams should consider treating users who consistently send or receive transactions of that size with extra scrutiny. We can see how that concentration has changed over time below. With fewer services used in , money laundering concentration initially appears to have increased slightly.
However, money laundering activity is better viewed at the deposit address level rather than the service level. Over-the-counter OTC brokers, for example, often function as nested services with addresses hosted by large exchanges. In the graph below, we look at all service deposit addresses that received any illicit funds in , broken down by the range of illicit funds received. How to read this graph: This graph shows service deposit addresses bucketed by how much total illicit cryptocurrency value each address received individually in Each blue bar represents the number of deposit addresses in the bucket, while each grey bar represents the total illicit cryptocurrency value received by all deposit addresses in the bucket.
Law enforcement action could be one possible reason money laundering activity became less concentrated. We also see differing levels of concentration in money laundering depending on the asset. We also see differences in the level of money laundering concentration for different types of cybercriminals. What stands out most is how much less concentrated money laundering activity is for scammers and darknet market vendors and administrators compared to other crime categories.
This may reflect the fact that the criminal activity for those categories is itself less concentrated. As we discussed above, usage of DeFi protocols for money laundering skyrocketed in The Spartan Protocol hack provides a good example of what this activity looks like.
The hacker then converted much of those funds into anyETH and anyBTC, which are Ethereum and Bitcoin composites respectively built on separate blockchains from those assets. Some of that anyBTC was then swapped for Bitcoin, thereby moving to the Bitcoin blockchain, which brings us to the transactions seen on the Chainalysis Reactor graph below. Using two DeFi protocols that specialize in cross-chain transactions, the hacker chain hopped to the Ethereum blockchain, converting funds into Ethereum and renBTC.
Finally, the hacker sent those funds to Tornado Cash, a mixer for the Ethereum blockchain. While most of these transactions took place in the days immediately following the hack in early May, several took place months later, with the hacker continuing to launder funds well into October.
This would be less likely to happen with centralized services, which unlike DeFi protocols typically ask customers for KYC information upon signup and have more ability as custodial platforms to freeze funds from suspicious sources.
The Spartan Protocol hack is a great example not just of why DeFi holds appeal as a money laundering mechanism, but also of how complex investigations can become when cybercriminals use DeFi — especially chain hopping protocols. Law enforcement must become proficient in analyzing DeFi transactions in order to crack cases like that of the Spartan Protocol hack, but the teams behind DeFi protocols must also work to prevent their products from being abused by cybercriminals.
One way they can do that is by screening the wallets interacting with their smart contracts for prior transactions with known illicit addresses. If you work in DeFi, contact us here to learn more about automated wallet screening. The only way someone could know the origins of those funds would be if they were already investigating the criminals in question, and we know anecdotally that at least some criminals are doing this. The scheme was simple: The group supplied drugs across northern England and distributed them to street-level dealers, who would then sell them for cash which was later delivered back to the crime group.
A courier would then collect the cash and deliver it to a broker who would arrange for the funds to be converted into bitcoin. The Bitcoin network is essentially used as a value transfer system, and further analysis showed that the funds were ultimately sent to an OTC service nested at a popular cryptocurrency exchange. Police arrested the suspect for money laundering and seized two mobile phones.
A subsequent digital forensic examination of these devices showed various WhatsApp and Telegram messages detailing the plan, complete with Bitcoin addresses and screenshots of transaction hashes.
With this information, the officers were able to utilize blockchain analysis to see the flow of funds. Using Chainalysis Reactor, we can see the activity discussed in the message screenshot above:.
This represents a relatively low fee in comparison to more traditional money laundering typologies, suggesting that Bitcoin-based laundering could become increasingly attractive to traditional criminals. The funds are then sent to an intermediary wallet before being deposited to an OTC service nested at a popular cryptocurrency exchange. The case shows how important it is for all criminal investigators — not just those tasked with cybercrime cases — to understand cryptocurrency and blockchain analysis.
It also serves as an example of how blockchain analysis can supplement more established investigative techniques law enforcement is already well-versed in. This material is for informational purposes only, and is not intended to provide legal, tax, financial, or investment advice.

Bitcoin’s Decentralized Decision Structure
One of the main draws of cryptocurrencies such as Bitcoin is that they are decentralized. As you will likely know, Bitcoin can be traded like a stock or share, and crypto exchanges are acting increasingly as traditional banks, so is crypto becoming centralized? Some signs are arguably pointing towards that. However, as this is going on, the world of decentralized finance DeFi is flourishing. So, what is the state of crypto - is it in risk of becoming centralized, or is crypto truly decentralized?

101 Smart Contracts and Decentralized Apps in Ethereum
We probably started hearing about Blockchain almost a decade ago when someone under the pseudonym of Satoshi Nakamoto released the first Bitcoin reference implementation. If you ever wonder who Satoshi is, you are not alone, and I am pretty confident it's a secret; nobody will reveal it in the years to come. Bitcoin not only introduced a digital currency as we know it today but also made popular the theory behind one of the most important inventions in the last decade, Blockchain technology. But what is Blockchain exactly? We will try to give a definition leaving all the fuzzwords behind.
BTC vs. ETH and other crypto trends for 2022
At any particular moment, thousands of computers around the world are humming away, crunching complex math problems that create and sustain bitcoin. This network gives bitcoin its appeal: decentralized, always on and easily tradeable. But it also means the network is constantly using energy — a sticking point for many of the cryptocurrency's skeptics and critics. And it's not just a bitcoin problem. Other cryptocurrencies and blockchains including Ethereum have similar challenges.

Cryptocurrencies have now become commonplace in the online world. Although most of the media attention is focused on Bitcoin, Litecoin, Dogecoin, or other decentralised payment systems, the true revolution is happening at a much deeper level, one that does not involve only money. On 22 July , a new cryptocurrency has become available on the market. After many months of preparation, Ethereum finally launched the pre-sale of its very own cryptocurrency - Ether - raising over But what distinguishes Ethereum from other more traditional cryptocurrencies is that it provides a platform for the deployment of decentralised applications which have the potential to disrupt some of the most powerful organisations in advanced societies: those who instantiate financial and governmental institutions. An institution refers to any social structure in charge of governing the behaviour of individuals within a given community - such as law, money, religion, education, etc Durkheim,

Ethereum is a public blockchain platform that allows developers to build and deploy decentralized applications. Ethereum runs smart contracts, which allow a higher level of protection from downtime, censorship, fraud or third party interference. Ether is a tradeable cryptocurrency, used by application developers to fuel the Ethereum network. The bitcoin blockchain is used to track ownership of digital currency, while the Ethereum blockchain focuses on running the programming code of any decentralized application. As opposed to mining for bitcoin, in the Ethereum blockchain, miners work to earn Ether. Ethereum enables developers to build and deploy decentralized applications.
