But despite the increased volume of illicit remittances, its relative share of total crypto trading volume hit an all-time low in These stats show that the rate of expansion of the crypto sector is outpacing the cybercrime associated with it. At the same time, however, it also shows that security in the industry is catching up with demand. While the share of crime-related transaction volume in the crypto space has declined in , there are still some cases that have taken their toll.

So, let's talk about blockchain technology, shall we? What is it exactly? Why are people excited about it? Who invented it? And what is it used for? Today, in the first of a three-part Rational Exuberance series on blockchains, we'll try to cover the first of these questions. As with so many of our Rational Exuberance subjects, it's necessary to look back before we look forward.
In this case, we really need to look as far back as people's first crude efforts at trading goods and services. For as long as people have engaged in trade, they have recorded their transactions as written records in ledgers. Fear not, we are not going to spend too much time revisiting the trauma of your high school or college accounting classes, but it is essential to connect at least a couple of dots. Simply put I hope , a blockchain is an online record or a digital ledger of transactions.
This digital ledger can record monetary transactions, perhaps the movement of goods between two parties or exchanges of information. Now, with that in mind, let's dive in just a little deeper. If we build on the prior concept, a blockchain is also represented by a perpetually growing set of records that are grouped together in blocks.
Importantly, when all these concepts are wrapped together using advanced computer cryptography, we arrive at the essence of blockchain technology. Not surprisingly, then, that's where we get the crypto in cryptocurrency. One of the most important blockchain concepts to understand is how those infinite amounts of records are kept.
Well, blockchains use what is called a distributed ledger system, or DLT. Ledger—there's that word again. Stay with me, I promise this will all be over soon. In a distributed ledger, a record of every single transaction in the blockchain is kept in multiple places concurrently. Anytime a transaction takes place or something is changed in the blockchain, everyone in the entire network is alerted and has to agree or digitally sign off. This attribute is extremely important because it makes it virtually impossible to hack or change the records as this would require changing every single record at precisely the same time.
While this is mathematically possible, most computers would crash trying to calculate the odds of it happening, let alone succeed in such an attempt! To summarize, a blockchain is an online digital record of transactions that is backed by the computational power of modern cryptography. That's it for now, but be sure to look for part two of our Rational Exuberance look at blockchains.

Cybersecurity 101: Protect your privacy from hackers, spies, and the government
This is about to eat my weekend, I think! I'm certain I'm far from alone in that set, but the way the world's going means that we with the generalised technical know-how have a moral impetus to bring the rest of the world up to speed with the whys and wherefores.

Crypto 101 in 2021
Wallet hygiene is the top priority when getting into cryptocurrency and NFTs. This is important because there are many bad actors out there who are looking to hack or steal your digital assets away from you. The main thing to note is that for digital wallets such as Metamask and Rainbow, the web app itself does not hold your assets, it only connects to your wallet using a seed phrase or the private key. Hence it is important to know that Metamask is not your wallet , your wallet is your seed phrase and you should never under any circumstance share this phrase with anyone. Here are some tips, tricks, and general habits to take your wallet security protocol to a whole new level and provide the best possible protection to your digital assets residing on your digital wallet. A post shared by Chain Debrief chaindebrief. When creating a wallet for the first time, make sure you write your seed phrase in a physical form, and never store your seed in a digital format. Make sure you wrote your seed phrase down correctly, and even perform a wallet recovery exercise just to make sure you got the right words. Reset the wallet and try importing your wallet again. You can go as far as splitting the seed in two and store each part in different places e.

Before we start, we need to get some jargon out of the way. Read these, and take in as much as you can. We'll expand on some of them later in the room. Plaintext - Data before encryption or hashing, often text but not always as it could be a photograph or other file instead. Encoding - This is NOT a form of encryption, just a form of data representation like base64 or hexadecimal.
Crypto Week: Understanding Crypto 101
Privacy used to be considered a concept generally respected in many countries with a few changes to rules and regulations here and there often made only in the name of the common good. China's Great Firewall , the UK's Snooper's Charter , the US' mass surveillance and bulk data collection -- compliments of the National Security Agency NSA and Edward Snowden 's whistleblowing -- Russia's insidious election meddling , and countless censorship and communication blackout schemes across the Middle East are all contributing to a global surveillance state in which privacy is a luxury of the few and not a right of the many. As surveillance becomes a common factor of our daily lives , privacy is in danger of no longer being considered an intrinsic right -- and it seems we, too, are adopting our own personal forms of online digital stalking and spying. Everything from our web browsing to mobile devices and the Internet of Things IoT products installed in our homes has the potential to erode our privacy and personal security, and you cannot depend on vendors or ever-changing surveillance rules to keep them intact. Having "nothing to hide" doesn't cut it anymore.
