When pondering what Jack Dorsey would do after his departure from Twitter, my first thought was focusing on Square and cryptocurrency. Now, a few days later, the company has changed its name to Block.
We built the Square brand for our Seller business, which is where it belongs. Block is a new name, but our purpose of economic empowerment remains the same. No matter how we grow or change, we will continue to build tools to help increase access to the economy.

Vitalik Buterin, co-founder of the Ethereum blockchain, is proposing EIP-4488 as a way to help reduce gas fees.
After highlighting concerns regarding the transaction fees on the Ethereum network, Buterin suggested the new EIP-4488, saying that it would “decrease transaction calldata gas cost, and add a limit of how much total transaction calldata can be in a block.”
In other words, EIP-4488 would limit the total transaction calldata, where data from external calls to functions are stored, before reducing the calldata gas cost to remove the possibility of breaking the network.

Bloomberg reports on a theft involving a Canadian teen stealing US$36.5 million in cryptocurrency from a victim in the U.S.
Police said the victim was targeted through a cell phone scam known as SIM swapping, in which a scammer hijacks a wireless customer’s phone number to intercept two-factor authentication requests and gain access to the victim’s accounts.
The arrest was the result of a joint investigation with the Federal Bureau of Investigation and the U.S. Secret Service Electronic Crimes Task Force, the Hamilton Police Service said in a statement. The investigation was launched last year in March.

The World Economic Article advises companies to integrate blockchain technology, writing about “middleware” such as Chainlink (LINK).
While there remains a general assumption that blockchain technology is still in its early stages, in reality, it is already entering the early phase of majority adoption, especially by the finance industry. Recalling the massive digital transformation propelled by the internet, many forward-thinking enterprises in the finance sector and beyond are already taking important steps to become blockchain-ready.
I think it’s interesting that WEF is talking about blockchain stuff. It’s also good news for companies such as Chainlink, because they make it easy for stuff on a blockchain to interact with stuff off the chain. Disclaimer – LINK is one of the cryptocurrencies I invest in.

A lot of people think that they are completely anonymous when they use Bitcoin, and this gives them a false sense of security. In our research, what we did is that we crawled social media, like there’s popular forum for Bitcoin users called Bitcointalk.org, and we crawled Twitter as well for Bitcoin addresses that users attributed to themselves. In some forums, people share their Bitcoin addressees along with their profile information. So, now you have the public profile information, which includes usernames, emails, age, gender, city.

Following a collaboration with Coinstar, Walmart customers can now make use of 200 Bitcoin ATMs in the retail giant’s pilot program.
The process of buying Bitcoin through these machines is straightforward but relatively costly. Shoppers will insert banknotes into the ATM, which will then issue a voucher carrying a redemption code. The voucher can only be redeemed after the completion of the Know-Your-Customer process. According to the Coinstar FAQ page, “Each purchase carries a transaction fee of 4% and a cash exchange fee of 7%.”
Translation: If you really want to buy Bitcoin with cash, this method may be a good option for you. Otherwise you can buy cryptocurrencies through exchanges. Privacy downside: Many of these exchanges are required to use a Know Your Customer (KYC) process. Upload your photo, driver’s license, and fill out other personal information.

Laws drafted in the 1930s to facilitate effective oversight of our financial system could not contemplate this technological revolution. Elements of those laws do not have room for the transformational potential that digital assets and crypto innovation make possible. They do not accommodate the efficiency, seamlessness, and transparency of digital asset markets, and thus risk serving as an unintended barrier to current innovations in the digital asset economy.
OpenSea, one of the biggest marketplaces for NFTs, has security flaws that leave user wallets open to attack.
The researchers stated that the vulnerability allowed hackers to steal users’ entire crypto wallets. As said, OpenSea has been the biggest marketplace for buying, selling, and trading NFTs and other digital collectibles.
CheckPoint came across the vulnerability for the first time following reports of stolen crypto wallets triggered by airdropped NFTs. The Check Point researchers later discovered critical security issues “that, if exploited, could have led hackers to hijack user accounts and steal entire crypto wallets of users, by sending malicious NFTs”.
