BadgerDAO reported on Wednesday that it lost about 2,100 bitcoin and 151 ether in a hacking attack.
Kryptobi, who said he is on the BadgerDAO support team and has been looking into the hack, told Motherboard that it appears someone injected a malicious script into BadgerDAO’s frontend after compromising an API key for BadgerDAO’s Cloudflare account. Cloudflare is a web infrastructure, content delivery network, and website security company, which is used by millions of sites on the internet.
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.
Blockchain Coinvestors has released its predictions for 2022. Every year the team publishes their predictions for the year ahead.
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.

As part of the platform’s push toward decentralization, Twitter created a crypto team that will report to the company’s CTO.
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.
Cybersecurity expert Mashael Al Sabah was recently featured on MIT’s Business Lab podcast. She talks about privacy issues with blockchain technology and how they can be fixed. You can listen to the podcast with the link below (direct link on Apple Podcasts), and.or read the podcast transcript.
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.
Security researcher Gerhard Wagner found a double-spend bug in Polygon’s Plasma bridge. The company awarded Mr. Wagner a record US$2 million for reporting this critical vulnerability.
In total, it is possible to create 14×16 = 224 different encodings for the same raw path. A malicious user can leverage the issue to create alternative exits for the same burn transaction and perform double spends on the Polygon network.
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.
The Associated Press announced a partnership with Chainlink to bring datasets onto leading blockchains.
AP U.S. race calls, economic data, sports game outcomes and business financials will be available. The data can be used to automate key processes that happen on-chain, including informing markets of election race calls, triggering an on-chain trade when a company’s quarterly financials are released, or augmenting the appearance of non-fungible tokens based on real-world events.
Polygon and DraftKings have “formed a strategic agreement” to adopt NFTs and Web3 technologies with DraftKings Marketplace.
To participate in the marketplace, users can browse listings on the marketplace’s website. Preseason Access Collection NFT drops by Autograph of iconic athletes featuring Tom Brady, Wayne Gretzky, Naomi Osaka, Simone Biles, and Derek Jeter, were sold out almost immediately since the launch of the platform in August.
According to a recent rule change, developers who want to publish games on Steam can’t integrate NFTs or other blockchain technology.
Coinbase is preparing to launch its own NFT platform to take on rivals like OpenSea. You can sign up for the waitlist if you live in the U.S.
Visa has announced a Layer 2 project for cryptocurrency that aims to be a universal exchange hub for stablecoins and central bank digital currencies (CBDC).
The idea is to create a digital currency equivalent of the existing international payment experience—one that lets you pay for something in another country with a debit or credit card that draws funds from an account in your home country.
Also: “Visa, for instance, says the proposed base layer for its universal payments channel is Ethereum.”
David Shuttleworth wrote a nice write-up to explain decentralized autonomous organizations (DAO). These are blockchain-related entities where power is shared by everyone.
Ultimately, a DAO is governed entirely by its individual members who collectively make critical decisions about the future of the project, such as technical upgrades and treasury allocations.
Binance announced support for Unstoppable Domains on Wednesday. This gives customers easy NTF domain names like “username.wallet.”
One of the promises of blockchain is that it will enable Web3. While it may not be here yet, there are decentralized services you can use today.
Coinbase announced on Wednesday support for Horizen (ZEN) and Braintrust (BTRST). These can be traded on Coinbase Pro.
New World Inc, a subsidiary of Graph Blockchain, announced its intention to create NFTs using 3D scanning. These allow them to be viewed in an immersive environment using AR/VR.
For example, Contributors can create holograms of their favorite athlete, fabricate an unconventional piece of furniture, design a high-end piece of clothing, or create abstract pieces of art, all derived from objects in the tangible world.
Brazilian singer, songwriter, and dancer Naldo Benny is the most recent celebrity to team up with New World to create an NFT through 3D scanning. Naldo tracked his signature dance moves and mannerisms that were translated into a digital avatar by New World’s creative team and sold as an NFT.
This seems cool to me, and more of what I envision NFTs to be: Virtual representations of physical objects.
