Can Blockstack steal the token crown from Ethereum?

With its compliance-focused approach and PhD-level technical team, Blockstack claims it will be the first organization to offer an SEC-approved token offering.

Blockstack Announces SEC Filing for $50M Regulated Token Offering

"We’ve been in a confidential submission process with the SEC, making progress as we drive towards an SEC-qualified token offering. Recently, U.S. markets have been closed to crypto projects given regulatory uncertainty, and we believe in opening the U.S. markets to innovation in this area... Upon qualification, we believe that this offering may be the first time a blockchain project receives approval to access the public U.S. securities markets. This can potentially set a precedent for others in the industry, not just for public offerings, but also as a path to launch new public blockchains and establish a path to bootstrapping decentralized ecosystems."

Story of 27550 lbs (12500 kg) of food and Venezuela

"We quickly developed a plan with Carlos to send him the Bitcoin and have him purchase everything he could from local markets and stores. We managed to find local vendors who we informed of our plans and they were so happy to hear of our efforts. They offered us amazing discounts on items to further our funds even more. By the time it was all said and done we ended up with 5000kg (11023 lbs) of chicken and 7500kg (16534 lbs) of rice and corn flour. Enough chickens were purchased for each person in the town."

Institutional Bitcoin Trading Volumes Move Back into Growth

"Institutional products have now moved into growth for the 4th month in a row hitting new highs against US-based exchanges as a % of total trading volume. Currently, this is almost 8% more than when Bitcoin hit its price peak in December 2018. While CBOE is by and far this biggest loser, Grayscale's Bitcoin Investment Trust (GBTC) traded on the OTCMarkets has also lost its dominance. At the start of 2018, GBTC accounted for over 50% of the market share across the three institutional products, now standing at under 24%."

Options Finally Come to Ethereum and Bitcoin

"Deribit, an Amsterdam based crypto exchange which has been operating since 2016, now allows you to trade bitcoin or eth options, as well as futures... The explainer page for options says they use the Deribit ETH index, which is composed of the spot price at Bitfinex, Gemini, Bitstamp, GDAX, Kraken and Itbit. These are cash settled options in as far as you receive the difference of winning and losses, rather than the actual assets. No cash exchanges hands, however. Only eth or bitcoin can be deposited and withdrawn from the exchange."

Oil Producers Are Burning Enough 'Waste' Gas to Power Every Home in Texas

"America’s hottest oil patch is producing so much natural gas that by the end of last year producers were burning off more than enough of the fuel to meet residential demand across the whole of Texas. The phenomenon has likely only intensified since then. Flaring is the controversial but common practice in which oil and gas drillers burn off gas that can’t be easily or efficiently captured and stored. It releases carbon dioxide and is lighting up the skies of West Texas and New Mexico as the Permian Basin undergoes a massive production boom."

GitHub Has Become A Haven For China's Censored Internet Users

"Tech-savvy programmers in the world's most thoroughly censored cyberspace are turning to unconventional means to collectively organize. They created a 'repository,' or collaborative project, onGitHub called '996.ICU,' based on a joke that a 996 schedule will send you to the intensive care unit. It's become one of the most popular projects on GitHub, with more than 200,000 GitHub members following the project."

Cryptocurrencies are ‘clearly shaking the system,’ IMF’s Lagarde says

"'I think the role of the disruptors and anything that is using distributed ledger technology, whether you call it crypto, assets, currencies, or whatever ... that is clearly shaking the system,' she said. The IMF boss warned that such financial industry changes must be accompanied by regulation. 'We don’t want innovation that would shake the system so much that we would lose the stability that is needed,' she said."

Blockchain Could Be Used By At Least 50% Of All Companies Within 3 Years, Oracle Exec Says

"'My projection is that between 50% and 60% of companies will use blockchain in the next few years,' said Frank Xiong, Oracle's group vice president of blockchain product development at the Forbes CIO Summit in Half Moon Bay, California, Monday. The enterprise software maker has more than 100 customers using its blockchain platform to track items for purposes such as ensuring the Italian olive oil you're buying was really made in Italy and that a manufacturer isn't buying minerals that support armed conflicts. But it's not a magic bullet."

Amazon Workers Are Listening to What You Tell Alexa

" Inc. employs thousands of people around the world to help improve the Alexa digital assistant powering its line of Echo speakers. The team listens to voice recordings captured in Echo owners’ homes and offices. The recordings are transcribed, annotated and then fed back into the software as part of an effort to eliminate gaps in Alexa’s understanding of human speech and help it better respond to commands."

Towards Proof-of-Work Cryptocurrency Valuation: Mining Games, Network Effects and the Social Value of Blockchain

"In this study, a mathematical model of proof-of-work cryptocurrency valuation is developed based on the concepts of simultaneous equilibria in two mining games, the purchasing power parity in the system of equations of exchange and the network effects of transaction cost optimization in the economy where agents utilise both conventional and digital currencies to process payments. The model lays the foundation for rigorous long-term proof-of-work cryptocurrency valuation superior to existing approaches that are solely based on variations of Metcalfe’s law or costs of mining."

Towards a First Step to Understand the Cryptocurrency Stealing Attack on Ethereum

"We performed the first systematic study of a new attack on Ethereum to steal cryptocurrency. The attack is due to the unprotected JSON-RPC endpoints existed on Ethereum nodes that could be exploited by attackers to transfer Ether and other ERC20 tokens to attackers-controlled accounts. This study sheds light on the attack, including malicious behaviors involved and profits of attackers. ... The further behavior analysis showed that attackers were following a three-steps pattern to steal the Ether. Moreover, we observed an interesting type of transaction called zero gas transaction, which has been leveraged by attackers to steal ERC20 tokens. At last, we estimated the overall profits of attackers. To engage the whole community, we will release the dataset of all captured attacks by our system."

Cryptology ePrint Archive: Report 2019/328

"Since balances are not announced, second-layer nodes probe routes iteratively, until they find a successful route to the destination for the amount required, if any. This feature makes the routing discovery protocol less efficient but preserves the privacy of channel balances. In this paper, we present an attack to disclose the balance of a channel in the Lightning Network. Our attack is based on performing multiple payments ensuring that none of them is finalized, minimizing the economical cost of the attack. We present experimental results that validate our claims, and countermeasures to handle the attack."
