Hackers pumping a crypto giveaway scam appear to have compromised the Twitter accounts of leading exchanges, individuals and at least one news organization.

The unknown attackers tweeted identical messages promising that they were “giving back 5000 BTC ($45,889,950) to the community” on Wednesday afternoon from the accounts of Gemini, Binance, KuCoin, Coinbase, Litecoin’s Charlie Lee, Tron’s Justin Sun, Bitcoin, Bitfinex, Ripple, Cash App, Elon Musk, Uber, Apple, Kanye West, Jeff Bezos, Michael Bloomberg, Warren Buffett, Barack Obama and CoinDesk.

At least some of the compromised accounts have multi-factor authentication enabled. The address linked to the scam appears to have received more than 11.3 BTC, or roughly $103,960.

Shares of Twitter fell as much as 3% in after-hours trading.”

Ethereum 2.0 client Prysm is “basically ready” to launch. Lighthouse is halfway through an independent audit as well.

Prysm client’s code was ‘well-written and documented.’ The firm identified 65 issues relating to the granularity of timestamps, pseudo-random number generation and second pre-image attacks on Merkle trees.

Ma described the concerns as “low-level optimizations,” with 75% having been addressed already. Ten engineers combed over Prysm’s ETH 2.0 codebase, programmed in the Go language, for two months.

However, where money is on the line, audits alone don’t greenlight code for launch. Eth 2.0 clients have joined various testnets to run simulations of Phase 0 throughout the spring months.”

“During rigorous stress testing, the Matic Network CS-2008 testnet was able to reliably handle a performance level of 7,200 TPS! This level of performance can be reliably extrapolated to the Matic mainnet.

During stress testing, 122 validators were active and running validator+sentry nodes. Thus, the network was truly decentralized, ensuring reliable results.

We will continue to optimize the network for even greater performance. Regardless, the current performance capabilities of the network as it stands means that Matic can be instrumental in helping the Ethereum ecosystem to overcome its performance constraints and reach its full potential.”

“Non fungible tokens (NFT) representing diamonds have made their way to the OpenSea marketplace.

Before they are tokenized, all diamonds are certified by the Gemological Institute of America (GIA) and are then sent to the Gem Certification & Assurance Lab (GCal) , which audits the GIA certificate and provides a guarantee.

The problem that Icecap solves is that it is currently almost impossible for retail investors to sell diamonds without a steep discount as there is no secondary market. According to Voorhees, this is an untapped $10 billion opportunity.”

“SEBA said it is the first digital bank to offer clients the ability to issue and invest in blockchain tokens that represent real tradable assets like treasury bonds or foreign exchange contracts on the open-source blockchain platform Corda.

SEBA said in its statement that it will create a custodial wallet for customers, issue digital securities and distribute them to investor networks.”

“The New York-based fund provider reported two consecutive record quarters Wednesday, with more than $400 million increase in capital inflows quarter-on-quarter. Overall, Grayscale raised $1.4 billion in the first half of this year.

The vast majority of commits (85%) came from institutional investors in H1 2020; Grayscale said most have started diversifying away from just bitcoin.”

“China wants to trial its digital yuan using online food seller Meituan-Dianping, as well as another two Tencent-backed companies.

Listed in Hong Kong, Meituan-Dianping’s 400 million active users make it one of the largest food delivery platforms in the world. Tencent, which also owns popular messaging and payments app WeChat, is set to be one of the primary commercial issuers for the digital yuan when it goes live.”

“A former Coinbase user who last August received the now-infamous Internal Revenue Service (IRS) crypto letter is suing to block the tax agency from unlawfully seizing private financial records.

Harper’s case is an opportunity to put some checks on the power of the administrative state.

If they acquired it via the Coinbase summons – and we don’t know that for sure – it was a defective process that denied me the opportunity to contest the seizure of my data.

I’ll be seeking destruction of the records in the IRS’s control. A win would allow all recipients of the letter to seek the same.”
