At 2:43am EST on September 15, 2022, the first Ethereum block was validated using Proof of Stake, signaling the success of the Ethereum Merge, one of the most anticipated events in blockchain and computer science history. The Merge shifted the Ethereum blockchain (native token ETH, or ether) from a proof-of-work (PoW) consensus mechanism to a … Continue Reading
As of this writing, the Ethereum “Merge,” one of the most anticipated events in blockchain history, is finally expected to occur in September 2022. The “Merge” will shift the Ethereum blockchain (native token ETH, or ether) from a proof-of-work (PoW) consensus mechanism to a proof-of-stake (PoS) consensus mechanism that uses over 99.9% less energy. Technically, … Continue Reading
On January 20, 2022, the U.S. House Committee on Energy and Commerce (the “Committee”) held a hearing on the energy consumption associated with cryptocurrency activity. In announcing the hearing on January 12, 2022, Committee Chairman Frank Pallone (D-NJ) and Oversight and Investigations Chair Diana DeGette (D-CO) stated: “In just a few short years, cryptocurrency has … Continue Reading
On August 6, 2021, the Securities and Exchange Commission (SEC) announced that it had charged two men, Gregory Keough and Derek Acree, and their company, Blockchain Credit Partners, doing business as DeFi Money Market (collectively, the “Respondents”), for unregistered sales of more than $30 million of securities using smart contracts and so-called “decentralized finance” (DeFi) … Continue Reading
Once purely theoretical, “majority” or “51%” attacks on public blockchains have dealt participants a reality check: The fundamental assumption of Satoshi Nakamoto’s 2008 Bitcoin whitepaper (that computing power will remain sufficiently decentralized in blockchain networks that rely on a “proof-of-work” consensus mechanism) can in practice actually be exploited to enable double spending. “The system is … Continue Reading
In remarks made at the Yahoo! All Markets Summit in New York, Heath Tarbert, Chairman of the U.S. Commodity Futures Trading Commission (CFTC), said that he believed the Ether cryptocurrency was a “commodity” and should be regulated under the Commodity Exchange Act (CEA). This statement follows the agency’s December 2018 announcement that it was seeking … Continue Reading
At last week’s Yahoo! All Markets Summit in Palo Alto, SEC Division of Corporation Finance Director William Hinman delivered a speech sure to send shockwaves through the crypto world. Applying the Howey test (which sets forth the elements necessary for determining whether a transaction involves the offer or sale of an “investment contract” and thus, … Continue Reading
Virtual worlds similar to the OASIS in Steven Spielberg’s upcoming film Ready Player One may be closer than we think – and provably scarce, blockchain-based digital assets could provide the leap forward that gets us there. Already, developers are testing early implementations. Since CryptoKitties launched at the end of 2017, promptly causing a traffic jam … Continue Reading
The recent Parity wallet “freeze” provides yet another example of a coding vulnerability in a smart contract (rather than a flaw in the underlying blockchain or cryptography) resulting in an exploit that compromises cryptocurrency worth millions. It again highlights some of the pitfalls of insecure code in the context of digital assets and raises questions … Continue Reading
