There are legitimate concerns about security on Ethereum. With such a complex system, and so many different programs running on it, the attack surface is large. And given the challenges the community faces in migrating to Ethereum 2.0, including a new proof-of-stake consensus mechanism and a sharding solution for scaling transactions, it’s still not assured it will ever be ready for prime time.

So, let’s dismiss claims like those of Ethhub.io co-founder Anthony Sassano. He argued that because bitcoin token transactions on Ethereum deny miners fees they would otherwise receive on the bitcoin chain, bitcoin is becoming a “second-class citizen” to ether. You’d hardly expect people in countries where dollars are preferred to the local currency to think of the former as second class. And just as the U.S. benefits from overseas demand for dollars – via seignorage or interest-free loans – bitcoin holders benefit from its sought-after liquidity and collateral value in the Ethereum ecosystem, where it lets them extract premium interest.
OF MONEY AND MYTHS. I’m reading Stephanie Kelton’s book “The Deficit Myth.” In a future edition of Money Reimagined, I’ll have more to say on the most influential modern monetary theory proponent’s explanation of its ideas. But for now I’ll just say that, while I’m not likely to be a convert to all its prescriptions, it seems clear that MMT is widely misunderstood by folks on both the left and the right – also, very much by the crypto industry. The latter is perhaps because people in crypto tend to skew more to the metallist school of money, rather than to chartalism. Either way, a clearer grasp of what MMT is all about would, I believe, help improve the industry’s discussion around government, money, trust and how blockchain-based systems can integrate with the existing one.
Like other blockchains, Ethereum has a native cryptocurrency called Ether (ETH). ETH is digital money. If you’ve heard of Bitcoin, ETH has many of the same features. It is purely digital, and can be sent to anyone anywhere in the world instantly. The supply of ETH isn’t controlled by any government or company – it is decentralized, and it is scarce. People all over the world use ETH to make payments, as a store of value, or as collateral. The latest news about Ethereum mostly concerns the move to Serenity the last post-development phase of Ethereum as well as changing Ether mining’s concept from Proof-of-Work to Proof-of-Stake in order to reduce the power cost of the process.
