Lately, there has been a lot of discussion regarding Ethereum’s total supply. It seems as though most Ethereum block explorers provide a different amount even though they all read the same block number. This is in part due to how each explorer records the circulating supply. Some take into consideration lost/stolen/burned Ether while others do not. For example Marc-André Dumas created a script to calculate total supply.

Marc-André Dumas @marcandu My ethsupply script was counting some uncle rewards twice, which led to the discrepancy. Many thanks to @junderwood4649 for identifying the bug and everyone else who reviewd the code. As you will see below, the delta with Etherscan is now only 3 ETH. github.com/madumas/ethsup…

Not only has Marc-André provided a script to do the calculation but so has the Nethermind and Geth teams. Until a few days ago these scripts weren’t open source and since most people don’t run a full Ethereum node (the state of the blockchain), it is not surprising this has never really came up. Udi Wertheimer provides pretty good insight as to the differences between how proponents of Ethereum and Bitcoin think about the respective technology/money.

Udi Wertheimer @udiWertheimer I salute @bitstein and @pierre_rochard for their investigative work uncovering the ETH #supplygate. But it’s time to #articulate the steel man argument... God only knows that no one else can pull it off! Grab your cancellation torches and read the THREAD /1

Earn Opportunity

Gas Token presents a unique opportunity to arbitrage gas prices on Ethereum. You can either buy the token from uniswap.exchange in hopes gas prices will continue to go up or you can mint the token through the use of a smart contract which takes up storage space on-chain during times of low gas prices and burns the storage (in return for a refund) during times of high gas prices. More information can be found here. Gas prices can be tracked here.
