Ethereum Upgrades as Hard Forks Constantinople and St Petersburg Activate on Blockchain

Two long-anticipated upgrades appear to have officially activated on the ethereum blockchain, the world's second-largest by market value, without incident. As seen on blockchain monitoring website Fork Monitor, there is so far no evidence of a chain split that would suggest a portion of ethereum users are still running an older ethereum software. Past hard forks of the ethereum blockchain have encountered such setbacks, most notably in 2016 with ethereum classic, a group that continued running an older software instance when a controversial upgrade was introduced.
As background, before any system-wide upgrade, or hard fork, miners and node operators are required to install new client software that automatically updates at the exact same block number. "With the blockchain, everyone has to upgrade in order for everyone to be able to use [the new] features," explained Taylor Monahan - CEO of blockchain wallet tool MyCrypto. MyCrypto presently runs 10 to 15 computer servers also called nodes all running on the most updated version of the Parity ethereum client.
With today's release of Constantinople and St. Petersberg, four different ethereum improvement proposals have been officially activated on the ethereum network - one of which does introduce a new "Corner case" affecting smart contract immutability.
