In the early hours of March 1st, Ethereum upgraded Constantinople and St. Petersburg in the form of hard forks.
According to the previous plan, the upgrade was carried out in the 7,280,000 block of the Ethereum network. Constantinople has brought a number of performance improvements to the platform, including reducing transaction costs for certain operations on the Ethereum network. The hard fork of Constantinople was originally carried out on January 15th, but because the Ethereum team discovered a security hole that allowed the hacker to reentrancy attack, it was requested to delay the upgrade a few hours before the official launch.
The Ethereum team pointed out that the reason for the upgrade was the name “Constantinople” and “St. Petersburg” because the initial upgrade of the network in Constantinople was postponed and must be carried out twice in the same block. The agreement was upgraded to fix various problems on the various Ethereum test networks. In addition, the vulnerability discovered earlier came from the EIP-1283 proposal in “Constantinople”. The team hopes to remove the proposal from the test network through the “St. Petersburg” upgrade.
Ethernodes.org shows that not all Ethereum users have adopted these updates, only 23.8% of Geth and 41% of Parity customers are already running a version compatible with Constantinople.
According to CoinMarketCap, as of press time, Ethereum (ETH) is down 0.45% to $137.47.
