Ethereum's Constantinople Upgrade Stalls on Testnet
Ethereum's main test network, Ropsten, is currently at a standstill.
Code for ethereum's upcoming hard fork, dubbed Constantinople, was set to be activated on Ropsten at block number 4,230,000.
However, according to blockchain explorer sites such as Etherscan and Blockscout, the current Ropsten network is stalled at block 4,299,999. Afri Schoedon, release manager for the ethereum client Parity, explained that the reason for the stall was a lack of miners on the Ropsten network to push the newly upgraded blockchain forward, he wrote in a public Gitter channel
In other words, though Constantinople was released to Ropsten, miners failed to upgrade their software.
