Fork Watcher

Runs different clients, such as Classic Geth and Parity, using multiple different versions and provides current status of synchronization:

• current blockchain height

• block hash at specified height

• for each used client instance

Currently configured for ECIP-1041 fork at block 5,900,000 with:

• Geth 4.2.2 - should fail to wrong fork, doesn’t support HF

• Geth 5.0.0 - first with HF support

• Geth 5.3.0 - latest stable

• Parity 1.9.2 - should fail to wrong fork, doesn’t support HF

• Parity 1.9.3 - first with HF support

• Parity 1.9.7 - latest stable in 1.9.x

• Parity 1.10.4 - latest stable
