BCH testnet4 for May 2022 network upgrade (updated, 2021-11-23)

**BCHN Technical Bulletin 2021-09-15 (updated 2021-11-23)** We now have a **testnet4** fork up for people to test-drive the Native Introspection and 64-bit Integers upgrade! Download the v24.0.0 release here: https://github.com/bitcoin-cash-node/bitcoin-cash-node/releases/tag/v24.0.0 Connect your node to one of the following nodes `testnet4.imaginary.cash:28333` `t4fork.c3-soft.com:28333` and make the following configuration change to follow the test fork: `-testnet4=1` `-upgrade8activationtime=1637694000` as well as run `bitcoin-cli invalidateblock 000000007810de1afbeffe07fc6545b882390ec0b4627f143249357b9355f5ac` After the above invalidation, your chain should contain the fork block: `00000000642ee3a09626b76fe983d1a37f79974ce032d526b1d94a5956786799` Connect your Electron-Cash client with `--testnet4` specified to: `t4fork.c3-soft.com:61002` (takes nonstandard transactions) `testnet4.imaginary.cash:50002` (enforces standardness) A block explorer for this testnet4 fork can be found at: https://testnet4.imaginary.cash If you want to accelerate mining for testing purposes, feel free to mine to: `stratum+tcp://t4fork.c3-soft.com:3333` (mines nonstandard transactions) `stratum+tcp://testnet4.imaginary.cash:3333` (enforces standardness) Bitcoin Unlimited and Knuth are set to join soon with their own clients. Happy testing!
