2019-11-15 Upgrade Testnet
On Nov 15, 2019 the Bitcoin Cash network will undergo a planned protocol upgrade, as part of a series of regularly scheduled network upgrades. The changes have been specified and implemented three months prior to upgrade activation in order to permit the ecosystem to prepare well in advance.
To assist technical preparations for the upgrade, a testnet is available where the upgrade features can be trialed and tested. Node implementations, wallets, businesses and services built on the Bitcoin Cash network can use this testnet to ensure compatibility, or to get started building products to make use of the upgrade features. This document outlines the information needed to participate in this upgrade testnet.
Upgrade Testnet Parameters
1566227700 (August 19, 2019 15:15:00 UTC)
Last old-rules block hash (height=1322706, mediantime=1566228221):
First new-rules block hash (height=1322707):
This block contains a Schnorr multisig transaction.
Set up a node
Run Bitcoin ABC 0.20.0 with:
bitcoin-qt -testnet -gravitonactivationtime=1566227700 -addnode=testnet.imaginary.cash
Alternatively as bitcoin.conf file:
testnet=1 addnode=testnet.imaginary.cash gravitonactivationtime=1566227700
You should also run this to avoid soft-forking back onto normal testnet:
bitcoin-cli -testnet invalidateblock 000000000000067656459385ff54b1178d985a5334f40e209c1e3580c08cc18b
user: (testnet address) password:(anything)
testnet.imaginary.cash:50002 will follow the bitcoind.
