# Nethermind-Nimbus theMerge
|
||
|
|
|
||
|
|
## How To Run
|
||
|
|
|
||
|
|
This testnet requires 2 terminal processes, one for Nethermind, one for a Nimbus node. See the per-terminal commands below.
|
||
|
|
|
||
|
|
## Terminal 1: Nethermind
|
||
|
|
|
||
|
|
### Install dotnet:
|
||
|
|
```
|
||
|
|
https://dotnet.microsoft.com/download
|
||
|
|
```
|
||
|
|
|
||
|
|
### Build Nethermind:
|
||
|
|
```
|
||
|
|
git clone https://github.com/NethermindEth/nethermind.git --recursive -b themerge
|
||
|
|
cd src/Nethermind
|
||
|
|
dotnet build Nethermind.sln -c Release
|
||
|
|
# if src/Nethermind/Nethermind.Runner/bin/Release/net5.0/plugins has no Nethermind.Merge.Plugin.dll plugin then you may need to run the build again
|
||
|
|
dotnet build Nethermind.sln -c Release
|
||
|
|
cd Nethermind.Runner
|
||
|
|
```
|
||
|
|
|
||
|
|
run Nethermind
|
||
|
|
```
|
||
|
|
rm -rf bin/Release/net5.0/nethermind_db
|
||
|
|
dotnet run -c Release --no-build -- --config themerge_devnet_m3
|
||
|
|
```
|
||
|
|
|
||
|
|
## Terminal 2: Nimbus
|
||
|
|
```
|
||
|
|
git clone https://github.com/status-im/nimbus-eth2.git -b amphora-merge-interop
|
||
|
|
make update -j$(nproc)
|
||
|
|
make nimbus_beacon_node -j$(nproc)
|
||
|
|
```
|
||
|
|
|
||
|
|
### Verify
|
||
|
|
```
|
||
|
|
./env.sh nim c -r tests/test_merge_vectors.nim
|
||
|
|
```
|
||
|
|
it may be needed to disable CPU instructions (e.g. when you run it inside Windows Subsystem for Linux)
|
||
|
|
```
|
||
|
|
./env.sh nim c -r -d:disableMarchNative tests/test_merge_vectors.nim
|
||
|
|
```
|
||
|
|
if you have a linking error mentioning libbacktrace then you can disable it as well:
|
||
|
|
```
|
||
|
|
./env.sh nim c -r -d:disableMarchNative -d:disable_libbacktrace tests/test_merge_vectors.nim
|
||
|
|
```
|
||
|
|
|
||
|
|
replace the JSON RPC port for test vectors
|
||
|
|
```
|
||
|
|
vi tests/test_merge_vectors.nim
|
||
|
|
# then change the line below
|
||
|
|
let web3Provider = (waitFor newWeb3DataProvider(
|
||
|
|
default(Eth1Address), "ws://127.0.0.1:8550")).get
|
||
|
|
```
|
||
|
|
|
||
|
|
replace the JSON RPC port for local testnets
|
||
|
|
```
|
||
|
|
vi scripts/launch_local_tetsnet.sh
|
||
|
|
# then change the line below
|
||
|
|
WEB3_ARG="--web3-url=ws://127.0.0.1:8551"
|
||
|
|
```
|
||
|
|
|
||
|
|
### Run
|
||
|
|
|
||
|
|
```
|
||
|
|
export NIMFLAGS="-d:disableMarchNative -d:disable_libbacktrace"
|
||
|
|
./scripts/launch_local_testnet.sh --preset minimal --nodes 4 --disable-htop --stop-at-epoch 7 -- --verify-finalization --discv5:no
|
||
|
|
```
