Antelope is an open framework for building fast, secure, and user-friendly Web3 products and services.

Updating Network Nodes

There are quite a few publications covering this topic already, but one more should not do any harm.

Step 1- Clone

From your server CLI, download the repository onto your machine:
git clone --recursive

Step 2 - Checkout Release Tag or Branch

The repository would be in a directory called "leap". Go into the directory:
cd leap

Open the readme file which contains all the installation instructions:

Change from the main branch to the v5.0.0 branch:
git fetch --all --tags
git checkout v5.0.0

Once you have all the dependencies, run the following command from within the "leap directory":
git pull
git submodule update --init --recursive

Step 3 - Build

Make sure to follow the instructions for your operating system.
You first need to install all the required dependencies.
sudo apt-get update

Here is the list for Ubuntu 20.04 and 22.04:
- build-essential
- cmake
- git
- libcurl4-openssl-dev
- libgmp-dev
- llvm-11-dev
- python3-numpy
- python3-numpy
- file
- zlib1g-dev

You can install these using
sudo apt-get install -y

On Ubuntu 20.04 you need to install gcc-10 which has C++20 support:
sudo apt-get install -y g++-10

Next, create a build directory:
mkdir -p build

Go into the build directory:
cd build

Build (Ubuntu 20.04):

Build (Ubuntu 22.04):
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=/usr/lib/llvm-11 ..

Step 4 - Test

Once the installation is complete, run the parallelizable tests as shown in the readme file:
ctest -j $(nproc) -LE _tests
ctest -j $(nproc) -L wasm_spec_tests

There are non-parallelizable tests, but they take a long time to complete.
These are not recommended, but you should at the very least run the first parallelizable test.

Once these tests complete successfully, you can install and start Nodeos v5.0.0

Step 5 - Install

make -j $(nproc) package

You can specify the number of threads to use by replacing the $(nproc) with the number of threads to use. Roughly 2Gb RAM per j value is required.

My operating system is Ubuntu 22 so I've not gone through the installation for 20, but if you are using 20 just follow the instructions in the readme file.

Quick Sync to the Network

You can use one of the snapshots we saved to get up and running quickly.
- Snapshots

It is recommended to go through the upgrade on the TestNet first.
