Perun CKB contracts
This repository contains the scripts used to realize Perun channels on CKB. There are three scripts available:
This script is used to handle access-rights to the live Perun channel cell. It ensures that only participants of the Perun channel in question are able to consume the live channel cell.
This script is used to handle a Perun channel's state progression on-chain. Basically a NFT script with extra functionality.
This script handle access rights to all funds belonging to a Perun channel. It ensures that only channel participants are able to consume said funds.
Update the rustc version to 1.85.0 and install the following:
sudo apt install gcc-riscv64-unknown-elf binutils-riscv64-unknown-elf \
libc6-dev-riscv64-cross libc6-riscv64-cross linux-libc-dev-riscv64-cross
wget https://apt.llvm.org/llvm.sh && chmod +x llvm.sh && sudo ./llvm.sh 18 && rm llvm.sh
cargo install cargo-generate
Add the target:
rustup target add riscv64imac-unknown-none-elf
Build contracts:
chmod +x ./setup_env.shmake preparesource ./setup_env.sh build && make buildRun tests:
source ./setup_env.sh test && make testor run them using the IDE
Additionally, to the available contracts we extracted common functionality into
its own perun-common crate which gives some additional helpers and
convenience functions when interacting with types used in Perun contracts.
A common issue when compiling for RISC-V is the missing file: gnu/stubs-lp64.h
If the necessary packages are already installed, the file /usr/riscv64-linux-gnu/include/gnu/stubs-lp64d.h
should exist instead. This is due to the toolchain using the lp64d ABI (which includes double-precision floating point support) rather than plain lp64.
To resolve this, simply create a symbolic link:
sudo ln -s /usr/riscv64-linux-gnu/include/gnu/stubs-lp64d.h /usr/riscv64-linux-gnu/include/gnu/stubs-lp64.h
Then try compiling again.
