I want to build a simple project with IOTA. First, I want to start a simple local/private Tangle network and then use wasp to write and run a smart contract.
My question is, which nodes can I use to run my local network, because In the docs of wasp they only talking about GoShimmer, What about the other nodes like Hornit and Bee? is GoShimmer & Wasp the only way now to have smart contract?
Thanks
Yes, wasp only connects to goshimmer nodes. Hornet & Bee are for the mainnet NOT development. Wasp has a really straightforward readme to build. Yes wasp-cli is how you currently interact with smart-contracts NFTs, etc.
I had some trouble with the docker image for goshimmer to work so I recommend just building the goshimmer node on whichever computer you are going to be messing with wasp. Wasp by default looks for localhost for the goshimmer node.
Simply clone the develop repo to your /opt/ directory:
git clone https://github.com/iotaledger/goshimmer.git
Then the thing you want to run is in goshimmer/scripts specifically build_goshimmer_rocksdb_builtin.sh. To build you just,
cd goshimmer
./scripts/build_goshimmer_rocksdb_builtin.sh
Then the goshimmer command will show up in the directory that you can execute. Here is a systemd service example if you want to make it a daemon service:
[Unit]
Description=Goshimmer node
[Service]
WorkingDirectory=/opt/goshimmer
ExecStart=/opt/goshimmer/goshimmer
[Install]
WantedBy=multi-user.target
If you are running arch-linux there already exists a supported go-shimmer repo in the aur and all you have to do is run
yay -S goshimmer-bin
You have a second topic that is harder to answer, how to start a private tangle. Not enough information to answer this (do you want a goshimmer private net or a private mainnet), make another post.
See the goshimmer docs: https://goshimmer.docs.iota.org/
This blog post "Exploring IOTA 2.0 Smart Contracts in a Private Network: Developing a Prediction Market" explains the steps to create 1 wasp-node with 1 goshimmer node to run an example smart-contract application; https://medium.com/51nodes/exploring-iota-2-0-smart-contracts-in-a-private-network-developing-a-prediction-market-c2d81988f75e
