Hi All,
Apologies for the late posting of the agenda. The 4th CTV meeting will be
held tomorrow at 12:00 PT in ##ctv-bip-review in Libera.chat.
Tomorrow the conversation will be slightly more tutorial focused. If you
have time in advance of the meeting, it might be good to do some of this in
advance.
1) Discussion: What is the goal of Signet? (20 minutes)
- Do we have a "decision function" of observations from a test network?
- What applications should be prototyped/fleshed out?
- What level of fleshed out matters?
- Should we add other experiments in the mix on this net, like
APO/Sponsors?
- Should we get e.g. lightning working on this signet?
2) Connecting to CTV Signet Tutorial (10 mins)
We'll make sure everyone who wants to be on it is on it & debug any issues.
*Ahead of Meeting: Build this
branch https://github.com/JeremyRubin/bitcoin/tree/checktemplateverify-signet-23.0-alpha
<https://github.com/JeremyRubin/bitcoin/tree/checktemplateverify-signet-23.0-alpha>*
Connect to:
```
[signet]
signetchallenge=512102946e8ba8eca597194e7ed90377d9bbebc5d17a9609ab3e35e706612ee882759351ae
addnode=50.18.75.225
```
3) Receiving Coins / Sending Coins (5 mins)
There's now a faucet for this signet: https://faucet.ctvsignet.com
And also an explorer: https://explorer.ctvsignet.com
4) Sapio tutorial (25 minutes)
*Ahead of meeting, if you have time: skim https://learn.sapio-lang.org
<https://learn.sapio-lang.org> & download/build the sapio cli & plugin
examples*
We'll try to get everyone building and sending a basic application (e.g.
congestion control tree or vault) on the signet (instructions to be posted
before meeting).
We won't use Sapio Studio, just the Sapio CLI.
5) Sapio Q&A (30 mins)
After some experience playing with Sapio, more general discussion about the
project and what it may accomplish
6) General Discussion (30 minutes)
Best,
Jeremy

Hi Devs,
As promised, a Sapio Tutorial. In this tutorial we'll walk through how to
use the Sapio CLI to generate contracts and play with them on the network.
We'll use a congestion control tree because it's very simple! We will walk
through this step-by-step during the meeting today.
-1. Install JQ (json manipulating tool) if you don't have it / other things
needed to run a bitcoin node.
0. Set up a node as described above. You'll likely want settings like this
in your bitcoin.conf too:
[signet]
# generate this yourself
rpcauth=generateme:fromtherpcauth.pyfile
txindex=1
signetchallenge=512102946e8ba8eca597194e7ed90377d9bbebc5d17a9609ab3e35e706612ee882759351ae
rpcport=18332
rpcworkqueue=1000
fallbackfee=0.0002
Get coins https://faucet.ctvsignet.com/ / DM me
1. Follow the install instructions on
https://learn.sapio-lang.org/ch01-01-installation.html You can skip the the
sapio-studio part / pod part and just do the Local Quickstart up until
"Instantiate a contract from the plugin". You'll also want to run *cargo
build --release* from the root directory to build the sapio-cli.
2. Open up the site https://rjsf-team.github.io/react-jsonschema-form/
3. Run *sapio-cli contract api --file
plugin-example/target/wasm32-unknown-unknown/debug/sapio_wasm_plugin_example.wasm*
4. Copy the resulting JSON into the RJSF site
5. Fill out the form as you wish. You should see a JSON like
{
"context": {
"amount": 3,
"network": "Signet",
"effects": {
"effects": {}
}
},
"arguments": {
"TreePay": {
"fee_sats_per_tx": 1000,
"participants": [
{
"address": "tb1pwqchwp3zur2ewuqsvg0mcl34pmcyxzqn9x8vn0p5a4hzckmujqpqp2dlma",
"amount": 1
},
{
"address": "tb1pwqchwp3zur2ewuqsvg0mcl34pmcyxzqn9x8vn0p5a4hzckmujqpqp2dlma",
"amount": 1
}
],
"radix": 2
}
}
}
You may have to delete some extra fields (that site is a little buggy).
Optionally, just modify the JSON above directly.
6. Copy the JSON and paste it into a file ARGS.json
7. Find your sapio-cli config file (mine is at
~/.config/sapio-cli/config.json). Modify it to look like (enter your
rpcauth credentials):
{
"main": null,
"testnet": null,
"signet": {
"active": true,
"api_node": {
"url": "http://0.0.0.0:18332",
"auth": {
"UserPass": [
"YOUR RPC NAME",
"YOUR PASSWORD HERE"
]
}
},
"emulator_nodes": {
"enabled": false,
"emulators": [],
"threshold": 1
},
"plugin_map": {}
},
"regtest": null
}
8. Create a contract template:
*cat ARGS.json| ./target/release/sapio-cli contract create --file
plugin-example/target/wasm32-unknown-unknown/debug/sapio_wasm_plugin_example.wasm
| jq > UNBOUND.json*
9. Get a proposed funding & binding of the template to that utxo:
*cat UNBOUND.json| ./target/release/sapio-cli contract bind | jq >
BOUND.json*
10. Finalize the funding tx:
*cat BOUND.json | jq ".program[\"funding\"].txs[0].linked_psbt.psbt" |
xargs echo | xargs -I% ./bitcoin-cli -signet utxoupdatepsbt % | xargs -I%
./bitcoin-cli -signet walletprocesspsbt % | jq ".psbt" | xargs -I%
./bitcoin-cli -signet finalizepsbt % | jq ".hex"*
11. Review the hex transaction/make sure you want this contract... and then
send to network:
*./bitcoin-cli -signet sendrawtransaction
020000000001015e69106b2eb00d668d945101ed3c0102cf35aba738ee6520fc2603bd60a872ea0000000000feffffff02e8c5eb0b000000002200203d00d88fd664cbfaf8a1296d3f717625595d2980976bbf4feeb10ab090180ccdcb3faefd020000002251208f7e5e50ce7f65debe036a90641a7e4d719d65d621426fd6589e5ec1c5969e200140a348a8711cb389bdb3cc0b1050961e588bb42cb5eb429dd0a415b7b9c712748fa4d5dfe2bb9c4dc48b31a7e3d1a66d9104bbb5936698f8ef8a92ac27a650663500000000*
12. Send the other transactions:
*cat BOUND.json| jq .program | jq ".[].txs[0].linked_psbt.psbt" | xargs -I%
./target/release/sapio-cli psbt finalize --psbt % | xargs -I%
./bitcoin-cli -signet sendrawtransaction %*
Now what?
- Maybe load up the Sapio Studio and try it through the GUI?
- Modify the congestion control tree code and recompile it?
- How big of a tree can you make (I did about 6000 last night)?
- Try out other contracts?
