MagicBlockは、Ephemeral Rollupというフルオンチェーンを実現する仕組みを提供している。
サンプルをそのまま動かすとエラーになるため（MagicBlockのソースが原因ではなくAnchor利用時の手順の問題で）、以下にその手順を記載する。
前提
以下のドキュメントやソースコードをもとに実行。
手順
- サンプルのダウンロード
% git clone https://github.com/magicblock-labs/magicblock-engine-examples.git
% cd magicblock-engine-examples/anchor-counter
- Yarnパッケージのインストール
% yarn
- anchor_counter-keypairとtoken_minter-keypairのKepairを削除
rm -rf target/deploy/*keypair*
- ProgramsのBuild & Deplory
% anchor build
% anchor deploy
Deploying cluster: https://api.devnet.solana.com
Upgrade authority: /Users/256hax/.config/solana/id.json
Deploying program "token_minter"...
Program path: /Users/256hax/Desktop/tmp/magicblock-engine-examples/anchor-counter/target/deploy/token_minter.so...
Program Id: EAharsbLZJUqW2uAL5nsmnVvufTCRpp2ysMs2myQ5wiQ

Deploying program "anchor_counter"...
Program path: /Users/256hax/Desktop/tmp/magicblock-engine-examples/anchor-counter/target/deploy/anchor_counter.so...
Program Id: HWw4L4y47mWmRajHRaKWhfcXxCprzMK47R75PDr7p4DT

Deploy success
これで、自分がデプロイしたtoken_minterとanchor_counterのProgramsのProgram Idが取得できていることがわかる。
（補足）
もし、ここでSOLが足りないと言われたら、以下からSOLをゲットする。
GitHub認証すると10SOLまで申請できる。
デプロイには2〜3SOLかかるので（デプロイ時にかかるが、そのあと概ねのSOLが戻って来る）、多めに用意する。
- Program Idを書き換える
Anchor.toml
[programs.devnet]
# anchor_counter = "852a53jomx7dGmkpbFPGXNJymRxywo3WsH1vusNASJRr"
# ↓ anchor_counterのProgram Id
anchor_counter = "HWw4L4y47mWmRajHRaKWhfcXxCprzMK47R75PDr7p4DT"
# token-minter = "HfPTAU1bZBHPqcpEGweinAH9zsPafYnnaxk4k5xsTU3M"
# ↓ token_minterのProgram Id
token-minter = "EAharsbLZJUqW2uAL5nsmnVvufTCRpp2ysMs2myQ5wiQ"
programs/anchor-counter/src/lib.rs
# declare_id!("852a53jomx7dGmkpbFPGXNJymRxywo3WsH1vusNASJRr");
declare_id!("HWw4L4y47mWmRajHRaKWhfcXxCprzMK47R75PDr7p4DT");
programs/anchor-minter/src/lib.rs
# declare_id!("HfPTAU1bZBHPqcpEGweinAH9zsPafYnnaxk4k5xsTU3M");
declare_id!("EAharsbLZJUqW2uAL5nsmnVvufTCRpp2ysMs2myQ5wiQ");
- テストする
% anchor test
よくあるエラー
いずれもサンプルをそのままダウンロードして実行すると、Program Idがマッチしないためエラーが出る。MagicBlockがデプロイしたProgramを自身が使おうとしてして、Authorityがないことが原因。
まず自分でProgramsをデプロイして、そのProgram Idを書き換える必要がある。
