motoko demo (15 min)

1. dfx new demo_mo
2. delete asset & motify config dfx.json
3. add code and explain logic and related libraries
4. new a canister in IC, add config canister_ids.json
5. deploy on IC
6. get result in explore, https://fesla-yiaaa-aaaah-aa4na-cai.raw.ic0.app/, dfx query

   dfx canister --network ic --no-wallet call demo_mo allBalances --query
   
   dfx identity use alice
   dfx identity get-principal
   ktfx3-4dj7o-f4lqf-gab56-fgkuw-aagt6-jzpkd-o7xzp-f6a3p-nm6wl-wae
   
   dfx identity use bob
   dfx identity get-principal
   yd5hv-nayum-igkpt-jtrhr-aqfqq-pfkxn-fyxvh-yryn3-rez4o-p6vks-hqe
   
   dfx identity use icp
   dfx identity get-principal
   yhy6j-huy54-mkzda-m26hc-yklb3-dzz4l-i2ykq-kr7tx-dhxyf-v2c2g-tae

7. dfx call (userA -> alice 100, alice -> bob 50, bob -> userA 200 (failed))

   dfx canister --network ic --no-wallet call demo_mo transfer '(principal "ktfx3-4dj7o-f4lqf-gab56-fgkuw-aagt6-jzpkd-o7xzp-f6a3p-nm6wl-wae", 100)'
   dfx canister --network ic --no-wallet call demo_mo transfer '(principal "yd5hv-nayum-igkpt-jtrhr-aqfqq-pfkxn-fyxvh-yryn3-rez4o-p6vks-hqe", 50)'
   dfx canister --network ic --no-wallet call demo_mo transfer '(principal "yhy6j-huy54-mkzda-m26hc-yklb3-dzz4l-i2ykq-kr7tx-dhxyf-v2c2g-tae", 200)

8. get result in explore, dfx query

   dfx canister --network ic --no-wallet call demo_mo allBalances --query

9. delete allBalance, upgrade, get result in explore, https://b4e6x-kaaaa-aaaah-aa4uq-cai.raw.ic0.app/

sudo dfx build --network ic
sudo dfx canister --no-wallet --network ic install demo_mo -m=upgrade 

rust demo (5 min)

1. cargo new demo_rs
2. add config dfx.json
3. add code and explain logic and related libraries
4. new a canister in IC, add config canister_ids.json
5. deploy on IC

   dfx canister --no-wallet --network ic install demo_rs

6. get result in explore, dfx query

   dfx canister --network ic --no-wallet call demo_rs transfer '(principal "ktfx3-4dj7o-f4lqf-gab56-fgkuw-aagt6-jzpkd-o7xzp-f6a3p-nm6wl-wae", 100)'
