ADAO
A new SRML-based Substrate node, ready for hacking.
With developing.....
团队名称:Apollo
项目名称:ADAO
ADAO是基于Substrate Runtime实现的一个社区驱动、DAO治理的广告系统。采用哈博格税模型实现广告牌的价值发现和定价。赞助商或广告主需要购买广告牌的使用权,并向DAO支付哈博格税,通过市场博弈来实现广告牌的合理定价。而DAO组织可以使用税收收入,通过智能合约提案治理的方式对广告系统的条款(如广告内容筛选等)进行管理。
已实现了一个在线广告牌,更多功能开发中。。。
目前可以将页面上的多个展示位卖出,功能包括:
- 创建广告位(banner)
- 设定拍卖状态(24*600个块后结束,最终状态:有效成交和流拍需要一笔交易触发)
- 出价竞拍
- 竞拍成功后,可以上传展示图片url到广告位
公开函数
- create_banner (创建广告位)
- set_image_url (广告位所有者修改广告位图片)
- auction_banner(广告位所有者创建拍卖)
- bid(竞拍)
数据结构
* Banner
* id
* name
* image_url
* desc
* current_price
* current_bidder
* can_bid
* bid_end_height
模块Storage:
Banners get(banner): map T::Hash => Banner<T::Hash, T::Balance, T::AccountId, T::BlockNumber>;
BannerOwner get(owner_of): map T::Hash => Option<T::AccountId>;
AllBannersArray get(banner_by_index): map u64 => T::Hash;
AllBannersCount get(all_banners_count): u64;
AllBannersIndex: map T::Hash => u64;
OwnedBannersArray get(banner_of_owner_by_index): map (T::AccountId, u64) => T::Hash;
OwnedBannersCount get(owned_banner_count): map T::AccountId => u64;
OwnedBannersIndex: map T::Hash => u64;
用map模拟全部banners数组,某地址所有banners数组的实现。
模块Event:
* CreateBanner(AccountId, Hash)
* StartAuction(AccountId, Hash, Balance)
* Bid(AccountId, Hash, Balance)
* Transferred(AccountId, AccountId, Hash)
* Deal(AccountId, Hash, Balance)
* Abort(AccountId, Hash)
根据交易类型及上述event类型可以重现某个banner的所有拍卖流程
Building
Install Rust:
curl https://sh.rustup.rs -sSf | sh
Install required tools:
./scripts/init.sh
Build the WebAssembly binary:
./scripts/build.sh
Build all native code:
cargo build
Run
You can start a development chain with:
cargo run -- --dev
Detailed logs may be shown by running the node with the following environment variables set: RUST_LOG=debug RUST_BACKTRACE=1 cargo run -- --dev
.
If you want to see the multi-node consensus algorithm in action locally, then you can create a local testnet with two validator nodes for Alice and Bob, who are the initial authorities of the genesis chain that have been endowed with testnet units. Give each node a name and expose them so they are listed on the Polkadot telemetry site. You'll need two terminal windows open.
We'll start Alice's substrate node first on default TCP port 30333 with her chain database stored locally at /tmp/alice
. The bootnode ID of her node is QmQZ8TjTqeDj3ciwr93EJ95hxfDsb9pEYDizUAbWpigtQN
, which is generated from the --node-key
value that we specify below:
cargo run -- \
--base-path /tmp/alice \
--chain=local \
--alice \
--node-key 0000000000000000000000000000000000000000000000000000000000000001 \
--telemetry-url ws://telemetry.polkadot.io:1024 \
--validator
In the second terminal, we'll start Bob's substrate node on a different TCP port of 30334, and with his chain database stored locally at /tmp/bob
. We'll specify a value for the --bootnodes
option that will connect his node to Alice's bootnode ID on TCP port 30333:
cargo run -- \
--base-path /tmp/bob \
--bootnodes /ip4/127.0.0.1/tcp/30333/p2p/QmQZ8TjTqeDj3ciwr93EJ95hxfDsb9pEYDizUAbWpigtQN \
--chain=local \
--bob \
--port 30334 \
--telemetry-url ws://telemetry.polkadot.io:1024 \
--validator
Additional CLI usage options are available and may be shown by running cargo run -- --help
