挑战者大7_合约maker是什么意思"

一:Logistics Company 功能介绍

  • 所有人都可以创建独属于自己的物流公司,按照每百克的价格定价(不满100g的将按照100g计算),当然,公司所有者也可以注销这所公司,但前提是处理完所有的业务。
  • 所有人都可以是顾客,提供将要运输的物品信息(主要是重量)进行下单,同时支付费用。
  • 类似于现今的各大消费平台,支付的费用不会直接抵达公司的账户下,而是存储在平台的某个地方(在这里,就是 S u i \mathit {Sui} Sui 链上的某个对象中,不提供对该对象内的金额直接提现的功能),只有用户凭借快递单确认收货,或者超过15个周期由公司进行确认收货操作后,对应的款项才会打入公司的账户。
  • 只有进入公司账户的收益额,管理者才能够将其提现到自己的钱包,当然,为了该平台的可持续发展,每一笔提现,需要支付给平台创始人 1 % \text 1\% 1% 的抽成。
  • 平台创始人可以通过对抽成得到的收益进行提现。
  • 下单后不超过3个周期,顾客可以凭快递单进行退款操作,金额将原封不动退入消费者账户钱包。

二:结构定义

2.1 平台创始人

需要一个Balance<SUI>来存储提成,所以该对象需要共享可变。
但是提现操作只能是创始人自己,因此通过 O n e \mathit {One} One T i m e \mathit {Time} Time W i t n e s s \mathit {Witness} Witness 来创建一个Publisher在后续调用时表明身份。

// Define ADMIN(one time witness) struct struct ADMIN has drop {} // Define Admin struct struct Admin has key { id: UID, balance: Balance<SUI>, } 

2.2 公司

公司的各项信息都应该透明,尤其是价格方面,所以该对象也应该是共享甚至是可变的,因为当顾客下单后,需要将物品相关信息暂存入公司。
类似的,收益提现以及由公司确认收货操作都需要公司管理者才有权限,因此再创建一个所有者为个人的凭证对象。

// Define CompanyCap struct struct CompanyCap has key { id: UID, } // Define Company struct struct Company has key { id: UID, name: String, price_per_hundred_grams: u64, waiting_for_receipt: LinkedTable<ID, ItemInfo>, can_be_cashed: Balance<SUI>, all_profit: u64, } 

其中用到了LinkedTable,这是一个通过 K e y \mathit {Key} Key V a l u e \mathit {Value} Value 存储的自带的数据结构,拥有头插,尾插,从头部取出,从尾部取出等功能,用来维护待确认收货的物流信息比较合适,具体可以点击查看源码。

2.3 物流

顾客下单后会得到与公司相对应的快递单(通过公司的 I D \mathit {ID} ID 进行对应),该快递单不对外公开,仅下单的顾客拥有。
同时生成相对应的信息,包括下单时期以及金额等。

// Define TransportItem struct struct TransportItem has key { id: UID, logistics_company: String, company_id: ID, weight: u64, price: u64, } // Define ItemInfo struct struct ItemInfo has store { epoch: u64, transport_price: Balance<SUI>, } 

三:功能实现

3.1 平台创始人

3.1.1 发布时初始化

在发布该合约的时候自动调用的init函数当中,通过只能在这里使用的 O n e \mathit {One} One T i m e \mathit {Time} Time W i t n e s s \mathit {Witness} Witness 来创建Publisher,并将其拥有权递交给发布者。
同时,在该函数当中,创建一个共享可变的Admin,用作各大公司提现时获取提成的账户。

// Function to init the publisher and admin fun init(otw: ADMIN, ctx: &mut TxContext) { // create Publisher and transfer it to the sender package::claim_and_keep(otw, ctx); // create Admin and share it with all users transfer::share_object(Admin { id: object::new(ctx), balance: balance::zero(), }); } 

3.1.2 提现

通过Publisher确认身份,当Admin当中的抽成大于零的时候可以对其进行提现(将 S U I \mathit {SUI} SUI b a l a n c e \mathit {balance} balance 包装成 C o i n \mathit {Coin} Coin 发送给平台创始人)。

// Function to withdraw(only the publisher can withdraw) public entry fun withdraw(_publisher: &Publisher, admin: &mut Admin, ctx: &mut TxContext) { // get the value amount let amount = balance::value(&admin.balance); // it's necessary to make sure the amount > 0 assert!(amount > 0, ERROR_NOT_BALANCE); // transfer the coin with the all balance to the sender transfer::public_transfer(coin::take(&mut admin.balance, amount, ctx), tx_context::sender(ctx)); } 

3.2 公司

3.2.1 创建公司

不仅要根据信息创建公开的Company,还需要创建仅创建者持有的CompanyCap用作后续的身份凭证(在这里的功能效果类似于上面的Publisher)。

// Function to create company public entry fun create_company(name: String, price_per_hundred_grams: u64, ctx: &mut TxContext) { // create CompanyCap and transfer it to the sender // this is a testament to the company's managers transfer::transfer(CompanyCap { id: object::new(ctx), }, tx_context::sender(ctx)); // create Company and share it with all users transfer::share_object(Company { id: object::new(ctx), name, price_per_hundred_grams, waiting_for_receipt: linked_table::new<ID, ItemInfo>(ctx), can_be_cashed: balance::zero(), all_profit: 0, }); } 

3.2.2 确认收货

只有下单后超过 15 \text {15} 15 个周期的货物,公司有权进行确认收货操作。
在此之前,我们先来明确一个隐性的条件,那就是每当有顾客下单,对应的信息被push_backlinked_table,其中所存储的epoch是下单时的值,而下单这个操作本身是有序的,时间也不可能乱序,所以在link_table中所存储的信息,从前到后的epoch理论上来说也应该是非严格递增的。
基于上述理论,在该函数当中,可以通过从前到后的循环进行,直到linked_table为空或者front不满足epoch条件时跳出循环。
为了更清晰明了地演示一步步地取值过程,这里采用了loop无限循环(要注意其跳出循环的条件,因为合约发布时并不能明确这是否是正确的),如果对取值以及数据之间调用比较熟悉的,可以直接将跳出循环的条件写在一起当做判决用while
当然,想要进行这一操作,需要你拥有对应公司的管理员权限,也就是CompanyCap

// Function to unconfirmed receipt items with confirmation epoch greater than 15 // Company managers can only confirm the company's transport items public entry fun confirm_items(_company_cap: &CompanyCap, company: &mut Company, ctx: &mut TxContext) { // get the now epoch let now_epoch = tx_context::epoch(ctx); // to be confirmed list let items = &mut company.waiting_for_receipt; // theoretically, the linked table is sorted according to epoch // because when user call function, linked_table push_back, this is orderly in itself loop { // items need to be not empty if (linked_table::is_empty(items)) break; // linked_table::front -> &Option<Element> // option::borrow -> &Element // in this module, Element is ID let key = *option::borrow(linked_table::front(items)); // linked_table::borrow -> &Value // in this module, Value is ItemInfo let transport_epoch = linked_table::borrow(items, key).epoch; // the front item's epoch is longer than 15 if (transport_epoch + 15 >= now_epoch) break; // pop the front and get the ItemInfo let (_, item_info) = linked_table::pop_front(items); // destroy ItemInfo and get the price let ItemInfo { epoch: _, transport_price, } = item_info; // add to the all_profit company.all_profit = company.all_profit + balance::value(&transport_price); // add the profit balance::join(&mut company.can_be_cashed, transport_price); }; } 

3.2.3 提现

需要管理员权限CompanyCap才可调用,这里的关键是需要取出 1 % \text 1\% 1% 存入Admin,由于 M o v e \mathit {Move} Move 语言目前对浮点数的支持有限,所以这里平台创始人吃点亏,只抽取 ⌊ p r o f i t 100 ⌋ \lfloor \frac{\mathit{profit}}{\text{100}} \rfloor 100profit

// Function to cash public entry fun cash(_company_cap: &CompanyCap, admin: &mut Admin, company: &mut Company, ctx: &mut TxContext) { // get the amount of balance let can_be_cashed = &mut company.can_be_cashed; let amount = balance::value(can_be_cashed); // check the amount assert!(amount > 0, ERROR_NOT_BALANCE); // admin profit: 1% of the balance let admin_profit = balance::split(can_be_cashed, amount / 100); // add to the admin balance let admin_balance = admin::get_balance_mut(admin); balance::join(admin_balance, admin_profit); // the remaining amount belongs to the company amount = balance::value(can_be_cashed); transfer::public_transfer(coin::take(can_be_cashed, amount, ctx), tx_context::sender(ctx)); } 

3.2.4 注销公司

解构创建的与公司有关的对象,也就是CompanyCapCompany,注意,后者内部的LinkedTableBalance都需要手动摧毁,如果其中不为空,则会报错,同时恢复到该交易之前的状态。

// Function to destroy company public entry fun destroy_company(company_cap: CompanyCap, company: Company) { // deconstruct the CompanyCap let CompanyCap {id} = company_cap; // delete the id object::delete(id); // deconstruct the Company let Company { id, name: _, price_per_hundred_grams: _, waiting_for_receipt, can_be_cashed, all_profit: _, } = company; // delete the id object::delete(id); // destroy linked_table linked_table::destroy_empty(waiting_for_receipt); // destroy balance balance::destroy_zero(can_be_cashed); } 

3.3 物流

3.3.1 创建(下单)

选择公司,提供物品重量,支付对应的金额(多退少报错),顾客得到仅自己可见的快递单,而对应的信息则存储入Company当中的LinkedTable,其中作为 K e y \mathit {Key} Key I D \mathit {ID} ID 取自对应的快递单,也就是TransportItem

// Function to create transport item public entry fun create_item(company: &mut Company, weight: u64, sui: Coin<SUI>, ctx: &mut TxContext) { // if the weight is less than 100g, it will be calculated as 100g // in other words: weight / 100 rounded up multiply by price_per_hundred_grams let price = (weight + 99) / 100 * company.price_per_hundred_grams; // check enough price assert!(coin::value(&sui) >= price, ERROR_NOT_ENOUGH_COIN); // split the right price let transport_price = coin::split(&mut sui, price, ctx); // destroy or transfer the remaining coin to the owner if (coin::value(&sui) == 0) { coin::destroy_zero(sui); } else { transfer::public_transfer(sui, tx_context::sender(ctx)); }; // create TransportItem let transport_item = TransportItem { id: object::new(ctx), logistics_company: company.name, company_id: object::id(company), // corresponding company ID weight, price, }; // get the ID through transport_item to achieve a one-on-one relationship let id = object::id(&transport_item); // create ItemInfo let item_infomation = ItemInfo { epoch: tx_context::epoch(ctx), transport_price: coin::into_balance(transport_price), }; // transfer the credentials to the user transfer::transfer(transport_item, tx_context::sender(ctx)); // store the item_info to the company linked_table::push_back(&mut company.waiting_for_receipt, id, item_infomation); } 

3.3.2 退款

下单后不超过 3 \text 3 3 个周期的订单才可以退款,而且TransportItem当中的company_id必须与退款公司相一致,当然,该订单必须存在且未被确认收货。

// Function to refunds if no more than 3 epoch public entry fun refunds(transport_item: TransportItem, company: &mut Company, ctx: &mut TxContext) { // check whether it corresponds to the company assert!(transport_item.company_id == object::id(company), ERROR_NOT_ORDERED_COMPANY); // get waiting_for_receipt let waiting_for_receipt = &mut company.waiting_for_receipt; // get the ID through transport_item let id_key = object::id(&transport_item); // determine whether it is the correct item or whether it is receipted assert!(linked_table::contains(waiting_for_receipt, id_key), ERROR_NOT_ITEM_OR_RECEIPTED); // must not exceed 3 epochs assert!(linked_table::borrow(waiting_for_receipt, id_key).epoch + 3 >= tx_context::epoch(ctx), ERROR_NOT_REFUNDS); // deconstruct the ItemInfo let ItemInfo { epoch: _, transport_price, } = linked_table::remove(waiting_for_receipt, id_key); // get the balance amount let amount = balance::value(&transport_price); // refunds transfer::public_transfer(coin::take(&mut transport_price, amount, ctx), tx_context::sender(ctx)); // destroy the zero balance balance::destroy_zero(transport_price); // destroy TransportItem destroy_transport_item(transport_item); } 

3.3.3 确认收货

通过TransportItem到对应的Company确认收货,成功后快递单将被销毁,而对应的款项将被转移到公司的账户。
如果该信息已经超过了 15 \text {15} 15 个周期且物流公司确认收货了,那么此函数仅执行销毁快递单的操作。

// Function to confirm receipt by correct TransportItem public entry fun confirm_receipt(transport_item: TransportItem, company: &mut Company) { // check whether it corresponds to the company assert!(transport_item.company_id == object::id(company), ERROR_NOT_ORDERED_COMPANY); // get waiting_for_receipt let waiting_for_receipt = &mut company.waiting_for_receipt; // get the ID through transport_item let id_key = object::id(&transport_item); // determine whether it is the correct item or whether it is receipted if (linked_table::contains(waiting_for_receipt, id_key)) { // deconstruct the ItemInfo let ItemInfo { epoch: _, transport_price, } = linked_table::remove(waiting_for_receipt, id_key); // add to the all_profit company.all_profit = company.all_profit + balance::value(&transport_price); // add the profit balance::join(&mut company.can_be_cashed, transport_price); }; // destroy TransportItem destroy_transport_item(transport_item); }
