Swarm激励模型合约

2021-05-12　 Surou　阅读　 OtherChain-新手教程　 0 评论

源代码：https://github.com/ethersphere/swap-swear-and-swindle

Swarm目前只跑在Goerli测试网，核心的合约为ERC20SimpleSwap，源代码在master分支，对于后续功能合约 full Swap, Swear and Swindle相关代码在experimental分支

逻辑简述

目前Swarm的Goerli测试网部署的合约逻辑为
用户通过执行SimpleSwapFactory合约，部署ERC20SimpleSwap合约，并与发行的gBZZ代币交互

用户与Swarm交互

测试用户

0x10210572d6b4924Af7Ef946136295e9b209E1FA0

部署ERC20SimpleSwap合约

用户地址通过执行SimpleSwapFactory合约的deploySimpleSwap方法，完成部署ERC20SimpleSwap合约，通过查看交易的eventlog,部署的Chequebook合约地址为0x68f7ea9f3fae55e3e55fee0f0761b7df570fd212

deploySimpleSwap合约代码

function deploySimpleSwap(address issuer, uint defaultHardDepositTimeoutDuration)
  public returns (address) {
    address contractAddress = address(new ERC20SimpleSwap(issuer, ERC20Address, defaultHardDepositTimeoutDuration));
    deployedContracts[contractAddress] = true;
    emit SimpleSwapDeployed(contractAddress);
    return contractAddress;
  }

deploySimpleSwap执行同时完成了ERC20SimpleSwap的构造初始化

constructor(address _issuer, address _token, uint _defaultHardDepositTimeout) public {
    issuer = _issuer;
    token = ERC20(_token);
    defaultHardDepositTimeout = _defaultHardDepositTimeout;
  }

同时初始化了交互Token gBZZ代币

订金（为支票薄提供资金）

通过执行API进行为支票薄提供资金
http://localhost:1635/chequebook/deposit?amount=1000000000
执行的逻辑为用户地址0x10210572d6b4924af7ef946136295e9b209e1fa0向自己的Chequebook合约地址0x68f7ea9f3fae55e3e55fee0f0761b7df570fd212转对应数量的gBZZ，也可以理解成充值抵押

测试交易

https://goerli.etherscan.io/tx/0x81080bdc2ee4ede8898f003c4b74c9dcabdd6467e443f9ab8669f0c62434aaee

提现

将自己Chequebook合约中的gBZZ体现到用户地址
执行逻辑为执行自己的Chequebook合约地址0x68f7ea9f3fae55e3e55fee0f0761b7df570fd212中的withdraw方法。

合约代码

function withdraw(uint amount) public {
    /* 只有发行人可以做到这一点 */
    require(msg.sender == issuer, "not issuer");
    /* 确保我们不从保证金中提取任何东西 */
    require(amount <= liquidBalance(), "liquidBalance not sufficient");
    require(token.transfer(issuer, amount), "transfer failed");
  }

Swarm Bee 安装与测试

2021-05-10　 Surou　阅读　 Ethereum-新手教程　 0 评论

简介

Swarm是一种去中心化的数据存储和分发技术，可以为下一代不受审查审查的，不可阻挡的无服务器应用程序提供动力。它是最初由以太坊加密货币设想的基于区块链的智能合约的补充，并在Dapp构建难题中提供了大容量存储部分。Swarm是世界计算机的硬盘驱动器。

Bee是Swarm网络的客户端程序

Bee 安装

测试系统 Ubuntu 18.04

安装过程

（推荐）为Bee设置一个外部签名者（即安装bee-clef）
安装Bee应用程序包
用gETH和gBZZ为您的节点提供资金

安装Bee clef软件包

https://docs.ethswarm.org/docs/installation/bee-clef/
https://github.com/ethersphere/bee-clef/releases

wget https://github.com/ethersphere/bee-clef/releases/download/v0.4.10/bee-clef_0.4.10_amd64.deb
sudo dpkg -i bee-clef_0.4.10_amd64.deb

配置Bee-clef

cd /etc/bee-clef/

在正常/默认软件包安装下，开始使用bee-clef不需要进行任何配置更改。

检查Bee-clef是否安装正确

一旦安装了Clef，它将开始作为服务运行。
要检查Clef是否运行正常，我们可以使用systemctl

systemctl status bee-clef

surou@bcskill:/etc/bee-clef$ systemctl status bee-clef
● bee-clef.service - Bee Clef
   Loaded: loaded (/lib/systemd/system/bee-clef.service; enabled; vendor preset: enabled)

           └─22365 tee /var/lib/bee-clef/stdout

查看服务日志

sudo journalctl -f -u bee-clef.service

Bee-clef第一次启动时，您应该看到与以下内容非常相似的内容：

可以安全地忽略此行，无需执行任何操作：

{"jsonrpc":"2.0","method":"ui_onSignerStartup","params":[{"info":{"extapi_http":"n/a","extapi_ipc":"/var/lib/bee-clef/clef.ipc","extapi_version":"6.1.0","intapi_version":"7.0.1"}}]}

一旦bee开始与bee-clef您进行交互，您应该开始看到日志消息，对于定期活动和连接的节点，它们将每隔几秒钟出现一次：

...

数据位置

关键材料和其他数据存储在 /var/lib/bee-clef/
蜜蜂可以通过多种方式与养蜂人交流。如果通过软件包安装，则默认方式将使用进程间通信（IPC）文件。这是Bee-clef在启动时创建的特殊文件，Bee将使用该文件来回发送请求。Bee-clef服务运行时，您会注意到/var/lib/bee-clef/clef.ipc已创建一个文件。

bee节点地址私钥

文件默认创建在
keystore: /var/lib/bee-clef/keystore/
password: /var/lib/bee-clef/password
直接导入MetaMask即可

手动安装

要手动安装Clef，请首先从以太坊的Geth＆Tools下载页面中检索相关的Clef二进制文件，或直接从源代码进行构建。

由于Bee需要Clef自动签署许多交易，因此我们必须将Clef作为具有宽松权限和规则集的服务运行。为确保Clef仅签署来自Bee的交易，我们必须clef.ipc通过创建Bee用户并设置权限来保护文件，以便该用户只能使用ipc套接字。

另外，Clef需要Bee的支票簿交互的交易签名。

可以在Bee-clef存储库中找到自动执行初始化后权限更改（包括Clef配置）的Shell脚本clef-service，以及4byte.json事务签名文件和rules.js文件。

最后，一旦Clef运行，只需将Bee节点配置为启用Clef使用，--clef-signer-enable然后使用将Bee指向正确的ipc套接字即可--clef-signer-endpoint。

安装Bee

wget https://github.com/ethersphere/bee/releases/download/v0.5.3/bee_0.5.3_amd64.deb
sudo dpkg -i bee_0.5.3_amd64.deb

SWAP区块链端点

您的Bee节点必须有权访问以太坊区块链，以便它可以交互并部署您的支票簿合同。您可以运行自己的Goerli节点，也可以使用rpc.slock.it/goerli 或 Infura之类的提供程序。

默认情况下，Bee希望在本地有Goerli节点http://localhost:8545
要改用提供程序，只需--swap-endpoint在您的配置文件中更改即可。

切换登录用户

由于程序目录的权限账户默认初始化为bee

surou@bcskill:/var/lib$ ll
total 176
drwxr-x---  4 bee       bee       4096 May 10 11:58 bee/
drwxr-x---  4 bee-clef  bee-clef  4096 May 10 10:34 bee-clef/

所以需要切换下登陆账户

su bee

修改swap-endpoint配置

sudo vi /etc/bee/bee.yaml
sudo systemctl restart bee

...
swap-endpoint: https://rpc.slock.it/goerli
...

激活节点

启用了SWAP的Bee节点需要gETH和gBZZ才能开始操作。

cannot continue until there is sufficient ETH (for Gas) and at least 10 BZZ available on 10210572d6b4924af7ef946136295e9b209e1fa0

当前版本的Swarm激励措施正在以太坊Goerli测试网上运行。要获取免费的gBZZ令牌，请访问Bzzaar，然后执行以下步骤！

1. 查看Bee节点地址

sudo bee-get-addr

Please make sure there is sufficient ETH and BZZ available on the node's Ethereum address: 10210572d6b4924af7ef946136295e9b209e1fa0.

You can get both Goerli ETH and Goerli BZZ via the Bzzaar at https://bzz.ethswarm.org/?transaction=buy&amount=10&slippage=30&receiver=0x10210572d6b4924af7ef946136295e9b209e1fa0

或者通过API获取

curl -s localhost:1635/addresses | jq .ethereum

得到0x10210572d6b4924af7ef946136295e9b209e1fa0
确认下与前面Bee-clef创建的keystore中的地址一致

2. 获取gBZZ

通过上面日志可以获取到

https://bzz.ethswarm.org/?transaction=buy&amount=10&slippage=30&receiver=0x10210572d6b4924af7ef946136295e9b209e1fa0

3. 打开此连接，然后链接`Metamask`扩展

4. 点击下面的`GET G-ETH`

5. 等待Goerli ETH到达您的钱包

官方将向您连接的钱包和Bee的钱包中发送少量gETH（gETH 就是 goerli的系统测试代币）！
这可能需要几分钟，请检查Etherscan上的水龙头地址，然后查找到您的地址的交易。
交易完成后，您可能需要重新连接钱包以查看余额增加。

也可以访问https://faucet.ethswarm.org/水龙头获取
如果上面的都不举，就用 https://faucet.goerli.mudit.blog/
还有 https://gitter.im/goerli/testnet?at=5f7f1d756e0eb84469728b8b

6. 兑换

一旦有了余额，在该gBZZ字段中至少输入10 ，您甚至可能有足够的gETH来购买更多！这是另一项区块链交易，只需几分钟即可查看Metamask，以查看交易进展如何。

7. 兑换完成

完成交易后，您的Bee节点应该是一些新鲜出炉的gBZZ的骄傲拥有者！

8. 检查节点

检查Bee节点，它现在应该开始部署您的支票簿合同。如果您的节点已停止轮询更新，则现在可能需要重新启动它。

一旦您的Bee节点完全加载了gBZZ，我们现在就可以观看日志，并观看Bee自动部署支票簿并进行初始存入的情况。

切勿将您的Debug API暴露在公共互联网上，请确保使用防火墙或绑定到localhost，如下面的示例所示。

上传和下载文件

Bee提供了一种方便的方式将您的数据上传到Swarm。一旦您的数据被上传，它将被遍布全球的p2p节点网络分发和存储，并可以从Swarm的Web网关中获取。

快速上传

Bee节点运行后，将启用HTTP API与您进行交互。命令行实用程序curl是与Bee节点的API交互的好方法。
首先，让我们检查一下API是否按预期运行...

curl http://localhost:1633

Ethereum Swarm Bee

运行后，可以通过files向Bee API的端点发出HTTP POST请求来上传文件。

curl -F file=@bee.jpg http://localhost:1633/files

我们还可以在Content-Type标头中传递适当的mime类型，并在name查询参数中传递文件名，以便Web浏览器和其他应用程序可以正确处理该文件。

curl --data-binary @bee.jpg  -H "Content-Type: video/jpg" "http://localhost:1633/files?name=bee.jpg"

{"reference":"042d4fe94b946e2cb51196a8c136b8cc335156525bf1ad7e86356c2402291dd4"}

在Swarm中，每条数据都有一个唯一的地址，该地址是一个唯一且可复制的加密哈希摘要。如果您上载相同的文件两次，您将始终收到相同的哈希值。这使得在Swarm中处理数据变得超级安全！

如果您要上传大文件，则在处理上传到网络中时，跟踪上传状态非常有用。转至“高级用法”部分，以了解如何跟踪您的上传状态。

文件与网络完全同步后，您将可以关闭计算机，其他节点将接管您的数据工作！

下载文件

将文件上传到Swarm后，可以使用简单的HTTP GET请求对其进行检索。
将哈希的最后一部分替换为对您自己的数据的引用。

curl -OJ http://localhost:1633/files/042d4fe94b946e2cb51196a8c136b8cc335156525bf1ad7e86356c2402291dd4

您甚至可以简单地导航到浏览器中的URL
http://localhost:1633/files/042d4fe94b946e2cb51196a8c136b8cc335156525bf1ad7e86356c2402291dd4

公共网关

要与尚未运行Bee节点的人共享文件，只需将链接中的主机更改为我们的公共网关之一。将链接发送给您的朋友，他们也可以下载文件！
https://gateway.ethswarm.org/files/042d4fe94b946e2cb51196a8c136b8cc335156525bf1ad7e86356c2402291dd4

高级用法

PSS消息传递

跟踪上传状态

https://docs.ethswarm.org/docs/advanced/tags

坚持不懈

每个Bee节点均配置为在计算机硬盘驱动器上保留一定数量的内存，以在Swarm网络中其他节点的职责范围内存储和提供服务。一旦分配的空间已满，每个Bee节点将删除较旧的块，以便为较新的块腾出空间，因为它们是由网络上载的。

每次访问块时，它都会移回到删除队列的末尾，以便定期访问的内容在网络中保持活动状态，并且不会被节点的垃圾回收例程删除。

SWAP带宽核算

Swarm的基础是一组会计协议，这些协议已在5年的研发过程中开发并原型化。您的Beta Bee节点包含功能，使其能够跟踪与所有对等节点的带宽交换，使用生活在与EVM兼容的区块链上的智能合约来进行签发和缓存检查。目前，我们正在使用Goerli测试网进行测试。我们希望您能参与其中，帮助我们尝试这些激励措施，甚至可以赚取一些gBZZ！
