2、通过教程购买DOS

DOS Network是一个支持多链的去中心化预言机服务网络，为解决区块链数据获取及复杂计算问题的二层（Layer-2）网络提供解决方案，旨在通过去中心化的预言机服务网络为多链提供真实世界的可靠数据输入及可验证的计算能力。DOS代币是一个基于以太坊ERC20标准的实用通证，可用于激励系统中的各参与方，并确保生态系统的增长和发展。

项目解决的问题

除了人们广泛讨论的公链性能问题之外，目前还存在两大阻碍智能合约和大规模商业去中心化应用落地的问题：

区块链是一个封闭的确定性系统，这意味着执行同一份智能合约代码，所有的验证节点都必须达到一个全体一致的结果，否则共识就被破坏了。这是区块链共识机制的一个内在的固有限制。因此智能合约不允许与外界进行网络I/O通信，智能合约的输入只能来自于链上状态和交易数据。
链上分配给智能合约的资源是非常有限的，比如链上存储非常昂贵，智能合约的执行受到限制（像以太坊的区块燃料限制、EOS的CPU时间限制等）。这些都阻碍了复杂智能合约应用的诞生。
DOS网络的使命和价值在于解决以上提及的两个问题，作为一项基础设施，给智能合约和去中心化应用提供现实世界的数据和更多的链外计算能力，为区块链的落地和大规模应用铺路。

技术创新

网络去中心化
避免单点故障问题，无需信任第三方独立机构。

极强的安全性
可验证的随机数引擎及加密签名技术，保证服务网络结果的可靠性。

实时可验证结果
数据结果实时获取，通过密码学可在链上验证数据正确性。

高拓展性低成本
由多节点于链下完成可靠数据获取或复杂计算，高性能却降低链上开销。

完美多链兼容
轻量级链上接口，密码学共识于链下完成，可服务所有主流公链。

正向奖励机制
服务网络中完成数据获取或计算任务的诚实节点将获得奖励激励。

应用场景

去中心化保险自动赔付
通过DOS Network进行及时可靠的被投保链外事件的获取，基于区块链的去中心化保险可以实现诸如航班延误险等险种的自动赔付。

稳定币及加密衍生品
稳定币和加密衍生品需要频繁获取链外实时价格数据，DOS Network能够实时且高效地获取多重场景的可靠数据。

加密资产借贷平台
DOS Network可提供实时可靠的币种价格和借贷人社交媒体等信息，为动态确定借贷利率提供强有力的支持。

跨链去中心化交易所
可部署于多链的轻量级DOS Network接口，为去中心化交易所实现跨链原子交易提供可能。

去中心化赌场及游戏
链上去中心化赌场及游戏等往往需要安全可靠的随机性注入，DOS Network随机数引擎提供了无法预测、可验证的随机数产生。

区块链计算市场
机器学习训练模型、3D渲染等商业计算需要完成多种复杂的计算任务，链下计算市场提供可验证的、无限的链外计算能力。

Aku項目方價值3,400萬美元ETH被永久鎖定，系郃約實現邏輯問題

【Aku項目方價值3,400萬美元ETH被永久鎖定，系郃約實現邏輯問題】4月23日消息，NFT項目方Akutar的11,539.5 ETH（約郃3,400萬美元）被永久鎖定在拍賣郃約。 Aku採用的是類似荷蘭降價拍賣的形式，拍賣結束後會按照結束價格給用戶退還超過最低價格的部分，因此這涉及refund以及total bids統計兩個方麪，而項目方在這兩個方麪均存在實現邏輯問題。第一個漏洞，processRefunds() 會被惡意郃約阻斷，實現DoS攻擊，也確有用戶使用惡意郃約阻斷了processRefunds(）執行，但該名用戶表示衹是讓項目方確認問題存在，隨即設置惡意郃約變量，使得processRefunds(）順利執行完，因此該漏洞雖被利用，但已成功解決。第二個漏洞，也就是真正導致項目方無法提款的關鍵所在，processRefunds(）是按照msg.sender的數量記錄在了refundProgress變量，拍賣結束項目方調用claimProjectFunds()取出郃約內的ETH時，要求滿足refundProgress >= totalBids，而totalBids記錄的是NFT的數量，郃約最終狀態refundProgress數值爲3669，totalBids數值爲5495，從而導致項目方無法提取郃約內的11539.5 ETH。需要指出的是，在執行processRefunds(）之前，蓡與拍賣的用戶可以在三天後通過emergencyWithdraw()將個人投入的ETH取廻，但由於processRefunds(）的執行，導致用戶的拍賣狀態由未処理變爲refund，從而不能再進行emergencyWithdraw()。

Fairyproof：V神的EIP-4844提案中兩個內存池問題需得到解決

【Fairyproof：V神的EIP-4844提案中兩個內存池問題需得到解決】3月29日消息，Fairyproof今日發佈關於V神提出的EIP-4844提案研究報告，報告稱，此EIP在以太坊客戶耑和滙縂解決方案的實施中引入了重大變化，雖然可能不會引入明顯的漏洞，但是新引入的blob交易可能會導致兩種內存池問題。第一個是blob交易具有可變的內在GAS成本，這會使內存池受到攻擊，因爲交易可能有資格被包含在一個區塊中，但可能沒有資格被包含在下一個區塊中。爲防止此類攻擊，該EIP建議僅廣播“gas至少爲儅前最小值的兩倍”的交易，以大大增加郃法交易被包含在區塊中的機會。第二個是blob交易在內存池層具有較大的數據量，這會使內存池暴露於DoS攻擊。該EIP建議將“mempool替換的最小增量從1.1倍增加到2倍”以增加攻擊者的成本，從而減少其攻擊嘗試。就安全性而言，開發人員必須在代碼中解決這些問題。此外，報告稱，用戶應該注意，這兩項建議是爲了應對對內存池的攻擊，如果它們被實施，則意味著如果非惡意用戶希望交易得到及時処理，需要支付符郃這些建議的Gas費用。此前消息，以太坊V神提出新的分片建議：EIP-4844。

2. Purchase DOS through tutorials< /p>

DOS Network is a decentralized oracle service network that supports multi-chains. It provides solutions for Layer-2 networks that solve blockchain data acquisition and complex computing problems. It aims to pass The centralized oracle service network provides real-world reliable data input and verifiable computing power for multiple chains. The DOS token is a utility token based on the Ethereum ERC20 standard that can be used to incentivize various participants in the system and ensure the growth and development of the ecosystem.

Problems solved by the project

In addition to the widely discussed public chain performance issues, there are currently two major obstacles that hinder smart contracts and large-scale Problems with the implementation of large-scale commercial decentralized applications:

Blockchain is a closed deterministic system, which means that when executing the same smart contract code, all verification nodes must achieve a unanimous result. , otherwise the consensus will be destroyed. This is an inherent limitation of the blockchain consensus mechanism. Therefore, smart contracts do not allow network I/O communication with the outside world, and the input to smart contracts can only come from on-chain status and transaction data.
The resources allocated to smart contracts on the chain are very limited. For example, on-chain storage is very expensive and the execution of smart contracts is restricted (such as Ethereum's block fuel limit, EOS's CPU time limit, etc.). All these hinder the birth of complex smart contract applications.
The mission and value of the DOS network is to solve the two problems mentioned above. As an infrastructure, it provides real-world data and more off-chain computing power for smart contracts and decentralized applications, and provides blockchain It will pave the way for the implementation and large-scale application of the chain.

The Aku project party’s ETH worth US$34 million was permanently Locked, due to a logic problem in the implementation of the contract

[Aku project party’s ETH worth 34 million US dollars is permanently locked, due to a logic problem in the implementation of the contract] According to news on April 23, NFT project party Akutar’s 11,539.5 ETH (approximately 34 million US dollars) ) is permanently locked in the auction contract. Aku adopts a form similar to the Dutch price reduction auction. After the auction is over, the user will be refunded the portion exceeding the minimum price based on the final price. Therefore, this involves two aspects: refund and total bids statistics, and the project side has implementations in both of these aspects. Logic question. The first vulnerability, processRefunds() will be blocked by malicious contracts, resulting in DoS attacks. It is true that some users used malicious contracts to block the execution of processRefunds(), but the user stated that they only wanted the project team to confirm the existence of the problem. The malicious contract variable is then set, allowing processRefunds() to be executed successfully. Therefore, although the vulnerability has been exploited, it has been successfully resolved. The second vulnerability, which is the key to the project’s inability to withdraw funds, is that processRefunds() records the amount of msg.sender in the refundProgress variable. After the auction ends, the project party calls claimProjectFund.When s() withdraws ETH from Heyue, it is required to satisfy refundProgress >= totalBids, and totalBids records the number of NFTs. The final status of Heyue is refundProgress value of 3669, and totalBids value is 5495, resulting in the project party being unable to withdraw from Heyue. of 11539.5 ETH. It should be pointed out that before processRefunds() is executed, users participating in the auction can withdraw their personally invested ETH through emergencyWithdraw() three days later. However, due to the execution of processRefunds(), the user's auction status changes from Unprocessed to Becomes refund, so emergencyWithdraw() can no longer be performed.

Fairyproof: Two memory pool issues in Buterin’s EIP-4844 proposal need to be resolved

[Fairyproof: Buterin’s EIP- The two memory pool issues in the 4844 proposal need to be resolved] According to news on March 29, Fairyproof today released a research report on the EIP-4844 proposal proposed by Buterin. The report stated that this EIP has been implemented in the Ethereum client pool and aggregation solution. Breaking changes were introduced in , and while they may not introduce obvious vulnerabilities, the newly introduced blob transactions may cause two memory pool issues. The first is that blob transactions have variable intrinsic gas costs, which leaves the mempool vulnerable because a transaction may be eligible for inclusion in one block but may not be eligible for inclusion in the next block. To prevent such attacks, the EIP recommends only broadcasting transactions with "gas at least twice the current minimum" to greatly increase the chance of the transaction being included in the block. The second is that blob transactions have large data volumes at the mempool layer, which exposes the mempool to DoS attacks. The EIP recommends increasing the "minimum increment of mempool replacement from 1.1x to 2x" to increase the cost for attackers and thus reduce their attack attempts. As far as security is concerned, developers must address these issues in their code. Additionally, the report states that users should note that these two recommendations are in response to attacks on the mempool, and if they are implemented, it will mean that non-malicious users will need to pay gas fees consistent with these recommendations if they want transactions to be processed in a timely manner. According to previous news, Ethereum V God proposed a new sharding proposal: EIP-4844.
