0x decentralized exchange had to suspend all of trading services after discovering a critical security flaw that might pose risk to it’s users.

This vulnerability would allow an attacker to fill certain orders with invalid signatures. This vulnerability does not effect the ZRX token contract; your digital assets are safe.” However, as a precaution, 0x shut down the Exchange contract and Asset Proxy contracts responsible for performing asset transfers on the 0x protocol.

Will Warren , 0x CEO

This vulnerability was discovered by 3rd party security researcher Sam Sun , who was nice rnough to disclose it’s details to 0X exchange team.

What Is 0x?

0x is an open protocol for exchanging ERC-20 tokens on the Ethereum blockchain using an off-chain order relay and on-chain settlement strategy. It’s native token, ZRX, is used for trading fees and ultimately, governance. 0x is a public system of smart contracts with a formalized message schema that outlines how an order should be structured. 0x is not a decentralized exchange itself3, but rather democratizes the process of building a decentralized exchange. The founders believe the true value lies in equipping teams with the tools, libraries and smart contracts needed to build for-profit relayers (0x’s version of DEXs) and creating a global pool of shared liquidity. Thus, 0x is to relayers what Ethereum is to dApps – a platform to build upon.

Major Differences Between Binance Smart Chain and Ethereum

Binance Smart Chain (BSC) is a blockchain network developed by Binance, one of the largest cryptocurrency exchanges in the world. It is a high-performance blockchain that is designed to provide a fast, secure, and low-cost environment for the development and execution of decentralized applications (dApps) and smart contracts.

Binance Smart Chain (BSC) and Ethereum are both blockchain networks that support the development and execution of decentralized applications (dApps) and smart contracts. However, there are several key differences between the two that are worth highlighting.

The supported programming languages

One important difference between the two is the programming languages they support. Binance Smart Chain supports multiple programming languages, including Ethereum’s Solidity, which is used to write smart contracts on the Ethereum blockchain.

This allows developers to easily migrate their dApps from Ethereum to Binance Smart Chain. Binance Smart Chain also support GO, Java, Javascript, C++, C#, Python, and Swift.

Token swap feature

Binance Smart Chain has a built-in token swap feature that allows users to exchange tokens directly on the blockchain, without the need for a centralized exchange. This is a significant advantage over Ethereum, where users typically need to go through a centralized exchange to buy and sell tokens.

Binance Smart Chain is a layer 2 scaling

Another key difference is that Binance Smart Chain is a layer 2 scaling solution built on top of the Ethereum blockchain, and it’s also a DeFi focused blockchain. Ethereum, on the other hand, is a standalone blockchain that has been around for much longer and has a much larger ecosystem of dApps and tokens.

BSC Tokenomics

The Binance Smart Chain (BSC) is similar to the Binance Chain in that it uses the same token universe for both BNB and BEP2 tokens. BNB is the native token for BSC and has multiple uses, including paying for “gas” when deploying smart contracts, staking and rewards, and performing operations across chains such as transferring token assets between the Binance Chain and Binance Smart Chain.

The current circulating supply of BNB is 144,406,561 tokens, and the maximum supply is set at 176,406,561 tokens. It’s worth noting that Binance Smart Chain is also compatible with Ethereum and thus supports ERC20 tokens.

Conclusion

Binance Smart Chain and Ethereum are both blockchain networks that support the development and execution of dApps and smart contracts. However, they have different consensus mechanisms, programming languages, token swap features, and different ecosystem. Each blockchain has its own advantages and disadvantages, and developers and users should carefully consider which one is the best fit for their needs.

While Binance Smart Chain is growing rapidly and has a lot of potential, Ethereum has a proven track record and a much larger community of developers and users.

Why Most Cryptocurrency Exchanges ask For KYC

Know-Your-Customer (KYC) is a process that most cryptocurrency exchanges require their customers to go through in order to use their platform. This process involves providing personal information such as name, address, and government-issued identification number to the exchange. While it may be seen as an inconvenience by some, but KYC is an important aspect of maintaining the security and integrity of the cryptocurrency ecosystem.

1- Legal compliance

Legal compliance is a key reason why online cryptocurrency exchanges ask for know-your-customer (KYC) information. Anti-money laundering (AML) regulations, which are designed to prevent money laundering and other financial crimes, require financial institutions to verify the identity of their customers and to monitor transactions for suspicious activity. By collecting KYC information from their customers, online cryptocurrency exchanges can demonstrate that they are taking steps to comply with these regulations and to prevent financial crime.

When it comes to legal compliance, online cryptocurrency exchanges must comply with AML regulations and other laws applicable to their jurisdiction. These regulations are usually set by government bodies such as the Financial Action Task Force (FATF) and the US Financial Crimes Enforcement Network (FinCEN). These regulations require exchanges to implement certain measures such as KYC, transaction monitoring, and suspicious activity reporting.

KYC is a crucial part of AML compliance, as it helps exchanges to identify and verify the identity of their customers. This includes collecting personal information such as name, address, and government-issued identification number. Additionally, exchanges may also be required to collect information about the source of funds and the intended use of the funds. By collecting this information, exchanges can ensure that they are not doing business with individuals or entities that are involved in illegal activities such as money laundering or terrorism financing.

Furthermore, online cryptocurrency exchanges are also required to comply with other laws such as the USA PATRIOT Act, which requires financial institutions to implement measures to prevent money laundering and the financing of terrorism. By complying with these regulations, exchanges can ensure that they are operating within the law, and they can avoid penalties and fines.

2- Risk Management

Risk management is another important reason why most cryptocurrency exchanges ask for know-your-customer (KYC) information. By collecting and verifying the identity of their customers through the KYC process, exchanges can mitigate the risk of fraudulent activities and protect themselves and their customers from financial crimes.

One of the main risks that cryptocurrency exchanges face is money laundering. Money laundering is the process of disguising the proceeds of illegal activities as legitimate funds. By collecting and verifying the identity of their customers through the KYC process, exchanges can ensure that they are not doing business with individuals or entities that are involved in money laundering.

Another risk that cryptocurrency exchanges face is terrorist financing. Terrorist financing is the provision or collection of funds with the intention that they should be used to carry out terrorist acts. By collecting and verifying the identity of their customers through the KYC process, exchanges can ensure that they are not doing business with individuals or entities that are involved in terrorist financing.

Identity theft is also a risk that cryptocurrency exchanges face. By collecting and verifying the identity of their customers through the KYC process, exchanges can ensure that they are not doing business with individuals or entities that have stolen identities.

3- Protecting The Integrity of The Cryptocurrency Ecosystem

AML regulations help to prevent the use of cryptocurrencies for illegal activities, and by implementing KYC, online exchanges can help to protect the integrity of the cryptocurrency ecosystem as a whole.

4- Avoiding Sanctions

Avoiding sanctions is another reason why most cryptocurrency exchanges ask for know-your-customer (KYC) information. Sanctions are economic or financial restrictions imposed by governments or international organizations to achieve foreign policy or national security objectives. By collecting and verifying the identity of their customers through the KYC process, exchanges can ensure that they are not doing business with individuals or entities that are subject to sanctions.

When it comes to sanctions, cryptocurrency exchanges must comply with the regulations set by government bodies such as the Office of Foreign Assets Control (OFAC) in the United States, and similar organizations in other countries. These regulations prohibit transactions with individuals or entities that are designated as Specially Designated Nationals (SDN) or are otherwise blocked by sanctions.

KYC is a crucial part of sanctions compliance, as it helps exchanges to identify and verify the identity of their customers. This includes collecting personal information such as name, address, and government-issued identification number. Additionally, exchanges may also be required to collect information about the source of funds and the intended use of the funds. By collecting this information, exchanges can ensure that they are not doing business with individuals or entities that are subject to sanctions.

Furthermore, online cryptocurrency exchanges are also required to implement screening processes to detect and prevent transactions with individuals or entities that are subject to sanctions. This includes the use of automated software that compares customer information against sanctions lists, and regular updates to these lists.

5- Maintaining The Trust of The Customer

Online cryptocurrency exchanges have the responsibility to protect the personal information of their customers and by collecting and verifying their identity through the KYC process, they can maintain the trust of their customers and provide them with a secure and compliant service.

Conclusion

In conclusion, online cryptocurrency exchanges ask for know-your-customer (KYC) information for the purpose of anti-money laundering (AML) to comply with legal regulations, mitigate risks, protect the integrity of the cryptocurrency ecosystem, avoid sanctions and maintain the trust of the customer. This helps to prevent financial crimes and ensure the security of the platform for its users.
