pol

PoL (Proof of Liquidity) is a consensus mechanism designed to validate transactions through the provision of liquidity. Unlike traditional Proof of Work (PoW) or Proof of Stake (PoS), PoL rewards participants with block rewards for providing liquidity. This mechanism is commonly used in decentralized exchanges (DEX) or liquidity pools to incentivize users to provide liquidity, thereby enhancing market efficiency and stability. The advantage of PoL lies in its ability to encourage more liquidity providers to participate, strengthening market depth and trading liquidity.

first_img A former Polish police officer has been charged in the Zondacrypto case, and the police are searching the location where its founder went missing

The Polish prosecutor's office has charged a former police officer in the case of the collapsed cryptocurrency exchange Zondacrypto. The Central Bureau of Cybercrime (CBZC) in Poland detained Artur K. on Tuesday under the orders of the organized crime department of the national prosecutor's office. He faces two charges: one for participating in an organized crime group, and the other for causing significant property losses to BitBay, BB Trade Estonia, and another entity, assisting in the misappropriation of entrusted property, aiding computer fraud, and money laundering. The prosecutor's office stated that a search of his residence uncovered documents related to the operation of the exchange, and he is being questioned as a suspect; the prosecutor's office will decide whether to apply for pre-trial detention.Meanwhile, the police in Katowice are searching and investigating a fuel depot, which is the last known location of Zondacrypto founder Sylwester Suszek before he went missing in March 2022. The case is classified as illegal deprivation of liberty rather than a disappearance, as a suspect has been accused of removing a hard drive from the gas station's surveillance camera.Suszek founded the exchange in Katowice in 2014, originally named BitBay, and relocated its registration to Estonia as BB Trade Estonia in 2020, rebranding it as Zondacrypto, claiming to have 1.3 million customers, most of whom are Polish. The exchange froze withdrawals and went offline in April, and the Estonian Financial Intelligence Unit revoked its operating license on June 29. Since August, at least five people have been charged, including former Polish Olympic Committee president Radosław P. All public respondents have denied the charges, and the related accusations have not yet been tried in court.

Analysts: Coinbase, Robinhood, and Circle may be early beneficiaries of the SEC's tokenized stock policy

According to CoinDesk, the U.S. SEC has launched a five-year innovation exemption that provides a pathway for eligible tokenized U.S. stocks to be traded through automated market makers (AMM) on public blockchains. Analysts from Goldman Sachs and Citizens believe that Coinbase, Robinhood, and Circle could become early beneficiaries of this policy.The new framework requires tokens to retain shareholder rights such as dividends and voting rights while imposing limits on the number of stocks and trading volume that trading platforms can offer. Goldman Sachs stated that Coinbase's existing tokenized stock products already possess several of the required features, and its institutional custody business and Coinbase Tokenize may also benefit.However, Coinbase's current trading platform uses a centralized limit order book, and to operate a trading venue directly under the exemption, it will still need to build AMM infrastructure or route trades to decentralized trading platforms on Base.Currently, the stock tokens offered by Robinhood for markets outside the U.S. are derivatives that only provide price exposure and do not possess the complete shareholder rights required by the framework, thus requiring further adjustments to the product. Robinhood has previously stated plans to add 1:1 redemption and voting rights features for stocks.Analysts also believe that an increase in on-chain securities trading may drive demand for tokenized cash, benefiting Circle indirectly, with USDC potentially being used for settlement and collateral in on-chain markets.
