You may have confused the ICC with the ICA. The ICC (International Criminal Court) is a separate entity from the ICA (International Court of Arbitration) and primarily deals with cases related to war crimes, crimes against humanity, and genocide. Its jurisdiction is limited to individual criminal responsibility and does not extend to resolving territorial disputes or intervening in ongoing conflicts between nations.

Regarding the South China Sea territorial disputes, the International Court of Arbitration (ICA) ruled in favor of the Philippines, stating that China's claims to historic rights within the "nine-dash line" were inconsistent with international law. However, the ICA does not have the power to enforce its rulings, and China has rejected the court's decision, continuing its activities in the disputed sea.

Concerning the situation between Russia and Ukraine, it falls under the realm of international relations and geopolitics. The ICC's jurisdiction does not extend to resolving conflicts between states or awarding territories.

The birth of digital currency has indeed brought many changes to human life, and they have become a popular payment method.  However, the security of digital currencies has also been an important topic.  Decentralized technology can indeed solve some digital currency security issues.  For example, blockchain technology is a decentralized technology that can make digital currency transactions more secure and transparent.  Through blockchain technology, the transaction records of digital currency cannot be tampered with and cannot be forged, which can effectively prevent fraud and counterfeiting.  However, there are also some problems with decentralized technology.  For example, decentralized technology can lead to transaction inefficiencies and increased transaction costs.  In addition, decentralized technology may also bring some new security issues, such as hacker attacks and network failures.  Therefore, to make digital currency more secure and convenient, a comprehensive application of multiple technologies is required.  In addition to decentralized technology, it is also necessary to strengthen the security protection measures of digital currency, such as strengthening the application of cryptographic algorithms, improving transaction security, strengthening supervision and management, etc.  Only through the comprehensive application of multiple technologies can the security and reliability of digital currency be better protected, so as to better serve people's production and life.
