沙特阿拉伯海关已试点基于区块链平台TradeLens的货物运输！

5月22日消息，沙特阿拉伯海关部门已通过TradeLens首次试点沙特阿拉伯港口至比利时的货物发送。据悉，TradeLens是马士基与IBM合作开发的基于区块链的平台。2018年底，沙特海关与TradeLens实现关联，该部门将其电子数据交换（EDI）系统FASAH与TradeLens集成。

In recent years, blockchain-based use cases have found significant traction within the freight industry. Blockchain’s ability to decentralize information and store it in an immutable ledger accessible by every stakeholder in the value chain can drive industry-wide collaboration and increase supply chain efficiency. 

The customs department of Saudi Arabia is the latest entrant to the blockchain space, as it successfully piloted its first shipment through TradeLens, a blockchain-based platform developed collaboratively by Maersk and IBM. The shipment departed from the Saudi Arabian port of Damman, setting sail onboard the Maersk Sebarok, and reached the port of Rotterdam, from where it was put on a truck en route to its final destination in Belgium.

俄罗斯NSD将追踪数项加密资产所有权!

俄罗斯国家结算存款机构莫斯科交易所国家结算存管处（NSD）将于6月份推出D3（分布式数字存储库），追踪数项加密资产的所有权，并选择瑞士作为合并D3的管辖区。该项目自2017年以来一直在建设中，NSD创新主管兼董事Artem Duvanov表示，之所以选择瑞士，是因为其友好的监管环境和在数字资产方面做市的潜力。此外，其还透露，下一步将向D3添加一个信誉良好的稳定币，以实现场外交易（OTC）加密交易，无交易对手风险和交割与支付证券交易，这意味着交易双方同时完成。

Russia’s National Settlement Depository (NSD) plans to launch its long-awaited digital asset ledger next month – 5,000 kilometers away from the institution’s Moscow headquarters.

Revealed exclusively to CoinDesk, the Moscow Exchange Group subsidiary chose Switzerland as the jurisdiction to incorporate D3ledger (Decentralized Digital Depository), a project that’s been in the works since 2017. 

Artem Duvanov, head of innovation and a director at NSD, said it picked Switzerland for its congenial regulatory environment and potential for market-making in digital assets. 

He said:  

“In terms of laws, [Switzerland] allows the tokenization of at least some kind of securities. That’s the first thing. And it’s favorable for such things because there is market demand.”

4、大咖链语

加勒比国家的法律制度比澳大利亚更加灵活?

澳本聪（Craig Wright）发文提到加勒比国家的法律制度比澳大利亚更加灵活。澳本聪表示：“2011年，我在加勒比地区的银行账户上有大约3000万美元。它们在在系统性的信托及公司之中。如果我把这些钱带回澳大利亚作为现金使用，我最终将直接为其缴税。”

Craig Wright seems to have raised BSV from the dead today. The Australian lawyer known for referring to himself as Satoshi Nakamoto filed an application with the United States Copyright Office claiming authorship of the Bitcoin Whitepaper.

The news caused many to speculate about its legal implications, however, the truth is that BSV had an abnormal rise, exceeding 83% profit in the last 24 hours.

But besides the strange application, one detail is quite interesting. The Application shows that Craig Wright claims to be a citizen from Antigua and Barbuda and not from Australia.
