因为苏丹武装部队一直在阻止人道主义援助物资进入苏丹境内，在最近的这次武装冲突持续一年后，苏丹陷入了饥荒。
苏丹的人道主义危机已达到极其严重的程度。联合国秘书长安东尼奥·古特雷斯已就饥荒向安理会发出警报。联合国安全理事应立即采取行动，包括对阻碍人道主义援助送达的个人实施定向制裁。 source

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
