LONDON -- In October 2020, Miami-based art collector Pablo Rodriguez-Fraile spent almost $67,000 on a 10-second video artwork that he could have watched for free online. Last week, he sold it for $6.6 million. The video by digital artist Beeple, whose real name is Mike Winkelmann, was authenticated by blockchain, which serves as a digital signature to certify who owns it and that it is the original work. It’s a new type of digital asset - known as a non-fungible token (NFT) - that has exploded in popularity during the pandemic as enthusiasts and investors scramble to spend enormous sums of money on items that only exist online. Blockchain technology allows the items to be publicly authenticated as one-of-a-kind, unlike traditional online objects which can be endlessly reproduced. “You can go in the Louvre and take a picture of the Mona Lisa and you can have it there, but it doesn’t have any value because it doesn’t have the provenance or the history of the work,” said Rodriguez-Fraile, who said he first bought Beeple’s piece because of his knowledge of the U.S.-based artist’s work. “The reality here is that this is very, very valuable because of who is behind it.” Examples of NFTs range from digital artworks and sports cards to pieces of land in virtual environments or exclusive use of a cryptocurrency wallet name, akin to the scramble for domain names in the early days of the internet.“Non-fungible” refers to items that cannot be exchanged on a like-for-like basis, as each one is unique - in contrast to “fungible” assets like dollars, stocks or bars of gold. The computer-generated video sold by Rodriguez-Fraile shows what appears to be a giant Donald Trump collapsed on the ground, his body covered in slogans, in an otherwise idyllic setting. OpenSea, a marketplace for NFTs, said it has seen monthly sales volume grow to $86.3 million so far in February, as of Friday, from $8 million in January, citing blockchain data. Monthly sales were at $1.5 …

The largest province in Vietnam, about 16,490 square kilometers in size , Nghe An adjoins Thanh Hoa Province to the north and Ha Tinh Province to the south, bordering Laos to the west and the ocean to the east. An said he had not returned to Nghe An for nearly a decade, with his trip late last year reminding him of the province's many beautiful, pristine landscapes he has yet to discover. Lam River flows past Khe Bu Village near Pu Mat National Park in Con Cuong District. The village is inhabited by the Dan Lai ethnic minority who keep both their natural surroundings and lifestyle intact. A small corner of Khe Bu Village, where tourists can experience the rustic lifestyle of the Dan Lai. Nowadays, as the smallest ethnic minority in Nghe An, the Dan Lai reside solely in the mountains bordering Laos. Once upon a time, it is said, after a local committed a terrible crime, the king penalized the village, forcing its inhabitants to seek refuge in the dense forest where they slept upright to evade danger. Leaving the village, An crossed the Pha Lai suspension bridge. Late in the afternoon, he caught a group of locals crossing the bridge on their way home after a day working in the nearby rice fields. Located on the Ho Chi Minh trail near the border with Laos, the Thanh Chuong tea hills in Nghe An, 330 kilometers south of Hanoi, has an unusual setting. More than 50 years ago, a dam was built here to irrigate more than 700 hectares of rice fields in Thanh An and Thanh Thinh communes of Thanh Chuong District. Three years ago, local farmers began growing green tea. Now there are nearly 200 households growing tea across more than 400 hectares. Tea estates in Moc Chau, Thai Nguyen and Da Lat can be visited on foot, but those in the Thanh Chuong hills are only accessible by boat. Rice fields in Cam Son Commune of Anh Son District reflect a resplendent golden yellow. …
