FaunaDB 倒闭，计划开源
#开源
FaunaDB 是一种组合关系和文档功能的无服务器数据库，数据存储在 JSON 文档中，保留了一致性、联结和外键支持等关系功能。开发该数据库的创业公司 Fauna 因资金链中断而宣布于 5 月底倒闭，该公司计划开源 FaunaDB 的核心技术，希望开源社区能延续其遗产。Fauna 创业公司曾在 2020 年筹集到 2500 万美元的风投，上周宣布终止服务。除了发布数据库开源版本外，查询语言 FQL 也将公开。

“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. It’s a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. “This is how new coins are created” and new transactions are added to the blockchain, says Okoro.
