Implementations of blockchain technology

Decentralized finance is an emerging financial technology based on secure distributed ledgers similar to those used by cryptocurrencies. The system removes the control banks and institutions have on money, financial products, and financial services.

Non-fungible tokens are cryptographic assets on a blockchain with unique identification codes and metadata that distinguish them from each other. Unlike cryptocurrencies, they cannot be traded or exchanged at equivalency. This differs from fungible tokens like cryptocurrencies, which are identical to each other and, therefore, can serve as a medium for commercial transactions.

Using blockchain for identity management can allow individuals to have ownership of their identity by creating a global ID to serve multiple purposes. Blockchain offers a potential solution to the above challenges by allowing users a sense of security that no third party can share their PII without their consent.

Emerging: newly formed or prominent

Ledger: a digital record that is used similarly to an accounting ledger (as for maintaining a list of transactions)

Fungible: being something (such as money or a commodity) of such a nature that one part or quantity may be replaced by another equal part or quantity in paying a debt or settling an account

Commodity: an economic good

Asset: the entire property of a person, association, corporation, or estate applicable or subject to the payment of debts

Metadata: data that provides information about other data

PII: personally identifiable information

枉為人師

某天,我坐在客戶服務檯工作。

有一位客人問什麼卡有折扣。

我道︰「會員銀卡或以上有折扣。」

客人說︰「我是教師,教聯證買書有沒有折扣?」

我道︰「教聯、教協證件沒有折扣,Teacher Net 證或學校訂書才有折扣。」

(按︰教協已經於2021年解散。)

客人厲聲說︰「Teacher Net 由什麼機構發出,何等權威,怎樣申請?」

我道︰「不太清楚申請方式,我剛剛在電腦上也找不到。」

客人道︰「你們接受Teacher Net,為什麼當中由來也說不出來?」

我說︰「那麼你可以問CS。」

客人說︰「什麼是CS?」

我說︰「Customer service.」

客人道︰「即是要問你公司的客服。」

客人表示不滿轉身便走。

復泳

今日在室內池游

幾個月沒有做運動

游了三十五分鐘後小腿抽筋

拉筋都不能舒緩

安全至上,提早上水

救生員說今天水溫偏低,有直接影響

太久沒有下水都有關係

今天當熱下身

歌曲

之前去台北旅遊

找不到九份的咖啡店

印象中只吃了碗牛肉麵
