Kuhusu TRON
Tron is a decentralized, proof-of-stake blockchain with smart contract functionality. The cryptocurrency native to the blockchain is known as Tronix. It was founded in March 2014 by Justin Sun and since 2017 has been overseen and supervised by the TRON Foundation, a non-profit organization in Singapore, established in the same year. It is open-source software.
Tron was originally an Ethereum-based ERC-20 token, which switched its protocol to its own blockchain in 2018. On some cryptocurrency wallets, users can't withdraw their funds until they have enough amount for the network fee. WikipediaKuhusu Dola ya Marekani
Dolar ya Marekani ni pesa halali ya Marekani. Alama yake ni $.
Dolar ya Marekani inapatikana kwa noti za dola 1, 2, 5, 10, 20, 50 na 100. Kuna pia sarafu ya dola 1.
Dolar moja ina senti 100. Senti huitwa pia "penny" nchini Marekani. Kuna sarafu za nusu dolar, robo dolar na sarafu za senti 10, 5 na 1.
Hadi mwaka 1969 noti ya dolar ya Marekani ilikuwa na ahadi ya kwamba serikali ya Marekani itampatia kila mtu dhahabu kulingana na thamani ya dola hizi akipenda kuzibadilisha.
Usawa huu na thamani ya dhahabu ulifutwa. Leo hii dolar ya Marekani ni pesa ya kuiamini serikali kama pesa zote. Maana yake watumiaji husadiki ya kwamba serikali haitachapisha dola kushinda uwezo wa uchumi na thamani ya bidhaa zilizopo nchini Tanzania.
Tangu mwisho wa Vita Kuu ya Pili ya Dunia dolar ya Marekani imekuwa pesa kuu duniani na sehemu kubwa ya biashara ya kimataifa hukadiriwa kwa dolar hizo. Lakini tangu kupatikana kwa Euro mwaka 1999 umuhimu wa dolar ya Marekani imeanza kupungua polepole. Hata hivyo nchi mbalimbali zimeachana na sarafu zao na kuamua kutumia dolar ya Marekani tu, k.mf. El Salvador. Wikipedia
