What is Bitcoin?
A crypto gun is a form of electronic cash. It is a decentralized digital currency without a central bank or a single administrator. Bitcoin can send the user to peer-to-peer bite without intermediary requirements directly from the user. Transactions have been verified by the network node via cryptography and have been recorded in a public way. The distributor is called a blockchain. Bitcoin was discovered by an unknown person or group named Soto Nakamoto and released in 2009 as Open Source Software. Bitakayana received a prize in a process known as mine. They can be exchanged for other currencies, products, and services. Produced by research. The University of Cambridge estimates that in the year 2007, using cryptologic wallets, 29 to 5.8 million unique users were used, most of them used Bitcoin.
The domain name “bitcoin.org” was registered on August 18, 2008. In November 2008, Satkhi Nakamoto’s Bitcoin Title: A Peer-to-Peer Electronic Cash System. Link to a paper written in the title. The cryptography mailing list was released in January 2009 by applying bitcoin software as open-source code. Nakamoto’s identity remained unknown. In January 2009, the Bitcoin network was created when the first block of the Nakamoto Chain is dug, which is known as the Knowledge Block. The following text was embedded in this block’s currency market: This note is interpreted as a commentation on the timestamp and unrest caused by Functional-Reserve Banking. The first Bitcoin transaction receiver was Cyberfac Hall Finni, who first created Reusable Proof Off-Work System (RPOW) in 2004. Fini Bitcoin Software downloaded the software from its release date and got 10 bitcoins from Nakamoto. Other early cyberspace supporters are the creators of Bitcoin predecessors: creator of B-Wai Wei Dai, and Nick Szabo, creator of Bit Gold. Before being invisible in 2010, Nakamoto was calling for excavation of 1 million Bitcoins, when he gave network alert and handed over the code repository control to Governor Andreassen. Andresen later became the lead developer. Bitcoin Foundation Andresen then tried to decentralize the control. This left scope for debate is to develop on Bitcoin’s future development path.
Bitcoin is a pseudonym, which means that the address of Bitcoin is not connected to the real world organization. Bitcoin addresses are not identified individually, but all transactions in the blockkain are public. In addition, the transaction can be linked to the person and company with the use of “use of the system” (eg, transactions that cost money from multiple inputs, that inputs can be a general owner), and owners of specific addresses by securing public transaction information with known information. . In addition, the Bitcoin Exchange, where bittacquired traders are traded, may be required by law to collect personal information. In order to reduce financial secrecy, a new Bitcoin address for each exchange can be generated. For example, continuous decaying wallets generate pseudorandom “rolling addresses” for each transaction of a single seed, when only a single passphrase needs to be remembered for the recovery of the corresponding private keys. Researchers at this time Stanford University and Concordia University also showed that Bitcoin Exchanges and other entities use their proof of resources, liability, and zero knowledge to voluntarily disclose their address. “Bulletproofs”, a version of the secret transaction proposed by Greg Maxwell, was examined by Professor Dan Bonhah of Stanford. Other solutions such as Merkelized Abstract Syntax Trees (MAST), Mekl-Branch-Verfi and pay-to-script-hash (PSSH) with “Telefon Call Execution Syntax” have also been proposed to support personalized smart agreements.
What is UPI What does UPI mean? How does UPI work? How to send money with UPI:-
The UIPI or Unified Payment Interface is an immediate real-time payment system that helps transfer funds between two bank accounts through a mobile platform. So, the UIPI is a concept that can access multiple bank accounts in single mobile applications. This concept was introduced by the National Payments Corporation of India and it is regulated by the Reserve Bank of India and the IBA (Indian Bank Association).
What are the main features of the UPI?
Funds are transmitted instantly through instant payment service (IMPS), which are faster than NEFT.
As it is fully digital, the UPI can use 24 hours and all public holidays.
Single mobile application for accessing various bank accounts.
Using a virtual payment address, which is a unique ID provided by the bank.
Using the account number with the IFS code and mobile number with MMID or Mobile Money Identifier.
The MPIN or mobile banking personal identification number is required to ensure each payment.
Change USSD service by dialing * 99 # and select services like fund transfer, send money, send money, change non-financial services, change balance, change MPIN, etc. (Service charge of 0.50 is applicable).
Each bank offers its own utility for Android, Windows and iOS platforms. Bank can not charge or charge for the UPI service.
Benefits of sharing bills
Merchant payment, Utility bill payment, In-app payment, Otis payment, Best for Barcode-based payment.
You can file a complaint directly from a mobile app.

What does a safe platform do the UPI?
This API interface is a simultaneous single click payment based on two-factor authentication. This feature of the UPI has been linked to the regulatory guidelines so that it is the safest. 2 Factor authentication is the same as OTP. Here, the MPIN will be used instead of Open.
To cash transactions, the NPCI advisor has confirmed that the security will happen in the highly encrypted format of the transaction as a fool proof with the UPI. NPCI’s IMPS network has already invested more than Tk 8 crore. Transactions daily, which will increase the use of more mobile phones.
In order to access the UPI service, users will have to create a virtual payment address or VPA of their choice. They must link the VPA to their bank account. This becomes the financial address of VPA users and they do not have to remember the details like beneficial account numbers, IFCC codes or net banking user IDs and passwords to send or receive money. For a customer to pull and push this virtual address helps create extra security, the customer does not need to punch again in this description and there is no credential sharing.
