What is Blockchain and Wallet
What is Blockchain:
According to Wikipedia The blockchain is a public ledger that records bitcoin transactions. A novel solution accomplishes this without any trusted central authority: maintenance of the blockchain is performed by a network of communicating nodes running bitcoin software.Transactions of the form payer X sends Y bitcoins to payee Z are broadcast to this network using readily available software applications. Network nodes can validate transactions, add them to their copy of the ledger, and then broadcast these ledger additions to other nodes. The blockchain is a distributed database – to achieve independent verification of the chain of ownership of any and every bitcoin (amount), each network node stores its own copy of the blockchain. Approximately six times per hour, a new group of accepted transactions, a block, is created, added to the blockchain, and quickly published to all nodes. This allows bitcoin software to determine when a particular bitcoin amount has been spent, which is necessary in order to prevent double-spending in an environment without central oversight. Whereas a conventional ledger records the transfers of actual bills or promissory notes that exist apart from it, the blockchain is the only place that bitcoins can be said to exist in the form of unspent outputs of transactions.
Buying and Selling of Bitcoin
Bitcoins can be bought and sold both on- and offline. Participants in online exchanges offer bitcoin buy and sell bids.
Using an online exchange to obtain bitcoins entails some risk, and,
according to a study published in April 2013, 45% of exchanges fail and
take client bitcoins with them. However exchanges have since implemented measures to provide proof of reserves in an effort to convey transparency to users. Offline, bitcoins may be purchased directly from an individua or at a bitcoin ATM. Bitcoin machines are not however traditional ATMs. Bitcoin kiosks are
machines connected to the Internet, allowing the insertion of cash in
exchange for bitcoins. Bitcoin kiosks do not connect to a bank and may
also charge transaction fees as high as 7% and exchange rates $50 over
rates from elsewhere.
As of 2016 it was estimated there were over 800 bitcoin ATMs operating globally, the majority (500+) being in the United State.
Acceptance by Merchants:
In 2015, the number of merchants accepting bitcoin exceeded 100,000. Instead of 2–3% typically imposed by credit card processors, merchants accepting bitcoins often pay fees in the range from 0% to less than 2%
Merchants accepting bitcoin, such as Dish Network, use the services of bitcoin payment service providers such as BitPay or Coinbase. When a customer pays in bitcoin, the payment service provider accepts the bitcoin on behalf of the merchant, directly converts it, and sends the obtained amount to merchant's bank account, charging a fee of less than 1 percent for the service.
Acceptance by Non-profit Organisations:
Bitcoin is accepted by The Electronic Frontier Foundation, Greenpeace, The Mozilla Foundation, The Wikimedia Foundation, and The Free Software Foundation. Some U.S. political candidates, including New York City Democratic Congressional candidate Jeff Kurzon have said they would accept campaign donations in bitcoin. In late 2013 the University of Nicosia became the first university in the world to accept bitcoins and also began offering a degree program on the study of digital currencies
What is a Wallet:
A wallet stores the information necessary to transact bitcoins. While wallets are often described as a place to hold or store bitcoins, due to the nature of the system, bitcoins are inseparable from the blockchain transaction ledger. A better way to describe a wallet is something that "stores the digital credentials for your bitcoin holdings and allows you to access (and spend) them. Bitcoin uses public-key cryptography, in which two cryptographic keys, one public and one private, are generated. At its most basic, a wallet is a collection of these keys.
There are several types of wallets. Software wallets connect to the network and allow spending bitcoins in addition to holding the credentials that prove ownership. Software wallets can be split further in two categories: full clients and lightweight clients.
General Use:
According to a research produced by Cambridge University in 2017, there are between 2.9 million and 5.8 million unique users actively using a cryptocurrency wallet, most of them using bitcoin. The number of active users has grown significantly since 2013 (there were 0.3 to 1.3 million unique users at the time).

A great piece that sheds much needed light on some of the great theoretical/ideological debates in the contemporary crypto space. At CleanApp Foundation, we appreciate the emphasis on pragmatism, and emphasis on Blockchain/DTL/Crypto projects that offer real social utility. Looking forward to engaging more with your crew!
