This credo, ably explained by Steve Forbes  here   ( among many places ) , is vital for a developing country economy to attract the investment it needs . Even in developed countries, as John Tamny explained  here  on Forbes . com, a stable currency value is the key to investment because those who invest are expecting a stream of future earnings to earn back their investment plus some profit . Instability in currency values mean that an investor cannot accurately predict the value of those future earnings . This uncertainty makes

How do Bitcoin works http://techglamour.com/what-is-bitcoin-and-how-does-bitcoin-work/ Bitcoin is a kind of self - contained virtual currency . We can assume that bitcoin is like a money in digital . We can use it to trade and purchase goods and service online . Unlike real money, bitcoin does not need intermediaries like bank . It proceeds through the system called BLOCKCHAIN . Transaction When there is no regulator bitcoin need fraud protection . Under Bitcoin policy, every transaction we made are public . For example, account A sent 0 . 8912 bitcoin to account B When this transaction occur everyone can realize it . Then, when we collect all the transactions that account A has been made and do the algebra we will get the balance of account A . Finally, we can compare the information we get with other to make sure that what we get it is correct . This way allows the receivers to check the sender ’ s transaction that has been occurred in the past and verify that

What is the purpose of a distributed ledger  ? Decentralization https://daily.financialexecutives.org/smart-contracts-pushing-blockchain-beyond-bitcoin/ This is a core concept and benefit of blockchain. There is no need for a trusted third party or intermediary to validate transactions; instead a consensus mechanism is used to agree on the validity of transactions.

H ow does distributed ledger work (compares to a bank) ? https://www.wikihow.com/Write-an-Accounting-Ledger Ledgers, the foundation of accounting, are as ancient as writing and money. http://www.olcinc.com/General-Ledger.php Their medium has been clay, wooden tally sticks (that were a fire hazard), stone, papyrus and paper. Once computers became normalized in the 1980s and '90s, paper records were digitized, often by manual data entry. These early digital ledgers mimicked the cataloguing and accounting of the paper-based world, and it could be said that digitization has been applied more to the logistics of paper documents rather than their creation. Paper-based institutions remain the backbone of our society: money, seals, written signatures, bills, certificates and the use of double-entry bookkeeping. Computing power and breakthroughs in cryptography, along with the discovery and use of some new and interesting algorithms, have allowed the creation of
