What is double-spending with example?
The issue of double-spending is a problem that cash does not have; if you pay for a sandwich with a $10 bill, turning that bill over to the maker of the sandwich, you cannot turn around and spend that same $10 elsewhere. A transaction using a digital currency like bitcoin, however, occurs entirely digitally.
What does double-spending mean?
Double-spending is a potential flaw in a digital cash scheme in which the same single digital token can be spent more than once. Unlike physical cash, a digital token consists of a digital file that can be duplicated or falsified.
What is double-spending how it is solved?
Reverse an already-sent transaction

What is blockchain system?
Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. ... Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant's ledger.
How does ethereum prevent double-spending?
In summary, the blockchain prevents double-spending by timestamping groups of transactions and then broadcasting them to all of the nodes in the bitcoin network. As transactions are time-stamped on the blockchain and mathematically related to the previous ones, they are irreversible and impossible to tamper with.

In place of a trusted third party, Nakamoto used a chain of cryptographically-signed transactions secured by proof-of-work to order and validate payments.
Can Bitcoin be duplicated?
You can replicate bitcoin. You can replicate all the transactions and then some. The longest chain theory believes that longer the chain of blocks, the more trustworthy it is. By replicating the bitcoin blockchain, people don't begin transacting on your blockchain.
