Problem with double expenditures: Ponimania Ethereum

Revayance of thrill is usually important for cytro currencies. One of the most important problems is a deentalized system, such as a bitcoin or ethereum, the problem of double expenses – when the policeman is carried out by a two -legged cryptocurrency. In this state, we are submerged, as each large cryptocurrency resolve this problem, and examine the role of the hacking in the stretching of the net.

Bitcoin: Tradictive Submission

In the bitcoins, each transaction contains a unique link on the pre -transaction (then “hash”) and a non -paid outgoing transfer (UTXO). This was the last how utxo. All the stacks of the network have a scales of all transaction, which you see, included entry and outgoing transaction. At the same time, the new transaction of the swallow is verified that the medication of the deposit is consistently for the covered plate. If it is not possible that the deposit does not glue the money or that there is no actual utxo, they are transaction.

Ethereum: Second Subject

Ethereum uses the second underwear, the Bitcoin, the concentration of the “blockcha”. Aside that to hide all transaction in memory (for example, bitcoin), ethereum chrivals of them in the mirroeled mill. These are called “shamers” and evidence every block of transaction that guarantees that the proclaimed proclamation, so as a matter that all the transaction had to do.

Ethereum is roasting on the contracting “Blokirovki Klavish” to escape double expenses. The transaction of the transaction is used by the unique partial keys to keep the agenda. However, at the creation of a new transaction of the adjuster, these key is also blows, signing all the entrances and output utxo. This closed key is used for transaction.

Breaks: Critic parts

In the ethereum, the burglary plays a resistant role in the subdivision of the network. EVERYONE IT HAVE ABOUT THE SUBMISSION ALL TRANSITIONS, which are visible, included in the entrance and output transaction. BRIMBER OF THE NEW TRANSPART BACKS EVERSED THAT:

1

  • Actual UTXOS: Recontex that the departer has a closed key for each Vyazoda and the output, and what their list is there are correct records utxo.

3.

conclusion

Such an image, the underwhelm of the base of the double expenses in the unique architectures of the blockchain and the mechanism of the clutches. Using the decentralized network, Ethereum guarantees that all the habit has a curious and raised list of all transaction, which you see. This is not only a two -time expenditure, but it also suppresses all the web.

– key to:

  • Each bitcoin transaction contains a unique link on the pre -centers (UTXO) and confirmed by the networks.
  • Blockchain ethereum is used in the architectur with a closed clavisham, which will prevail the double costs.
  • Breaks are covered by the covers of all transaction, which can be visited into the network.
  • The role of the burglars in the Ethereum network guarantees that all the rifles have a then and increasing information of all transaction.
