Ok, I guess I am referring to a buyer of BitCoin that a find out the transaction failed to get an update in the blockchain. This must happen since there is cause for concern over the double-spend problem.<br />
<br />
So, I mean the transactions which seemed to be successful on the client application, that got reversed by a failed update to the blockchain.

I am learning a few details the &quot;double-spending problem&quot; and it seems that Bitcoin is not really that protected from them.<br />

<br />
My question is whether there are an stats which track the number of Bitcoin transactions that have been reversed by the Bitcoin not actually being on the account of the spender? Or is this a failure that can not be tracked, due to Bitcoin's lack of centralization?<br />
<br />
If you have this statistic, it would be great to see any competing currencies to see if they have a different failure rate...

Bitcoin: any data on the number of transactions REVERSED?

Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.

Databases are organized collections of data, most commonly accessed through management systems including schemas, tables, queries and processes that allow users to enter and manipulate the information or utilize it in other fashions, such as with web applications or for reporting purposes.

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
