To defend against the volatility of the cryptos held as collateral, they are often over-collateralized. For example, the DAI stablecoin (valued at $1 and collateralized by Ethereum) has a collateralization ratio of 150%, which means every DAI created is backed by a minimum of $1.50 of ether. These stablecoins are backed by a reserve of physical belongings corresponding to gold, oil, or real estate. For occasion, Digix Gold is backed by a reserve of gold, with one DGX representing one gram of gold. Stablecoins are virtual currencies pegged to an asset similar to fiat money or gold.

This combination of properties results in a system that, by design, timestamps and records all transactions in a secure and everlasting manner, and is well auditable sooner or later. In addition to the above, because of its distributed nature, the system is very resilient to downtime. All these properties mixed makes an appealing system for all kinds of applications, and indeed explains much of the curiosity in the expertise.

Succeeding with such a hack would require that the hacker concurrently control and alter 51% or more of the copies of the blockchain so that their new copy becomes the bulk copy and, thus, the agreed-upon chain. Such an attack would also require an immense amount of cash and assets, as they would need to redo the entire blocks as a end result of they would now have totally different time stamps and hash codes. A database normally buildings its data into tables, whereas a blockchain, like its name implies, structures its information into chunks which would possibly be strung together. This data structure inherently makes an irreversible time line of data when carried out in a decentralized nature. When a block is filled, it is set in stone and becomes part of this time line.
