Verifying block database integrity bitcoin miner


Looking for a radical way to bolster all three points of the classic security CIA triad? Lucky for you, there's Bitcoin. Specifically, there are two concepts lurking in the Bitcoin phenomenon that are considerably more important than the currency itself: The direction this scripting capability will take isn't clear yet.

A startup called Ethereum is well underway with its own programming language, Ethereum Script, and a platform for developers to create decentralized applications based on smart contracts without the middleman. Another startup called Counterparty offers peer-to-peer financial tools specifically tied to Bitcoin. When it comes to the Bitcoin block chain, it's already crystal clear that there are big potential wins for security.

If you're aware of Bitcoin, you're familiar with the idea that so-called Bitcoin miners harness high-speed computational processing power in an effort to solve mathematically difficult problems to secure and verify transactions, and create Verifying block database integrity bitcoin miner. Miners earn transaction fees and subsidies -- paid in Bitcoins, of course.

A new block is written every ten minutes, extending the chronological block chain, which is shared among nodes on a peer-to-peer network using the Bitcoin protocol. But it's more complicated and far more elegant than that. The block chain is a series of data records -- time-stamped transactions -- stored in a database.

The hash of each block beginning with the "Genesis block" is used to link to the next so that there is a single forward pathway through the blocks: This is the "chain. When a Bitcoin transaction occurs, the previous transaction's hash and the public key of the next owner are verifying block database integrity bitcoin miner signed with the current owner's private encryption key. If you want to transfer your Bitcoin that is, buy somethingyou have to have your secret key.

No key, no possession. Once an entry is written into the block chain, it cannot be altered without regenerating the previous blocks. In other words, data can be added to the transactions database, but it cannot be removed. This prevents double-spending and ensures the forward linking of the block chain. Therein lies the security angle. If a company were to store its general ledger in the Bitcoin block chain, a bad apple in the accounting department would be completely unable to go back without detection and alter previous entries to cook the books.

Think of the potential impact on fraud prevention. While it might seem odd to think of verifying block database integrity bitcoin miner those kinds of transactions in Bitcoin's block chain, in fact, you can store pretty much any sort of data. And people have occasionally done so, though admittedly with a bit of a "toying with the system" approach. There's a picture of Nelson Mandela in the block chain, for instance.

Verifying block database integrity bitcoin miner even a model hacker exploit tip of the hat to Ken Shirriff's blog:. Note that the exploit had to do with a client program called MyWallet, not with the Bitcoin technology -- one definite issue in the Bitcoin economy is that wallet programs that store private keys have to remain unhacked. Now, writing to the Bitcoin block chain isn't free.

It is actually a little pricey if you start thinking about storing megabytes, so no one's likely to use it for directly storing their logs. But the concept of a decentralized database whose records are "secured" by 10, computers can, of course, be extended to other block chains.

A startup called Factom is working this angle. As Peter Kirby, the president of the Austin-based company, put it: Factom is just gearing up, but eventually will let its customers write to a separate block chain that's more suitable for data entries. Cleverly, however, it ties those entries back to the Bitcoin block chain by storing a hash of each new Factom in the next Bitcoin verifying block database integrity bitcoin miner added to the chain.

The hash can verifying block database integrity bitcoin miner used to verify the time of the Factom transactions and that the Factom block hasn't been tampered with. There are other startups doing this, too. Storj is beta testing a distributed cloud storage service that uses block chain technology. MetaDisk is a file sync app built atop the Storj block chain infrastructure.

BlockCypher is building a cloud block chain platform with APIs that make it easier for developers to build applications based on this technology.

There's more than just secure recordkeeping lurking here, however. Digital assets can be controlled just like Bitcoins which are, verifying block database integrity bitcoin miner all, digital assets themselvesso digital rights management may well wind up with a whole new look and new capabilities such as easily transferring ownership of your music collection -- just try reselling stuff you bought through iTunes.

I can't help but think that there will be direct applications of block chain technology to the security space beyond immutable records. I don't have the killer block chain security app figured out yet, but I'm sure, all the same, that non-fungible developments spinning out of Bitcoin will be fascinating to watch from a security perspective.
