Double-spending

Blockchain technology holds great potential for a wide variety of industries. To understand what opportunities the technology may hold for the arts field, and its potential for individual organizations, it is essential to understand the basic technology and the risks and opportunities it presents. In this three part series, we will detail how blockchain works part 1 , its applications for the arts part 2 , and the risks arts managers should consider before deploying a blockchain based system part 3.

Satoshi Nakamoto, the alias of an anonymous programmer, created blockchain for use in cryptocurrencies, such as Bitcoin. Any attempts to double spend coins or fraudulently alter balances will be rejected as other computers check the ledger history to verify the transaction. Every blockchain begins with a genesis block. This block contains the original set of transactions or data. Once one computer believes it has hashed the data in a manner which meets the requirements, it sends its solution to every other computer on the chain to verify the solution.

The user who successfully adds a block to the blockchain will typically receive a reward such as cryptocurrency. Figure 2: Linking blocks together and the underlying Merkle tree CC3. These alternate methods of block adding do not require the competitive solving of a cryptographic puzzle in order to add a block to the chain, but otherwise employ the same basic blockchain tenants such as diversified ledger storage, cryptographic hashing, and Merkle trees.

The most well-known blockchain, the Bitcoin blockchain, is a permissionless blockchain. This means that anyone can view the entire ledger and enter new transaction data. Most cryptocurrencies operate on permissionless blockchains.

Alternately, permissioned blockchains limit the ability to read or input data to specific parties. Permissioned blockchains are typically found in private business and government settings. The blockchain creation process means that data stored on the blockchain is nearly impossible to change. If a user alters data that is stored on the blockchain in any manner, when saved, that data will result in a new hash value.

This new hash value will subsequently change the hash values all the way up the Merkle Tree, resulting in a new hash value for the entire block. Further, because the ledger is distributed in full across many users, should the ledger be damaged or destroyed in any one location, hundreds or thousands of backup copies are readily available. The permanence of data stored on the blockchain is the heart of its appeal, yet it is also the programs Achilles heel. Incorrectly input data cannot be changed, and fraudulent transactions cannot easily be fixed.

Method of altering a blockchain are controversial, and sometime criminal, as they undermine data integrity. Running a proof of work blockchain requires an enormous amount of energy. Currently, the Bitcoin blockchain alone is estimated to consume almost as much energy as Ireland. As a result, one of the most widespread malware programs out today acts as a parasite on unsuspecting computers to use their energy to mine bitcoins.

The Bitcoin blockchain is a permissionless blockchain which relies on the proof of work block validation method. Other validation methods, such as proof of stake and round robin require significantly less energy because they do not rely on multiple computers attempting to simultaneously solve a cryptographic puzzle. Further, for companies deploying a private blockchain the hardware requirements are significantly greater than those of a centralized system.

In order to achieve the high level of redundancy needed to provide benefits beyond a centralized system a blockchain needs to be stored on hundreds, if not thousands of networked computers. Ideally these computers would be stored in various locations to prevent total loss due to fire or other catastrophic possibilities. The increased technology costs may be significantly greater that the security benefits. All Research Tracks. Artificial Intelligence. CRM Systems.

Cardano (ADA)

This is a subpage; for more information, see the Requests for comments page. The Wikimedia Foundation currently accepts cryptocurrency donations in currencies including Bitcoin , Bitcoin Cash , and Ethereum , as explained on the "Other ways to give" page. I propose that we stop accepting cryptocurrency donations. I don't expect that this change will cost us much in terms of lost donations, though I am still waiting for data on this. Even if we assume that those donating using cryptocurrencies would choose not to donate at all if crypto wasn't an option rather than donating in some other currency , my suspicion is we take few donations this way.

Edelstein, who announced on Monday that he would challenge Netanyahu for the party leadership, glosses over the figures in the poll indicating Likud voters would overwhelmingly support Netanyahu over him in Likud primaries. The survey also suggested Likud would win 20 seats under his leadership and 34 under Netanyahu, though the former Knesset speaker would be better positioned to cobble together a coalition.

Since that time, this paper has taken on a life of its own In the earlys, when the commercial Internet was still young! Many thoiught that increased security provided comfort to paranoid people while most computer professionals realized that security provided some very basic protections that we all needed? Cryptography for the masses barely existed at that time and was certainly not a topic of common discourse. Security and privacy impacts many applications, ranging from secure commerce and payments to private communications and protecting health care information. One essential aspect for secure communications is that of cryptography.
