Final Article: I'm focusing on Blockchain: Blockchain

Through this I will find sources and articles like I did before and create edits. I will also monitor the talk page to see any feedback on my sources. I can add further depth into how it affects different aspects in the real world while expanding on the topic itself.

Draft of Contributions:

Blocks hold batches of valid transactions that are hashed and encoded into a Merkle tree. Each block includes the cryptographic hash of the prior block in the blockchain, linking the two. The linked blocks form a chain. This iterative process confirms the integrity of the previous block, all the way back to the original genesis block. Essentially, the blocks make up transactions with a level of identity into who's contributing to the transactions. Rather than storing an exact identity, blocks rely on your unique digital footprint or signature to store information. [1]


Blockchain was invented by a person (or group of people) using the name Satoshi Nakamoto in 2008 to serve as the public transaction ledger of the cryptocurrency bitcoin. The identity of Satoshi Nakamoto remains unknown to date. The invention of the blockchain for bitcoin made it the first digital currency to solve the double-spending problem without the need of a trusted authority or central server. Santoshi designed it to optimize about 1 Megabyte worth of transactions through Bitcoin. The central processes and setup of Blockchains remains quite stable and unchanged from its development regardless of the Bitcoin changing drastically.[2]


Nicholas Weaver, of the International Computer Science Institute at the University of California, Berkeley examines blockchain's online security, and the energy efficiency of proof-of-work public blockchains, and in both cases finds it grossly inadequate. In order to achieve useful information about the transactions happening in cryptocurrency, a blockchain analysis has to occur. By presenting data on a blockchain through visual representation, modeling, and clustering, the process of blockchain analysis is completed. Private companies usually account for this process through contracting with companies such as Bitcoin and Ethereum.[3]


The journal encourages authors to digitally sign a file hash of submitted papers, which are then timestamped into the bitcoin blockchain. Authors are also asked to include a personal bitcoin address in the first page of their papers for non-repudiation purposes. A hash essentially consists of a string of numbers and letters. Made up of a mathematical formula, a hash takes a variable of characters and turns it into a fixed number of characters in a string.[4]


Mining nodes validate transactions, add them to the block they are building, and then broadcast the completed block to other nodes. Nodes are essentially assigned to one per transaction. As a transaction is made, nodes are responsible for the validity of a transaction and logging them. An electronic vote or decision is often made post node validity to rule out fraudulent transactions and keep account of valid ones. Nodes also protect for changing of log entries as they work alongside hashes and if one entry is changed hash is changed, therefore nodes don't allow for the changes to occur.[5]

Peer Editing (Sid Gupta - Sid900) -[edit]

  1. A more technical analysis of blockchain would serve the purpose of broadening the scope of understanding for the article.
  2. Clear subheadings for each topic would make the material easier to understand.
