Blockchain technology is a decentralized network structure used to obtain consensus on changes to a ledger shared and distributed throughout a system. Blockchain technology allows for peer-to-peer trust-less validation and record-keeping that is superior to centralized database systems in many situations, in terms of security, reliability, and efficiency. Blockchains tend to be integrated with smart contract technology that serves as the mechanical-legal framework for interactions between the co... Continue reading...

Blockchains are intended to maintain integrity in the system without anyone needing to monitor or control it. By instituting a system of checks and balances that functions on its own accord through rules programmed into the protocol, and which also makes decisions and keeps records based on consensus throughout a peer-to-peer network, a blockchain oversees its own activities without requiring any trust in a central authority or the other parties involved. Continue reading...

Blockchain technology is already being used and developed for many important and impressive applications, and much more is yet to be discovered. Blockchains use distributed work to obtain consensus for changes to a distributed ledger.  Because of their nature, blockchains are incredibly powerful tools that can be used in many realms and applications. They offer security in that they are almost unhackable; any attempted unauthorized changes to the system are immediately obvious to the entire system because it is built on agreement and consensus among its many nodes. Because this structure gives each addition to the ledger, and the record in the ledger, a high degree of integrity and security, future applications of blockchains are being researched in various fields around the world.

A distributed ledger is a records system in which the same information is held redundantly across many nodes in a network, and is essential to blockchain technology. Centralized databases used to be the primary way that important records of transaction histories and so forth were held.  Databases validate the identity of those requesting access to the records by asking for and retaining personally identifying information. If that office building were to lose power, was hacked, or was destroyed, it is possible for all of the information to be lost or given over to hands of bad actors. Even with cloud storage backups, the security and financial risk to any one of these storage depositories remain a problem. Continue reading...

Blockchain technology does not always have to be implemented in a public peer-to-peer system. Blockchains rely on a network of computers, representing nodes, that collaborate and distribute the information required for the blockchain to function. The nodes in some blockchains can be established by any computer willing to run the client software for the network. Bitcoin and most cryptocurrencies are intended to function this way: as a public, open-source, permission-less, and trust less network. The nodes are used indiscriminately by the rest of the network as long as the node is performing the functions required of nodes, and this is called a proof-of-work system.  When Satoshi Nakamoto coded the first blockchain, his intention was to keep the network functioning with only one tier: “one CPU, one vote.”  That vision has encountered obstacles in the form of ASIC mining and other unforeseen circumstances that have empowered some nodes and groups of users over others. Continue reading...

Blockchains use distributed ledgers, which are decentralized and do not rely on centralized databases. Databases are the traditional way to store information and to keep it secure. When companies store information about their customers, or about the business itself, it is usually kept in a database connected to servers that handle requests for the information. The design for such a system tends to look like a wagon wheel:  a central hub with numerous spokes connecting it to the outer wheel.  Layers of security are heaped onto centralized servers and permit access to various levels of information is given to specific users.

The overarching theme of blockchains is that they can provide security and asset verification in a decentralized system, which is perhaps the best-known method for preventing fraud. Blockchains are a technological revolution that provides an opportunity to establish strong systems for digital identity. Here are some of the applications and uses for it: A user can authenticate a unique physical item by pairing them with a corresponding digital token. In that sense, these tokens serve to connect the physical and digital worlds. With a token assigned to each physical good, that can revolutionize supply chain management, managing intellectual property to prevent counterfeiting and fraud detection. Continue reading...

Blockchain, if applied on a broad basis, could lower costs substantially for both financial institutions and consumers, while also preventing fraud. This could upend the financial markets as we know it, in a good way. With blockchain, virtually any type of asset can be stored digitally and securely, meaning that money, equities, bonds, contracts, deeds, etc.. can be moved from peer to peer with little to zero fear of fraud, and no vulnerable (or costly) intermediary like a bank or a government. Continue reading...

Blockchain is an emerging technology and arguably one of the next “big things.” As with anything so big and impactful, it comes with a few issues and limitations. Before even diving into the technology behind blockchain and potential issues, perhaps one of the broadest issues facing blockchain is gaining the public’s trust. Blockchain is not only a new technology, it also comes with its own language, literally. There are numerous terms and definitions that accompany a person’s grasp of blockchain, and it can take some commitment of reading and learning to figure out. Not everyone is willing or able to do that. Continue reading...

Blockchains create an indisputable digital record that is decentralized, i.e, cannot be changed by a single actor. Using blockchain is generally for digital security. Here are  few reasons to use a blockchain: Tokenization A user can authenticate a unique physical item by pairing them with a corresponding digital token. In that sense, these tokens serve to connect the physical and digital worlds. With a token assigned to each physical good, that can revolutionize supply chain management, managing intellectual property to prevent against counterfeiting, and fraud detection.

Sidechains are blockchains which handle assets off of the main blockchain and are able to return them to the main blockchain at a future date. As you understand by now, blockchains are comprised of interconnected computers serving as nodes in a decentralized consensus network. Everything that happens to assets on that blockchain is validated and recorded on that blockchain. If assets are taken to another chain, however, where different protocols may apply to suit the needs of the parties using the assets, this may be called a sidechain. Continue reading...

Blockchains can validate, clear, and document transfers of value much faster and more securely than traditional methods. Blockchains offer an extremely efficient and reliable means of processing transactions of any size in a way that reduced the likelihood of fraud and failed payments. If a cryptocurrency wallet says that there is a specific balance present in a specific wallet, then that balance is there; it can be validated using the transaction record held on the thousands of computers on a b...

A Merkle Tree is a technique widely used to create the blocks in blockchains. When records of numerous transactions are blended together into a block and sent to a blockchain to be deciphered and validated, Merkle Trees are generally the design with which they are put together. Ralph Merkle first designed this hashing method in 1979 but didn’t see it popularized for some time. They are sometimes called hash trees. In case you are unaware, the difference between hashes and encryptions is that hashes are not intended to be decryptable unless someone has the original content. Hashes are basically symbols of a certain length generated using the “seed” of the actual content that was fed into the hash function. If the same content is entered as the seed, it will produce the same hash, but any differences will yield a completely different result. Continue reading...
