What is Blockchain?
Even though the original Bitcoin blockchain was designed to operate democratically without interference or influence from banks or central regulators, blockchain technology can still operate within closed parameters. This means a bank or company could implement their own blockchain, and control which transactions are added to the chain. It will still be a secure system, but like the traditional banking system it will be based on trust of the decision-maker.
These are permissioned systems which, in the case of Corda and Hyperledger, restrict access to transaction data to the parties involved in that transaction, rather than the data being made public in a public ledger like Bitcoin. Understand how Facebook leveraged specific aspects of blockchain technology to launch a new cyrptocurrency called Libra, and its potential impact on the banking and finance sector. Walmart has developed a blockchain system based on Hyperledger Fabric to trace the provenance of their products.
The blockchain allows suppliers to upload certificates of authenticity to the ledger securely, bringing more trust to a system and enabling the company to trace products back to source within seconds rather than days. After successful trials with two products, the company is looking to roll it out further.
BurstIQ 's big data blockchain platform helps patients and doctors securely transfer sensitive medial information using smart contracts that establish the parameters of what data can be shared. In April , the streaming giant Spotify acquired blockchain startup Mediachain in an effort to create a fairer, more transparent, and rewarding music industry for musicians.
Prior to its acquisition, Mediachain had developed several technologies that could aid in these efforts, including a decentralized, peer-to-peer database that connects applications to media and information about it, the Mediachain Attribution Engine, and a cryptocurrency that rewards artists for their work.
The all-in-one real estate transaction management software, Propy , leverages blockchain technology to streamline real estate transactions and mitigate the risk of fraud. Propy even offers properties that can be purchased using cryptocurrency.
With the ability to self-diagnose and heal possible breaches, it leverages blockchain technology to manage billions of devices and protects industrial IoT operations against cyber attacks. Shipping giant DHL is at the forefront of blockchain-powered logistics. One of the largest shipping companies to embrace blockchain, it uses the technology to maintain a digital ledger of shipments and protect the integrity of transactions.
And several banks and insurance companies, such as JP Morgan and MetLife , are using their own private blockchains to simplify, streamline and verify transactions and contracts that would previously have taken far longer and potentially been less secure.

Privacy and blockchain
Blockchain is an emerging technology that has been around for less than 10 years, yet its surge in popularity over the past couple of years has been remarkable. Being initially launched as the technology powering bitcoin, it has since been through several evolutions by different projects. It was not long after bitcoin was released that blockchain started being experimented with to solve more than just transfer of value, something the Ethereum platform arguably achieved with considerable success. But with that also came discussions about private blockchain networks, particularly from businesses and enterprises that were keen to leverage smart contracts, albeit not at the expense of having all information made public. The public blockchain, sometimes referred to as trustless or permissionless blockchain, is undoubtedly the one most are familiar with. More than just being transparent by being public, it is publicly distributed so that anyone can effectively set up their own node on the network by downloading and maintaining a copy of the ledger, not much different from any other peer-to-peer network. Not only can anyone read all the data contained within the ledger, but they are also free to send transactions over it as well as contribute towards authorising transactions and achieving consensus.
Difference between private and public blockchain
Blockchain, the distributed ledger technology underlying bitcoin, may prove to be far more valuable than the currency it supports. Each party on a blockchain has access to the entire database and its complete history. No single party controls the data or the information. Every party can verify the records of its transaction partners directly, without an intermediary. Communication occurs directly between peers instead of through a central node. Each node stores and forwards information to all other nodes. Every transaction and its associated value are visible to anyone with access to the system. Each node, or user, on a blockchain has a unique plus-character alphanumeric address that identifies it. Users can choose to remain anonymous or provide proof of their identity to others. Transactions occur between blockchain addresses.
Private Blockchain vs Public Blockchain
A public blockchain has an open network and all the information is available in the public domain. As this blockchain is not bound by any rules and permissions, any party can view and write data on the blockchain, making the data is accessible to all. Public blockchains are also decentralized and immutable. Once an entry is made on the blockchain, it cannot be altered or deleted after the entries are validated.
Public Vs. Private Blockchain
Blockchains come in many different shapes and sizes. Depending on the application, one type of blockchain may work better than the other. The key difference between public and private blockchains is the level of permission users have when interacting with the blockchain. It may be the case that anyone should have access to a blockchain, which in that case a public blockchain would work well. Public blockchains are the most well-known since virtually all cryptocurrencies are public blockchains. With a public blockchain, anyone in the world can read, write, and participate in the blockchain.
Public vs. Consortium vs. Federated vs. Private Blockchain
To take advantage of it you must choose the right type of network. Blockchain, trust, decentralization, Bitcoin, transparency, anonymity, blockchain, blockchain, blockchain. These words seem to appear randomly on the Web regardless the theme of an article you read. Do you wonder how banking can benefit from blockchain? No worries, some projects already do it — just search for the use cases. Since when Satoshi Nakamoto published a white paper considering Bitcoin and blockchain technology, the latter gained fame as a tool for combating trust issues and bringing transparency to transactions between independent participants. Even though a decade passed, for a lay public, blockchain is still not the easiest concept to deal with.
Blockchain is a unique ingenious technology that can be used virtually everywhere ranging from payment system development to dealing with the Internet of Things IoT. Some people even call it "the new Internet. However, there's another more thing to keep in mind: no two blockchains are alike. Knowledge of key features of different blockchain types can make life a lot easier for a crypto investor or business owner willing to deal with a cryptocurrency.
All over the world, conversations with respect to the multi-faceted prospects and use cases of the blockchain technology in business are trending. We have previously detailed diverse use cases a business could explore as they position for the future. We have also analyzed different blockchain platforms that could be utilized in building blockchain applications. We now proceed to help you make an informed choice between deploying a private or public blockchain. Just before we dive in, it is befitting at this stage to address the common confusion between blockchain and DLTs. A DLT Distributed Ledger Technology is a decentralized form of database managed by multiple participants, across multiple nodes.
For supply-chain organisations launching new blockchain projects, one of the most fraught considerations typically is whether to use a public or private ledger, and with what permission models. In and , the World Economic Forum dove deeply into the evolving discussion on whether public or private blockchains are typically best suited for the supply chain industry. Key findings of this body of research include:. Being aware of the pros and cons of blockchain and understanding where its features really help to solve a problem will help to prevent the new technology from becoming merely an expensive version of a centralised database. These seven questions are typically important in deciding which blockchain structure to use for a particular project. Note, this list is not intended to provide a final authoritative answer, but to assist in a rapid initial analysis.
Blockchain, the underlying technology behind cryptocurrencies like Bitcoin, is quickly gaining popularity in the digital space. More and more companies are recognizing its revolutionary potential and are choosing to adopt this new technology for their daily operations, making blockchain less of a buzzword and more of a forward-thinking mantra. A community of users controls how this information is edited and updated, and all blocks are chained together chronologically. While more organizations are becoming aware of the applications for blockchain in the enterprise , there is less familiarity with the differences between public and private blockchains.
