In a proof-of-concept study, transaction processing speed is expected to be only a few hundredths of the conventional way, such as credit card. Considering that the number of transactions in the healthcare sector is enormous, a blockchain technology revolution is needed. It is a theoretical but possible risk and a clear solution for this should be suggested [ 2 ]. Many believe that blockchain technology can change medicine and beyond, but no one sees evidence to support their belief.

It will be challenging to train them on tech at this stage. Devices and sensors will expand a new home healthtech work force. Kevin Clauson: From the beginning, healthcare has actively tried to dissociate blockchain and bitcoin.

While the desire to do so is understandable because of the murky history of bitcoin and cryptocurrencies in the public consciousness and the disruption-resistant, risk-averse nature of the healthcare industry, it is still a mistake to do so. It is a mistake if the intent is to understand and evaluate blockchain in the broader healthcare industry. The cryptocurrency market is still a substantial driver for companies building at the intersection of blockchain and healthcare— particularly for startups. This trend in will lead to healthcare companies demonstrating better resourced efforts in leveraging blockchain and distributed ledger technology DLT as well as superior organization, integration, and hopefully impact.

Vikram Dhillon: Fitness wearables are producing an enormous amount of data that can be captured in actionable formats. Scheduling timely exports of such data allows better understanding of how patients implement lifestyle changes for chronic diseases such as diabetes. Committing snapshots of these data to the blockchain can incentivize and reward lifestyle changes. With the microtransaction payment structure built into the blockchain, rewards programs can be turned into smart contracts that dispatch reward tokens to wallets on blockchain. As more healthcare providers and partners join such a network, the tokens will have more value and be redeemable for discounts such as co-pay for clinic visits.

Blockchain will be deployed across the healthcare industry to improve secure healthcare data sharing toward the goal of precision medicine, accelerating research, and improving healthcare outcomes.

This will include use cases in personal health records, wearables, lab sample data management, supply chains, and research. In September , the Institute of Electrical and Electronic Engineers IEEE published that it is sponsoring initiatives with technology and healthcare leaders around the world, including device manufacturers, pharmaceutical companies, providers, and regulators, to enable standards for clinical Internet of Things device and data interoperability with blockchain, as well as lab sample data tracking and management with blockchain.

We are working together to define new standards, create real demonstration pilots, and deliver the value blockchain has to offer. This will be analogous to the proliferation of the intranets or personal computers, as opposed to the mainframe or blockchain as a computer for the world. The club blockchain will exclude non-members and ensure non-rivalrous benefits to the members.

Anh L. More to the point, blockchain will likely be intertwined with other aspects of technological advances such as artificial intelligence AI , Internet-of-Things, and mobile applications for ease of adoption and use. I believe the blockchain will permeate several aspects of healthcare, with first adoptions occurring in areas involving financial transactions. Those include micropayments deductibles, prescriptions, traditional cash pay , insurance processing and claims, and payments and quality assurance involving medical supply chain management.

These are areas where high friction, massive inefficiencies, and costs can be reduced with a new way of managing trust in a transaction. Other areas of healthcare that can involve adoption of blockchain include physician credentialing, patient consent management, and, of course, medical records.

Of note, medical records have a long way to go since medical data are very resource-intensive and will require creative measures to limit the impact of large data on stakeholders on the blockchain platforms. Dennis A. Porto: In the coming year, the distinction between enterprise blockchains and public blockchains will begin to blur.

These large public blockchains, especially bitcoin, have best captured what makes blockchains valuable: trust minimization and tamper resistance approaching the notional ideals of trustlessness and immutability. Enterprise blockchains will exist perhaps as sidechains to or layers above bitcoin, where they can periodically settle on the main bitcoin blockchain without being encumbered by scaling issues characteristic of a public cryptocurrency. We will see serious efforts to create and capture value in healthcare blockchain: pharmaceutical supply chain management, opioid and cannabis diversion control, physician credentialing, as well as clinical trial and patient data management.

We will also see a number of projects fail despite their good intentions. Successful projects will be those that have a narrow use of blockchain to solve a problem that is impossible with a traditional database. Finally, innovation will continue to occur at the protocol level. I anticipate that proof of work will continue to dominate, and that the most impactful technical innovations will focus on optimizing this particular consensus mechanism.

Distributed Ledger Technology: An umbrella term used to describe technologies that distribute records or information e. Internet-of-Things: The interconnection via the Internet of computing devices embedded in everyday objects, enabling them to send and receive data. Monero: An open-source cryptocurrency created in April that focuses on fungibility, privacy and decentralization. Monero uses an obfuscated public ledger, meaning anybody can broadcast or send transactions, but no outside observer can tell the source, amount or destination.

PokitDok, Inc. Proof-of-Work PoW : A system protocol or function that is an economic measure to deter denial of service attacks and other service abuses such as spam on a network, by requiring some work from the service requester, usually meaning processing time by a computer. Public Blockchain: A permissionless blockchain. Anyone can join the blockchain network, meaning that they can read, write, or participate. The Proof of Work PoW consensus algorithm involves solving a computational challenging problem in order to create new blocks, referred to as mining.

It is the most commonly used consensus algorithm to date. The problem is solved by randomly guessing a value for a nonce, which is added to a hashed block, and when rehashed, meets the difficulty level restrictions.

What is blockchain for?

When a miner finds a solution, the miner creates a block and broadcasts the nonce to the network, finalizing that block. The winner receives a reward in the form of payment such as tokens. Since its first use in , such an attack has rarely been successful but are becoming more regular.

With the Proof of Stake PoS algorithm, nodes are considered validators rather than miners, where nodes validate each transaction in order to earn a transaction fee. Nodes place a stake of their own assets, and the block forger is randomly selected from all of the nodes with staked assets. The selection process is weighted based on the size of the stake, so a user that stakes twice as much as another user is twice as likely to be called to validate the block. The PoS algorithm saves the need to obtain a large amount of computational resources used in mining under the PoW consensus algorithm.

The technology is designed so any changes to data on a block are easily detectable to the network, giving blockchain a capability called immutability. Since all of the blocks are chained together, each block including the previous hash, a malicious actor that wishes to change data in a block would need to gain control of the majority of nodes in the network. They would then need to also recalculate all of the subsequent chained hashes, which would require control and collusion on an impractical scale, especially as networks grow large, and may also require an enormous amount of computing power, depending on the consensus algorithm.

This also means that the past history of the data on the blockchain also persists and cannot be changed or deleted. Updates are added as new blocks as an append-only mechanism rather than as an overwrite.

Background

This has significant performance ramifications when dealing with information that frequently changes, with each change requiring a new transaction. This also has significant ramifications from a privacy, security, and compliance standpoint where a blockchain may contain sensitive information such as personally identifiable information PII. The entire history is visible and stored in an immutable and verifiable way, and new blocks and the transactions within those blocks are visible near real-time across the network, giving blockchain a characteristic of transparency.

There are permissioned and private networks versus permissionless and public networks that control the network access, the visibility of data in shared ledgers within, and therefore the level of transparency. Since data are immutable, the blockchain supports a network where nodes can operate in a trustless system.

Blockchain Technology Could Revolutionize Health Care

This means that nodes do not have to trust each other or establish a way to ensure trust, as long as they trust the blockchain, the associated consensus algorithm, and the data on-chain. Cryptography is used to remove the burden of trust from intermediaries to cryptographic algorithms for data validation. Certain permissioned implementations may also use a central authority to provide access and identity management.

The P2P network and redundancy of data lend itself to a high level of fault tolerance. This means that nodes can be added or deleted from the network, and still the overall network remains in operation, and the consistency, validity, integrity and immutability of the data is ensured. The technology is designed to have Byzantine Fault Tolerance, which refers to the idea that even if nodes are untrusted, the network must come to a consensus on the official state of the blockchain.

Currently, private networks are more mature than public networks for healthcare. Certain use cases are seeing traction with adoption.
