Moderated by Dan Reecer, Community and Growth, Polkadot & Kusama at Web3 Foundation
Transcription compiled by Theresa Boettger, Polkadot Ambassador:
Dieter Fishbein, Ecosystem Development Lead, Web3 FoundationDan: Hey everyone, thanks for joining us for the Polkadot Launch AMA. We have Dieter Fishbein (Head of Ecosystem Development, our business development team), Logan Saether (Technical Education), and Will Pankiewicz (Master of Validators) joining us today.
We had some great questions submitted in advance, and we’ll start by answering those and learning a bit about each of our guests. After we go through the pre-submitted questions, then we’ll open up the chat to live Q&A and the hosts will answer as many questions as they can.
We’ll start off with Dieter and ask him a set of some business-related questions.
Dieter could you introduce yourself, your background, and your role within the Polkadot ecosystem?Dieter: I got my start in the space as a cryptography researcher at the University of Waterloo. This is where I first learned about Bitcoin and started following the space. I spent the next four years or so on the investment team for a large asset manager where I primarily focused on emerging markets. In 2017 I decided to take the plunge and join the space full-time. I worked at a small blockchain-focused VC fund and then joined the Polkadot team just over a year ago. My role at Polkadot is mainly focused on ensuring there is a vibrant community of projects building on our technology.
Q: Adoption of Polkadot of the important factors that all projects need to focus on to become more attractive to the industry. So, what is Polkadot's plan to gain more Adoption? [sic]A (Dieter): Polkadot is fundamentally a developer-focused product so much of our adoption strategy is focused around making Polkadot an attractive product for developers. This has many elements. Right now the path for most developers to build on Polkadot is by creating a blockchain using the Substrate framework which they will later connect to Polkadot when parachains are enabled. This means that much of our adoption strategy comes down to making Substrate an attractive tool and framework. However, it’s not just enough to make building on Substrate attractive, we must also provide an incentive to these developers to actually connect their Substrate-based chain to Polkadot. Part of this incentive is the security that the Polkadot relay chain provides but another key incentive is becoming interoperable with a rich ecosystem of other projects that connect to Polkadot. This means that a key part of our adoption strategy is outreach focused. We go out there and try to convince the best projects in the space that building on our technology will provide them with significant value-add. This is not a purely technical argument. We provide significant support to projects building in our ecosystem through grants, technical support, incubatoaccelerator programs and other structured support programs such as the Substrate Builders Program (https://www.substrate.io/builders-program). I do think we really stand out in the significant, continued support that we provide to builders in our ecosystem. You can also take a look at the over 100 Grants that we’ve given from the Web3 Foundation: https://medium.com/web3foundation/web3-foundation-grants-program-reaches-100-projects-milestone-8fd2a775fd6b
Q: On moving forward through your roadmap, what are your most important next priorities? Does the Polkadot team have enough fundamentals (Funds, Community, etc.) to achieve those milestones?A (Dieter): I would say the top priority by far is to ensure a smooth roll-out of key Polkadot features such as parachains, XCMP and other key parts of the protocol. Our recent Proof of Authority network launch was only just the beginning, it’s crucial that we carefully and successfully deploy features that allow builders to build meaningful technology. Second to that, we want to promote adoption by making more teams aware of Polkadot and how they can leverage it to build their product. Part of this comes down to the outreach that I discussed before but a major part of it is much more community-driven and many members of the team focus on this.
We are also blessed to have an awesome community to make this process easier 🙂
Q: Where can a list of Polkadot's application-specific chains can be found?A (Dieter): The best list right now is http://www.polkaproject.com/. This is a community-led effort and the team behind it has done a terrific job. We’re also working on providing our own resource for this and we’ll share that with the community when it’s ready.
Q: Could you explain the differences and similarities between Kusama and Polkadot?A (Dieter): Kusama is fundamentally a less robust, faster-moving version of Polkadot with less economic backing by validators. It is less robust since we will be deploying new technology to Kusama before Polkadot so it may break more frequently. It has less economic backing than Polkadot, so a network takeover is easier on Kusama than on Polkadot, lending itself more to use cases without the need for bank-like security.
In exchange for lower security and robustness, we expect the cost of a parachain lease to be lower on Kusama than Polkadot. Polkadot will always be 100% focused on security and robustness and I expect that applications that deal with high-value transactions such as those in the DeFi space will always want a Polkadot deployment, I think there will be a market for applications that are willing to trade cheap, high throughput for lower security and robustness such as those in the gaming, content distribution or social networking sectors. Check out - https://polkadot.network/kusama-polkadot-comparing-the-cousins/ for more detailed info!
Q: and for what reasons would a developer choose one over the other?A (Dieter): Firstly, I see some earlier stage teams who are still iterating on their technology choosing to deploy to Kusama exclusively because of its lower-stakes, faster moving environment where it will be easier for them to iterate on their technology and build their user base. These will likely encompass the above sectors I identified earlier. To these teams, Polkadot becomes an eventual upgrade path for them if, and when, they are able to perfect their product, build a larger community of users and start to need the increased stability and security that Polkadot will provide.
Secondly, I suspect many teams who have their main deployment on Polkadot will also have an additional deployment on Kusama to allow them to test new features, either their tech or changes to the network, before these are deployed to Polkadot mainnet.
Logan Saether, Technical Education, Web3 Foundation
Q: Sweet, let's move over to Logan. Logan - could you introduce yourself, your background, and your role within the Polkadot ecosystem?A (Logan): My initial involvement in the industry was as a smart contract engineer. During this time I worked on a few projects, including a reboot of the Ethereum Alarm Clock project originally by Piper Merriam. However, I had some frustrations at the time with the limitations of the EVM environment and began to look at other tools which could help me build the projects that I envisioned. This led to me looking at Substrate and completing a bounty for Web3 Foundation, after which I applied and joined the Technical Education team. My responsibilities at the Technical Education team include maintaining the Polkadot Wiki as a source of truth on the Polkadot ecosystem, creating example applications, writing technical documentation, giving talks and workshops, as well as helping initiatives such as the Thousand Validator Programme.
Q: The first technical question submitted for you was: "When will an official Polkadot mobile wallet appear?"A (Logan): There is already an “official” wallet from Parity Technologies called the Parity Signer. Parity Signer allows you to keep your private keys on an air-gapped mobile device and to interactively sign messages using web interfaces such as Polkadot JS Apps. If you’re looking for something that is more of an interface to the blockchain as well as a wallet, you might be interested in PolkaWallet which is a community team that is building a full mobile interface for Polkadot.
For more information on Parity Signer check out the website: https://www.parity.io/signe
Q: Great thanks...our next question is: If someone already developed an application to run on Ethereum, but wants the interoperability that Polkadot will offer, are there any advantages to rebuilding with Substrate to run as a parachain on the Polkadot network instead of just keeping it on Ethereum and using the Ethereum bridge for use with Polkadot?A (Logan): Yes, the advantage you would get from building on Substrate is more control over how your application will interact with the greater Polkadot ecosystem, as well as a larger design canvas for future iterations of your application.
Using an Ethereum bridge will probably have more cross chain latency than using a Polkadot parachain directly. The reason for this is due to the nature of Ethereum’s separate consensus protocol from Polkadot. For parachains, messages can be sent to be included in the next block with guarantees that they will be delivered. On bridged chains, your application will need to go through more routes in order to execute on the desired destination. It must first route from your application on Ethereum to the Ethereum bridge parachain, and afterward dispatch the XCMP message from the Polkadot side of the parachain. In other words, an application on Ethereum would first need to cross the bridge then send a message, while an application as a parachain would only need to send the message without needing to route across an external bridge.
Q: DOT transfers won't go live until Web3 removes the Sudo module and token holders approve the proposal to unlock them. But when will staking rewards start to be distributed? Will it have to after token transfers unlock? Or will accounts be able to accumulate rewards (still locked) once the network transitions to NPoS?A (Logan): Staking rewards will be distributed starting with the transition to NPoS. Transfers will still be locked during the beginning of this phase, but reward payments are technically different from the normal transfer mechanism. You can read more about the launch process and steps at http://polkadot.network/launch-roadmap
Q: Next question is: I'm interested in how Cumulus/parachain development is going. ETA for when we will see the first parachain registered working on Kusama or some other public testnet like Westend maybe?A (Logan): Parachains and Cumulus is a current high priority development objective of the Parity team. There have already been PoC parachains running with Cumulus on local testnets for months. The current work now is making the availability and validity subprotocols production ready in the Polkadot client. The best way to stay up to date would be to follow the project boards on GitHub that have delineated all of the tasks that should be done. Ideally, we can start seeing parachains on Westend soon with the first real parachains being deployed on Kusama thereafter.
The projects board can be viewed here: https://github.com/paritytech/polkadot/projects
Dan: Also...check out Basti's tweet from yesterday on the Cumulus topic: https://twitter.com/bkchstatus/1270479898696695808?s=20
Q: In what ways does Polkadot support smart contracts?A (Logan): The philosophy behind the Polkadot Relay Chain is to be as minimal as possible, but allow arbitrary logic at the edges in the parachains. For this reason, Polkadot does not support smart contracts natively on the Relay Chain. However, it will support smart contracts on parachains. There are already a couple major initiatives out there. One initiative is to allow EVM contracts to be deployed on parachains, this includes the Substrate EVM module, Parity’s Frontier, and projects such as Moonbeam. Another initiative is to create a completely new smart contract stack that is native to Substrate. This includes the Substrate Contracts pallet, and the ink! DSL for writing smart contracts.

Will Pankiewicz, Master of Validators, Parity Technologies
Q: (Dan) Thanks for all the answers. Now we’ll start going through some staking questions with Will related to validating and nominating on Polkadot. Will - could you introduce yourself, your background, and your role within the Polkadot ecosystem?A (Will): Sure thing. Like many others, Bitcoin drew me in back in 2013, but it wasn't until Ethereum came that I took the deep dive into working in the space full time. It was the financial infrastructure aspects of cryptocurrencies I was initially interested in, and first worked on dexes, algorithmic trading, and crypto funds. I really liked the idea of "Generalized Mining" that CoinFund came up with, and started to explore the whacky ways the crypto funds and others can both support ecosystems and be self-sustaining at the same time. This drew me to a lot of interesting experiments in what later became DeFi, as well as running validators on Proof of Stake networks. My role in the Polkadot ecosystem as “Master of Validators” is ensuring the needs of our validator community get met.
Q: Cool thanks. Our first community question was "Is it still more profitable to nominate the validators with lesser stake?"A (Will): It depends on their commission, but generally yes it is more profitable to nominate validators with lesser stake. When validators have lesser stake, when you nominate them this makes your nomination stake a higher percentage of total stake. This means when rewards get distributed, it will be split more favorably toward you, as rewards are split by total stake percentage. Our entire rewards scheme is that every era (6 hours in Kusama, 24 hours in Polkadot), a certain amount of rewards get distributed, where that amount of rewards is dependent on the total amount of tokens staked for the entire network (50% of all tokens staked is currently optimal). These rewards from the end of an era get distributed roughly equally to all validators active in the validator set. The reward given to each validator is then split between the validators and all their nominators, determined by the total stake that each entity contributes. So if you contribute to a higher percentage of the total stake, you will earn more rewards.
Q: What does priority ranking under nominator addresses mean? For example, what does it mean that nominator A has priority 1 and nominator B has priority 6?A (Will): Priority ranking is just the index of the nomination that gets stored on chain. It has no effect on how stake gets distributed in Phragmen or how rewards get calculated. This is only the order that the nominator chose their validators. The way that stake from a nominator gets distributed from a nominator to validators is via Phragmen, which is an algorithm that will optimally put stake behind validators so that distribution is roughly equal to those that will get in the validator set. It will try to maximize the total amount at stake in the network and maximize the stake behind minimally staked validators.
Q: On Polkadot.js, what does it mean when there are nodes waiting on Polkadot?**A (Will):**In Polkadot there is a fixed validator set size that is determined by governance. The way validators get in the active set is by having the highest amount of total stake relative to other validators. So if the validator set size is 100, the top 100 validators by total stake will be in the validator set. Those not active in the validator set will be considered “waiting”.
Q: Another question...Is it necessary to become a waiting validator node right now?A (Will): It's not necessary, but highly encouraged if you actively want to validate on Polkadot. The longer you are in the waiting tab, the longer you get exposure to nominators that may nominate you.
Q: Will current validators for Kusama also validate for Polkadot? How strongly should I consider their history (with Kusama) when looking to nominate a good validator for DOTs?A (Will): A lot of Kusama validators will also be validators for Polkadot, as KSM was initially distributed to DOT holders. The early Kusama Validators will also likely be the first Polkadot validators. Being a Kusama validator should be a strong indicator for who to nominate on Polkadot, as the chaos that has ensued with Kusama has allowed validators to battle test their infrastructure. Kusama validators by now are very familiar with tooling, block explorers, terminology, common errors, log formats, upgrades, backups, and other aspects of node operation. This gives them an edge against Polkadot validators that may be new to the ecosystem. You should strongly consider well known Kusama validators when making your choices as a nominator on Polkadot.
Q: Can you go into more details about the process for becoming a DOT validator? Is it similar as the KSM 1000 validators program?A (Will): The Process for becoming a DOT validators is first to have DOTs. You cannot be a validator without DOTs, as DOTs are used to pay transaction fees, and the minimum amount of DOTs you need is enough to create a validate transaction. After obtaining enough DOTs, you will need to set up your validator infrastructure. Ideally you should have a validator node with specs that match what we call standard hardware, as well as one or more sentry nodes to help isolate the validator node from attacks. After the infrastructure is up and running, you should have your Polkadot accounts set up right with a stash bonded to a controller account, and then submit a validate transaction, which will tell the network your nodes are ready to be a part of the network. You should then try and build a community around your validator to let others know you are trustworthy so that they will nominate you. The 1000 validators programme for Kusama is a programme that gives a certain amount of nominations from the Web3 Foundation and Parity to help bootstrap a community and reputation for validators. There may eventually be a similar type of programme for Polkadot as well.
Dan: Thanks a lot for all the answers, Will. That’s the end of the pre-submitted questions and now we’ll open the chat up to live Q&A, and our three team members will get through as many of your questions as possible.
We will take questions related to business development, technology, validating, and staking. For those wondering about DOT:
DOT tokens do not exist yet. Allocations of Polkadot's native DOT token are technically and legally non-transferable. Hence any publicized sale of DOTs is unsanctioned by Web3 Foundation and possibly fraudulent. Any official public sale of DOTs will be announced on the Web3 Foundation website. Polkadot’s launch process started in May and full network decentralization later this year, holders of DOT allocations will determine issuance and transferability. For those who participated in previous DOT sales, you can learn how to claim your DOTs here (https://wiki.polkadot.network/docs/en/claims).
Telegram Community Follow-up Questions Addressed Below
Q: Polkadot looks good but it confuses me that there are so many other Blockchain projects. What should I pay attention in Polkadot to give it the importance it deserves? What are your planning to achieve with your project?A (Will): Personally, what I think differentiates it is the governance process. Coordinating forkless upgrades and social coordination helps stand it apart.
A (Dieter): The wiki is awesome - https://wiki.polkadot.network/
Q: Over 10,000 ETH paid as a transaction fee , what if this happens on Polkadot? Is it possible we can go through governance to return it to the owner?A: Anything is possible with governance including transaction reversals, if a network quorum is reached on a topic.
A (Logan): Polkadot transaction fees work differently than the fees on Ethereum so it's a bit more difficult to shoot yourself in the foot as the whale who sent this unfortunate transaction. See here for details on fees: https://w3f-research.readthedocs.io/en/latest/polkadot/Token%20Economics.html?highlight=transaction%20fees#relay-chain-transaction-fees-and-per-block-transaction-limits
However, there is a tip that the user can input themselves which they could accidentally set to a large amount. In this cases, yes, they could proposition governance to reduce the amount that was paid in the tip.
Q: What is the minimum ideal amount of DOT and KSM to have if you want to become a validator and how much technical knowledge do you need aside from following the docs?A (Will): It depends on what the other validators in the ecosystem are staking as well as the validator set size. You just need to be in the top staking amount of the validator set size. So if its 100 validators, you need to be in the top 100 validators by stake.
Q: Will Web3 nominate validators? If yes, which criteria to be elected?A (Will): Web 3 Foundation is running programs like the 1000 validators programme for Kusama. There's a possibility this will continue on for Polkadot as well after transfers are enabled. https://thousand-validators.kusama.network/#/
You will need to be an active validator to earn rewards. Only those active in the validator set earn rewards. I would recommend checking out parts of the wiki: https://wiki.polkadot.network/docs/en/maintain-guides-validator-payout
Q: Is it possible to implement hastables or dag with substrate?A (Logan): Yes.
Q: Polkadot project looks very futuristic! But, could you tell us the main role of DOT Tokens in the Polkadot Ecosystem?A (Dan): That's a good question. The short answer is Staking, Governance, Bonding. More here: http://polkadot.network/dot-token
Q: How did you manage to prove that the consensus protocol is safe and unbreakable mathematically?A (Dieter): We have a research teams of over a dozen scientists with PhDs and post-docs in cryptography and distributed computing who do thorough theoretical analyses on all the protocols used in Polkadot
Q: What are the prospects for NFT?A: Already being built 🙂
Q: What will be Polkadot next roadmap for 2020 ?A (Dieter): Building. But seriously - we will continue to add many more features and upgrades to Polkadot as well as continue to strongly focus on adoption from other builders in the ecosystem 🙂
A (Will): https://polkadot.network/launch-roadmap/
This is the launch roadmap. Ideally adding parachains and xcmp towards the end of the year
Q: How Do you stay active in terms of marketing developments during this PANDEMIC? Because I'm sure you're very excited to promote more after this settles down.A (Dan): The main impact of covid was the impact on in-person events. We have been very active on Crowdcast for webinars since 2019, so it was quite the smooth transition to all-online events. You can see our 40+ past event recordings and follow us on Crowdcast here: https://www.crowdcast.io/polkadot. If you're interested in following our emails for updates (including online events), subscribe here: https://info.polkadot.network/subscribe
Q: Hi, who do you think is your biggest competitor in the space?A (Dan): Polkadot is a metaprotocol that hasn't been seen in the industry up until this point. We hope to elevate the industry by providing interoperability between all major public networks as well as private blockchains.
Q: Is Polkadot a friend or competitor of Ethereum?A: Polkadot aims to elevate the whole blockchain space with serious advancements in interoperability, governance and beyond :)
Q: When will there be hardware wallet support?A (Will): Parity Signer works well for now. Other hardware wallets will be added pretty soon
Q: What are the attractive feature of DOT project that can attract any new users ?A: https://polkadot.network/what-is-polkadot-a-brief-introduction/
A (Will): Buidling parachains with cross chain messaging + bridges to other chains I think will be a very appealing feature for developers
Q: According to you how much time will it take for Polkadot to get into mainstream adoption and execute all the plans set for this project?A: We are solving many problems that have held back the blockchain industry up until now. Here is a summary in basic terms:
Q: When will bitpie or imtoken support DOT？A: We are working on integrations on all the biggest and best wallet providers. ;)
Q: What event/call can we track to catch a switch to nPOS? Is it only force_new_era call? Thanks.A (Will): If you're on riot, useful channels to follow for updates like this are #polkabot:matrix.org and #polkadot-announcements:matrix.parity.io
A (Logan): Yes this is the trigger for initiating the switch to NPoS. You can also poll the ForceEra storage for when it changes to ForceNew.
Q: What strategy will the Polkadot Team use to make new users trust its platform and be part of it?A (Will): Pushing bleeding edge cryptography from web 3 foundation research
A (Dan): https://t.me/PolkadotOfficial/43378
Q: What technology stands behind and What are its advantages?A (Dieter): Check out https://polkadot.network/technology/ for more info on our tech stack!
Q: What problems do you see occurring in the blockchain industry nowadays and how does your project aims to solve these problems?A (Will): Governance I see as a huge problem. For example upgrading Bitcoin and making decisions for changing things is a very challenging process. We have robust systems of on-chain governance to help solve these coordination problems
Q: How involved are the Polkadot partners? Are they helping with the development?A (Dieter): There are a variety of groups building in the Polkadot ecosystem. Check out http://www.polkaproject.com/ for a great list.
Q: Can you explain the role of the treasury in Polkadot?A (Will): The treasury is for projects or people that want to build things, but don't want to go through the formal legal process of raising funds from VCs or grants or what have you. You can get paid by the community to build projects for the community.
A: There’s a whole section on the wiki about the treasury and how it functions here https://wiki.polkadot.network/docs/en/mirror-learn-treasury#docsNav
Q: Any plan to introduce Polkadot on Asia, or rising market on Asia?**A (Will):**We're globally focused
Q: What kind of impact do you expect from the Council? Although it would be elected by token holders, what kind of people you wish to see there?A (Will): Community focused individuals like u/jam10o that want to see cool things get built and cool communities form

Block.co third webcast ” Blockchain in Healthcare: Bridging Trust in response to COVID-19“ received amazing feedback! We gathered some of the best experts in the field, Georgina Kyriakoudes, Ahmed Abdulla, Dimitri Neocleous, Dr. Alice Loveys to share their experience in the industry and discuss with us the latest updates in the sphere of Healthcare! In its third series of webcasts, Block.co gathered 253 people watching the event from 59 different countries, for a 90-minute webcast where guests answered participants’ questions.
Below is a list of the questions that were made and were not answered due to time constraints during the Blockchain in Healthcare webcast. Please note that the below information is only for educational purposes!
Question 1: I like what Dimitrios was saying regarding ownership and transfer. Health and social care have invested much in Information Management systems and processes. Transfer between NHS and social care is a typical block. Can you elaborate on how the blockchain sits across that – leapfrogs yet goes with the grain of what is already there in terms of shared records protocols, the exponentially growing types of professionals, pharmacists, careers, etc. that need early access to these records for better decision making.
Block.co Team Answer: Blockchain technology has the potential to improve healthcare, placing the patient at the center of the health care ecosystem, while providing security, privacy, and interoperability of health data. Blockchain could provide a new model for health information exchanges and transform electronic medical records to be more efficient, disintermediated, and secure. While it is not a cure, this new, Blockchain in Healthcare rapidly evolving field provides a sandbox for experimentation, investment, and proof-of-concept testing.
Healthcare systems around the world are preparing road maps that define critical policy and technical components needed for nationwide interoperability, including:
Blockchain technology creates distinctive opportunities to scale back complexity, improve trustless collaboration, and create secure and immutable data. National Healthcare Systems need to track this rapidly evolving field to identify trends and sense the areas where government support may be needed for the technology to realize its full potential in health care. To form blockchain’s future, they ought to take into account mapping and gathering the blockchain ecosystem, establishing a blockchain framework to coordinate early-adopters, and supporting a pool for dialogue and discovery.
Question 2: What about the “compatibility” of blockchain solutions in healthcare with GDPR and/or other regulations about personal data protection.
Block.co Team Answer: The General Data Protection Regulation (GDPR), Europe’s new framework for data protection laws, has a vital impact on healthcare organizations. During this more and more patient-centric world where global healthcare organizations collect a large set of data on patients to produce improved health outcomes, this increased regulation has an even larger impact.
GDPR presents challenges across all industries and includes language that has a special impact on healthcare. The regulation defines “personal” data as “any information relating to an identified or identifiable natural person (data subject); an identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person.” On top of this definition, GDPR contains three extra, important definitions that pertain to health data:
However, healthcare organizations that usually manage health data, have an added responsibility to take care of “data concerning health,” “genetic data,” and “biometric data” to a higher standard of protection than personal data, in general. GDPR prohibits the processing of these forms of health data unless one of the three conditions below would apply as per Article 9.
a. The data subject must have given “explicit consent.”
b. “Processing is necessary for the purposes of preventive or occupational medicine, for the assessment of the working capacity of the employee, medical diagnosis, the provision of health or social care or treatment or the management of health or social care systems and services …”
c. “Processing is necessary for reasons of public interest in the area of public health, such as protecting against serious cross-border threats to health or ensuring high standards of quality and safety of health care and of medicinal products or medical devices …”
Consent VS Explicit Consent – If one pays attention, there’s a difference in the GDPR’s health data use conditions (calls for “explicit consent”) and the general definition (calls for “consent”). Thus, there’s an ongoing debate as to what constitutes the difference between “unambiguous” and “explicit” consent. Despite the debate and the final legal clarifications, there is no doubt that in the purposes of the healthcare the “explicit consent” must have the strongest agreement form listing in detail the use(s) of data and covering the cases of data transfers and storage.
Question 3: How can we use blockchain technology by the government in Africanflavored government, say by Ministry of health to have patient autonomy of medical records that can be accessed by any government hospital irrespective of the ailment and record printed by the previous hospital and doctor, such as referral cases without having to open a new file in the referred hospital.
Block.co Team Answer: Perhaps that would be an ideal implementation of the Block.co solution issuing a digital certificate of medical examination on an Open Public Blockchain such as the Bitcoin blockchain, that would be decentralized in nature, easy to validate online without any special wallets, and would be provided by the patient on-demand, to refer to treatments received in other hospitals or areas. But this would require that the practitioner is aware and can use the open-source code or use Block.co services to issue these certificates. Alternatively, there could be the use of a wallet to store these medical credentials to be submitted on demand to health practitioners. Moreover, there would need to be an alignment of regulation in the matter as decentralized repositories are not recognized at the moment.
Question 4: Is there any data breach threat in the blockchain using a poorly protected private key at communication?
Block.co Team Answer: Millions of health care records have already been breached, and in attempts to combat this issue, solutions often result in the inaccessibility of health records. Health providers often send information to other providers, and this often ends up in mishandling of data, losing records, or passing on inaccurate and old data. In some cases, only one copy of an updated health record exists, and this may result in the loss of information. Health records often contain personal information such as names, social security numbers, and home addresses. When it comes to Blockchain in Healthcare, a poorly protected private key is always a factor to consider. A private key allows us to sign a transaction and spend funds residing in an address (public key) by providing ownership with the signature. It is a unique string of information that represents proof of identification inside the blockchain, which includes the right to access and control the participant’s wallet. It must be kept secret, as it is effectively a personal password. In the case that that private key is poorly protected, there is always a data breach threat.
Question 5: The medical record of a patient is owned by the patient. What happens if a doctor accesses the record without the consent of the patient? Using the smart contract, could there be a governing body, say a legal system that can call the doctor to order?
Block.co Team Answer: Rather than having each physical and electronic copies of records, blockchains may enable the shift to electronic health records (EHR). When looking at Blockchain in Healthcare, medical records on the blockchain would be within the management of the patient rather than a third party, through the patients’ private and public keys. Patients may then control access to their health records, making transferring information less cumbersome. Because blockchain ledgers are immutable, health information may not be deleted or tampered with. Blockchain transactions would be accompanied by a timestamp, permitting those with access to maintain updated information. The doctor would not be able to access the record without the consent of the patient. A patient would need to sign the transaction in a smart contract in order to transfer patient details to the doctor.
Question 6: So, how are private data protected when the patient is simply notified that unauthorized access just took place on her medical record? and, how are the negative results of this breach rectified towards the patient?
Block.co Team Answer: The patient would be notified to sign a transaction enabling access to the party requesting access to the specific medical record. In other cases, there could be a multi-signature wallet requiring multiple transactions in the cases where the patient may need assistance, for example, when underage or when not in a healthy state of mind, or being non-responsive or in critical condition. The patient needs to be responsible for his own data and be empowered through awareness and know-how of this technology. With great power, comes also great responsibility, although it is yet a challenge to enable computer illiterate people to interact with this technology.
Question 7: Can the same record of a patient still be shared with private hospitals and say another government/private hospital abroad on the same blockchain?
Block.co Team Answer: Depending on whether the information is on a public blockchain or a private blockchain. When on a private blockchain, they will need to be granted permission to access the blockchain accordingly.
Question 8: No one has directly spoken about ownership where a large research institution/ consortium is working with the data – it is not solely the person who has said so…
Block.co Team Answer: Indeed, it is solely not the person who has a say so. Technology may be used in both evil and good ways and it is still the obligation and responsibility of people within governments to ensure human liberties and rights are preserved when utilizing such powerful technologies such as blockchain and sometimes the combination of blockchain with AI, IoT, and biometrics. Blockchain in Healthcare, in the same way, that it can empower individuals and increase their standard of living and prosperity, at the same time, it can also empower corrupt governments with alternative agendas and totalitarian states. Block.co believes it is most important for people to be educated around the matter and be able to form a voice and movement to safeguard their human liberties and rights, hence our continuous effort on discussing these matters with our community and providing education, powered by the pioneers in the space, the University of Nicosia.

The IQ.cash project team has already developed for their investors the IQ Masternode network that they use. Also, the IQ coin is presented on such well-known exchanges as HitBTC, BitHumb Glogal, P2PB2B, CoinsBit, BitForex, CREX24 and Mercatox. Therefore, traders can easily trade it! If an investor has more than 3000 IQ on his balance sheet, then he can receive passive income 57% of the block, miners, in turn, receive 43% of the block. We still have 6%, which are reserved for DAO (decentralized autonomous organizations), that is, they are used to invest, for example, in ICO projects, websites, trading bots, and improving the entire IQ ecosystem . cash and so on. All of these unique features can help make the IQ.cash platform popular around the world. You may come to this article to find out about the massive passive income, but worth noting that you should know what it is about. Think about it, investing money to something vague is very risky. Thus, what is IQ cash? To make it brief, this is another cryptocurrency that has quite clear and potential income. Just like bitcoin, this IQcash has a potential fluctuation which increases and give great passive income through the magnificent distribution splits. It is also easy to say that IQ cash is an investment master nodes Cryptocurrency which is open for everyone. In this matter, whether it is for investors, traders, or even miners. Yes, those who are familiar with the world of cryptocurrency are the target of this project. The main task is to provide instant anonymous online payment along with the investing system. The IQ cash platform ecosystem work as DAO (decentralized Autonomous Organization.
One thing that makes this digital money gain quite a lot of participants in the available wallets. Not a real physical wallet, but one to store all your cryptocurrency. In this case, the wallet is available for Windows, Linux, and Mac. You can choose one that fits with the equipment you have. Along with that, you can install the masternode on your home pc or Linux VPS. Your masternode will just do the earning rewards, without all the other extra features. If you want to install, you can use PC running windows Mac or even Linux. However, on VPS you have to use Linux with Ubuntu 16.04 version. Other than that, there are some requirements you have to fulfill. The first one is having a 3000 IQ or more on balance. Even 3001 coin is acceptable. Then, use only one PC for dedicated IP-address and also a 24/7 network connectivity (network loos less than 30 – 60 mins) without any interrupted operating system. Security - it is the most considered aspect of investment, as we know that investing in cyberspace is very risky. Therefore, IQ.Cash presents the security of investor accounts, where all accounts cannot be blocked and, most importantly, account funds can only be accessed by the account holder. Masternodes - how do we know IQ. Cash uses the PoW consensus algorithm that supports the Masternode system. this certainly adds to the intrinsic value of this project, which economically can add a value of approximately 43% and indirectly increases passive income by around 57% for all participants in the masternode. Masternode provides network integrity. Transaction anonymity and transaction speed. Of course, to run a masternode system, everyone can only invest 3000 IQ and then immediately enjoy the results obtained with this IQ.Cash masternode feature. Anonymity of the transaction - this is more about the privacy of the transaction itself. where users can completely trust the system. and you don’t have to worry about data access by irresponsible parties. because the system automatically encrypts data when transferring and receiving assets
The IQ.cash platform operates on the basis of the POW consensus with support for a system such as MASTERNODE. And this is very cool, since this system makes the project more interesting and attractive for crypto enthusiasts. Indeed, thanks to the MASTERNODE system, miners receive 43% from mining, and people who own MASTERNODE receive a passive income of 57%. MASTERNODE supports the network, i.e. data privacy, transaction anonymity and speed, and much more. To become the owner of MASTERNODE you need to have more than 3000 IQ on your balance sheet. Anonymity. Transaction anonymity is provided by the PrivateSend algorithm. Users can feel safe and not worry about their assets. Since this system perfectly encrypts data. Therefore, you can safely send and receive any crypto assets. ASIC RESISTANCE. This technology is struggling with such a serious problem as a significant acceleration in the growth of network complexity. IQ network . cash works on the basis of the NeoScrypt algorithm, which is struggling with this problem. High transaction speed. Such an instant transaction speed, because the InstantSend algorithm works. Just think about it, the transaction speed is only about five seconds. Absolute decentralization. Affect both participants and crypto assets of the IQ network . cash no one can. Because everything will be safe, reliable and transparent.
Only requires a transaction speed of only about 5 seconds / transaction. And all transactions are done instantly, so this will provide a very efficient way of working for the users later. more and more projects have started to appear, whose actions are directed to one of the niches of our daily activities. This is excellent, we have been waiting for this for many years, but at the moment, strange as it may seem, projects aimed exclusively at the crypto industry have become a minor order of magnitude. It was simply impossible to take it. And now a project has appeared on the horizon that positions its activities exclusively as a useful product for mining companies, investors and even traders. As it turned out, the team has a work product, whose currency is traded on many major exchanges. That's good luck, I smiled and started to study the IQ.cash project and its capabilities. Go back to the main interface and choose a personal tab (bottom right corner). Then, move to the next phase by choosing the Fee & Payment tab. You will see fee balance, FLS, BTC fee deposit address, and other information. In here, copy the IQ.cash wallet address in the FLS address tab. To move on to the next stages, you should have bought the required number of IQ cash (3000 IQ cash) beforehand. You can buy the IQ cash masternode from the official sites.
