@robomed - you will be interested that in September 2016, there was a national Blockchain in Healthcare Workshop in Washington DC, jointly sponsored by ONC (Office of the National Coordinator for Healthcare IT)  and NIST (National Institute of Standards and Technology). Over 90 papers were submitted for presentation, and 70 of them were published by ONC, and 15 of them received monetary awards for further development. Institutions submitting projects for consideration included MIT, Mayo Clinic, UCSD, UCLA, Deloitte, Cigna, IBM, Merck, Accenture, Intel, Accenture. Also many projects were proposed by independent healthcare providers and developers. Here is a link to the 70 publications:

There was also a Blockchain in Healthcare Code-A-Thon at Georgetown University in April 2017, links to further info:

As an attendee at the Sept 2016 Workshop, I noted that most of the projects were to promote private, permissioned blockchains, for the use of individual healthcare institutions. Personally, I think a more valuable approach would be the development of public blockchains for the use of all patients and healthcare providers.

The project I am working on uses an existing, established public blockchain to allow users to delegate permissions for existing health portals privately:  between patients, healthcare providers, and other caregivers, adhering to HIPAA standards. The desired outcome of the project is to preserve existing health IT infrastructure (such as existing EHR systems, and existing data and imaging storage), but leverage mandated health IT portals and EHR API’s so that apps can be created that collate heath data universally across multiple platforms.

hey @X-ray thanks -- can you recheck that link, it just loops back to this thread.
surprising to me that no one implemented on the main net yet. regardless of the debate about implementing for btc it seems to me that it is an important innovation to test in real time
there are hundred of altcoins

This is just a fact-finding mission.

Which altcoins have already implemented segwit in their active mainnet?

Same question for multisig and p2sh, although that is another angle on the same question.

Ha I guess I am the old man in the room. When I started with crypto it was just:

1. Bitcoin (sha256)
2. Litecoin (scrypt)
3. Namecoin (sha256, merged mining, decentralized DNS)

That was it. Total landscape. Life was simple.

I bought 4,000 ETH back during the presale in 2014, with an idea to take a nap and come back in 10 yrs to see how it was doing. I have never touched the coins, never even opened a wallet.

Do I now own 4,000 ETC? or 4,000 ETH? or 4,000 of both ??

Hey a nickel is a nickel (unless it is a bitnickel)

It sounds like you are trying to find a way to send a btc transaction in exchange for something but cannot be assured of delivery. In this case you will want to use a trusted third party for escrow. Some alt coins are developing escrow built - in to the wallet, such as syscoin

publicly disclosed signature vs behind closed doors with media?
you decide.

Remember the Voyager "Golden Record"? Burn a copy of the blockchain + software and launch it to deep space.

Or better yet, convince NASA it would be a good idea to put nodes on all the various planetary probes going up.

OP great list. Interesting that you are promoting NXT but it did not make the list.  Seems like an honest statement.

I am thinking of just an encrypted token for use by an OAuth Provider. Not sure how many bytes that would be. I would have thought that one of the wallet apps would have taken advantage of this field by now.

One can easily insert a public note into a transaction, but it is not encrypted. It would be useful to encrypt small amounts of data in this field, such that only the recipient of the transaction can decrypt it, using their own private key.

Any current wallets support this? (I am aware of bitmessage, but that is a different blockchain. I am only talking about the btc blockchain, not alts).

Crazy promotion idea. Instead of on bank notes, write the keys (and QR's) inside of a few candy wrappers of a particular brand of chocolate. Make it for a substantial amount of btc value, not just dust, and only a few wrappers. It would be like Charlie and the Chocolate Factory, but in real life. What a huge marketing boon for that chocolate company, they would want the business frenzy and therefore would fund the large reward.

   

@morantis

Just noticed this thread. Here is what I would throw into the idea mill. I am sure someone has thought of this before, but I have never seen it written about.

They have these "CoinStar" machines everywhere where you can get rid of your piles of change, and convert them into gift cards for merchants, or coupons. It would be great to use this vast infrastructure to convert all this change into btc paper wallets.

I'm sure this would be already happening except for the regulatory issues involved.

either way, when btc = $199 usd, debate over

At least Russia has standards.
In the U.S. someone patented the entire web and sued.

Microsoft seems to want every blockchain in existence on its Azure cloud platform, EXCEPT bitcoin blockchain. They have even announced partnerships with Lisk and others that have not even been launched yet. Are they waiting for RootStock?  . . .  or something else???

As if this finding needed additional symmetry, the Association for Computing Machinery, in whose journal that 1969 paper on auto traffic flowing in and out of 10-meter blocks of road was published, just this past year awarded it's Turing Award to Whitfield Diffie and Martin E. Hellman for fundamental contributions to modern cryptography.

The “Live Free or Die” state also has the highest real-estate-property-tax-rate (2.1%) of any state in the union (except for two others). This is to offset the lack of income and sales tax in the state.

It looks like Azure is planning to test way more than three blockchains.

They are partnering so far with Ethereum, Ripple, Syscoin, Emercoin, Eris, CoinPrism, BitPay, Augur, Slock.it, and Lisk. Just a partial list, and some of these are DApps based on Ethereum.
