Walmart awarded patent for blockchain-based medical records system

U.S. retail giant Walmart has been awarded a patent for a system that would store medical records on a blockchain from a wearable device, according to a patent filing published by the U.S. Patent and Trademark Office.

The system, according to the document, will allow medical professionals to retrieve medical data from a patient that is unable to communicate. The patient’s medical records will theoretically be stored on a blockchain, accessible by a device worn by the patient that first responders could access with an RFID scanner. The patent further explains the principles of the system's operation:

“… receiving, by a processor of a computing system, an encrypted private key and a public key associated with the patient stored on a wearable device of the patient, in response to a scanning of the wearable device of the patient at a scene of an emergency, wherein the encrypted private key is decrypted by a biometric signature of the patient; obtaining, by the processor, the biometric signature of the patient by scanning a bodily feature of the patient; decrypting, by the processor, the encrypted private key using the biometric signature of the patient to determine a private key associated with the patient; and accessing, by the processor, the medical records of the patient, using a combination of the public key and the private key associated with the patient, to access a local storage medium of the wearable device.”

Additionally, the obtained medical information may be shared with hospitals and other healthcare entities, meaning that if the patient is transported from one medical care organization to another, their data will be available to medical care personnel before the patient’s arrival.

According to Fortune, Walmart is considering purchasing health insurer Humana, a company with which the retailer has an established relationship. Should the new blockchain medical record system prove viable, a partnership with Humana would provide an indispensable data depository.

Walmart has filed patents for other blockchain-based systems, including a marketplace for reselling purchased products, a “Smart Package” system to track package contents, environmental conditions, location, and other details, and an electrical grid that will be powered by Bitcoin or other digital currencies. The company’s vice president Frank Yiannas said that Walmart is ready to use blockchain technology in its live food business, which will shorten the time it takes to track produce from six days to two seconds.

These 27 Companies Support Bitcoin Unlimited, 44 Oppose

While bitcoin Unlimited is gaining traction among miners, only a handful of bitcoin companies are in favor of its bigger block and Emergent Consensus proposal.


Breakdown by Company

The scaling debate in which two predominant bitcoin improvement proposals, SegWit and bitcoin Unlimited, are competing for miners’ support is becoming more and more intense.

As the debate escalates, supporters from both sides are now threatening to push for user activated forks (both soft and hard). While bitcoin Unlimited is considered the most popular proposal in terms of hashing power, a look at the companies that support it or SegWit reveals the exact opposite.

As of this writing, out of the companies listed in Coin Dance, 66 support SegWit and 58 are ready for it. Only 8 companies oppose SegWit.

On the BU side, there are 27 in favor, with 9 companies ready for it. This means that 70% of companies actively support SegWit, compared to 20% for BU. The other 10% are undecided or “unknown”. The companies that support BU include:

  • AntPool
  • Atlanta bitcoin
  • BitAddress.org
  • bitcoin.com (Saint Bitts LLC)
  • BitcoinPlug
  • Bitmain
  • BTCPOP
  • Canoe
  • Coinucopia
  • GoUrl.io
  • bitcoin WordPress/PHP Gateway
  • Keys4Coins
  • MrCoin
  • Slon BTM
  • Bitfire.io
  • Bittoku GK
  • btc.top
  • GBMiners
  • Keyois
  • Prohashing
  • Satoricoin
  • ViaBTC
  • Bitzillions
  • Magnr
  • Bitaps.com
  • CTY bitcoin Vietnam TNHH
  • OKCoin
  • Trezor (Ready)
  • Electrum (Ready)
  • bitcoin Wallet for Android (Ready)
  • Bifinex (Ready)
  • Breadwallet (Ready)
  • Gemini (Ready)
  • Lamassu (Ready)
  • Rocketr (Ready)

It should be noted that even among the 9 companies that are ready for BU, two also support SegWit (Electrum and Trezor) and 5 are ready for SegWit (including Bitfinex and Gemini). 

It’s also worth noting that some of the companies that are against bitcoin Unlimited are not even supporting SegWit. They are simply opposed to BU’s Emergent Consensus.

Meanwhile, 4 of the 8 companies that oppose SegWit and are all signaling for BU are mining pools.

Who Supports What?

We can see that some predominant exchanges like Poloniex, LocalBitcoins, CoinCheck and others are ready for SegWit, while other names like BTCC, Xapo and Bitso support it.

On the BU side, in addition to bitcoin.com, Magnr, BitAddress.org, and several BTM providers, the biggest names by far are mining pools such as Bitmain’s Antpool, ViaBTC and GBMiners. However, the independence of these mining pools has recently come under question by the community.

At the same time, the only major exchanges that support BU also support SegWit, including OKCoin, Bitfinex (ready) and Gemini (ready).

The companies that actively oppose SegWit include 4 mining pools and 4 other small companies that don’t have much bearing in the bitcoin ecosystem. Conversely, among the companies that oppose BU actively, we find names like BitGo, Vaultoro, Bitsquare, and GreenAddress.

Among the undecided, we still have names like Bitstamp, Bittrex, Bitmex, Kraken, and others.

bitcoin Businesses Generally Against BU, Hard Fork

The general animosity towards bitcoin Unlimited can also be observed in the industry letters that have been signed so far. For example, a list of nearly 20 exchanges has signed a hard fork contingency plan in which the BU token would be listed as BTU or XBU.

Canada’s bitcoin ecosystem has also produced an industry letter in which a large number of economic nodes operators signaled their rejection for BU and proposed industry guidelines for hard forks.

Moreover, the data is also reflected (despite varying data depending on the course) by the share of bitcoin Core (84-91%) nodes among total network nodes compared to bitcoin Unlimited’s (2-9%).

The conclusion that can be draw from this data is that despite the growing popularity of bitcoin Unlimited among mining pools, bitcoin companies as well as user nodes are largely opposed to the bitcoin Unlimited proposal.
