Blockchain

What is blockchain


A blockchain
is a continuously growing
list of records, called blocks,
which are
linked and secured
using cryptography.

Each block contains
typically
a hash pointer
as a link
to a previous block,
a timestamp
and
transaction data.

By design,
blockchains are inherently resistant
to modification of the data.

Functionally,
a blockchain can serve as
“an open, distributed ledger
that can record transactions
between two parties
efficiently
and
in a verifiable
and
permanent way.

Use case:
A resident in Dubai who is coming to Houston in the United States for orthopedic surgery and rehabilitation may need to carry more than the $10,000 cash allowed into the country on a tourist visit. Instead of bringing relatives or engaging in a costly bank transfer, he can invest in CareX and use his tokens to pay for the procedure upon arrival.

For healthcare providers,
this is as an opportunity to
expand their business.”

“The more patients
coming into a practice,
the cheaper the per patient costs,”

CareX is a blockchain platform on Ethereum blockchain.

Ethereum is an
open-source,
public,
blockchain-based
distributed computing
platform,

featuring
smart contract (scripting)
functionality.

Imagine when a doctor sees a patient
or writes a new prescription,
the patient agrees to have a reference or “pointer” added to a blockchain


a distributed access and validation system

using the blockchain to replace centralized intermediaries.
