Double Spend
37
Suppose two transactions spend the same input to the same block.
Bitcoin automatically rejects both transactions to prevent one Bitcoin
from going toward two separate ends. A similar rejection occurs if two
separate blocks receive inputs from the same Bitcoin source. Bitcoin
treats such circumstances as incidents of accounting fraud.

Trust?
39
If I can agree that
once data is written into the Blockchain it is permanent and
that the Blockchain will have at least 1 copy still out there and
that you will only know it is me if I give you my key and
that no one owns it and
Understand that it would take more computing power and
precise timing than any one entity could ever own including the
largest data centers working together, a quantum computer, or
any government has; thus no bad actor could successfully hack
and change the data

Cryptlets are off-chain code modules that are written in any language that can
execute within a secure, isolated, trusted container and is communicated with over
secure channels. Cryptlets can be used in SmartContracts and UTXO systems
when additional functionality or information is needed, upgrading the blockchain
“oracle” approach with a Cryptlet and CryptoDelegate or adaptor.

Product Engineer
Product engineers at Hudson Morgan Blockchain are responsible for crafting a first-class developer experience for our platform. Their goal is to convey a complex system built on cryptography and distributed databases in a way that feels intuitive and inspires creativity. This means diving into frontend and backend code to build dashboards and other developer tools, as well as maintaining well-groomed APIs and documentation. It also includes creating prototypes that demonstrate how blockchain technology can enable a fundamentally new class of financial applications.
Candidates Need to have:Strong generalist programming ability. You learn quickly and strive for simplicity.A solid understanding of web application fundamentals. You can speak confidently about databases, application servers, browsers, and web security.Excellent communication skills. You speak and write with clarity, and have a high degree of empathy.Product instincts. You are eager to work alongside designers and PMs to produce the best user experience.Demonstrated ability to take ownership. You finish what you start and keep a high standard of quality.
It is nice, but not a requirement, to be familiar with:Ruby (and Rails)Frontend frameworks such as ReactUI/UX design toolsGoPostgres
We offer:Opportunity to work with smart teammates on ambitious technology that has concrete, real-world applicationsGenerous salary, equity, and benefitsA team culture that prioritizes inclusiveness and empathyExcellent work-life balance, including a flexible vacation policyA beautiful, tree-house style office in Hayes ValleyTeam lunch every dayGym/fitness reimbursements

Self-Sovereign identity
64
there’s a paradigm shift going on here, “going from the Facebooks
of the world, which make lots of money on our identity, to what
should be instead a world where we each have a self-sovereign
identity. We own a canonical persona with attributes and
attestations. When you sign into Facebook today, the company
owns your identity. But instead, if we own our own identity we could
get paid if we choose to look at an ad, for example. This is the
critical next point on the evolution of the Internet.”
