Paid for 4xUSFM codes, but shoppy doesn't seem to be noticing my Ethereum payment (wrote you on Telegram too).

// All resolved now, thanks!

2x$100 codes worked, thanks!

I want a TEST PILOT CODE

Worked like a charm, thanks!

Hey,

I've bought two RC ones, but selly didn't send me the email, and their support is not responding.

Do you get copies of their receipts wrt who got which codes and what are the order IDs? May can solve from your side

Уcaтoгo нa вac нeт!

Oh wow, you replaced the not working one. Awesome!

Bought 4 codes, only 3 worked. Given the price, I am happy enough with that though

Update:

• Business primer
• Whire paper added

NuCypher KMS: Decentralized key management system

We’re excited to share NuCypher KMS, a decentralized key management system (KMS) for public blockchains. With NuCypher KMS, an entirely new set of decentralized applications is unlocked for developers. Use cases requiring secure storage, sharing, and manipulation of private data can now be built on public blockchains, allowing for greater protection and control of private data.
The post below gives an overview and a detailed description can be found in our draft technical white paper.

What
NuCypher KMS provides encryption and cryptographic access controls, without reliance on a central service provider. It leverages state-of-the-art proxy re-encryption technology to allow re-keying encrypted data. This allows a decentralized network of nodes to provide key management operations, without accessing private keys or plaintext data.

How
The core technology is proxy re-encryption (PRE), a cryptographic primitive which allows a third-party proxy to transform ciphertexts from one public key to another (using re-encryption keys), without learning anything about the underlying message.

Main actors and interactions in a PRE environment
This ability to securely delegate access to private, encrypted information, makes PRE an ideal candidate for constructing cryptographic access controls for distributed systems such as blockchain, internet of things (IoT), and big data.
In NuCypher KMS, access controls are issued, enforced, and revoked via smart contracts executed by a decentralized network of re-encryption nodes. This network controls re-encryption keys and allows data owners to conditionally grant and revoke access to third-parties based on their public key.
Re-encryption nodes are incentivized to behave properly using a proof-of-stake NKMS token. If the nodes are malicious or defective, their deposit is forfeit. Correctly behaving nodes are incentivized to provide re-encryption services through payment in NKMS.

Use cases
NuCypher KMS enables public blockchains to securely store and manipulate secrets, giving decentralized applications a way to work with private data. But key management as a service is useful for centralized applications, too.
Potential use cases include:

• KMS-as-a-service for handling secrets in AWS instances (similar to Hashicorp Vault, Amazon Key Management etc);
• Safely storing encrypted secrets alongside code on GitHub;
• Decentralized Digital Rights Management (DDRM);
• Pay-to-view streaming;
• Encrypted digital content marketplaces;
• Private multi-user chats;
• Private, shareable file storage;
• Patients sharing medical records with healthcare providers;
• Blind identity management;
• Mobile device management and revocation.

Call for contributions
We’re very interested in the community’s suggestions and comments on the technical white paper — everything from security to token economics to functionality requests. We’re also excited to brainstorm use cases for NKMS and would love to hear your ideas. Your involvement will help inform the final, revised version of the white paper.

You can find a draft of the technical white paper and the GitHub repo.

Hi bitcointalk lenders / borrowers!

We’re (michwill and maclane) working on a decentralized crowdlending network called LoanCoin:

• As a saver, you buy LoanCoin, a crytpoasset giving you a claim on a portfolio of loans. Interest and principal repaments are reinvested into new loans with the goal of generating consistent and stable increases in value.
• When you borrow money, you can collateralize your loan with digital assets (loancoin or bitcoin for now, more exotic smart property in the future). This collateral can be posted by you or co-signers (people or groups who trust you).
• Loan officers are individuals or groups responsible for finding borrowers and selecting who will receive loans from the capital pool. They’re savvy lenders who have the time and expertise to identify good loans.
• If a borrower does not have appropriate digital collateral, loan officers can either vouch/cosign for the borrower or take possession of physical collateral from said borrower and post digital collateral as a proxy.

The final goal is to make credit scalable without spending tons of money on “bank branches”. Anybody can be a “branch” and make money on it, without any one node having the ability to systematically defraud the system.

We have some more info on our website: http://getloancoin.com

And a high-level infographic: http://getloancoin.com/img/LoanCoinInfographic.png

Do you guys think something like this could work? What problems/obstacles do you see? For those of you who are active lenders on here, would you be interested in being a loan officer by coinvesting LoanCoin capital along with your existing funds?

Thanks!

Yes, that was totally unexpected. They wrote the news without even talking to us :-)

What's wrong with using BTC to transfer money for a loan denominated in USD (at a current price)?

Thanks for the response!

At the moment we have a centralized version running privately, however we plan on making it decentralized, trustless and unstoppable, just like Bitcoin :-)

Hi bitcointalk!

We’re pre-announcing LoanCoin: a decentralized bank / crowdlending network:

• As a lender, you buy a coin giving you a claim on a portfolio of loans. Interest revenue is re-invested into new loans with the goal of generating consistent and stable increases in value.
• When you borrow money, you can collateralize your loan with digital assets (loancoins or bitcoins for now, more exotic smart property in the future). This collateral can be posted by you or co-signers (people or groups who trust you).
• If you know which people won't default, you can co-sign for them and earn interest on your collateral.

Our vision is to make LoanCoin decentralized and trustless but for the time being, we’re running a centralized version on top of Counterparty. Whether you want to use the Counterparty-based prototype or wait for the trustless decentralized version, you can request an invite for early access. (Due to the recent FinCen/SEC rulings, we’re making sure all our legal/regulatory ducks are in a row before officially launching.)
