[SDC] ShadowCash | Welcome to the UMBRA

Hey guys, you're probably going to get more from the Shadowcash Twitter than you are here. Its good to see enthusiastic tweets https://twitter.com/SDCoin


The longer the silence, the bigger the news.

I had a crazy idea last night about how to make Shadowsend messages invulnerable to future decryption by other than the recipient.

The weakness is that all nodes on the network receive all messages. So the spy could be receiving and recording all of them, unable to decrypt them now, but in 10 or 1000 years from now, maybe.

A one-time pad is a very old, low-tech, and unbreakable for of encryption, unbreakable because the key is longer than the message and using any of the possible pads can make the coded message decrypt to any clear message you want. The weakness there is that the OTP is a private key and both parties have to have prior contact to exchange the key.

So what if... when one wallet sends a Shadowsend message to another, it also send a OTP (also encrypted with Shadowsend), to the recipient along with a few hundred other random nodes, and the OTP is used in addition to the public-key encryption to encrypt and decrypt the message? Nodes other than the intended recipient would ignore it just like any other Shadowsend message. The chances of the spy intercepting both the message and the OTP are low, and he would need to defeat the public-key encryption on both to read the message.

In addition to this, all online wallets would randomly send out random OTP's to random nodes on the network, so most of the pads the spy would be intercepting would be garbage but he would have to decrypt them all anyway, not knowing which ones are garbage and which can be used to decrypt a real message.

Of course users exchanging very sensitive information are already able to send each other a pad ahead of time using Shadowsend, but having random wallets also doing it randomly would add a twist that makes it much more complicated to defeat.

code: Hi Automatic Monkey,

I swiftly looked for your idea and quickly realized what you were aiming for. The golden standard for asynchronous encrypted messaging solutions is Signal's protocol, which provides both future secrecy and forward secrecy. In general you could say that it's combination of OTR's ratchet and SCIMP (Silent Circles Instant Messaging Protocol). I can provide you with more information about that, I've studied it for some time now.. The hardest part is integrating it securely, you don't want to constantly write temporary keys to persistent storage And Bitcoin is more like: 'write all keys to storage so we never lose one'..

Would the ShadowCash community like a faucet?  TheCryptoChat would be willing to host one.

Hehe, who made that typo?  Greed lol.

[jupiter00000]

I think it's meant to be a subconscious suggestion to a course of action:

Accumulation.

I bought my SDC a couple of months ago  Looking forward for Aphrodite release.

Hi,
what is the diffrence between this coin and zcash that will be lauched on the 28th of October?

[rutherford]

code: Shadow is a total package. ZCash only provides only one small piece of the puzzle, namely financial anonymity. We provide anonymous communication through encrypted messaging in a decentralized manner (no IP address linked to messages and nobody can read them).  We also provide financial anonymity and if there is demand we will dig into the technical details of it.

code: Centralized services are just ticking time bombs, if I remember correctly   XMR doesn't even have multisig support for the moment which means bye bye money.

Lol in one short post you totally discredited yourself by comparing a centralized DNM to a decentralized one. Have you ever even used AlphaBay or similar markets? They're horribly inefficient, difficult for new users, and fraught with exit scams and FBI take overs..

Yes xmr does not support multisig so you have to trust your money to someone who may run away with that money anytime!!!

Notice his motto is "Trust no one". He obviously doesn't understand what he is saying...

Very good points!

There doesn't seem to be much happening here, I thought there was going to be an update?

There was actually an update the other day. Here is the blog post link: https://blog.shadowproject.io/2016/08/21/where-are-we-at-let-me-tell-you/
