Lethean is decentralized (peer-2-peer) #VPN project with commercial gateway backed by the blockhain.
Lethean itself is the fuel and operating currency for this decentralized VPN. It is based on the CryptoNote technology and uses the exclusive CryptoNight v8 algorithm.
Following development and integration of VPN capabilities into the wallet Lethean ledger will allow any network user to act as a VPN exit node in exchange for #Lethean.

Key Features

Untraceable Payments:

Completely anonymous payment scheme using the ring signature technology which allows you to sign a message on behalf of
a group. The signature only proves the message was created by someone from the group. but all the possible signers are
indistinguishable from each other. A ring signature obscures identities because it only proves that a signer belongs to a group.

This allows a high level of anonymity in #cryptocurrency transactions. You can think of it as decentralized and trustless mixing.

Unlinkable Transactions:

Even if outgoing transactions are untraceable, everyone may still be able to see the payments you have received and thus
determine your income. However, by using a variation of the Diffie-Hellman exchange protocol, a receiver has multiple unique
one-time addresses derived from his single public key. After funds are sent to these addresses they can only be redeemed by
the receiver; and it would be impossible to cross-link these payments.

Double-Spending Proof:

Nobody is able to spend the same money twice — even if all his signatures are anonymous. Every signature contains a key image a kind of fingerprint of the secret key. It is based on a one-way cryptographic function: this implies that given only the
key image it is impossible to restore the corresponding secret key. These key images are used to prevent double-spending.

Blockchain Analysis Resistance:

Non-repeating one-time addresses and mixed keys in ring signatures rnake the whole blockchain resistant to analysis.
Each future transaction will only increase the entropy and create additional obstacles for an analyst.

Egalitarian Proof of Work:

The proof of work mechanism acts as a voting system. Thus, it is crucial that during the voting process all the participants
have equal voting privileges. CryptoNote brings this equality with its egalitarian proof of work, utilizing built-in CPU instructions,
which are very hard and too expensive to implement in special purpose devices, but perfectly suitable for ordinary PCs.

Adaptive Parameters:

A decentralized payment system must not depend on a single person’s decisions, even if this person is a developer. There are
no hard-coded constants; magic numbers in the code are designed to be re-calculated based on the previous state of the network.
Thus, they always change adaptively and independently, allowing the network to develop on its own.
