The Manual

Architecture

• gui
• four internal mircoservers (auth, contact, market and message)
• core code module and lmdb
• one external i2p hidden service
• jwt for internal auth, jwp for external

JWP (JSON Web Proof)

• utilizes some external blockchain (neveko uses monero) for authorization of auth tokens
• 32 byte random signing keys generated on app start-up
• Hmac<Sha384> internal, Hmac<Sha512> external (jwp)
• see proof.rs eyJhbGciOiJIUzUxMiJ9.eyJhZGRyZXNzIjoiNThvaUJMQUtBQ3JaeTRqVnRYdUFXMzlCOW1zR3dlbVVkSm9HVlozcGdSY1RoWHZqWjZ0RERqRGpuOE1mTUZ5cEtZMlU1U1B6SkE3NnFHeHhDdjJzd1Y0NjhFYkI2dEsiLCJoYXNoIjoiNzRhOTM5NTU1Y2EyMWJmY2MxYzlhMjhlYjFkN2M5MWZiMjRhYzRiOTY4MDk2Yzg4ODU1ODA3ODcwMDA1NmQ2NiIsIm1lc3NhZ2UiOiIiLCJzaWduYXR1cmUiOiJPdXRQcm9vZlYyWHdYTEJYV0VtbXlWd3YyOHFQRWQ0Mk14bm1FNTU3aUFEVHFGNjZDWG9LQ1ZFeFBqTVU4NFNIeWprZmdLd01WZEI4OUZkTkJ5QUxyeU1ZamVxQlY1U0VtU0V4MUJWWE1ITVJNWHVuMzh5aWVtcWhCcmVSWUdpRGdMN1lmRmVmemJSTnhlIn0.gH4RlLrxu3xqxNvsHv7lX1yYomg07yTlv6VEKpDfXwbDV4O267CXzm30G4YBQOfuDf3xpegUmeVXOScPvIZVRw
• contents be decoded by 3rd parties but only the owner of the signing key can finalize the validation
• should be kept secret

Getting started

Adding a contact

• go to AddressBook in the gui
• enter .b32.i2p address of contact and click add
• if all goes well you will have imported their public neveko gpg app key
• dont reuse the app gpg keys anywhere else!
• don't forget to trust the contact with sign key in the check status window

Create JWP

• getting started the app will automatically generate an account and associated monero PRIMARY address. Only use it here to maintain privacy
• deposit some stagenet monero in your xmr account (address at top of gui screen)
• once unlocked neveko xmr balance will display
• click check status and Create JWP
• when authorizing to send to contact an invoice will be generated
• authorize payment and tx proof generation in the prompt
• this tx proof will be used to create an encrypted json web proof of payment with each contact
• think of it as a reusable, unforgeable coupon or ticket
• the invoice shows payment per blocks (time)
• default is 1 piconero per day
• the jwp is cached by the client until block time expiration at which time you will be required to authorize another payment

Sending a message

• the check status button will show current jwp for each contact
• clear stale jwp will purge data in case of timeout issues
• don't keep large amounts in neveko just enough for fees and jwps
• once a valid jwp is created (takes a few minutes) the compose button will be visible
• you need to click check status on contacts before sending to refresh jwp expiration check
• draft a plain text message, dont be shy
• verify recipient (.b32.i2p address) and press send
• plain text messages never leave your machine
• you can click Refresh button in the Mailbox to check for new messages
• messages must be decrypted by clicking decrypt

fts (failed-to-send)

• messages are automatically rebroadcasted every minute until either the contact comes back online or the JWP expires.
• If contacts don't come back online before JWP expiration the message must be drafted again
• It is primarily meant for handling connectivity issues or the edge case where a contact is is online during the check status but goes offline while the message is being drafted
