MVP transaction from one group to another

All the things that are needed if I it should go according to my plan

Login-Server:

• Create user
• Check user email
• Generate key pair for users
• Private Key encrypted with user save password
• [-] Store passphrase encrypted with Server Admin Key, if user forgets password (currently stored unencrypted)
• Transaction to associate users with group
• Create transaction that links email to user-account/key pair
• [-] Create group and Hedera Topic and communicate to the node server
• Send users to the right community server depending on the group
• enter existing Hedera account optionally encrypted/unencrypted
• [-] create new Hedera account as payment account for transactions
• implement cross-group transaction missing

Community-Server

• Gradidos creation by privileged person
• general transfer interface
• Listing transactions
• Friend with other group (transaction on block chain)
• View current configuration of other groups
• public key of a user of another group to find the e-mail
• regular querying of transactions from one or more node servers
• implement cross-group transaction

Node-Server

• Create blockchains for each group/topic
• receive and store Hedera's transactions per group/topic
• verify transactions
• Query for users of another group via email hash
• Providing an interface for the Community Server to query the transactions
• Synchronization with other node servers
• Find other node servers via special Hedera transaction

Design the format of the cross-group transaction in detail, or check Paul's variant to see if it is suitable

A variant for quick success

Login-Server

• Install cross-group transaction
• Save your main Hedera account as a payment account unencrypted, I would only provide my Testnet account for this

Communtiy-Server

• manual querying of transactions from the node server by button
• Implement cross-group transaction
• Save login server of other groups in config
• Request for publickey to e-mail simply to all known login servers with existing interface

Node-Server

• Providing an interface for the community server to query the transactions

• Manual creation of the group (e.g. json-config)

• Creating a topic with Paul's python script

• Design the format of the cross-group transaction in detail, or check Paul's variant to see if it is suitable

• Set up a separate login server for each group

• Node servers must not fail, as Hedera saves each message for a maximum of 10 minutes
