 ## Disclaimer
 
-This is WIP implementation of SimpleX chat that implements a new network topology for asynchronous communication combining the advantages and avoiding the disadvantages of federated and P2P networks.
+SimpleX Chat implements a new network topology for asynchronous communication combining the advantages and avoiding the disadvantages of federated and P2P networks.
 
-If you expect a software being reliable most of the time and doing something useful, then this is probably not ready for you yet. We do use it for terminal chat though, and it seems to work most of the time - we would really appreciate if you try it and give us your feedback.
+[SimpleXMQ security model](https://github.com/simplex-chat/simplexmq/blob/master/protocol/overview-tjr.md) had many improvements in v1.0.0; the implementation has not been audited yet.
 
-**Please note:** The main differentiation of SimpleX network is the approach to internet message routing rather than encryption; for that reason no sufficient attention was paid to either TCP transport level encryption or to E2E encryption protocols - they are implemented in an ad hoc way based on RSA and AES algorithms. See [SMP protocol](https://github.com/simplex-chat/simplexmq/blob/master/protocol/simplex-messaging.md#appendix-a) on TCP transport encryption protocol (AEAD-GCM scheme, with an AES key negotiation based on RSA key hash known to the client in advance) and [this section](https://github.com/simplex-chat/simplexmq/blob/master/rfcs/2021-01-26-crypto.md#e2e-encryption) on E2E encryption protocol (an ad hoc hybrid scheme a la PGP). These protocols will change in a consumer ready version to something more robust.
+We use SimpleX Chat all the time, but you may find some bugs. We would really appreciate if you use it and let us know anything that needs to be fixed or improved.
 
 ## Network topology
 
-SimpleX is a decentralized client-server network that uses redundant, disposable nodes to asynchronously pass the messages via message queues, providing receiver and sender anonymity.
+SimpleX is a client-server network that uses redundant, disposable nodes to asynchronously pass messages via message queues, providing receiver and sender anonymity.
 
 Unlike P2P networks, all messages are passed through one or several (for redundancy) servers, that do not even need to have persistence (in fact, the current [SMP server implementation](https://github.com/simplex-chat/simplexmq#smp-server) uses in-memory message storage, persisting only the queue records) - it provides better metadata protection than P2P designs, as no global participant ID is required, and avoids many [problems of P2P networks](https://github.com/simplex-chat/simplex-chat/blob/master/simplex.md#comparison-with-p2p-messaging-protocols).
 
-Unlike federated networks, the participating server nodes do NOT have records of the users, do NOT communicate with each other, do NOT store messages after they are delivered to the recipients, and there is no way to discover the full list of participating servers - it avoids the problem of metadata visibility that federated networks suffer from and better protects the network, as servers do not communicate with each other. Each server node provides unidirectional "dumb pipes" to the users, that do authorization without authentication, having no knowledge of the the users or their contacts. Each queue is assigned two RSA keys - one for receiver and one for sender - and each queue access is authorized with a signature created using a respective key's private counterpart.

-sqlite3 ~/.simplex/smp-chat.db
+```sh
+curl -o- https://raw.githubusercontent.com/simplex-chat/simplex-chat/master/message_views.sql | sqlite3 ~/.simplex/simplex_v1_chat.db
 ```
 
-Now you can query `messages` table, for example:
+Open SQLite Command Line Shell:
 
-```sql
-select * from messages
-where conn_alias = cast('alice' as blob)
-  and body like '%cats%'
-order by internal_id desc;
+```sh
+sqlite3 ~/.simplex/simplex_v1_chat.db
 ```
 
+See [Message queries](./message_queries.md) for examples.
+
 > **Please note:** SQLite foreign key constraints are disabled by default, and must be **[enabled separately for each database connection](https://sqlite.org/foreignkeys.html#fk_enable)**. The latter can be achieved by running `PRAGMA foreign_keys = ON;` command on an open database connection. By running data altering queries without enabling foreign keys prior to that, you may risk putting your database in an inconsistent state.
 
-## Future roadmap
+**Convenience queries**
+
+Get all messages from today (`chat_dt` is in UTC):
+
+```sql
+select * from all_messages_plain where date(chat_dt) > date('now', '-1 day') order by chat_dt;
+```
+
+Get overnight messages in the morning:
+
+```sql
+select * from all_messages_plain where chat_dt > datetime('now', '-15 hours') order by chat_dt;
+```
+
+## Roadmap
 
 1. Mobile and desktop apps (in progress).
 2. SMP protocol improvements:
-    - SMP queue redundancy and rotation.
-    - Message delivery confirmation.
-    - Support multiple devices.
+   - SMP queue redundancy and rotation.
+   - Message delivery confirmation.
+   - Support multiple devices.
 3. Privacy-preserving identity server for optional DNS-based contact/group addresses to simplify connection and discovery, but not used to deliver messages:
-    - keep all your contacts and groups even if you lose the domain.
-    - the server doesn't have information about your contacts and groups.
+   - keep all your contacts and groups even if you lose the domain.
+   - the server doesn't have information about your contacts and groups.
 4. Media server to optimize sending large files to groups.
 5. Channels server for large groups and broadcast channels.

+# Simplex chat
+
+**Published:** Oct 22, 2020
+
+https://simplex.chat
+
+I'd really appreciate your feedback, criticism and suggestions on the open-source idea I was slowly working on since early 2020. I recently made the demo server for the low-level message queue protocol ("simplex messaging protocol") and the website to try to explain the chat idea that would use this protocol.
+
+Haskell protocol implementation: https://github.com/simplex-chat/simplexmq
+
+In short, the protocol defines a minimalist set of commands and server responses (just 7 commands and 5 responses sent over TCP) to operate encrypted message queues with in-memory persistence - the implementation uses STM.
+
+If anything, it was definitely helping to get to know Haskell types etc. much deeper than before :)
+
+Any criticism would be great - thank you in advance!

+## Announcing SimpleX Chat Prototype!
+
+**Published:** May 12, 2021
+
+For the last six months [me](https://github.com/epoberezkin) and my son [Efim](https://github.com/efim-poberezkin) have been working to bring you a working prototype of SimpleX Chat. We're excited to announce SimpleX Chat terminal client is now available [here](https://github.com/simplex-chat/simplex-chat) on Linux, Windows and Mac (you can either build from source or download the binary for Linux, Windows or Mac from the latest release).
+
+We’ve been using the terminal client between us and a few other people for a couple of months now, eating our own “dog food”, and have developed up to version 0.3.1, with most of the messaging protocol features we originally planned
+
+### Features
+
+- End-to-end encryption with protection from man in the middle attack. The connection invitation must be passed out-of-band (see [how to use SimpleX Chat](https://github.com/simplex-chat/simplex-chat#how-to-use-simplex-chat) in the repo).
+- No global identity or any usernames visible to the server(s), ensuring full privacy of your contacts and conversations.
+- Message signing and verification with automatically generated RSA keys, with keys being unique per each connection.
+- Authorization of each command/message by the servers with automatically generated RSA key pairs, also unique per connection.
+- Message integrity validation (via passing the digests of the previous messages).
+- Encrypted TCP transport, independent of certificates.
+- You can deploy your own server, but you don’t have to - the demo SMP server to relay your messages is available at smp1.simplex.im:5223 (pre-configured in the client).
+
+### We need your help!
+
+We're building a new kind of chat network - the only network that lets you control your chat. We'd really appreciate your feedback, criticism and support - a star on the github repo, signing up to the mailing list or any contribution to the project will help. There is so much more to do!
