# Hush Overview

## Mining Algorithm

Equihash (200,9) (ASIC)

## Block time

75 seconds

## Block size

4MB

## P2P

TLS1.3 via WolfSSL is enforced for all network connections as of v3.6.1 .
Many ciphersuites are technically supported by TLS1.3 but many of them
are ancient, proved to be less secure than intended or likely backdoored.
Hush only uses what are widely considered to be the most secure and [best ciphersuites](https://ciphersuite.info/cs/).

New Hush P2P connections randomly choose between these two ciphersuites each
time a new connection to a peer is created:

  * `TLS_AES_256_GCM_SHA384`
  * `TLS_CHACHA20_POLY1305_SHA256`

## RPC

Inherited many RPC's from Bitcoin and Zcash with many new ones

## Consensus

Hush is a mandatory privacy blockchain as of Block 340000 (Nov 2020),
which means you can only send to a shielded address, never to a transparent
address. This is enforced via consensus rules and sometimes called "z2z".
