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 P2P connections are randomly choosen 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".
