Feeless Transactions — Sikka enforces exact input and output balance, so users send full value without losing part of the transfer to network fees.
No Blocks, Parallel Scaling — Transactions attach directly to the DAG instead of waiting for the next block, allowing the network to grow across multiple tips in parallel.
Post-Quantum Signatures — Transaction signing, wallet signing, and multisig witnesses use ML-DSA-87 instead of classical signature schemes.
Tor-Native Networking — Nodes run with managed Tor support, advertise onion addresses, and expose privacy-friendly peer connectivity out of the box.
Built-In Spam Resistance — Every transaction carries its own proof-of-work, and congestion raises work requirements so abusive traffic becomes more expensive to push.
Lightweight & Fast — The production Docker image is just 17 MB, making nodes fast to pull, easy to deploy, and cheap to run.
HTTP Federation — Nodes communicate and synchronize over HTTP, keeping peer connectivity simple, accessible, and easy to operate.
Built-in Wallets — Sikka includes browser-based wallet support for both standard single-key usage and native threshold multisig flows.
Docker Ready — Launch a node in seconds with a single container while keeping chain data, peers, and identity persisted across restarts.
