About BRIAN Pool
Run by an engineer working in medical technology, BRIAN is a single-pool operation kept online for family, friends and the wider Cardano community — with no expectation of anything in return beyond a stable, reliable node on the network.
Non-custodial
Your ADA always stays in your own wallet. Delegating never transfers ownership or moves your funds.
Long-term, low margin
A 1.00% margin and the standard 170 ₳ fixed cost per epoch — priced for sustainability, not short-term yield.
Independent governance
Also active as a registered DRep, making on-chain governance decisions independently of the pool's own interests.

Pool Info
Infrastructure and on-chain performance for pool BRIAN.
Infrastructure
Three relay nodes run on Contabo VPS instances in France, the UK and the US. The block producer runs on a dedicated, high-performance server, kept isolated from the public relays for added security.

Operations
The pool is monitored daily and node updates are applied promptly. BRIAN also runs a Mithril Signer, contributing cryptographic signatures to Cardano's fast-bootstrap snapshot network — letting new nodes verify and sync from a certified chain snapshot instead of replaying the full history from genesis.

How to Delegate
Delegating takes a few minutes, costs a small one-time network fee (~0.17 ₳), and can be changed or undone at any time.
Open your wallet
Use a Cardano light wallet such as Eternl or Daedalus and go to the "Staking" or "Delegation" section.
Search for BRIAN
Search by ticker BRIAN or paste the pool ID above directly into the pool search field.
Confirm delegation
Review the pool details, confirm the transaction, and sign it. Your ADA stays in your wallet the whole time.
Earn rewards
Rewards start arriving automatically roughly 15–20 days after delegation, every epoch, directly to your wallet.
Cardano, Technically
A short primer on the protocol design that makes staking on Cardano work the way it does.
Ouroboros Praos
Peer-reviewed, provably secure proof-of-stake consensus. Slot leaders are chosen pseudo-randomly, weighted by stake — no mining, no energy race, with security proven mathematically rather than assumed.
Extended UTXO (eUTxO)
Builds on Bitcoin's UTXO model and adds scripting on top. Every transaction's validity can be checked locally and deterministically before it's ever submitted — no global state required.
Plutus & Haskell
Smart contracts run in Plutus, built on Haskell. A functional, strongly-typed foundation was chosen deliberately, so core protocol components can be formally verified rather than just tested.
Epochs & slots
Time is split into 5-day epochs made up of 1-second slots. Stake distribution is snapshotted once per epoch — the reason staking rewards arrive with a multi-epoch delay, not instantly.
Voltaire governance
Under CIP-1694, on-chain governance power over protocol parameters and treasury spending is split between ADA holders, DReps, SPOs and a Constitutional Committee — no single party decides alone.
Energy efficiency
Proof-of-stake replaces energy-intensive mining with cryptographic, stake-weighted selection — using orders of magnitude less energy per transaction than proof-of-work chains like Bitcoin.
Governance & DRep
Beyond running the pool, BRIAN also participates in Cardano's on-chain governance (Voltaire / CIP-1694) as a registered Delegated Representative (DRep).
Governance decisions are researched and made independently, treated as separate from the pool's own interests. ADA holders are encouraged to register as their own DRep, or delegate voting power to a representative whose reasoning they trust — participation matters more than any single outcome.

Frequently Asked Questions
Is my ADA locked up when I delegate?
No. Delegated ADA remains liquid and spendable at any time. Delegation only assigns your stake's weight to a pool — it does not lock or transfer your funds.
Is there a minimum amount to delegate?
No minimum amount is required. You only need enough ADA to cover the small one-time delegation transaction fee (about 0.17 ₳) plus the wallet's minimum UTXO requirement.
Can I switch pools later?
Yes, you can re-delegate to a different pool at any time by submitting a new delegation transaction from your wallet.
How often are rewards paid out?
Rewards are calculated and distributed automatically every epoch (5 days) once your delegation becomes active, typically 15–20 days after you first delegate.
Why choose a small pool like BRIAN over a large one?
Cardano's protocol rewards decentralization: delegating to smaller, non-saturated pools helps keep the network healthy and can offer comparable long-term rewards to large pools.
