has a home.

IN ONE MINUTE

First, plainly: what it is — and what it isn’t.

What is Beyul?

A settlement-network design that puts privacy and accountability together: transactions are private by default, and when needed you disclose only specific information to specific parties.

Can I move real money today?

No. It is a research prototype — no testnet, no mainnet, unaudited, and not for real funds.

So what can I try right now?

An interactive demo, a wallet prototype on a simulated network, and a block explorer with demo data — all for research.

What it is not

Not absolute anonymity, and not a tool to evade regulation or audit. Privacy and accountability, together, is the design goal.

01WHAT IS A BEYUL

Beyul (སྦས་ཡུལ) — Tibetan: a hidden sanctuary valley.

Protected. Invisible. Open only to those permitted.

A sanctuary does not hide — it simply does not open to those it does not concern. We named this network after it: your financial life resides in the valley, sheltered by the protocol. When the gate opens, for whom, and how far — you decide.

Privacy by default. Disclosure by choice.

02THE PROBLEM

Public ledgers were never designed for privacy.

  • Salaries
  • Treasury operations
  • Donations
  • Supply chains
  • Institutional settlements

None of these should be permanent public records. On transparent ledgers, they are.

03DISCLOSURE

One transaction. Four perspectives.

Amount

2,450,000.00

Sender

Meridian Capital

Recipient

Atlas Holdings

Memo

Q2 settlement

Reconciliation

Reconciled

Validity proof

Target: on-chain validity proof

As the owner, you see everything.

Demo shows the target design. Current prototype boundary: deposit and withdrawal amounts are still public on-chain. Threat model →

04DISCLOSURE IS NOT BINARY

Between fully public and fully hidden, there is a third model.

01

Personal privacy

Your history belongs to you. No observers — including the network itself.

02

Transaction disclosure

Prove a chosen transaction to a chosen party. That one, and only that one.

03

Asset disclosure

Prove what you hold without surrendering where it came from.

05ACCOUNTABILITY

Built for accountability.

Privacy and accountability are not opposites — lose either, and the other cannot stand.

Auditing

Verification within granted scope — not an open ledger.

Verification

Every transaction provably valid, on-chain.

Institutional reporting

Produced on demand. Purpose-bound, scope-bound.

Financial integrity

The network verifies. It does not watch.

Auditability in full →

06RESEARCH BEFORE PROMISES
