wDOI — the entry into a productive Bitcoin ecosystem on Ethereum
Doichain has been in production for years: 20+ live applications, pilots and projects across energy, IP protection, marketing, DeFi, sport, health and infrastructure. wDOI brings this value to Ethereum as an ERC-20 — tradable, DeFi-ready, composable.
The first reservation round has closed successfully and was oversubscribed. We expect an allocation of approximately 93% of the reserved amount per participant.
If you haven't registered yet, you can still sign up to stay informed — wDOI updates, new batches, technical developments.
A productive, Bitcoin-related network — not a speculation chain.
Doichain is a productive, Bitcoin-related blockchain network with its own coin (DOI) and tokenomics identical to Bitcoin's: 21 million cap, halving, 10-minute blocks, secured via merged mining under Bitcoin's hashrate. Over 90% of the codebase is shared with Bitcoin.
Unlike pure "coin projects", Doichain has been in real-world operation for years with concrete applications — from tamper-proof energy provenance and digitised CO₂ savings to GDPR-compliant double-opt-in documentation for email marketing.
wDOI is the wrapped variant of the DOI coin on Ethereum (ERC-20). It makes Doichain's value accessible on the world's largest liquidity market and opens the ecosystem to DeFi, smart contracts and modern web3 applications.
Reservation round closed successfully — oversubscribed
The first wDOI reservation round has ended and was oversubscribed. We expect an allocation of approximately 93% of the reserved amount per participant. Final terms and next steps will be communicated by email to all participants.
- Reservation window for the first batch is closed
- Pro-rata allocation of approx. 93% per reservation
- Detailed terms will be sent by email to all participants
- New interest: registration for updates remains open at any time
In the form, pick the topics you want to hear about (wDOI updates, new batches, technical developments).
Doichain is in real-world operation — five application fields, 20+ live applications, pilots and projects
Doichain is not a whitepaper promise. It's used today in live applications — from state-funded consortium projects to commercial platforms. The per-field status reflects the dominant maturity; the full project list with individual status is on /en/highlights.
Core infrastructure & tools
The tools used to run, secure and evolve Doichain every day.
Three pillars that set Doichain apart from typical crypto projects.
Bitcoin kinship
>90% shared codebase, merged mining under Bitcoin's hashrate, identical tokenomics. Not a speculation chain, but a mature Bitcoin sister.
Post-quantum real-world lab
Testing ML-DSA, SLH-DSA, ML-KEM under real economic conditions. A Google study (04/2026) estimates <500,000 logical qubits sufficient to break ECDSA — migration is becoming concrete. Findings flow back into the BIP process.
State-funded consortia
Completed and ongoing funding projects (BlockPro, BSFZ, ZIM 'Wahrheitsmaschine') with industrial partners. Not whitepaper marketing, but documented practice.

We're testing the migration today — not when it's too late.
→ See the three-phase planTry a PQC signature
Type a short sentence. We show how large its signature would be using classical ECDSA versus post-quantum ML-DSA. The size ratio is why the migration is anything but trivial.
Note: simplified illustration. Signatures are not actually generated here — the point is the size comparison. Real values: ECDSA ~71 B, ML-DSA-65 ~2,420 B (NIST FIPS 204).

Frequently asked questions
Reservation round closed — subscribe to updates
The first reservation round has ended and was oversubscribed — approx. 93% of the reserved amount per participant will be allocated. New reservations are not possible at the moment. You can still register to stay informed and pick the topics you want to hear about — wDOI updates, new batches, technical developments.
Registration is free and non-binding. You'll receive a double-opt-in confirmation by email. Easter egg for attentive readers: the confirmation of your email is documented on Doichain itself — right where the GDPR-compliant DOI procedure originated.
No investment advice. wDOI is not a security. Crypto assets carry the risk of loss.
