If quantum-safe Bitcoin costs $75β$200 per transaction, it breaks Bitcoinβs value proposition.
Tidecoin doesnβt need that tradeoff.

Quantum-Safe Bitcoin Transactions Without Softforks
github.com/avihu28/Quantum-Sβ¦
π₯ B β @Algorand, @NEARProtocol, @NervosNetwork & @cellframenet
Algorand: optional Falcon-1024 accounts.
NEAR: ML-DSA-65 keys; validator signing remains classical.
CKB: optional SPHINCS+ locks.
Cellframe: Dilithium, but full-stack PQ coverage remains unclear.
The second release candidate for Tidecoin v1.0.0rc2, available for testing.
Improves PSBT signing, external-signer checks, wallet fee display and transaction analysis, witness-v1 and relay updates.
AuxPoW remains disabled; activation settings are unchanged.

1|7 As a quantum project, you're either building in one of these categories:
β’ quantum chain (L1/L2)
β’ privacy going post-quantum
β’ quantum as plug-in
β’ wallet/ security infra
β’ quantum computing
Or you're just simply quantum branded.
I've curated the top quantum coins that are worth watching this cycleπ
Quantum Tier List (2026)
Everyone says their chain is quantum ready but only a few can prove it.
π I ranked 34 "quantum" projects including the 28 on @Mars_DeFi's list based on
β’ quantum safety
β’ upgradability
β’ testnet/mainnet
β’ age + size
β’ privacy feature
S
.@QRLedger - every wallet has used XMSS feature, a hash-based signature quantum computers can't crack, it has been live since 2018, with multiple audits.
A
.@QuantusNetwork - uses quantum-safe ML-DSA signatures by default, but mainnet only launched this September.
.Abelian - quantum-safe lattice signatures since 2022, but its own custom design haa no public crypto audit.
.@tidecoin - uses Falcon, a quantum-safe signature, on every transaction since 2020, but it's a tiny network.
.@cellframenet wallets use Dilithium, a quantum-safe signature, by default, but adoption is small.
.@QoreChain - every transaction needs a quantum-safe ML-DSA signature, but mainnet only went live in June this year.
.@NeptunePrivacy - spending uses hash-based proofs, but it's a young chain.
.@NEARProtocol - quantum-safe ML-DSA keys are live since Jul 2026, and you can switch your account to them anytime.
.@Algorand - quantum-safe Falcon accounts are live since Aug 2026, and you can move an existing wallet over.
B
.@Starknet - its proofs are quantum-safe, but your wallet keys aren't yet, and the safe wallet is just a demo.
.@solana - an outside team built a quantum-safe vault you can opt into, the chain itself isn't quantum safe.
.@NervosNetwork - an optional quantum-safe lock exists, but you have to move funds into it.
.@trondao - quantum-safe Falcon and ML-DSA keys are being tested on its testnet.
.@tezos - testing quantum-safe ML-DSA accounts on a special testnet.
.@QANplatform - is integrating quantum-safe Dilithium signatures, but still on testnet only.
.@quipnetwork - building earky stage quantum-safe accounts for coins on other chains, still on testnet.
.@Aptos - its quantum-safe SLH-DSA accounts are coded but still waiting for a governance vote to switch it on.
.@SuiNetwork - made its first quantum-safe transaction on a dev network this month, and mainnet is targeted for 2027.
.@Tensorcash - you can create quantum-safe ML-DSA addresses, but it's a small, new network.
.Bitcoin BIP-360, a proposal for quantum-safe addresses, is still a draft
C
.@ethereum - still researching quantum-safe upgrades, most likely years away.
.@zksync - its proofs are quantum-safe, but user accounts aren't.
.@Zcash - plans for quantum-safe signatures, but nothing shipped yet.
.Qoneqt - claims a quantum-safe vault, but can't verify anything yet.
.@injective - said last week it started building toward a quantum future, but no details yet.
.@monad - quantum-safe keys are still on their roadmap.
.@aztecnetwork no quantum plan or anything substantial published yet but Mars included it in his list
.@mindnetwork_xyz - focuses on encryption, not quantum-safe signatures but seems they frame that as quantum
.@NexusMutual - security-focused imo, no quantum plan
.@Qubic - quantum-themed only, maybe to join the hype, but little real quantum-safe tech.
.@GeeqOfficial - only security claims, no quantum details
.AME Chain - claims to be quantum-secure, little public proof
.QuStream - quantum claims, little public detail
Bottom line:
Most of crypto still runs on keys a quantum computer could break. Only one project here clears every bar today and that's @QRLedger.
But there's room for growth and tech like this would take years to perfectπ
