Think DAOs mean decentralization? Think again. 80% of governance votes are controlled by just 3 wallets! Let's debunk this myth. #BlockchainReality

This is a technical whitepaper, not a launch announcement. We want security researchers, ZK engineers, and bridge builders to tear this apart. Read it: https://t.co/zvtm2qJyPW DMs open for technical discussion 🔓

Trade-offs we chose: ✅ Cryptographic soundness > signature trust ✅ ~20-25s latency (competitive with intent bridges) ❌ ~$4-6 EVM withdrawal cost ❌ Sequential IMT updates limit throughput Not "trustless." Trust-MINIMIZED with explicit limitations.

Architecture: Solana → Compressed state (Light Protocol, 95% cost reduction) Relayer → Groth16 proof generation (off-chain) EVM → On-chain verification (~200k gas) Key: Poseidon nullifiers prevent replay, IMTs prove non-membership.

Bridges lose billions because they trust multisig committees. Meridian Link replaces signatures with ZK proofs. A relayer can censor your transaction, but they can't steal your funds. Here's how we built it 🧵

This is a research contribution, not marketing. We want: → Cryptographers to review the threat model → ZK engineers to challenge our circuit design → Bridge builders to discuss trade-offs Read the whitepaper: https://t.co/zvtm2qJyPW Open questions & collaboration welcome.

Technical highlights: • Poseidon hashing for nullifiers (~300 constraints vs 25k for SHA-256) • Light Protocol compressed accounts: 15k lamports vs 1.6M for PDAs • Indexed Merkle Trees for non-membership proofs • BN254 curve for EVM compatibility Full cryptographic specs in

Honest trade-offs: ✅ Groth16 provides ~100-bit security (not "trustless") ✅ Relayer compromise = censorship, NOT theft ✅ 95%+ cost reduction via state compression ❌ Throughput: ~12-20 tx/min (sequential IMT updates) ❌ EVM withdrawal: ~$4-6 at 30 gwei We chose soundness

Here's how Meridian Link works: Three layers: • Solana (compressed state via Light Protocol) • Off-chain relayer (Groth16 proof generation) • EVM (on-chain verification) Relayer can't forge proofs. Only censor.

The insight: Replace signature aggregation with zero-knowledge proofs. Instead of "13 people attested to this transfer," we prove: ✓ Deposit exists in Solana state tree (cryptographically) ✓ Nullifier prevents replay ✓ No trusted intermediaries needed Math > multisig.

Cross-chain bridges have lost $2.5B+ between 2022-2023. The core problem: trust assumptions. Most bridges rely on multisig committees (Wormhole: 13/19 guardians). Compromise 7 signers → arbitrary message forgery. We built something different. 🧵

Secure proxy voting with on-chain checks. Start by implementing a verified delegation registry today. What’s your biggest challenge?

Real-world risk: attackers delegating votes without consent can tilt governance.

Fix: use an on-chain delegation registry linked to holder signatures and revocation checks.

If on-chain checks are missing, any signature could authorize a vote.

Signatures alone don't prove consent. Without live verification, delegated votes can be forged.

Law says proxy voting is allowed. On-chain logic often lacks proof of consent. This thread reveals why the gap matters and how to fix it.

The algorithm is broken. The shipping is not. The builders are busy. It’s the first weekly newsletter of the year, and we’re starting 2026 the only way Solana knows how: 🚢🚢🚢 📰 Headline News - @MorganStanley filed an S-1 with the SEC to launch Solana ETF - @wyostable

Design isn't just an aesthetic choice—it's foundational to real decentralization. Architect your DAO to avoid whale control. #TrueDecentralization

Want to know how decentralized your DAO truly is? Start by measuring the Nakamoto Coefficient. It's like a decentralization audit. #BlockchainMetrics

Whale voting isn't just a buzzword—it's a real threat to DAO governance. Why let a few control the many? #DecentralizationTheater
