Why Platform Portability is a Myth Without DIDs

Your on-chain history is siloed. A whale on Ethereum is a ghost on Solana. This breaks credit systems, DAO governance, and personalized dApp experiences.

• Reputation is non-portable: Aave credit delegation or Uniswap fee tiers don't follow you.
• Sybil resistance fails: You must rebuild proof-of-personhood on each new chain.
• User experience is fractured: No unified profile for Farcaster, Galxe, or gaming achievements.

Bridges like LayerZero and Axelar move tokens, not positions. Your Curve LP stake or Aave collateral is stranded, forcing costly exits and re-entries.

• Capital inefficiency: $10B+ TVL is locked in single-chain deployments.
• Slippage & fees compound: Bridging then swapping via UniswapX or 1inch adds layers of cost.
• Yield is lost: You forfeit rewards and governance power when you move.

A Decentralized Identifier (DID) anchored to a zk-proof or off-chain signature becomes your portable root of trust. It enables verifiable claims about your assets, history, and credentials across any chain.

• Unified reputation: Prove your Ethereum NFT holdings to access a Solana lending pool.
• Intent-based bridging: Systems like Across and CowSwap can use DIDs for gasless, cross-chain settlements.
• True composability: DApps on Arbitrum, Base, and Avalanche read from a single, user-owned identity graph.

Every new app forces users to start from zero, fracturing capital and reputation. This kills network effects and inflates CAC.

• Problem: A user's $10K Uniswap LP position and 5-star Lens reputation are useless on a new DeFi platform.
• Solution: Portable DIDs enable cross-platform credit scoring and collateralized social graphs, turning user history into a composable asset class.

Wallet creation and seed phrase management block the next billion users. The "connect wallet" paradigm is a growth ceiling.

• Problem: Users face ~5-minute setup per app and constant security anxiety, leading to >90% drop-off.
• Solution: DIDs with embedded MPC or passkeys enable one-click, seedless onboarding. Think "Sign in with Google" but self-custodied, unlocking non-crypto-native audiences.

Airdrop farming and governance attacks are multi-billion-dollar leaks. Proof-of-personhood without KYC is crypto's unsolved problem.

• Problem: Projects like Ethereum Name Service and Optimism lose >30% of token supply to sybils, distorting incentives.
• Solution: DIDs anchored in persistent, non-transferable identifiers enable programmable sybil resistance. This allows for fair launches, accurate DAO voting, and targeted incentives.

Monolithic apps are dead. The future is cross-chain, cross-VM, cross-rollup. Identity must be the unifying layer.

• Problem: A user's Solana NFT, Arbitrum DeFi position, and Base social profile exist in separate universes.
• Solution: Chain-agnostic DIDs (e.g., ENS, SPACE ID) become the portable root for all assets and activity. This enables intent-based architectures like UniswapX and cross-chain aggregators like Across to work seamlessly.

Platforms like Facebook monetize your data. Web3 inverts this: users own and monetize their own graph.

• Problem: Your attention and social capital are extracted by centralized platforms, creating $100B+ market cap companies from your data.
• Solution: DIDs with verifiable credentials let users lease their reputation to protocols, participate in data markets, and receive fees for their attention—turning users into stakeholders.

Global compliance (FATF Travel Rule, MiCA) is coming. Pseudonymous wallets won't cut it for institutional adoption.

• Problem: Protocols face existential risk by servicing anonymous wallets, blocking trillions in institutional capital.
• Solution: Privacy-preserving DIDs with selective disclosure (e.g., zk-proofs of jurisdiction) enable compliance without doxxing. This unlocks institutional DeFi and RWAs at scale.
