How Founders Are Using Blockchain for Payments, Identity & More

In the rapidly evolving world of Web3, founders are pioneering innovative applications of blockchain technology far beyond its cryptocurrency origins. From streamlining cross‑border payments to bolstering digital identity, today’s startups are building the infrastructure for a more secure, transparent, and inclusive internet. This blog explores three core pillars—payments, identity, and “everything else”—and offers practical insights for founders looking to leverage blockchain in their ventures.

1. Decentralized Payments: Faster, Cheaper, Borderless

Cross‑Border Remittances

• Instant settlement: By cutting out traditional intermediaries (correspondent banks, card networks), blockchain rails can settle transactions in seconds rather than days.

• Lower fees: Startups like Ripple (using XRP) and Stellar Lumens (XLM) have demonstrated sub‑1% transfer costs, a game‑changer for migrant workers and SMEs.

• 24/7 network: No weekends or holidays—payments flow any time, any place.

Merchant Adoption

• On‑ramp/out‑ramp solutions: Companies such as BitPay and Coinbase Commerce provide turnkey APIs and point‑of‑sale plugins, letting merchants accept crypto without worrying about volatility.

• Programmable payments: Smart contracts enable conditional payouts—e.g., releasing funds only when shipment is confirmed—which reduces disputes and automates escrow.

2. Self‑Sovereign Identity: Putting Users in Control

Verifiable Credentials

• Portable digital IDs: Protocols like Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) allow individuals to own and share only the data they choose, without central repositories.

• Phishing-resistant logins: Blockchain‑backed authentication (e.g., via MetaMask or self‑custodial wallets) removes passwords entirely, dramatically reducing account‑takeover risk.

Compliance & KYC

• Selective disclosure: Instead of handing over full identity documents, users can cryptographically prove specific attributes—like being over 18 or residing in a certain country—without exposing sensitive details.

• Shared attestations: Banks, universities, and government agencies can issue verifiable attestations on‑chain. Startups like Civic and Evernym are building networks of trusted issuers.

3. Beyond Payments & Identity: Supply Chains, Governance & More

Transparent Supply Chains

• End‑to‑end provenance: Blockchain immutability ensures every product—from coffee beans to pharmaceuticals—carries an unbroken record of origin, handling, and certification. Companies like Everledger (diamonds) and IBM’s Food Trust (produce) showcase real‑world deployments.

Decentralized Governance & Tokenization

• DAO frameworks: Decentralized Autonomous Organizations (DAOs) empower communities to vote on budgets, protocols, and strategic decisions without a central board. Platforms like Aragon and Snapshot simplify proposal creation and weighted voting.

• Asset tokenization: Real‑world assets—real estate, art, carbon credits—can be fractionalized into tokens, unlocking liquidity and broadening investor access. Projects like RealT and tZERO lead the charge here.

4. Strategic Tips for Founders

1. Choose the Right Layer

   • Performance vs. decentralization: High‑throughput chains (e.g., Solana, Polygon) excel in micropayments, while highly decentralized networks (e.g., Ethereum, Bitcoin) offer stronger security guarantees.

2. Prioritize UX and Abstraction

   • Hide complexity: Users shouldn’t need to understand private keys or gas fees. Consider custodial options, meta‑transactions, or gas‑station relayers to streamline onboarding.

3. Build Interoperably

   • Cross‑chain bridges: Opt for standards (ERC‑20, ERC‑721, DID, VC) and leverage protocols like Polkadot or Cosmos if multi‑chain composability matters.

4. Plan for Regulation

   • Engage early: Whether in payments (money‑transmitter laws), identity (data privacy), or tokenization (securities laws), consult legal counsel proactively to avoid costly pivots later.

Blockchain’s transformative potential extends well beyond speculative trading. By rethinking how value, identity, and governance are exchanged, founders are architecting more equitable, efficient, and trustworthy systems. Whether you’re launching a cross‑border remittance app, a self‑sovereign identity platform, or a supply‑chain provenance network, these guiding principles can help you navigate technical trade‑offs and regulatory landscapes.
