Royalty wars (2022-2024)
NFT royalties enforced only at marketplace level (not chain-level). Blur 0% royalty (2022) sparked race-to-bottom. OpenSea Operator Filter controvérsia. By 2024, royalties largely optional/marginal — many collections moved to on-chain enforcement via transfer restrictions.

Art Blocks
Erick Calderon (Snowfro) 2020. Curated platform: artists submit code; collector mints triggers seed → unique generation.
- Curated tier (highest): Fidenza (Tyler Hobbs), Ringers (Dmitri Cherniak), Chromie Squiggles (Snowfro), Sukyaba.
- Playground, Factory: less curated.
- Engine (now Art Blocks Studio): white-label platform.
Records: Ringers US$ 6.9M (Christie's 2023).
fxhash, Hic et Nunc (defunct), objkt
Tezos-based art platforms (lower fees + clean energy narrative).
5. ENS (Ethereum Name Service)

.ethnames registered as ERC-721.- Resolution: address ↔ name; metadata, content hash, social links.
- Subdomains free.

ENS virou identidade default no Ethereum. Twitter/X integration via verified badges.
6. GameFi / Play-to-Earn
Axie Infinity
Sky Mavis (Vietnam) 2018. Pokemon-like creatures, breeding, battles. AXS + SLP tokens. Ronin sidechain.
Peak 2021-2022:
- Pacific countries (Philippines) — players earning livable wages via P2E.
- Sky Mavis valuation US$ 3B.
Decline:
- SLP inflation → economy collapse.
- Ronin Bridge hack (mar/2022, US$ 625M) — Lazarus N. Korea.
- Player count dropped 90%.
- Pivot to Axie: Origins (free-to-play).
Other GameFi (mostly struggled)
- Gods Unchained: TCG, Immutable X.
- Illuvium: open-world RPG, Aurora L2.
- Stepn: move-to-earn (run + earn GST). Peak 2022, crash.
- Bigtime: ARPG.
- DeFi Kingdoms: DeFi gamified Harmony→Avalanche.
Modern (2024-2026 traction)
- Pixels (farming sim, Ronin).
- Off The Grid (Gunzilla, AAA shooter).
- Star Atlas (Solana, MMO).
- Parallel (TCG, Base).
- Telegram games: Notcoin, Hamster Kombat — massive user numbers via TON. Tap-to-earn questionable depth.
Web3 gaming critique
- "Sustainable economics" elusive.
- "Game first, crypto invisible" thesis (Pixels, Off The Grid) — better than crypto-first.
- Steam bans Web3 games; Epic allows.
- AAA blockchain games still mostly vapor (Off The Grid is exception).

13. Risks específicos
NFTs
- Royalty enforcement weak.
- IP rights: contract NFT ≠ copyright transfer (commonly misunderstood).
- Wash trading: artificial volume to game rewards (Blur era).
- Phishing: signature-based wallet drainers; "blind signing" risk.
- OFAC sanctioned wallets holding traceable.
GameFi
- Ponzi-economics: P2E rewards from new player buy-in eventually exhausts.
- Bot farming dilutes legitimate players.
- Liquidity flight quando narrative shifts.
RWA
- Custodial counterparty risk (BUIDL = BlackRock; if BlackRock fails, token worthless).
- Regulatory: securities laws apply. Most RWA tokens são permissioned (KYC).
- Off-chain enforcement dependency.
DePIN
- Hardware capex for participants.
- Token incentive sustainability post-bootstrap.
- Quality control decentralized (Helium IoT lagged).
Identity
- Privacy: World ID iris scanning controversial.
- Centralization: SBT issuer trusted.
