“Things have to change in order that they remain the same”. We’re just changing we owns the keys… sad
. @PersonalAr es el peor servicio de internet de la historia. Odio me dan. No anda jamas, no son capaces de dar soporte tecnico. Me voy a terminar descubriendo de todo (celular, flow, internet) con tal de no tener que lidiar más con ellos!!

BIG news for @selfxyz x @Google, HERE is what investors* are missing:
1)Credible Neutrality - @Google, @Meta, @X, etc. (world's largest networks) are never going to work with @worldnetwork/@OpenAI /@sama, because they’re direct competitors (with de-platform risk), needs to be a credible neutral third party like @selfxyz.
2)Biometric ID, NOT Eyeballs - @selfxyz taps on the network of existing government-issued IDs without divulging any personally identifable information.
Scanning people’s eyeballs is creepy, do you really think governments around the world are going to be cool with a private company taking scans of their citizens eyeballs at scale?
3)Humanness, NOT Aliveness - Self obtains relevant meta-data (gender, age, country, etc.) using Zero-Knowledge Proofs, enabling uses cases like ensuring stablecoin payment recipients aren’t from OFAC sanctioned countries without divulging personally identifiable information, that are not possible with just scanning eyeballs.
*@VerdaVentures MiniPay Fund is an investor in @selfxyz and represents our bet on the future of identity <> stablecoin payments in a post-AI world.

🗺️ @cLabs just published their updated roadmap, outlining their plans to continue driving Celo's evolution as a frontier chain scaling @Ethereum for global impact 🌐
🧵 Check out @mcortesi5's Celo Community Forum post & keep reading this thread for a recap! ↓
What's next for @Celo as an Ethereum L2?
The cLabs team is excited to share what’s ahead, including the Isthmus hardfork, EigenDA v2, Succinct, Espresso, and a potential new testnet.

10 things I "hate" about @Celo:
1. I hate that Celo is moving from being an L1 to an OP-Stack @ethereum L2 this month… because now it’s going to be even faster, and I’ll have no excuse for slow transactions.
2. I hate that Celo focuses on real-world use cases instead of speculation… because it means people are actually using crypto for payments, commerce, and lending instead of just gambling.
3. I hate that @Minipay and @Valora have millions of normie users… because now my Web3 friends have to admit that self-custody can be easy.
4. I hate that Celo’s L2 upgrade will have 1s block times and 50M gas/s… because waiting around for transactions to settle is such a fun pastime.
5. I hate that I can pay for gas with stablecoins and use @selfxyz's SelfConnect for phone number-based addresses… because I was really starting to enjoy copy-pasting long hex strings.
6. I hate that Celo has major partners like @Opera, @Kickstarter, @DeutscheTelekom, and @Telefonica… because it’s hard to pretend crypto is just a toy when these companies are all in.
7. I hate that Celo is the chain for stablecoins… because now there are so many choices that I don’t even know which one to use for gas. Just look at @tether USDT, @circle’s USDC, @MentoLabs (cUSD, cEUR, cREAL, cPHP, cKES, cCOP), @AngleProtocol, @BRLAdigital, and more.
8. I hate that the dev tooling is already solid and supports blue-chip protocols… because now I have no excuse not to start building immediately. Just ask @Uniswap, @CurveFinance, @Bancor, @rarible, @etherscan, @blockscoutcom, @thirdweb, @chainlink, @redstone_defi, @hyperlane_xyz, @LayerZero_Core, @wormholecrypto, @axelarcore, @squidrouter, @Anchorage, @BitGo, and @CoinbaseInsto.
9. I hate that Celo has tons of on/off ramp options and exchange listings… because onboarding users is way too easy. Shoutout to @RampNetwork, @moonpay, @Transak, @fonbnk1, @cashramp, @usepartna, @bitmamaexchange, and @yellowcard_app.
10. And most of all, I hate that every transaction on Celo programmatically offsets CO2 emissions through the Ultragreen Money program… because now I can’t even feel guilty about using blockchain.
Come build with us. I dare you.

@Celo L2 and @base both use @Optimism, why not support @Celo?
The optics of the situation are that @coinbase is using monopolistic centralized power to king make @base in a supposedly decentralized world.
@coinbase is an outstanding company with a mission "to increase economic freedom in the world," so I hope that there's a rational that is different from the optics.
