Swiss non-profit ZeroSync Association and Bitcoin infrastructure firm Blockstream say they plan to broadcast Bitcoin zero-knowledge proofs – a type of cryptography that’s become one of 2023's hottest blockchain-tech trends – from Blockstream’s satellite.
Using zk-proofs to validate the Bitcoin blockchain means nodes don’t have to download the chain’s current 500GB of data and can therefore sync in fractions of a second instead of hours or days.

We're excited to announce that today @adam3us, CEO of @Blockstream, agreed to partner with @ZeroSync_ to broadcast #Bitcoin ZK chain proofs via Blockstream Satellite!

Blockstream’s satellite network provides free global access to Bitcoin by broadcasting the blockchain to the entire planet, including areas with unreliable Internet coverage. ZeroSync expects the first experimental broadcast to take place by the end of the year.
The newly formed ZeroSync Association was launched on Tuesday and plans to help scale Bitcoin by using zero-knowledge proofs (zk-proofs), a cryptographic technique to prove the validity of information without revealing the information itself.
“The security of Bitcoin requires every participant to verify every transaction,” ZeroSync co-founder Robin Linus told CoinDesk. “That didn't scale well until now. Proof systems like STARKs have been invented. Applying them to generate a proof of Bitcoin's chain state, and broadcasting it via satellite, can bring Bitcoin to almost everyone in the world. Don't trust, verify.”

Pudgy Penguins is building a multi-vertical consumer IP platform — combining phygital products, games, NFTs and PENGU to monetize culture at scale.
What to know:
Pudgy Penguins is emerging as one of the strongest NFT-native brands of this cycle, shifting from speculative “digital luxury goods” into a multi-vertical consumer IP platform. Its strategy is to acquire users through mainstream channels first; toys, retail partnerships and viral media, then onboard them into Web3 through games, NFTs and the PENGU token.
The ecosystem now spans phygital products (> $13M retail sales and >1M units sold), games and experiences (Pudgy Party surpassed 500k downloads in two weeks), and a widely distributed token (airdropped to 6M+ wallets). While the market is currently pricing Pudgy at a premium relative to traditional IP peers, sustained success depends on execution across retail expansion, gaming adoption and deeper token utility.
