The latest upgrade to Bitcoin Core, the primary open-source software for connecting the blockchain behind the world's largest cryptocurrency, is now live.

The v26.0 upgrade contains experimental support for the "v2" transport protocol as defined by Bitcoin Improvement Proposal 324 (BIP324), which seeks to encrypt communication between nodes reducing the risks of attacks via tampering with transactions.

"This proposal for a new P2P protocol version (v2) aims to improve upon this by raising the costs for performing these attacks substantially, primarily through the use of unauthenticated, opportunistic transport encryption," according to the proposal. A key benefit is that "encryption, even when it is unauthenticated and only used when both endpoints support v2, impedes eavesdropping by forcing the attacker to become active."

The existing V1 transport protocol remains supported. Users must enable V2 in order to start using it.

BIP324 was introduced by prominent Core contributor Dhruvkaran Mehta, who stepped away from the project in April this year to focus on a Bitcoin-related startup idea.

The upgrade also includes various changes to remote call procedures (RPCs), including those related to wallets and changes to Bitcoin's graphical user interface (GUI).

Pudgy Penguins: A New Blueprint for Tokenized Culture

Pudgy Title Image

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.

Bitcoin's Quantum threat is ‘real but distant,’ says Wall Street analyst as doomsday debate rages on

Wall Street broker Benchmark argued the crypto network has ample time to evolve as quantum risks shift from theory to risk management.

What to know:

  • Broker Benchmark said Bitcoin’s main vulnerability lies in exposed public keys, not the protocol itself.
  • Coinbase’s new Quantum Advisory Council marks a shift from theoretical concern to institutional response.
  • Bitcoin’s architecture is conservative but adaptable, according to Benchmark analyst Mark Palmer, with a long runway for upgrades.
