Blockchain Upgrades Accelerate as Bitcoin Core Fixes Privacy Flaw

June has been a busy month for blockchain technology updates. Developers have been patching privacy holes, rescheduling major upgrades, and pushing quantum-resistance proposals.

Bitcoin Core's version 31.1 fixes a privacy vulnerability in the -privatebroadcast feature of version 31.0 that could expose a transaction initiator's IP address.

Ethereum's Glamsterdam upgrade has been postponed to the second half of the year, and EIP-8182, a native private transfer proposal, is set for inclusion in the Hegotá hard fork.

Consensys CEO Joseph Lubin predicts that Ethereum could become a fully zero-knowledge-proof-based protocol within 3 to 5 years.
