Bitcoin Core v26.0 Upgrade Live with Experimental Support for v2 Transport Protocol

Bitcoin$42,260 -0.64% Core, the primary open-source software that powers the blockchain of the world's leading cryptocurrency, has rolled out its latest upgrade, v26.0. This upgrade introduces experimental support for the v2 transport protocol as outlined in Bitcoin Improvement Proposal 324 (BIP324).

Enhanced Security Through BIP324

BIP324 aims to augment the security of Bitcoin Core by enabling encryption of communication between nodes. This is set to reduce the chances of attacks through transaction tampering. The new peer-to-peer (P2P) protocol version (v2) elevates the costs of such attacks, primarily via unauthenticated, opportunistic transport encryption.

One significant benefit of this upgrade is that, even when unauthenticated and used only when both endpoints support v2, encryption obstructs eavesdropping, compelling the attacker to become active. However, the existing V1 transport protocol continues to be supported, with users needing to enable V2 to begin using it.

Introduction of BIP324

Core contributor Dhruvkaran Mehta, who shifted his focus to a Bitcoin-related startup idea in April this year, introduced BIP324. The v26.0 upgrade also encompasses various modifications to remote call procedures (RPCs), including those pertinent to wallets, and alterations to Bitcoin's graphical user interface (GUI).
