Vitalik says Ethereum nodes can now sync in half a day with disk use below 0.5TB

Ethereum co-founder Vitalik Buterin said in a post on X that Ethereum nodes can now complete synchronization in half a day, and that disk usage can be kept below 0.5TB under a more aggressive configuration. He said the improvement in node usability has come from EIP-4444 and continued optimization of Snap Sync by client teams, with the upcoming Glamsterdam upgrade expected to improve sync efficiency further. Buterin also pointed to practical limits around using local infrastructure. Users can direct a wallet RPC to a local node, he said, but only if the node’s RPC functions are configured properly. Even then, some browser-based dApps may not work well with a local RPC, while other applications hardcode RPC connections to their own servers. On his own workflow, Buterin said he has become more inclined to avoid browser dApps and use command-line tools instead. He added that he has already updated ENS records through a Python script connected to a local node. He also said kohaku-cli is set to integrate privacy protocols further, and that early development work is already underway.

Libbitcoin Server can complete Bitcoin initial block download in 55 minutes, developer says

Libbitcoin developer @evoskuil said the latest version of Libbitcoin Server can complete a Bitcoin full node’s initial block download and full validation in 55 minutes. He attributed the speedup to a new GPU-based signature verification system that runs in parallel with standard script validation instead of being handled as a separate step. According to his description, the software does not stop to verify each ECDSA and Schnorr signature one by one. It captures signature checks, batches them, and sends them to the GPU while the rest of the validation process continues. @evoskuil said the approach can capture about 99.5% of signatures without blocking validation, removing the need for a second verification pass. If a batch signature check fails, the software traces the failure back to the relevant block and marks that block as invalid. He added that the design can batch nearly any number of signatures, allowing the GPU to stay ahead of the rest of the validation pipeline and sharply reduce full-node sync time.

Bitcoin Core v32 is set to speed up node sync by 30%-40%

Bitcoin Core’s upcoming v32 release is expected to improve blockchain synchronization speeds by 30%-40%, according to Bitcoin developer Jameson Lopp. The gain comes from better parallel processing and is aimed mainly at the Initial Block Download, or IBD, the step new nodes go through when joining the network for the first time. A faster IBD process would shorten the time required for a fresh node to become operational. Bitcoin Core is the reference implementation for the Bitcoin network and is maintained by a global open-source developer community. Because it sits at the base of Bitcoin’s infrastructure, performance improvements in the software matter for lowering the barrier to running a node and supporting decentralization across the network. Lopp said the code changes are already in the late stages of development. A specific release date for v32 has not been announced.
