Ethereum Taps Bitcoin's UTXO for Scalability Boost
Ethereum is exploring ways to improve its blockchain scaling by incorporating ideas from Bitcoin's UTXO system, according to Vitalik Buterin. The co-founder of Ethereum praised the progress made by Bitcoin developers on UTXO research and noted that the new hybrid architecture being proposed for Ethereum would enable various activities to take place using different states depending on their needs.
The native UTXO proposal relies on EIP-8141, called Frame Transactions. This proposal is about a programmable transaction frame that includes validation, gas, and execution. Currently, Frame Transactions are considered for Hegotá but are not yet approved by Ethereum. Only the FOCIL proposal has been approved for Hegotá.
Vitalik Buterin also mentioned recursive STARKs as another solution being explored to address bandwidth consumption issues associated with the growing Ethereum network. The study assumes an optimized STARK proof of about 128 kilobytes and estimates additional consumption at around 2 megabytes per second per node.
