Israeli company StarkWare has announced a plan to invest $1 million in research and development aimed at scaling Bitcoin using zero-knowledge rollups. This demonstrates a serious commitment to the future scaling of Bitcoin.

At the core of the plan is the use of rollups, which allow transactions to be aggregated off-chain and verified on the blockchain at a fraction of the cost. A key element is the proposal to reintroduce the Bitcoin blockchain command OP_CAT, allowing developers to set conditions for future transactions, including automated payments and reversible transactions.
