An open source project aiming to support Bitcoin’s on-chain scaling, CashDB just released its alpha version.
The creator, Lokad’s founder, Joannes Vermorel said in the announcement that CashDB is a blockchain-centric key-value store specifically tailored for the set of unspent transaction output or the UTXO set of Bitcoin.
CashDB is said to be able to process of almost 20,000 transactions per second using a single Intel Optane 900P card, which means that a 1GB BTC block can be processed in around 3 minutes and half.
Thus, Vermorel believes that CashDB is already “scalable enough” to process gigabyte blocks at peak network capacity. That said, since its throughput is too low, it is not yet capable to support sustained gigabyte blocks.
Vermorel is still convinced, though, that CashDB is enough “for now”, considering Visa’s average volume is still at around 2,000 transactions per second.
Closing the announcement, he said CashDB is “a small step toward decoupling the software parts that make Bitcoin” as it is actually intended as a support component for full BTC implementations, such as Bitcoin ABC or ElectrumX.
