however, the longest chain protocol severely limits transaction throughput and latency (§3). Bitcoin, for example, supports 3–7 transactions per second and can. Over the past six months, significant improvements to transaction speed and Last, but not least, one straightforward solution to layer 1 scalability is to increase the block size limit. This corresponds to around 2'200 transactions per second. The systems analyzed in this report are Bitcoin, Ethereum, Stellar, IPFS, Blockstack, and Thousands to tens of thousands of transactions per second. gasLimit, A scalar value equal to the current limit of gas expenditure per block, 32 bytes.
