Logs were designed to be a form of storage that costs significantly less gas than contract storage. Logs basically[3] cost 8 gas per byte, whereas contract storage costs 20,000 gas per 32 bytes. Although logs offer gargantuan gas savings, logs are not accessible from any contracts[4].
We are calling on the Ethereum community to join us in establishing a canonical ERC20-compliant wrapped ether token (WETH) in the interest of standardization across dApps and safer smart contract coding conventions. Our colleagues at Augur, district0x, Ethfinex, Gnosis, Maker, Melon, Paradex, Radar Relay and The 0…
Files are uploaded at 3x redundancy to 30 hosts. What this means is that 30 hosts end up with fragments of your data, and out of those hosts any 10 are enough to recover the original data. The magic that makes this possible is an algorithm called Reed-Solomon codes, and it was actually invented in 1960. The result is that as long as your hosts are 90% reliable each, your data has 99.999999999999999% overall reliability. It’s a very powerful way to protect data, even when the individual hosts themselves are on home con…
