| Dec 15, 2017 at 18:39 | comment | added | Paul | @Alpha Satoshi Nakamoto used it to include that message, to prove that the block was mined after that date. It also provides space for an extraNonce, which is used to try more hashes when mining. I'm not sure if he envisioned more uses than that, but it has been used sense then. It must contain the block height now, which is useful for guaranteeing that no two coinbase transactions are identical (which was previously an easy way for miners to make multiple transactions with the same TXID). Knowing the pool that mined a block is certainly useful as a way to measure pool centralization. | |
| Dec 15, 2017 at 18:31 | comment | added | hardfork | thank you :) But what I still do not understand: Why is this even usefull/necessary. 100 Bytes of arbitrary data per block (more than 47 Megabytes in 500,000 blocks) sounds like a waste of storage space... | |
