Offline transactions may not be able to access blockheads at the sign-off time. Therefore, they will not be able to verify the current block header at the sign-up time. The number of coin days for a transaction is only the number of coin days that are included between the output and the block head in the transaction.
Another way to sign transactions offline, in the web3 to other public network nodes, for example: the previous example mentioned infura, is to sign the transaction online, and then transferred to the API service, using this way to pay attention to the other party (API service) may be able to modify the content of the transaction.

As in the figure above, assuming Alice mining receives 12.5 BTC awards, then its public key (address) has 12.5 BTC unspent outputs, or UTXO, that is, these 12.5 BTCs are an unspent output, forming a complete and indivisible UTXO.
Adding an address to the address book requires both an ONT ID and a Celo Address signature.
When Soros discovered the pattern, he thought the pound would fall. Of course, the possibility of losing money was also considered, and under the exchange rate mechanism at the time, the pound would lose up to 2 per cent if it did not raise interest rates. And as long as the pound depreciates, it's not just 2%, it's probably 20%.
Thrill-seeking people can now fall from the 115-meter-high Eiffel Tower's second-floor rope to the ground. The 800-meter-long rope will remain open until June 2.
After you fix the pending background, turn off the developer option to return to the app, and then turn on the invalid bug again.
