Interface BlockInfoAnswer

What a backend says about a block when asked for it directly.

Only tx_count reaches the bundle. The other three are here because an esplora /block/<hash> response carries them anyway, so checking them costs no request and catches a backend contradicting itself for free.

interface BlockInfoAnswer {
    height?: number;
    id?: string;
    merkle_root?: string;
    tx_count: number;
}
