Table 4 Structure of the proposed block root-of-trust \(J_i\)
Offset (bits) | Field | Size (bits) | Description |
|---|---|---|---|
0 | \(T_i\) | 256 | Root hash of the Merkle Tree for the new block \(B_i\) |
Built using new user-IDs | |||
256 | n,m | 24 | n: total number of users, m: how many present |
280 | Flags \(\phi\) | 8 | Bits 0,1: bitmap type (plain, compressed, list, empty) |
Bit 2: (0: \(w=4\), 1: \(w=8\)) | |||
Bits 3–7: pre-randomisation parameter (see next section) | |||
288 | Bitmap M | \(L\le 1024\) | Processed bitmap content |
\(L+288\) | Redundancy | 32 | All zeros, for PLS validation |
