A blоckchаin uses а Merkle Tree tо аuthenticate a transactiоn within a block. Each transaction TiT_i in a block is hashed, and these hashes are used to create the Merkle tree structure. For simplicity, assume the block has four transactions, and the Merkle tree is built as follows: Transactions: T1,T2,T3,T4T_1, T_2, T_3, T_4 Hashes of individual transactions: H(T1),H(T2),H(T3),H(T4)H(T_1), H(T_2), H(T_3), H(T_4) The Merkle tree is constructed by hashing pairs of transaction hashes. First, the leaf nodes are: H1=H(H(T1)∥H(T2)),H2=H(H(T3)∥H(T4))H_1 = H(H(T_1) | H(T_2)), quad H_2 = H(H(T_3) | H(T_4))Next, these two hashes are hashed together to create the Merkle Root: Hroot=H(H1∥H2)H_{text{root}} = H(H_1 | H_2)Where ∥| denotes concatenation of the hashes. Bob wants to verify that transaction T2T_2 is part of the block. He receives the following data from Alice: The Merkle Root HrootH_{text{root}} The hash of T2T_2T2 (which is H(T2)H(T_2)) The sibling hashes H1H_1 and H2H_2 (used to reconstruct the path from T2T_2 to the Merkle Root) What mathematical steps does Bob need to take to verify the inclusion of T2T_2?
