WebDirected Acyclic Graph (DAG) coins. IOTA’s Tangle, Byteball, and Raiblocks are examples. They’re gaining a lot of traction as they seem to be a really awesome alternative to the blockchain. RaiBlocks uses a block-lattice structure. Each account has its own blockchain (account-chain), equivalent to the account's transaction/balance history. WebThe basic block of each leader contains all the instructions from itself until just before the next leader. Thus, the basic block of 1 is just 1, for leader 2 the block is just 2. Leader 3, however, has a basic block consisting of instructions 3 through 9, inclusive.

DAG: Total nodes are 8 but nodes b + b + c + d and b + c + d are repeated so only one time will be counted so total nodes are 8 - 2 = 6. Each repeated nodes has two edges so total edges will be 10 - 4 = 6. Hence 6 and 6 is the correct answer. Download Solution PDF.
