Blockchain is the underlying technology behind cryptocurrencies bringing together Merkle trees, Hashing & Distributed Architecture. Christopher Ellis explains.
Note1 – At 6:46 when Chris is drawing the Merkle Tree, C would actually be duplicated and hashed with itself not with B. So you would get H(C – C) instead of H(B – C).
Note2 – At minute 17, Christopher mentioned the mining reward halving at 21,000 bitcoins but meant 210,000 blocks.
