Software developer Awemany has published a potential alternative approach to instant transactions on the Bitcoin Cash (BCH) network called “delta blocks” or Storm. The idea utilizes weak proof-of-work (PoW) for instant confirmations on Bitcoin Cash. The new Storm concept has piqued the interest of many BCH proponents who are eager to solve the instant or zero-confirmation transaction problem.

Awemany Publishes Storm Whitepaper, a Possible Solution to the Double-Spend Problem
Awemany has published a whitepaper, source code, and simulation for a new concept for the BCH network called Storm. The pseudonymous blockchain engineer is the same developer who found the exploit in the Bitcoin Core reference client in September 2018. Additionally, last year at the Satoshi’s Vision Conference, Awemany introduced a solution to the zero-confirmation problem by using a concept called Zero-Confirmation Forfeits. For years now, developers have been trying to create a pre-consensus system for double-spend attacks. In essence, a double-spend attack is used to redirect a payment that was sent to a merchant in order to spend the funds already used in the transaction before a blockchain confirmation. An unspent output is spent in two different transactions and a miner must choose between one of them.
One side product of the network is when miners generate blocks with reduced difficulty (weaker PoW) called “weak blocks.” The concept Awemany proposes is a scheme that merges multiple weak blocks called delta blocks that allows for “reaching consensus on transaction inclusion, to give merchants the tools needed to estimate double-spending risk.” Basically, the connected BCH blocks are used to denote valid transactions so merchants can be sure instant
