Terabyte blocks for Bitcoin Cash
December 17, 2017
Here's a brief excerpt:
Terabyte blocks are feasible both technically and economically, they will allow over 50 transactions per human on earth per day for a cost of less than 1/10th of a cent of USD. This analysis assumes no further decrease in hardware costs, and no further software breakthrough, only assembling existing, proven technologies.
As pointed out in the original Bitcoin whitepaper, achieving very large blocks do require taking advantage of Moore's Law rather than being stuck with fixed-capacity device. A terabyte block represents a block of 1e12 bytes, which can contain about 4 billion Bitcoin transactions. Assuming a worldwide population of 10 billion humans, terabyte blocks offer about 50 transactions per human per day (57 actually, but the extra numerical precision is not significant).
50 transactions per day per human appears sufficient to cover all human-driven activities; and only a healthy machine-to-machine market would require an even greater number of transactions. Such a market remains hypothetical at present time, and goes beyond the scope of this post.
Bigger blocks is the go-to plan to make the most of the hashing power invested in the Bitcoin network. Indeed, the hashing power provides the same security no matter if 1MB blocks or 1TB blocks are used, yet in the later case, the each transaction is secured with a million times less energy per transaction.
