Qtum halvings are based on a 4-year interval of 3,942,000 blocks. Every 4 years the block reward drops by half and will drop from 1.0 QTUM to 0.5 QTUM on December 1st, 2021.

The calculation is 3,942,000 blocks / 2,700 blocks per day = 1,460 days, or 4 years (not considering leap years).

Qtum’s first halving calculation is a little more complicated because Qtum Chain launched with 144-second blocks, then hard forked to 128-second blocks, and finally hard forked to 32-second blocks. The halving block height will be 1,427,004, and then at every 3,942,000 additional blocks going forward.

The first halving will be coming on December 1, 2021, at approximately 11 am GMT.

Qtum halvings drop the subsidy to zero in 2045. The chart below shows how the supply grows over time, with halvings and subsidies, and the maximum capped supply of 107.8 million reached in 2045.

Previously, Partick Dai pointed to how, A cross chain bridge based on zk-rollup should be a good idea. By this way, Qtum can connect with BTC and ETH directly. And Qtum can be the side chain for BTC and ETH same time. Enable more possibilities.

Qtum builds on the transaction model of Bitcoin and connects this on its own blockchain with the smart contract functionalities of Ethereum.

Qtum is like a test field for fundamental innovations of our industry. We tested smart contracts for bitcoin and we tested Proof of Stake for Ethereum. All these tests showed great possibilities since Qtum Day 1 in 2017. Then few years passed, still.

As a bitcoin miner since 2012, I know many Bitcoin OG want keep bitcoin simple and stable. But every tech need embrace the young people and the next generation. Bitcoin is gold now. It’s not a peer to peer cash any more.

It’s a big pity Bitcoin cannot support smart contracts, otherwise with all the Layer2 tech, we can scale bitcoin TPS to 1000-2000, without any security compromise. Then, I believe bitcoin will become the world currency sooner and easier. Every one can release NFT on Qtum. A super decentralized and Green blockchain platform.

Qtum is a Green version of BTC. We maintained all the latest updates of bitcoin code and added a lot great features on Qtum. (Smart contracts for BTC).

Community Response:  Why did Qtum drop so heavily? Seems to be a good project isn’t it?

Qtum is an environment friendly and GREEN Version of Bitcoin and Ethereum. A totally decentralized POS platform.
