What might happen if one day Bitcoin becomes PoS?

Bitcoin is a protocol that uses Proof-of-Work (PoW) as a consensus mechanism. This is an involving mechanism considerable energy consumption which increases as the value of BTC increases, but at the same time guarantees the high immutability of its blockchain.

Other cryptocurrency protocols, on the other hand, use Proof-of-Stake (PoS) because it is a less energy-intensive mechanism and allows faster block generation. However, he is a little less secure than PoW.

For example, Ethereum was born with PoW, but then over the years it decided to switch to PoS. Could something similar happen to Bitcoin?

What if Bitcoin became a PoS system?

To date, the answer is definitely no.

Indeed, no one has the power to arbitrarily modify the Bitcoin protocoland right now there isn’t a large majority of Bitcoin users who would accept such a radical change.

To change from PoW to PoS requires a complete change of the system with which the blocks are created, so much so that, for example, Ethereum even had to create a new PoS-based blockchain, deciding to abandon the old one based on PoW once the last step is performed.

Perhaps the conditional is a must, in a relatively distant future also for Bitcoin a strong majority of users could arise, who would approve such a radical change, but to date we cannot even glimpse this scenario.

Furthermore, although some argue that Bitcoin’s energy consumption will continue to increase at high rates until the switch to PoS is needed, in reality, however, in the long run, Bitcoin mining energy consumption is likely to decrease. because of the continuous halving the miners’ rewards once every 4 years.

That said, no one, however, forbids imagining in a purely theoretical way what the switch of Bitcoin to PoS could entail.

In fact, it’s not that difficult. In fact, if it were decided to replace PoW with PoS also on Bitcoin, the process could also be very similar to that done by Ethereum.

However, PoW allows the block time, on which The monetary policy of Bitcoin depends, to be kept very constant over the years: every 10 minutes a block and a halving of premium BTC are formed every 210,000 blocks, or just under 4 years. With PoS it might be more difficult to keep this monetary policy fixed and rigid.

The main results on Bitcoin if it were to switch from PoW to PoS

The disadvantages of the Proof of Stake

The move to PoS would therefore create significant differences between the nodes with more BTC staking and the others. Right now, however, Bitcoin’s roughly 10,000 public nodes are all the same, all with the same power. PoS, on the other hand, inevitably leads some nodes to manage multiple tokens, in fact making them a little more “powerful”.

It would definitely make miners disappear as PoS doesn’t involve extraction. This it would suddenly and drastically reduce energy consumptionwhich is currently perhaps the biggest problem for Bitcoin.

The fact that PoS gives slightly lower security than PoW, on the other hand, may not even be that significant, because the current security level is so high that perhaps even a slightly lower degree could be considered tolerable.

Instead, the fact that PoS protocols are often less decentralized could be a problem for Bitcoin, for example, if a few large nodes were formed with huge amounts of BTC immobilized in staking, and therefore with great decision-making power.

Perhaps this is one of the main reasons why most Bitcoin users do not want changes to the underlying protocol, because the high degree of decentralization of Bitcoin is precisely one of its greatest strengths, to be protected and maintained as much as possible.
