here<\/a>.<\/p>\n\n\n\nRetraining Bitcoin<\/h2>\n\n\n\n In the introduction we described the Quasar upgrade as being very limited in scope. That\u2019s not entirely true. From a technical point of view the changes are limited but its role in the lead up to the Genesis upgrade is much more important that it may seem on the surface.<\/p>\n\n\n\n
Some will no doubt ask \u201cwhat if a malicious party mines blocks larger than 512mb just to cause trouble\u201d. Well I hope they do because it will be the first real life demonstration of the power of Nakamoto consensus as a capacity governance tool.<\/p>\n\n\n\n
This upgrade represents a very significant cultural shift for Bitcoin. By separating the default hard cap (developer chosen) from the consensus hard cap (miner chosen) we are diluting the power of the default setting which can only be set by a single group (us). This is a very active effort by the Bitcoin SV development team to push the responsibility for capacity consensus out of their own hands and into the hands of miners. The miners are now responsible for managing block size consensus and if they screw it up it will cost them. The final stage in that transition is removing the default altogether next year (or rather the default will be infinite). But we think it\u2019s fair to give the miners time to get used their new role and we also need a bit more time to give them better tools to manage uncapped block sizes more safely.<\/p>\n\n\n\n
Putting aside miners for a moment, there is another consideration. Operators of blockchain listeners are slowly getting used to the idea that they need to make peace with orphans and reorgs or at the least, if they can\u2019t make peace with it, learn how manage in an environment where they are normalized. It\u2019s not hard to do and we already have some of the tools to do it. But a reorg or two from time to time is a good reminder. This is another reason we are pushing businesses onto the STN. We want to break your services there. But reorgs don\u2019t really break services they seem to cause more of a mental shock to people who\u2019ve been listening to Core for too long. So if someone wants to mine 600mb blocks and try to cause some reorgs we\u2019re pretty happy for that to happen. It will do two things, it will help people in the ecosystem get used to reorgs as normal events and Nakamoto consensus will ensure the event costs some miner dearly which is also a thing they need to get used to.<\/p>\n\n\n\n
Bitcoin is a brutally Darwinian game. It is a reflection of the natural world in which some of the harsher realities are the very things that drive the strengthening of species and the global ecosystem that hosts them. Quasars are one the most brutal phenomena in nature and the Quasar upgrade is all about helping all Bitcoin participants to understand and adapt to those facts in preparation for the gloves coming off fully after the return to Genesis.<\/p>\n\n\n\n
