Goog morning ZmnSCPxj,
> Unless of course you propose to have the sidechain issue its own coin, in > which case it is not much more than an altcoin. Okay, call it an altcoin consensus mechanism. Because sidechains do have to issue their own coins. Still, I am not proposing independent altcoins. Bitcoin is the only unit of account. I am proposing bitcoin derivatives only as means of bitcoin transfer. Think of gold vs cash. > Still, the real-world value of the total block rewards for that altcoin > will have to match the real-world value of the total block rewards of Bitcoin > in order to have security even approaching Bitcoin. My point is that, assuming equal rewards, PoW and bitcoin-backed PoS do offer the same level of security. So in theory, you are right. In practice, a sidechain does not need to be as secure as bitcoin. It requires only a sufficient user base. Thanks again for your detailed answer, -Robin _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
