If you actually\nreversed 2-3 weeks of transactions, then the Bitcoin price would fall,\ndestroying the value of the additional coins you managed to obtain.  Even\nif their was no price fall, you can only get a fraction of the total.\n\n\nI would replace \"Bitcoins you manage to steal\" with \"Bitcoins you manage to\ndouble-spend\". Then, it still seems the same to me.\n\n\nWith BMM, you can \"buy\" the entire reserve of the sidechain by paying\n(timeout) * (average tx fees).  If you destroy a side-chain's value, then\nthat doesn't affect the value of the bitcoins you manage to steal.\n\n\nIt may destroy great value if it shakes confidence in the sidechain\ninfrastructure. Thus, the value of the stolen BTC may decrease, in addition\nto the lost future tx fee revenues of the attacked chain.\n\nhttp://www.truthcoin.info/blog/drivechain/#drivechains-security\n\nIn my view, sidechains should only exist at all if they positively impact\nBitcoin's value. It is therefore desirable for miners to steal from chains\nthat provide no value-add.\n\n\n\n\n\u003e In point of fact, the transactions *are* validated...by sidechain full\n\u003e nodes, same as Bitcoin proper.\n\u003e\n\u003e\nThe big difference is that Bitcoin holds no assets on another chain.  A\nside-chain's value is directly linked to the fact that it has 100% reserves\non the Bitcoin main chain.  That can be targeted for theft.\n\n\nAgain, I don't really think it is that different. One could interchange\n\"recent txns\" (those which could be double-spent within 2-3 weeks) with\n\"sidechain deposit tnxs\".\n-------------- next part --------------\nAn HTML attachment was scrubbed...\nURL: \u003chttp://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20170522/8a42bd04/attachment.html\u003e"}
