First of all, I think the security model for sidechains is the same as that of every blockchain People will say things, like "but with sidechains 51% hashrate can steal your coins!", but as I have repeated many times, this is also true of mainchain btc-tx. is something else? There are substantial opportunity costs as well as a collective action problem when it comes to re-writing the mainchain. Is there anything similar for drivechains? As far as I can tell there is no opportunity cost to casting a malicious vote, no repercussions, and no collective action barrier that needs to be overcome. Unless I'm missing something I wouldn't liken the security of a drivechain to that of the mainchain. --001a1147bce6ddd50f055f88d592 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable <div dir=3D"auto"><div><br><div class=3D"gmail_extra"><div class=3D"gmail_q= uote"><blockquote class=3D"quote" style=3D"margin:0 0 0 .8ex;border-left:1p= x #ccc solid;padding-left:1ex"><div class=3D"quoted-text">I think you are m= issing a few things.<br></div> <br> First of all, I think the security model for sidechains is the same as<br> that of every blockchain<br> <br> People will say things, like "but with sidechains 51% hashrate can ste= al<br> your coins!", but as I have repeated many times, this is also true of<= br> mainchain btc-tx. =C2=A0is something else?<br></blockquote></div></div></di= v><div dir=3D"auto"><br></div><div dir=3D"auto">There are substantial oppor= tunity costs as well as a collective action problem when it comes to re-wri= ting the mainchain.=C2=A0</div><div dir=3D"auto"><br></div><div dir=3D"auto= ">Is there anything similar for drivechains?
