<div dir="ltr">This is a very useful BIP, and I am very much looking forward to implementing it in Mycelium, in particular for bip32 wallets.<div>To me this is not about whether to use SSS instead of multisig transactions. In the end you want to protect a secret (be it a HD master seed or a private key) in such a way that you can recover it in case of partial theft/loss. Whether I'll use the master seed to generate keys that are going to be used for multisig transactions is another discussion IMO.</div>
<div> <br><div>A few suggestions:</div><div> - I think it is very useful to define different prefixes for testnet keys/seeds. As a developer I use the testnet every day, and many of our users use it for trying out new functionality. Mixing up keys meant for testnet and mainnet is bad.</div>
<div> - Please allow M=1. From a usability point of view it makes sense to allow the user to select 1 share if that is what he wants.</div><div><br></div><div>I have no strong opinions of whether to use GF(2^8) over Shamir's Secret Sharing, but the simplicity of GF(2^8) is appealing.</div>

Obviously rolling your own is always an option. Are you just saying that Base58 encoding and decoding is easier than Shamir's Secret Sharing because the divisors are small?<br>

</div>Well, yes, to be fair, in fact it is. The small divisor and lack of<br>
modulo arithmetic make base-58 encoding and decoding noticeably<br>
smaller and easier than Shamir's Secret Sharing over GF(P256).<br>
