<p>The Classic Multi-Sig Wallet is a 2 of 3 and is a special case of a Consensus Account. I think 2 of 3 is the sweet spot for multi-sig.

<p>An interesting use case would be a 3 of 6 where one person holds 3 keys and 3 people each hold 1 key. In this way one person could control their own money, but the funds could still be recoverable even if the primary key holder were to disappear with all of his keys. As n increases, the level of trust in the secondary parties can decrease. A good use case might be a family savings account that would just automatically become an inheritance account if the primary account holder were to die.</p>

<p>Your scenario sounds similar to the design of HD wallets. <a href="https://bitcoinbook.info/" rel="nofollow noreferrer"><em>Mastering Bitcoin</em></a> introduces them in chapter 4 as:</p>

<blockquote>
  <p>The most advanced form of deterministic wallets is the hierarchical deterministic wallet or HD wallet defined by the BIP0032 standard. Hierarchical deterministic wallets contain keys derived in a tree structure.....</p>

<p>With a high-level example application:</p>

  <p>Branches of keys can also be used in a corporate setting, allocating different branches to departments, subsidiaries, specific functions, or accounting categories.</p>

<p>From what I understand, the child / grandchild are fully functional as individual keys for their own wallets. They <strong>do not</strong> and can not unlock parent accounts. Whereas the root / parent always has the ability to access descendant / children. In this structure, the root / parent does not share its wallet. The child wallets are shared to the parent. So it isn't sharing fully the one wallet between multiple parties. It's sharing in one direction.</p>

<li>Of course, you can hold the bitcoin wallet from different devise. Cause of that you can recovery your bitcoin account in any wallet if you control the private key.</li>
<li>When you receive money， you need not create a new wallet. You just need create a new bitcoin address. Each people hold their own bitcoin address. As  杜興怡 says, you can use a HD wallet which can create sub private key and sub public key.</li>

<p>I'm trying to get my Rugby Club involved in Bitcoin. </p>

<p>I'm really looking for ideas on the easiest way to integrate BTC at the bar. Is it possible to have a single wallet for the Club accessible from multiple devices? </p>

<p>I would need bar payments to go into one overall account or wallet somehow, as the responsibility for running the bar falls to different people every weekend.</p>

<p>I dont want to risk 20 different wallets being used, and some people not forwarding the relevant bitcoins on to a central wallet at the end of night. </p>

<p>Any ideas on a work around?</p>

<p>Many thanks,

(Asked by: username_0 on 2017-02-17)

I'm trying to get my Rugby Club involved in Bitcoin.

I'm really looking for ideas on the easiest way to integrate BTC at the bar. Is it possible to have a single wallet for the Club accessible from multiple devices?

I would need bar payments to go into one overall account or wallet somehow, as the responsibility for running the bar falls to different people every weekend.

I dont want to risk 20 different wallets being used, and some people not forwarding the relevant bitcoins on to a central wallet at the end of night.

Any ideas on a work around?

Many thanks,

1. Of course, you can hold the bitcoin wallet from different devise. Cause of that you can recovery your bitcoin account in any wallet if you control the private key.
2. When you receive money， you need not create a new wallet. You just need create a new bitcoin address. Each people hold their own bitcoin address. As 杜興怡 says, you can use a HD wallet which can create sub private key and sub public key.

Electrum wallet maybe a good choice or you can use Bitcoin-core wallet to generate different bitcoin addresses.
