Talk:BIP 0015

I think anything outside the blockchain is an additional security vulnerability.

My concept

Send 0.005 BTCs to 10 consecutive coinbase addresses in one trasaction (concept copied from ). Coins sent from address you want to use and include in script hex encoded address in any format - e.g. MyName or then a OP_DROP in the script (as per "bob" in (98*256*256+111*256*256+98=6451042) ). This would be called an "Address Initiation" transaction.


Clients would when they see an Address Initiation transaction store name/address pair locally. Could then translate names into addresses to send BTCs. Ordered nature of blockchain would ensure you can check your address is valid before telling anyone to use it.

Once large scale and implemented network wide

Clients send directly to nice addresses and network can lookup real address to receive when trying to spend.


  • There is a cost of creating an address so less spam addresses.
  • Cost is paid to miners who secure the network.
  • Does not require blockchain fork.
  • Any address format possible.
  • Now people can speculate on Addresses too! (or is that a disadvantage?).
  • As secure as Bitcoin.


  • A number of client changes needed to make user friendly.
  • Does not seem elegant.
  • Storage bloat (although would not be a problem for a long time).
  • More prone to typos (phelix)

Namecoin aliases

Aliases are stored in the namecoin blockchain, see :


  • Fast & easy to add into bitcoin : need an rpc request & json parsing
  • Benefits from all the bitcoin advantages
  • Secure : no external server/entity to trust
  • High availability : available even when offline
  • Easy to create & update an alias (possible offline too)
  • Namecoin Alias banks possible, like bitcoin banks


  • Need to run another software
  • Need to get some namecoins (or use a bank)
