Hi Justin, Your lookup solution is indeed more efficient than OpenAlias, and more robust to DoS. However, that is not because you use a two-tier lookup. Indeed, instead of having the following records: _wallet.sample = "btc ltc" _btc._wallet.sample = "mybitcoinadress" you could simply have: _wallet.sample = "btc ltc" _btc.sample = "mybitcoinaddress" In practice, a wallet supporting only Bitcoin will skip the currencies lookup in both cases, and go directly for the _btc record. One benefit of having an intermediate "_wallet" level is to allow zone delegation. Is that the reason for that choice?
