My first post here, hope I'm following the right conventions. I had this humble idea for a while, so I thought to go ahead and propose it. BIP: XX Title: URI scheme for Blockchain exploration Author: Marco Pontello Status: Draft Type: Standards Track Created: 29 August 2015 Abstract ======== This BIP propose a simple URI scheme for looking up blocks, transactions, addresses on a Blockchain explorer. Motivation ========== The purpose of this URI scheme is to enable users to handle all the requests for details about blocks, transactions, etc. with their preferred tool (being that a web service or a local application). Currently a Bitcoin client usually point to an arbitrary blockchain explorer when the user look for the details of a transaction (es. Bitcoin Wallet use BitEasy, Mycelium or Electrum use Blockchain.info, etc.). Other times resorting to cut&paste is needed. The same happens with posts and messages that reference some particular txs or blocks, if they provide links at all. Specification ============= The URI follow this simple form: blockchain: <hash/string> Examples: blockchain:00000000000000001003e880d500968d51157f210c632e08a652af3576600198 blockchain:001949 blockchain:3b95a766d7a99b87188d6875c8484cb2b310b78459b7816d4dfc3f0f7e04281a Rationale ========= I thought about using some more complex scheme, or adding qualifiers to distinguish blocks from txs, but in the end I think that keeping it simple should be practical enough. Blockchain explorers can apply the same disambiguation rules they are already using to process the usual search box. From the point of view of a wallet developer (or other tool that need to show any kind of Blockchain references), using this scheme mean that he can simply make it a blockchain: link and be done with it, without having to worry about any specific Blockchain explorer or provide a means for the user to select one. Blockchain explorers in turn will simply offer to handle the blockchain: URI, the first time the user visit their website, or launch/install the application, or even set themselves if there isn't already one. Users get the convenience of using always their preferred explorer, which can be especially handy on mobile devices, where juggling with cut&paste is far from ideal.

I would recommend 2 changes though. First, using a real URI scheme, blockchain:// so that we can just use normal URL parsing libraries. The bitcoin: thing leads to additional code to mutate it into a proper URI before passing it to URL parsing. And I think it would be fine to include the type looking up. For example: blockchain://blockhash/00000000000000001003e880d500968d51157f210c632e08a652af3576600198 blockchain://txid/3b95a766d7a99b87188d6875c8484cb2b310b78459b7816d4dfc3f0f7e04281a blockchain://block/189000 blockchain://address/1RicMooMWxqKczuRCa5D2dnJaUEn9ZJyn I think this would help the URI be more human understandable as well as give the explorers the ability to optimize a bit what they are looking for when hitting various databases. A possible future path could also include blockchain://tx/123000/4 for block height, tx index... Another possibility could be blockchain://version which would return a list of supported paths, version of the BIP supported, etc. The BIP should also specify little endian searching.

However, if you look at section 3 of the RFC, the first hierarchal level (which in http is used to describe hosts) can be any "authority", not necessarily a hostname. So, you could use tx, block, address, etc. as the authority for their paths.

That's obviously a design mistake in FTC, but it's not unsolvable. FTC could move their genesis block to the next block (or the first one that is not identical to LTC's). Bitcoin and all its test chains have different genesis blocks, so I'm not sure FTC should be a concern for a BIP anyway...

That's a very sweeping generalisation indeed. Why should two chains have to have a separate genesis? It's cleaner, but it's certainly not a necessity. You cant exclude this case just because it doesn't fit your concept of neat and tidy. Other BIP proposals that account for alternative chains do not rely on the genesis hash, but instead an identifier. Why should it be any different here? How would you account for a world with XTCoin and Bitcoin which would also share the same genesis hash, but clearly not be the same coin. When I brought up the issue originally, I deliberately steered away from altchains choosing to focus on networks like mainnet, testnet because I think it's easier to repurpose a protocol for an altcoin than it is to make the proposal work for all cases. Take the payment protocol for example. The BIP specifies a URI with bitcoin: well it's just as easy to repurpose that for litecoin: etc than adding something like ?cointype=litecoin, so that was my reason for not mentioning altcoins at all. If the proposal is made to account for altcoins, genesis hash is definitely not desirable, or at least not genesis hash in isolation, and if that's the case, better to have an identifier. ^ permalink raw reply [flat|nested] 32+ messages in thread

That's why I say petname, because no dictionary of supported chains should be considered universally accepted and thus it will always be just a local registry. If we're chainPetName is supported, there should be an additional call to query that local list. For example: blockchain:/chains JSON response: { "main": "000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f", "test": "000000000933ea01ad0ee984209779baaec3ced90fa3f408719526f8d77f4943", "regtest": "0f9188f13cb7b2c71f2a335e3a4fc328bf5beb436012afca590b1a11466e2206"} It may be problematic when too many chains are supported. For example, #6382 introduces std::numeric_limits<uint64_t>::max() new chains.

Much shorter, just as distinct. Obviously 4 bytes is not "as distinct" as 32 bytes. In #6382, std::numeric_limits<uint64_t>::max() new chains share the same magic bytes. And again, there's no central authority to register unique magic bytes. In contrast, producing a unique genesis block is trivial (look how I produced std::numeric_limits<uint64_t>::max() new unique genesis blocks in #6382). > I'd still prefer a common network name mapping for the sake of humanity.

This BIP could simply define one string name alias for each > supported network and leave mapping to local lingo to the implementors. There's many altcoins that call "testnet" to their own testnet. In Bitcoin itself, we've been using "testnet" to refer to the original testnet, testnet2 and testnet3. But again, the main issue is that we don't want a central authority to register unique unique and memorable chain name strings.

Why not? There's a central registry of MIME types. And there's a central registry of TCP/UDP port number assignments. The BIP describing the "blockchain" URI scheme is published by a central authority. For cases where assigning names to numbers is uncontroversial, central authorities don't cause any problems. ^ permalink raw reply [flat|nested] 32+ messages in thread

Sorry for having missed bip44 for review but that section is horrible in my opinion (see the links above). And it seems to be incompatible with bip001 which says are immutable once accepted (assuming that document is expected to be the central registry of registered chains). > How would you account > for a world with XTCoin and Bitcoin which would also share the same > genesis hash, but clearly not be the same coin. Schism hardforks are explicitly renouncing to reach consensus with all previous users. You're intentionally divorcing 2 chains, and you can do that without confusing users. In BIP99 the recommended deployment path for a schism fork is to simply use the nHeight for activation. The 95% miner's upgrade confirmation is not used here (like in uncontroversial hardforks and softforks) because you don't necessarily expect all miners to move to your side of the schism (and you don't want to wait for them, specially if it's an "anti-miner" hardfork). To avoid confusing users, you can define a new "genesis block" to use for the chain ID, for example, 1000 blocks before the activation height. The same applies for potentially pre-mined altcoins that haven't had the decency/competency of even changing the string in pszTimestamp. For example, FTC, coins generated with coingen (Matt Corallo or the current owner may want to correct me on this point) or elements alpha (https://github.com/ElementsProject/elements/blob/alpha/src/chainparams.cpp#L115). Fortunately alpha has a unique chain ID because it was changing both the block and transaction serialization formats anyway. But hopefully we will fix that for beta and later sidechains. All chains that want a unique chain ID can have it retroactively. At worst, they may need to use the hash of a block that is not the genesis block. In other words, they may need to move their "genesis checkpoint" upwards. Terminology may make things more clear. We can replace: "The chain ID is the hash of the genesis block" with "The chain ID is the hash of the genesis checkpoint". If we want a unique chain ID we can have it: it just cannot be memorable at the same time. And each chain and implementation can start using them (in addition to petname -> chain ID local dictionaries) at any point in time: this is retroactively (and obviously forwards) compatible. There can be many competing registries for the name -> chainID dictionaries (maybe one of them based on namecoin?) but bitcoin/bips shouldn't maintain one. ^ permalink raw reply [flat|nested] 32+ messages in thread

Yes, sorry about the link. I guess you can point to #6230 . I can rebase it if needed but I would close it again because I don't want to have too many things from #6382 opened at the same time (is noisy and worse for review). My plan was to not open it independently at least until after #6907 (and actually after 0.12 assuming #6907 gets in by 0.12). But then I would maybe open a new one and reference the old one rather than reopening #6230 (which tends to be confusing). I'm not really sure what's the best answer here...but #6382 is certainly going to need rebase and the link will be broken again. Maybe one answer is to copy some text from #6230 or the commit and add it directly to the BIP instead of referencing to that commit (which will be, at least until #6907 is merged, a moving target).
