Browsers are bad places for crypto. 30 | 31 | Also - this SPV node connects initially to the [HNScan](https://hnscan.com/status) node, which serves BIP37 light clients. 32 | This peer is hard-coded because, again, this is just a proof-of-concept for testing. 33 | -------------------------------------------------------------------------------- /bitcoinlogo.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/pinheadmz/mobilehsd/bbd6808df5750297c5f6c4710da858991d9a2965/bitcoinlogo.png -------------------------------------------------------------------------------- /browser.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | hsd SPV Node 9 | 10 | 11 |

15 | This server provides these services to the Handshake network:
16 |

hsd full node
17 |
18 | This full node is one of the network seed nodes, meaning its location 19 | is hard-coded in the software. It supports up to 128 incoming connections 20 | and BIP37 (SPV) connections.
21 | 22 | aonetsezqp4m52w4jpfq2gv3dggy2wqfwqtkfjyttgdidbvhgp5as@165.22.151.242 23 | 24 |
25 |
26 |
DNS-over-HTTPS server
27 |
28 | You can use this server as a trusted resolver, making DNS requests over 29 | HTTPS that resolve to the local Handshake full node. You can try it out 30 | by configuring Firefox's 31 | TRR Settings 32 | in 33 | about:config

Handshake DNS seeder
44 |
45 | easyhandshake.com runs an authoritative nameserver over the subdomain 46 | seed 47 | anchored by NS Records in the ICANN DNS system. It returns A and AAAA 48 | records generated from the hostlist of the local full node, so bootstrapping 49 | nodes can find more peers on the network. You can request those records 50 | from any legacy DNS resolver:

54 |
Web browser SPV node
55 |
56 | Because hsd is written in JavaScript, it can be repackaged for use in a 57 | web browser. The entire SPV node runs in the browser, storing block 58 | header data in the browser's application storage. Easyhandshake provides 59 | a proxy server to connect the webapp to the p2p network. Some explanation 60 | is provided in this 61 | bcoin guide. 62 | Remember, the web browser is not a secure environment for crypto 63 | operations. It's just a proof-of-concept for now, but it does allow 64 | web clients to make DNS requests to the live Handshake network.

65 | Launch the in-browser SPV Handshake node! 66 |
