Many good people there. I am co-author of TLS, former Certicom CTO, and now working with blockchain and smart contracts.
Good idea. Hey @ChangeTip: send $1 to @DirectRelief for vitamins for #OneSafePregnancy. https://twitter.com/bitcoinmom/status/635653562937290752
Here is the actual @Blockstream docs by @pwuille for Threshold Tree Signatures — some really useful code here! https://blockstream.com/2015/08/24/treesignatures/
Fascinating discussion tonight w/ Pieter Wuille @pwuille & Gregory Maxwell re: using #bitcoin’s script in digital certificates & #RevokeSSL
Interesting is also @pwuille’s EC lib supporting Pedersen commitments, borromean ring signatures & ZK range proofs https://github.com/ElementsProject/secp256k1-zkp
Here are more details about those features in the commit comments: https://github.com/ElementsProject/secp256k1-zkp/commit/71ed475ea53ff4576b7344762584b752a824c60f
Very cool — @BlocksStream’s Elements supports Schnorr signatures on secp256k1—I ♥️ Schnorr sigs: https://github.com/ElementsProject/elementsproject.github.io#schnorr-signature-validation #bitcoin #sidechain
I get geeky about the opportunities offered by Schnorr signatures to allow us to do interesting multi, group, threshold, & ring signatures.

I’ve been talking to Packet Clearing House (a non-profit) about securing BGP routes with blockchain backed proof-of-existence.
Replying to @NickSzabo4
From what I have found, little has change with BGP since this survey paper in 2005: http://www.patrickmcdaniel.org/pubs/td-5ugj33.pdf
Replying to @NickSzabo4
There is a new (2/15) RFC on BGP Operations and Security http://tools.ietf.org/html/rfc7454 but it really doesn’t add crypto.
Replying to @NickSzabo4
There is a 2012 RFC for a PKI to secure BGP http://tools.ietf.org/html/rfc6480 but it uses X.509 certificates w/ root signed by IANA.
ChainPoint is about the 5th I’ve seen of these merkle-tree w/root on the #blockchain. We need an common standard. https://twitter.com/jgarzik/status/634747387198750720
I’m intrigued by Eris. It was a permissioned #blockchain version of Ethereum, but now is more agnostic & can do both https://twitter.com/prestonjbyrne/status/634300573911777280

A new #Ethereum block explorer service from @TradeBlock, but what I want is a #SmartContracts explorer https://tradeblock.com/blog/tradeblock-launches-ethereum-blockchain-explorer

You can consider Bitcoin’s script language vm a powerful generalized digital signature tool. But what to call it used outside of #Bitcoin?
RT @petertoddbtc: Bitcoin relies on the security assumption that information is easy to spread and hard to censor. #blocksize

Zaki Manian @zmanian suggests a EVM bytecode language like #Bitcoin is a forth-like stack + crypto-primitives & could be called “Forthright”
