26 June 2018   1779

The developer of bitcoin and blockchain solutions, Blockstream, presented a beta version of c-lightning (v0.6), which is one of the main implementations of the Lightning Network protocol.

The company blog says that the new version of the c-lightning solution is based on a new architecture that is modular, as well as more flexible and scalable.

In particular, in version 0.6 c-lightning implemented:

  • Lightweight nodes: Previous releases required a full bitcoind node running alongside c-lightning, to provide access to the Bitcoin network. This release still requires the bitcoin-cli utility to be present, but it can now talk to remote nodes as well, including some lightweight nodes such as spruned.
  • The gossip protocol has been updated to use a more lightweight bandwidth mechanism that asks for specific information, rather than exchanging full network views as the previous release did. This is particularly important for low-powered and mobile devices that would otherwise spend a lot of bandwidth and energy downloading and verifying information they already have.
  • API stability: The c-lightning JSON-RPC interface and supporting libraries have been redesigned in order to minimize changes in future releases. This API stability should make it easy for other projects to build on top of c-lightning because we will support this version of the API for the foreseeable future, maintaining backward compatibility, should we introduce any changes.
  • Wallet and sync: c-lightning now includes a full-fledged wallet that manages both on-chain and off-chain funds. There is no more raw transaction handling! All funds are automatically tracked and returned to the internal wallet as soon as possible, with no user interaction required. In addition the blockchain tracking now maintains an internal view of the blockchain, ending long blockchain rescans.
  • TOR support: c-lightning now supports connecting to nodes over the TOR network, auto-registering as a hidden service, and accepting incoming connections over TOR.
  • The payment logic has undergone a major overhaul to support automatic retries for routing failures, randomization of route selection, and better feedback about the current state of a payment.

Director for Strategic Development Blockstream Samson Moe noted that to date there are already three beta versions of the main implementations of the Lightning Network protocol - Eclair, lnd & c-lightning.

He also stressed that since the launch of the Blockstream Store in January, the Lightning Network has grown by more than 16 000% and currently it has 7,800 payment channels.

BNC to Monitor BTC Community's Mood

Blockchain-based New Zealand-based research firm Brave New Coin (BNC) has unveiled a new system for measuring the mood of the Bitcoin community based on Twitter messages.

According to BNC, the new Twitter Sentiment rating system analyzes over 34 million BTC-related Twitter posts each week. The company uses artificial intelligence (AI) algorithms that look for records containing the words bitcoin, $ BTC and BTC and others.

BNC notes that user sentiment continues to be a “significant” factor in the price and dynamics of digital assets, and a new technique has been developed to track these sentiments. According to the BNC, it took 18 months to launch the Bitcoin Twitter Sentiment. The data obtained is divided into seven categories - Opinion, Technical Information, Inside the Network, Advertising, Bots, Macros and Hacking.

For the week ending January 17, the most common entries were in the Opinion category - their number was 30.42% of all data received. In second place was the category Technical Information, and in third inside the network (includes information on mining and hashrate).

BNC spokeswoman Pierre Ansaldi said that during the first quarter of this year, the company will also launch community sentiment analysis tools for other crypto assets.
