- Beneath improvement by the LNP/BP Requirements Affiliation, the RGB protocol entered beta in June.
- The second layer community guarantees to deliver sensible contracts and tokenized property to Bitcoin with a Lightning Community-esque technical design.
- RGB could possibly be used to concern tokenize securities and nonfungible tokens (NFT), and to supply a extra personal technique of stablecoin issuance and switch.
Sensible contracts and Bitcoin. These technical phenomena are not often related to one another, actually because folks consider Bitcoin’s paired-down scripting language can’t assist the sensible contract purposes which have turn into the darlings of the Ethereum ecosystem.
However as the brand new sensible contract-enabling protocol RGB launches its beta, the parents on the LNP/BP Requirements Affiliation are attempting to vary this notion.
The group (whose acronym is brief for Lightning Community Protocol and Bitcoin Protocol) is constructing RGB, a sensible contract community constructed on high of Bitcoin. (The protocol is known as after the “RGB” additive coloring scheme as a result of it initially began as a challenge to enhance Bitcoin’s coloured cash scheme for tokenized property.)
The “third layer” community, as considered one of its architects, Giacomo Zucco, calls it, has entered beta and will assist outfit Bitcoin with the tokenizing capabilities which have made Ethereum the go-to blockchain for issuing tokenized property like securities, collectibles, crypto {dollars} and extra.

The brand new outdated factor
RGB was first conceptualized by Bitcoin Core developer and cryptography advisor Peter Todd. With undisclosed funding from Bitfinex/Tether, Fulgur Ventures and Poseidon Group, the protocol simply entered beta two months in the past. LNP/BP head Giacomo Zucco clarified that the “RGB node for the software program itself is in beta” however that each one RGB-compatible wallets are nonetheless in alpha.
The pursuit of Bitcoin-based sensible contracts – and extra usually, tokenizing property on Bitcoin – is nothing new.

Bitcoin’s OP_RETURN perform has allowed for restricted sensible contract performance because the coin’s inception. This perform set the technical groundwork for Bitcoin-based NFTs/collectibles by the Counterparty protocol, in addition to the issuance of the tether (USDT) stablecoin on Bitcoin by the Omni protocol.
For its personal half, the Lightning Community’s hash time-lock contracts – the technical parameters that lock bitcoin (BTC) into fee channels on the secondary community – are a type of sensible contract.
Leveraging strategies (and trade-offs) of Lightning
So-called “sidechains” are trusted blockchains within the sense {that a} federated physique of representatives run the nodes that oversee the sidechain’s operations, akin to issuing property and “pegging” bitcoin into the sidechain. These networks, working parallel to a decentralized blockchain like Bitcoin, market smart-contract capabilities as considered one of their main use circumstances.
RGB, alternatively, just isn’t a trusted blockchain like RSK or Liquid, nor does it depend on Bitcoin’s most important chain to execute transactions like Omni or Counterparty. As an alternative, its design is taken within the picture of its technical cousin, the Lightning Community.

The Lightning Community depends on “client-side verification” for its friends to confirm the motion of funds. Once you ship funds to a peer on Lightning, the “state” of the fee channel with this peer is up to date on each your Lightning node and your peer’s Lightning node. The ultimate state of the fee channel just isn’t recorded on Bitcoin’s blockchain till the channel is closed.
This delayed verification permits the Lightning Community to course of near-instantaneous funds, however this comes at a price: You will need to preserve your node working always or the peer on the opposite finish of your fee channel could attempt to cheat you by broadcasting a false channel state to the blockchain (a technical service often known as Watchtowers are working to mitigate this assault vector).
Zucco mentioned RGB “leverages the strategies and trade-offs of Lightning,” in that property might be transferred in the identical method.
“The RGB design is a client-side validation design. It implies that once I ship you one thing, I don’t publish the switch on the community; I ship it to you, peer-to-peer, and I’ll simply use the general public community to forestall double-spending. You must use the blockchain solely to forestall double-spending, however not for transferring property.”
He emphasised that the trade-offs are the identical as in Lightning and harassed that every RGB node might want to preserve backup information of its whole state.
To concern property on RGB, the issuer creates a “schema” for the asset that defines parameters like fungibility, circulating provide and inflation charge, amongst others. The asset and its schema are then anchored to a reference…
