Primavera De Filippi is a everlasting researcher on the CERSA/CNRS/Université Paris II, a school affiliate on the Berkman-Klein Center for Internet & Society at Harvard Law School, the “alchemist” for DAOstack and a co-author of “Blockchain and the Law.”
Much dialogue is presently happening in regards to the nature and specificities of blockchain governance, however once we say “blockchain governance” we’re actually speaking about a number of issues.
While individuals typically use the time period to explain the mechanism by which the underlying protocol of a blockchain-based community may be modified or up to date – when it comes to each on-chain and off-chain governance – we focus right here on a wider query:
What are the varied parts or forces that affect the governance of blockchain-based networks or purposes?
Harvard professor Lawrence Lessig identifies 4 totally different forces that affect conduct: regulation, social norms, markets, and structure (i.e., technical infrastructure or code). In doing so, he underlines the truth that we can’t focus solely on the principles particularly designed to control or regulate one specific particular person.
Rather, we have to take a bigger ecosystemic strategy, taking a look at numerous forces that affect that particular person. Accordingly, in terms of selling or precluding sure behaviors, we’d select to immediately regulate people by way of the authorized system or not directly regulate them via one of many different three forces (markets, social norms, and structure).
We suggest such an ecosystemic strategy to determine the totally different levers that would affect the operations of a blockchain-based system and the extent to which these levers contribute to the broader notion of “blockchain governance.”
Blockchain-based purposes don’t exist in a vacuum. They subsist inside a bigger ecosystem of web purposes, every working in response to its personal protocols and guidelines.
The web layer
In specific, the operations of a blockchain-based system – whether or not it’s a blockchain-based community, platform, or software – are outlined by the principles that govern these methods but in addition reply to the totally different layers of the web infrastructure, which to a special extent contribute to shaping the methods’ general governance.
Specifically, blockchain-based networks like bitcoin and ethereum function on prime of the web and finally rely upon protocols just like the TCP/IP, which is liable for routing and transferring packets of data between totally different nodes on the community. These blockchain-based networks thus can’t function with out web connectivity.
Most critically, as a result of web service suppliers (ISPs) finally management the transportation layer of the web, they might discriminate towards packets coming from or directed towards a blockchain-based community, successfully tampering with its operations.
Internet governance can subsequently have a big impression on the operations of a blockchain-based community. Particularly related on this context is the “net neutrality” debate. The apply of packet discrimination makes it attainable for ISPs to favor sure blockchain-based networks, on the expense of others.
More radically, if a authorities have been to ban a specific blockchain-based community, it might require all ISPs working inside its nationwide boundaries to dam or filter visitors coming from or directed to that community – e.g., by way of mechanisms resembling deep packet inspection (DPI) or different visitors detection methods.
Accordingly, whereas web governance is exterior to the blockchain ecosystem (in that its scope is far broader), regulating the web infrastructure might not directly have an effect on the operations of a blockchain-based system.
The blockchain layer
Similar issues emerge inside a singular blockchain-based community.
While ISPs are answerable for routing packets by way of the web, based on particular protocols (e.g., TCP/IP and BGP), miners on a blockchain-based community are answerable for validating and recording transactions into the underlying blockchain, in line with a specific protocol (e.g., the bitcoin protocol), consensus algorithm and fork-choice (e.g, bitcoin’s proof-of-work protocol stipulates that miners ought to all the time add to the “longest chain” as outlined by the quantity of hashing energy required to compute the chain).
Today, this activity of processing transactions is pushed principally by an financial incentive system, whereby the upper the transaction charges paid to the community, the larger the prospect for these transactions to be included into the subsequent block.
But transaction charges and mining rewards – albeit a elementary incentive for miners – usually are not the one elements which may affect the conduct of miners. Other levers may come into play, stemming from the surface of the blockchain infrastructure.
- Markets: What would forestall a big mining pool from getting into into an (off-chain) settlement with third events, so as to velocity up the inclusion of sure transactions on the expense of others.
- Social norms: Could miners collectively agree that particular transactions coming from or directed in the direction of a legal dapp [decentralized application] won’t be processed right into a block?
- Laws: Could regulators stipulate that each one miners situated particularly jurisdictions are prohibited from validating transactions pertaining to a selected dapp or account?
- Architecture: Might the Great Firewall of China be constructed to restrict the power of miners in China to deal with bigger blocks?
These exterior forces, present past the management of any given blockchain-based software, might drive radical penalties over the operations of that specific dapp.
The software layer
It turns into clear that the governance of a specific blockchain-based community might immediately or not directly have an effect on the operations of a specific blockchain-based software operating on prime of that community.
Even if dapps may be designed to be utterly autonomous–in the sense that no single get together has the facility to regulate or affect their operations–they continue to be affected by the operations of the underlying blockchain community and the precise set of protocols that set up its modus operandi.
The governance of a blockchain-based community might be leveraged towards censoring a few of the transactions directed to those dapps, and even altering their operations by modifying their code by means of a tough code.
This is exactly what occurred after The DAO hack, when three.6 million ether have been drained from The DAO’s account as a result of a code vulnerability. The ethereum group responded by intervening with a coordinated motion to switch the ethereum blockchain protocol. By transferring funds from The DAO to a different sensible contract, a mechanism was offered for returning the siphoned funds again to the unique house owners.
This excessive treatment has been closely criticized. Some noticed it as a betrayal of the “immutability” and “incorruptibility” of the ethereum blockchain (i.e., the “code is law” paradigm).
Going deeper into the stack, there are the varied blockchain-based platforms on prime of which individuals can deploy their very own dapps.
Some dapps sit immediately on prime of a blockchain-based community. For example, Gnosis is carried out as sensible contracts on the ethereum blockchain. Others are deployed on prime of a dapps framework corresponding to DAOstack, which implements its personal protocols for creating and sustaining dapps.
While most decentralized blockchain-based purposes come with their very own units of guidelines, additionally they rely and subsequently should comply with the principles of the platform on which they function. This might give rise to 2 distinct forms of issues.
One is that if there’s a flaw in certainly one of these sensible contract platforms, the flaw will have an effect on all blockchain-based purposes that depend on the platform. Recall the bug in Parity’s multisignature sensible contracts, which led to the theft of over $30 million value of ether, adopted by a subsequent assault on Parity’s revised multisignature sensible contract code, which had been delivered to “selfdestruct,” thereby freezing the funds in all multisig wallets that trusted this shared code.
Another drawback emerges by development, when platforms implement “proxy” contracts that delegate calls to different sensible contracts, which may be up to date by the platform builders. While such practices are nonetheless unusual, some platforms (e.g. Zeppelin Solutions) are beginning to experiment with proxy libraries in order that, every time one of many underlying features is modified, all dapps counting on these libraries will mechanically inherit these modifications.
While this supplies many advantages when it comes to flexibility and upgradability, such a design may be problematic to the extent that it depends on a trusted authority (i.e., the sensible contract platform operator) that would arbitrarily affect the operations of those so-called decentralized purposes.
(Note that the DAOstack framework doesn’t truly present such a function. The set of sensible contracts offered by the framework, as soon as deployed, can’t be arbitrarily modified by the platform operators. While DAOstack may, over time, supply a collection of upgrades to a few of the platform’s sensible contracts, these upgrades can’t be mechanically carried out with out the consent of the platform’s customers.)
With this in thoughts, we’d reframe our understanding of “blockchain governance” to incorporate not solely the principles particularly meant to manage the operations of a specific blockchain-based community or software, but in addition the principles that contribute to regulating the underlying infrastructure on which these blockchain-based methods function – which themselves function on prime of one other infrastructure, and so forth.
As the saying goes, it’s turtles all the way down.
