That is Half three of a three-part sequence through which Andrew Levine outlines the problems dealing with legacy blockchains and posits options to those issues. Learn Half 1 on the upgradeability crisis here and Half 2 on the vertical scaling crisis here.
Upgradeability, vertical scaling and governance: What all three of those points have in frequent is that individuals are trying to iterate on high of a flawed structure. Bitcoin and Ethereum had been so transformative that they’ve completely framed the way in which we take a look at these points.
We have to keep in mind that these had been developed at a selected second in time, and that point is now within the somewhat-distant previous when blockchain expertise was nonetheless in its infancy. One of many areas through which this age is displaying is in governance. Bitcoin launched with proof-of-work to ascertain Byzantine fault tolerance and ship the decentralization essential to create a trustless ledger that can be utilized to host digital cash.
With Ethereum, Vitalik Buterin was searching for to generalize the underlying expertise in order that it could possibly be used not simply to host digital cash but in addition to allow builders to program that cash. With that objective in thoughts, it made good sense to undertake the consensus algorithm behind probably the most trusted blockchain: proof-of-work.
Proof-of-work is a mechanism for minimizing Byzantine fault intolerance — proving BFT isn’t as straightforward as folks prefer to fake. It isn’t a governance system. Bitcoin doesn’t want a governance system as a result of it’s not a general-purpose laptop. The explanation general-purpose computer systems want a governance system is that computer systems must be upgraded.
One wants no clearer proof than the magnitude of adjustments deliberate for Ethereum 2.zero and the aggressive advocacy for the adoption of the mandatory exhausting forks. We aren’t the primary to level out this drawback. The founders of Tezos precisely forecast this drawback, however they in the end did not ship a protocol that meets the wants of most builders for the next causes:
- The blockchain is written in a special language than the sensible contracts.
- They launched a political course of the place decision-making happens off-chain.
- They did not ship on an on-chain express improve path.
- They failed to ascertain distinct courses that may act as checks and balances.
The smartness of sensible contracts
Builders should be capable to code up the behaviors they wish to see within the blockchain as sensible contracts, and there should be an on-chain course of for including this conduct to the system by means of an express improve path. Briefly, we should always be capable to see the historical past of an improve simply as we will see the historical past of a given token.
The suitable place for governance is in figuring out which sensible contracts are made into “system” contracts primarily based on whether or not they’ll enhance the worth of the protocol. The problem is, after all, coming to a consensus on that worth.
Essentially the most controversial level I’ll make is the vital want for algorithmically distinct courses that act as checks and balances on each other. Whereas instinct would possibly recommend that extra courses make consensus harder, this isn’t the case.
First, if the improve candidates are already working as sensible contracts on the mainnet, goal metrics can be utilized to find out whether or not the ecosystem would profit from turning the “person” contract right into a “system” contract. Second, if we weren’t attempting to bundle upgrades into exhausting forks, they could possibly be piecemeal and focused. We’d merely be attempting to evaluate, in a decentralized method, whether or not the system can be improved by a single change.
Checks and balances
It’s generally understood that in any economic system, there are basically three elements of manufacturing: land (infrastructure), labor and capital. Each main blockchain solely acknowledges one class: capital. In PoW chains, those that have probably the most capital purchase probably the most ASICs and decide which upgrades can undergo. In proof-of-stake and delegated proof-of-stake chains, management by capital is extra direct.
Along with being problematic on its face, the absence of every other courses to behave as a verify on capital has a paradoxical impact that results in political paralysis. No group is homogenous. Courses, correctly measured, create effectivity — not inefficiency — by forcing the members of a category to come back to a consensus round their frequent curiosity. With out such stress, subclasses (teams inside a category) will struggle amongst each other, resulting in gridlock. Correctly designed courses inspire their members to come back to an inner consensus in order that they will maximize their affect on the system relative to the opposite courses.
If we will codify particular person courses representing infrastructure, improvement and capital, then upgrades that obtain approval from all three courses should, by definition, add worth to the protocol, as these three courses embody the totality of stakeholders inside any economic system.
Such a governance system, when mixed with a extremely upgradeable platform, would be capable to quickly adapt to the wants of builders and end-users, and evolve right into a platform that may meet the wants of everybody.

Andrew Levine is the CEO of OpenOrchard, the place he and the previous improvement crew behind the Steem blockchain construct blockchain-based options that empower folks to take possession and management over their digital selves. Their foundational product is Koinos, a high-performance blockchain constructed on a wholly new framework architected to offer builders the options they want with the intention to ship the person experiences essential to unfold blockchain adoption to the plenty.
