It appears to me that there are various ways to build covenants and vaults with opcodes and sighash flags that are not yet enabled in Bitcoin (e.g. OP_CHECKTEMPLATEVERIFY, SIGHASH_ANYPREVOUT, OP_CAT).
Assuming these are considered for the next soft fork in Bitcoin (not a certainty) what downsides are there to just enabling all of them and seeing what people build with them?
Obviously taking up a reserved OP_NOP with a potentially suboptimal opcode is one downside. And in the worst case a botched opcode could mean that a UTXO might not be able to spent (or impose unacceptable verification costs on full nodes). Are there any other potential downsides?
I suppose this is partly answered by what motivated Satoshi to disable a lot of opcodes in 2010 which I’m not clear on. The motivation appears to be security but again I’m not clear on what exact attacks that were possible with what opcodes and the severity of those attacks.
Today we talk with Tom Anderson of Devvio. Blockchain technology has grown over the past decade by providing trustless and highly robust solutions for maintaining distributed ledgers. However, in spite of the many different blockchain approaches that currently exist, there are a number of challenges that have not been solved in a single solution. Various approaches provide parts of the solution, but a single protocol that addresses all of these major challenges is still needed. The Devv Protocol was designed component by component to solve all of the problems described above. The goal of Devvio is to create the first truly scalable blockchain, as it includes a full set of needed capabilities in order to grow with minimal impact to operating costs, such as its sharding approach and its Devvnero implementation for fraud, theft, and loss.
Vitalik nerd rages out at a conference! Plus, Kora is building a more inclusive financial system on the blockchain, through infrastructure for community-owned financial services ecosystems. The goal is to provide low-cost, universal access financial services for everyone. We feature Maomao Hu from Kora on todays episode because it is absolutely crucial in bringing financial services to outcasts markets.
