Such an approach has many benefits. =

Thus this approach allows for equivalent but = alternate implementations. Consequently, this approach = -

1. increases the available pool of = developers
2. reduces the impact any one implementation defect = can have on the overall Bitcoin infrastructure
3. allows = enhancement/optimization work of modules to proceed more easily as = coupling with external modules is = reduced

Second, and just as important, = it allows analysis and critiquing of Bitcoin's infrastructure to be = undertaken at a higher level than source code: i.e. abstract entities of = the protocols and APIs.  Such scrutiny is important to being able = to effectively manage the evolution of a system's = architecture.

One of the primary = upcoming priorities for bitcoin=92s infrastructure, beyond the bloom = filter, will be the continued modularization of the system.

Taking on a project of this scope is a highly = intensive, technical undertaking and we believe excellent developers = should be compensated as such, especially when it comes to open source = projects.

One of the main goals will be to separate the = wallet from the node, as we have already done with mining.
