<h3>SYNOPSIS</h3>
<div>KVS is the light version of client interface on top of BTREE database
abstractions strive to support the basic features: </div>
<div>
<ul>
<li>Polymorphic tuples aka extensible records;</li>
<li>Basic schema for chain storage;</li>
<li>Backends: MNESIA, FS, ROCKS;</li>
<li>Extremely compact and battle-tested: 500 LOC.</li>
</ul>
</div>
<div>This is an essence and fruit of KVS; the abstract term interface
with naive yet productive stream implementation. Useful for simple
blockchains, messaging, storage, processing systems, and banking industry.
KVS is used in BPE and BANK applications.</div>
